General Findings. The Dublin City Council makes the following general findings regarding local climatic, geologic, and topographical conditions, which the City Council finds necessitates the local modifications to the California Building Standards Code set forth below: 1. Local climatic conditions include a low amount of average yearly rainfall, which tends to be concentrated from October through April. From May through September, a dry period occurs where daily temperatures remain high and there is little measurable precipitation. In addition, the local climate frequently includes high winds which sweep down through the valley. As a result of the high summer temperatures, average load demand and peak load demand of energy used in Dublin are important factors impacting public safety and creating the potential for adverse economic impacts due to power outages or power reductions (i.e. “brownouts”). As a result of the low precipitation, the area is subject to occasional drought. In developed areas of the City, fires can occur in buildings, rubbish, automobiles, and grass fires on vacant lots. In the undeveloped areas of the City, there is a risk of large brush and grass fires. If a fire occurs in either a developed or undeveloped area of the City, the local dry conditions combined with high winds, creates the risk of a potential fire storm. In addition, local residential and commercial development is occurring in previously undeveloped areas adjacent to wildfire urban interface areas. These new developments increase the chance of fire while simultaneously being located further from fire stations, delaying critical response times. This potential problem can be mitigated by requiring initial fire control through the installation of automatic fire protection systems. 2. Local geologic conditions include a risk of earthquake. A number of earthquake faults are located either within or in close proximity to the City. Those with the most direct and potentially destructive impact are the San Andreas, Calaveras, Hayward, Greenville and Concord-Green Valley Faults. History of earthquake activity indicates that there is a likelihood of a major earthquake in the area. The largest recorded earthquake in this immediate area occurred on the San Andreas Fault on October 17, 1989, a 7.1 magnitude. This area had a sequence of earthquakes on the Greenville Fault in January and February of 1980; these earthquakes had a magnitude of 5.5 to 5.9 on the Richter Scale and in July 2019 the Greenville Fault had an earthquake of 4.3. The U.S. Geological Survey (USGS) has identified a 72% probability of a major (6.7 or larger) earthquake occurring in the region within the next 20 years (Source – USGS UCERF3 report). Earthquake damage studies, including the 1994 Northridge earthquake, have indicated the lack of adequate design and detailing as a Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 2 of 83 contributing factor to damages that reduced the protection of the life-safety of building occupants. In the event of an earthquake, damage to structures can be expected. In residential and commercial areas, this could include significant damage or collapse of buildings. Secondary impacts could include ruptured electric or gas connections and/or breaks in water distribution lines. The potential for a major seismic event would create a City-wide demand for emergency response and fire protection service which would exceed staff response capacity. This potential problem can be mitigated by requiring initial fire control through the installation of automatic fire protection systems. 3. Local topographical conditions include hills on the western and eastern boarders and flat area in the center of the City. Interstate 680 divides the City into two sections, and circulation between areas of the City rely on freeway overpasses. In addition, local traffic must also pass over railroad tracks, creeks, and bridges (to cross arroyos). During peak a.m. and p.m. traffic periods, the City experiences heavy traffic congestion at key intersections, and near many freeway on-ramp and off-ramps. In the event of an accident or emergency at one of these key intersections, bridges, or other circulation corridors, sections of the City could become isolated and response times increased beyond ideal levels. Again, this potential problem can be mitigated by requiring initial fire control through the installation of automatic fire protection systems. 4. Based on the local climatic, geologic, and topographical conditions outlined above, there is a real risk that emergency response could be significantly delayed in the event of an accident or emergency. Therefore, it is necessary to address this problem through the requirement of additional mitigation measures to: (i) prevent the chance of accident or injury by requiring standards more stringent than required by the current codes; and (ii) requiring additional built-in automatic fire protection systems which will provide for early detection and initial fire control. 5. The burning of fossil fuels used to heat structures, heat water for cooking, and for other uses is a significant contributor to greenhouse gas emissions and climate change. Combustion of natural gas and petroleum products for heating and cooking needs emit carbon dioxide, methane, and nitrous oxide. Emissions from natural gas consumption represented 46% of the total annual U.S. energy related CO2 emissions in 2021. (See U.S. Energy Information Administration, “Where Greenhouse Gases Come From”, 2021.) Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the ‘greenhouse effect’ warming that results when the atmosphere traps heat radiating from Earth towards space. Long lived gases such as carbon dioxide can persist in the atmosphere for more than 100 years, even with efforts to reduce emissions today. Nitrous oxide, carbon dioxide, and methane are gases that contribute to the greenhouse gas effect. (See NASA, Causes of Climate Change, as of November 25, 2020.) Global climate change imposes substantial and local impacts and risks on the San Francisco Bay Area, and thus the City of Dublin, including rising temperatures, changing precipitation Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 3 of 83 patterns and amounts, sea level rise, flooding, drought, and wildfire, A general summary of climate risks facing the San Francisco Bay Area and the City of Dublin are as follows: • Increased temperatures and extreme heat events. The Bay Area is expected to see an increase in average annual temperature of 2.7°F by 2050, and 3.5°F to 11°F by 2100. • Reduction in the Quality and Supply of Water in the Sierra Snowpack. If heat- trapping emissions continue unabated, more precipitation will fall as rain instead of snow, and the snow that does fall will melt earlier, reducing the Sierra Nevada spring snowpack by as much as 70% to 90%. This can lead to challenges in securing adequate water supplies. It can also lead to a potential reduction in hydropower. • Changes in Rainfall Intensity. By mid-century, more precipitation is projected to occur in winter in the form of less frequent but larger events. Most climate models predict drying trends across the State by 2100. • Increased Risk of Large Wildfires. A hotter, drier climate could promote up to 90% more Northern California fires by the end of the century by drying out and increasing the flammability of forest vegetation. • Exacerbation of Air Quality Problems. If temperatures rise to the medium warming range, there could be 75% to 85% more days with weather conducive to ozone formation, relative to today’s conditions. This is more than twice the increase expected if rising temperatures remain in the lower warming range. This increase in air quality problems could result in an increase in asthma and other health-related problems. The average air quality index in Dublin has consistently worsened over time and is lower than the State and national averages; it also worsens during extreme heat and wildfire events. As the air quality index increases, and increasingly large percentage of the Dublin population is likely to experience increasingly adverse health effects. All-electric construction has a significant positive effect on energy resource efficiency, waste and pollution generation, and the health and productivity of building occupants over the life of the building. The City of Dublin has a dry, hot period of at least five months each year. As a result of the high temperatures, average load demand and peak load demand of energy used in Dublin are important factors impacting public safety and creating the potential for adverse economic impacts due to power outages or power reductions (i.e. “brownouts”). Reduction of total and peak energy use because of incremental conservation measures required by this ordinance will have local benefits in the additional available system energy capacity. Furthermore, the reduction of greenhouse gas emissions from all- electric buildings will help mitigate climate change and its negative effects such as extreme heat events, droughts, intense storms, and flooding, thus making these amendments reasonably necessary because of local climactic reasons. 6. The San Francisco Bay area region is densely populated and located in an area of high seismic activities. Concern for fire-life safety associated with gas appliances and associated piping located in the ground and in buildings increases with the risk of explosion or fire if there is a structural failure due to a seismic event considering the increasing number of buildings in the region. Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 4 of 83 The risk of natural gas infrastructure and pipeline explosions and fires are magnified in cases of major earthquakes, for example, the 2010 San Bruno pipeline explosion. Severe seismic events could disrupt communications, damage gas mains, and place increased demands on the dispersed resources of the Fire Department necessary for the life safety needs of the community.

The building codes adopted by section 7.32.030 and the provisions of this Chapter shall constitute the Dublin Building Code and may be referred to as such. FINDING: Administrative – finding not required. 7.32.020 Purpose. The promotion and preservation of the public health, safety and general welfare of the people of the City and the property situated therein have made necessary the adoption of the building codes referred to in Section 7.32.030 in order to adequately safeguard life, health, property, and general welfare. The purpose of this Code is not to create or otherwise establish or designate any particular class or groups of persons who will or should be especially protected or benefited by the terms of this Code. FINDING: Administrative – finding not required. 7.32.030 Adoption of Building Codes. A. The 2025 California Building Code, Part 2, Title 24 of the California Code of Regulations, a portion of the California Building Standards Code, as defined in the California Health and Safety Code Section 18901 et. seq. (hereinafter referred to as the "State Code"), and any rules and regulations promulgated pursuant thereto including the International Building Code, 2024 Edition, including Appendix Chapters, F, G, H, and I, , as published by the International Code Council, and as referenced in and adopted pursuant to California Health and Safety Code Sections 17922 and 18935, (hereinafter referred to as the "IBC") are hereby adopted and incorporated by reference herein. The codes and standards referenced in this code shall be considered part of this code to the prescribed extent of each such reference. Where the extent of the reference to a referenced code or standard includes subject matter that is within the scope of this code or the Mechanical, Plumbing, Housing, Fire or Energy Codes, the provisions of these codes as applicable, shall take precedence over the provisions in the referenced code or standard. Copies of the adopted codes have been and are now filed in the Office of the Building Official, 100 Civic Plaza, Dublin, California, for use and examination by the public. Said codes are adopted by reference pursuant to Section 50022.4, et seq., of the Government Code of the State of California, and the codes are hereby adopted and incorporated as fully as if set out at length herein, and from the date on which this Ordinance shall take effect, the provisions thereof shall be controlling within the limits of the City of Dublin. B. Notwithstanding the provisions of Section 7.32.030.A, the State Code and the International Building Code are amended as set forth in Sections 7.32.110 through 7.32.300.

Additionally, the area is subject to occasional drought. These climate issues bring rodents from the fields into the housing stock to find water and food in the dry portion of the year and shelter in the rainy season. Appendix Chapter G flood resistant construction This modification is necessary because the City of Dublin is a densely populated area having buildings and structures constructed near and within flood prone areas. The City codes require a definition for Substantial Damage and Substantial Improvement that includes repetitive loss and repetitive flood damage. Local climatic and topographical conditions include an average yearly rainfall, which tends to be concentrated from October to April. Appendix Chapter H signs The amendment is needed due to local climatic and topographical conditions. This modification was necessary due to the City of Dublin’s basic wind speed requirement relating to the high winds described in Section A of these Findings. Appendix Chapter I, this appendix chapter is adopted by the State and therefore is not required to have findings. 7.32.040 Scope. A. The provisions of this Code shall apply to the installation, erection, construction, enlargement, addition to, alteration, repair, relocation, removal, demolition, conversion, replacement, equipment, use and occupancy, location, replacement, and maintenance of every building or structure or any appurtenances connected or attached to such buildings or structures within the City. B. The permissive provision of this Code shall not be presumed to waive any limitations imposed by any other law, ordinance, rule, or regulation.

Buildings shall be made accessible to persons with disabilities as required by Title 24 California Code of Regulation. Whenever there is a conflict between the provisions of this Code and Title 24, California Code of Regulations with respect to the accessibility of buildings to persons with disabled, the provisions of Title 24 shall prevail. FINDING: Administrative – finding not required. 7.32.050 Exceptions. The provisions of this Code shall not apply to: A. Work located in a public street; B. Trailer coaches, campers, mobile homes, motor vehicles, railroad cars, and aircraft; however, if any of the foregoing are permanently placed on the ground or have their wheels removed for other than temporary repairs, they shall comply with all of the provisions of this Code; C.

Buildings or structures to which additions, alterations, or repairs are made shall comply with all the requirements of this Code for new buildings or structures except as specifically provided for in this section and Sections 7.32.070 through 7.32.100. FINDING: Administrative – finding not required. 7.32.070 Additions, alterations and repairs-Code compliance. Additions, alterations or repairs may be made to any building or structure without requiring the existing building or structure to comply with all the requirements of this Code, provided the addition, alteration or repair conforms to that required for a new building or structure. Additions or alterations shall not be made to an existing building or structure which will cause the existing building or structure to be in violation of any of the provisions of this Code nor shall such additions or alterations cause the existing building or structure to become unsafe. An unsafe condition shall be deemed to have been created if an addition or alteration will cause the existing building or structure to become structurally unsafe or overloaded; will not provide adequate egress in compliance with the provisions of this Code or will obstruct existing exits; will create a fire hazard; will reduce required fire resistance or will otherwise create conditions dangerous to human life. Any building so altered, which involves a change in use or occupancy, shall not exceed the height, number of stories and area permitted for new buildings. Any building plus new additions shall not exceed the height, number of stories and area specified for new buildings. Additions or alterations shall not be made to an existing building or structure when such existing building or structure is not in full compliance with the provision of this Code.

The provisions of Section 7.32.070 shall not prohibit the alteration or repair of any legally established existing apartment house, hotel, dwelling or structure accessory thereto which retains, replaces or extends the use of the original materials or continued use of original methods of construction provided such alteration or repair does not create or continue a dangerous building as defined in Section 7.28.220, a substandard building as defined in Section 7.28.090 of the Dublin Municipal Code. However, such alteration or repair shall not reduce any required fire resistance below that specified by this Code, reduce the resistance to lateral forces below that specified by Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 18 of 83 this Code, or increase the stress or deflection of any member so as to exceed that specified by this Code. B. The provisions of Section 7.32.070 pertaining to additions shall not require any legally existing apartment house, hotel, dwelling, or structure accessory thereto to be made to conform to the provisions of this Code solely because of the construction of the addition. However, this section shall not be construed to permit the addition to increase the stress or deflection of any existing member so as to exceed that specified by the building code. Whenever an addition increases the number of occupants which must exit through the existing building all of the exit facilities serving the increased number of occupants shall comply with the provisions of this Code. C. Whenever a new dwelling unit is created either by new construction, or by an alteration to an existing building, separate gas and electrical meters shall be provided. FINDING: Administrative – finding not required. 7.32.090 Additions-Apartment houses, hotels and dwellings. Notwithstanding the provisions of Section 7.28.240 whenever alterations, repairs, or additions requiring a permit or one (1) or more sleeping rooms are added or created in existing Group R Occupancies, the entire building shall be provided with smoke alarms and carbon monoxide alarms located as required for new Group R Occupancies. Furthermore, spark arrestors shall be installed on all chimneys connected to solid burning fuel- burning appliances. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary because the City of Dublin has a dry period of at least five months each year. Additionally, the area is subject to occasional drought. Because of dryness, a rapidly burning grass fire or exterior building fire can quickly transfer to other buildings. These modifications are consistent with the Fire Authority having jurisdiction. 7.32.100 Repair of roof covering. Roof coverings may be repaired or replaced with materials as set forth in Section 7.32.180. FINDING: Administrative – finding not required. 7.32.110 Chapter 1 Division II, Administration-Deleted.

Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. The term also includes flood-related damage sustained by a structure on two separate occasions during a 10-year period for which the cost of repairs at the time of each such flood event, on average, equals or exceeds 25 percent of the market value of the structure before the damage occurred. Substantial Improvement. Any one or more or any combination of repair, reconstruction, rehabilitation, alterations, addition or other improvement of a building or structure taking place during a 10-year period, the cumulative cost of which equals or exceeds 50 percent of the market value of the structure before the improvement or repair is started. For each building or structure, the 10-year period begins on the date of the first permit issued for improvement or repair of that building or structure subsequent to January 1, 2023. If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The term does not, however, included either: 1. Any project for improvement of a building required to correct existing health, sanitary or safety code violations identified by the building official and that are the minimum necessary to assure safe living conditions. 2. Any alteration of a historic structure provided that the alteration will not preclude the structure’s continued designation as a historic structure. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification is necessary because the City of Dublin is a densely populated area having buildings and structures constructed near and within flood prone areas. The City codes require a definition for Substantial Damage and Substantial Improvement that includes repetitive loss and repetitive flood damage. Local climatic and topographical conditions include an average yearly rainfall, which tends to be concentrated from October to April. 7.32.125 Section 310.1.1, Chapter 3, Accessory Dwelling Unit Occupancy – Added. Section 310.1.1 is added to read: 310.1.1 Accessory Dwelling Unit Occupancy. Construction of an accessory dwelling unit shall not constitute a Group R occupancy change under the building code, unless the Building Official makes a written finding based on substantial evidence in the record that the construction of the accessary dwelling unit could have a specific, adverse impact on public health and safety. Nothing in this paragraph shall be interpreted to prevent the Building Official from changing the occupancy code of a space that was unhabitable or was only permitted for non-residential use and was subsequently converted for residential use pursuant to Government Code Section 66314.(d)(8). FINDING: The amendment is required to be consistent with Government Code Section 66314.(d)(8). Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 20 of 83 7.32.130 Sections 502.2.1, 502.2.2, 502.2.3, 502.2.4, Chapter 5, Address illumination – Added.

FINDING: The amendment is needed due to local geological and topographical conditions. These modifications are necessary due to the topographical nature of the City and the easy access to freeways described in Section A of these Findings. In light of said conditions, it is necessary to adopt these requirements to enhance crime prevention. Additionally, this will bring the code into conformance with the City of Dublin Police Department requirements. 7.32.140 Section 507.14, Chapter 5, Frontage Restriction-Added. A new Section 507.14 is added to read: 507.14 Frontage Restriction.

Such agreement shall be recorded in the Alameda County Recorder's Office. Exception: When using the public way for frontage increase. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary because the City of Dublin has a dry period of at least five months each year. Additionally, the area is subject to occasional drought. Because of dryness, a rapidly burning grass fire or exterior building fire can quickly transfer to other buildings. These modifications are consistent with the Fire Authority having jurisdiction.

These modifications are necessary because the City of Dublin has a dry period of at least five months each year. Additionally, the area is subject to occasional drought. Because of dryness, a rapidly burning grass fire or exterior building fire can quickly transfer to other buildings. These modifications are consistent with the Fire Authority having jurisdiction. Addition of Sections 903.2.8 Exception 5 and 6 are added to be consistent with Government Code Sections 66314(d)(12) and 66323(d). 7.32.190 Section 1505.1, Chapter 15, Fire Classification-Amended. Section 1505.1 is amended to read: 1505.1 General. Roof Assemblies shall be divided into the classes defined below. Class A, B, and C roof assemblies and roof coverings required to be listed by this section shall be tested in accordance with ASTM E 108 or UL 790. In addition, fire-retardant-treated wood roof coverings shall be tested in accordance with ASTM D 2898. The minimum roof coverings installed on buildings shall comply with the following: 1.

Any new roof for buildings using roof covering material Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 24 of 83 that conforms to Class C or better or shall be made of concrete, ferrous or copper metal, clay, slate or similar non-combustible material. 4. Other Occupancies. Any new roof covering and any alterations, repairs or replacement of roof covering material for buildings housing all other occupancies shall conform to the requirements as set forth in Roofing Area 1. * Editor's Note: Figure 15-1 is on file in the office of the City Clerk. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary because the City of Dublin has a dry period of at least five months each year. Additionally, The area is subject to occasional drought. Because of dryness, a rapidly burning grass fire or exterior building fire can quickly transfer to other buildings. These modifications are consistent with the Fire Authority having jurisdiction. 7.32.200 Table 1607.1, Chapter 16, Minimum Uniformly Distributed Live Loads, Lo, and Minimum Concentrated Live Loads -Amended. Table 1607.1 is amended by adding a new Footnote e to read: e. Bridges for vehicular traffic shall be designed for H20 loading as designated by the American Association of State Highway Officials. FINDING: The amendment is needed due to local geological, climatic and topographical conditions. This modification was necessary because bridges were not addressed by the Building Code. Additionally, due to the City’s terrain a number of bridges and overpasses may be required. 7.32.210 Section 1705.3 Exception 1, Chapter 17, Concrete Construction – Amended. Section, 1705.3 Exception 1 is amended to read: 1. Isolated spread concrete footings of buildings three stories or less above grade plane that are fully supported on earth or rock, where the structural design of the footing is based on a specified compressive strength, f’c, no greater than 2,500 pounds per square inch (psi) (17.2 Mpa) regardless of the compressive strength specified in the construction documents or used in the footing construction. FINDING: The amendment is needed due to local geological conditions. Results from studies after the 1994 Northridge earthquake indicated that a lot of the damage was attributable to the lack of quality control during construction and therefore needs to be incorporated into the Code. Revise CBC Section 1705.3 exception No. 1 to allow special inspection not to be required for isolated Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 25 of 83 spread footings where the structural design of the footing is based on a specified compressive strength, f’c no greater than 2,500 psi. 7.32.220 Section 1905.6.2 Seismic Design Categories C, D, E and F—Amended. Section, 1905.6.2 Seismic Design Categories – Amended Structures assigned to Seismic Design Category C, D, E or F shall not have elements of structural plain concrete, except as follows: (1) Isolated footings of plain concrete supporting pedestals or columns are permitted, provided the projection of the footing beyond the face of the supported member does not exceed the footing thickness. Exception: In detached one- and two-family dwelling three stories or less in height, the projection of the footing beyond the face of the supported member is permitted to exceed the footing thickness. (2) Plain concrete footing supporting walls are permitted, provided the footings have no fewer than two continuous longitudinal reinforcing bars. Bars shall not be smaller than No. 4 and shall have a total area of not less than 0.002 times the gross cross-sectional area of the footing. Not fewer than one bar shall be provided at the top and bottom of the footing. Continuity of reinforcement shall be provided at corners and intersections. FINDING: The amendment is needed due to local geological, climatic and topographical conditions. This amendment addresses the problem of poor performance of plain or under reinforced concrete footings during a seismic event. This amendment reflects the recommendations by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Joint Task Force that investigated the poor performance of plain and under-reinforced concrete footings observed in the 1994 Northridge earthquake. The San Francisco Bay area region is densely populated and/or located in an area of high seismic activities as indicated by United States Geological Survey and California Division of Mines and Geology. Earthquake activities, including the 1989 Loma Prieta earthquake, have indicated the lack of adequate design and detailing as a contributing factor to damages that reduced the protection of the life-safety of building occupants. The City of Dublin is a densely populated area having buildings constructed near potentially active faults. The Association of Bay Area Governments (ABAG) roughly estimates the probability of a serious earthquake along the Hayward Fault as one-in-four in the next 20 years, while the USGS predict the probability of a powerful quake in the next 20 years at 72%. The proposed modification to ensure that the design of slender wall must satisfy both strength and serviceability requirements need to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the International Building Code. Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 26 of 83 7.32.230 Table 2308.10.1, Chapter 23, Wall Bracing Requirements–Amended. Table 2308.10.1 is amended by adding new footnotes “f” and “g” to read: f. Methods PBS, HPS, and SFB are not permitted in Seismic Design Category D and E. g. Methods GB, DWB and PCP are not permitted in Seismic Design Category E. FINDING: The amendment is needed due to local geological conditions. This amendment addresses the problem of poor performance of wall bracing materials in high seismic areas. Shear walls sheathed with lath, plaster or gypsum board are less ductile than plywood shear walls. The poor performance of such shear walls in the 1994 Northridge earthquake was investigated by the Structural Engineers Association of Southern California (SEAOSC) with the Los Angels City Task Force and formed the basis for this amendment. This amendment is consistent with shear wall restrictions by the American Wood Council (Section 4.3.47 SDPWS) and ICC ESR-1338 for Gypsum Board. 7.32.240 Section 2308.6.10.9, Attachment of Sheathing-Amended. Section 2308.6.10.9, is amended by adding a second paragraph: All braced wall panels shall extend to the roof sheathing and shall be attached to parallel roof rafters or blocking above with framing clips (18 gauge minimum) spaced at maximum 24 inches (6096 mm) on center with four 8d nails per leg (total eight 8d nails per clip). Braced wall panels shall be laterally braced at each top corner and at maximum 24 inches (6096 mm) intervals along the top plate of discontinuous vertical framing. FINDING: The amendment is needed due to local geological, climatic and topographical conditions. The San Francisco Bay area region is densely populated and/or located in an area of high seismic activities as indicated by United States Geological Survey and California Division of Mines and Geology. Earthquake activities, including the 1989 Loma Prieta earthquake, have indicated the lack of adequate design and detailing as a contributing factor to damages that reduced the protection of the life-safety of building occupants.

Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 27 of 83 A new Section 3115.1 is added to read: 3116.1 Prohibited Installations. It shall be unlawful to install a wood burning fireplace or wood burning appliance that is not one of the following: 1) Pellet-fueled wood heater, 2) EPA certified wood heater, 3) Fireplace certified by EPA FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary because fireplaces and wood stoves generate 40 percent of the particulate matter in the Bay Area during the winter months. Of greater concern are the fine particles, which can lodge deep in the lungs causing permanent lung damage and increasing mortality. Burning wood also generates carbon monoxide, nitrogen dioxide, volatile organic and toxic air pollutants. 7.32.260 Section 3203, Chapter 32, Signs-Added. A new Section 3203 is added to read: 3203 Signs. Signs when placed flat against the wall of a building shall not project beyond the front property line more than 12 inches (305mm). FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary due to the City of Dublin’s basic wind speed requirement relating to the high winds described in Section A of these Findings. 7.32.270 Section H101.2, Signs exempt from permits -Deleted. Section H101.2 is deleted. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary due to the City of Dublin’s basic wind speed requirement relating to the high winds described in Section A of these Findings. 7.32.280 Section 1010, Appendix Chapter 10, Building security – Added. Appendix Chapter 10 is added to read: Section 1010 building security shall be in accordance with the Uniform Building Security Code in addition to the following: * Editor's Note: See Chapter 7.34 Residential Code for single family or townhouse requirements.

The definitions of “Substantial Damage” and “Substantial Improvement” in Section 202 of the State Code are amended to read as follows: Substantial Damage. Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. The term also includes flood-related damage sustained by a structure on two separate occasions during a 10-year period for which the cost of repairs at the time of each such flood event, on average, equals or exceeds 25 percent of the market value of the structure before the damage occurred. Substantial Improvement. Any one or more or any combination of repair, reconstruction, rehabilitation, alterations, addition or other improvement of a building or structure taking place during a 10-year period, the cumulative cost of which equals or exceeds 50 percent of the market value of the structure before the improvement or repair is started. For each building or structure, the 10-year period begins on the date of the first permit issued for improvement or repair of that building or structure subsequent to January 1, 2023. If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The term does not, however, include either: 1. Any project for improvement of a building required to correct existing health, sanitary or safety code violations identified by the building official and that are the minimum necessary to assure safe living conditions. 2. Any alteration of a historic structure provided that the alteration will not preclude the structure’s continued designation as a historic structure. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification is necessary because the City of Dublin is a densely populated area having buildings and structures constructed near and within flood prone areas. The City codes require a definition for Substantial Damage and Substantial Improvement that includes repetitive loss and repetitive flood damage. Local climatic and topographical conditions include an average yearly rainfall, which tends to be concentrated from October to April.

Earthquake activities, including the 1989 Loma Prieta earthquake, have indicated the lack of adequate design and detailing as a contributing factor to damages that reduced the protection of the life-safety of building occupants. The City of Dublin is a densely populated area having buildings constructed near potentially active faults. The Association of Bay Area Governments (ABAG) roughly estimates the probability of a serious earthquake along the Hayward Fault as one-in-four in the next 20 years, while the USGS predict the probability of a powerful quake in the next 20 years at 72%. The proposed modification to ensure that the design of slender wall must satisfy both strength and serviceability requirements need to be incorporated into the code to assure that new buildings and additions to existing buildings are designed and constructed in accordance with the scope and objectives of the International Building Code. 7.34.220 Table R602.10.3(3), Chapter R6, Bracing Requirements – Amended. Table R602.10.3(3) is amended by adding a new footnote “i” to read: i. Methods PBS, HPS, SFB and CS-SFB are not permit in Seismic Design Categories D0, D1, and D2 . j. Methods GB, DWB and PCP are not permitted in Seismic Design Categories D0, D1, and D2 where S1 is greater than or equal to 0.75. Add the “i, j” footnote notation in the title of Table R602.10.3(3) to read: TABLE R602.10.3(3)i, j FINDING: The amendment is needed due to local geological, climatic and topographical conditions. The amendment addresses the problem of poor performance of these bracing materials in high seismic areas to limit potential structural damage. Shear walls sheathed with lath, plaster or gypsum board are less ductile than plywood shear walls, The poor performance of such shear walls in the 1994 Northridge earthquake was investigated by the Structural Engineers Association of Southern California (SEAOSC) and the Los Angeles City Task Force and formed the basis for this amendment. This amendment is also consistent with the design limitations for similar shear walls found in Table 2308.6.1 of the 2022 California Building Code. Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 50 of 83 7.34.230 Section R602.10.4.5, Chapter R6, Limits on methods GB and PCP – Added. A new Section R602.10.4.5 is added to read: R602.10.4.5 Limits on methods GB and PCP. In Seismic Design Categories D0, D1, and D2, Method GB is not permitted for use as intermittent braced wall panels, but gypsum board is permitted to be installed when required by this Section to be placed on the opposite side of the studs from other types of braced wall panel sheathing. In Seismic Design Categories D0, D1, and D2, the use of Method PCP is limited to one-story single-family dwellings and accessory structures. FINDING: The amendment is needed due to local geological, climatic and topographical conditions. This section deletes the use of gypsum board for lateral bracing. This deletion is necessary because the City of Dublin is located in Seismic Zone D and E. Gypsum wallboard has performed poorly during California seismic events. The shear values for gypsum wallboard contained in the code are based on mono- directional testing. In addition, this section limits the use of portland cement plaster for lateral bracing to single story residential buildings. This limitation is necessary because the City of Dublin is located in Seismic Zone D and E. Exterior portland cement plaster has performed poorly during California seismic events. The shear values for portland cement stucco contained in the code are based on mono-directional testing. It is appropriate to limit the use of this product until cyclic loading tests are performed and evaluated. The San Francisco Bay Area region is densely populated and/or located in an area of high seismic activities as indicated by United States Geological Survey and California Division of Mines and Geology. Earthquake activities, including the 1989 Loma Prieta earthquake, have indicated the lack of adequate design and detailing as a contributing factor to damages that reduced the protection of the life-safety of building occupants.

Section R902.1 is amended to read: Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 51 of 83 R902.1 Roof assemblies. Roof decks shall be covered with materials as set forth in Section R904 or with roof coverings as set forth in Section R905. A minimum Class A, B or C roofing shall be installed in areas designated below or where the edge of the roof deck is less than 3 fee (914 mm) from a lot line. Where Class A, B or C roof assemblies are required, they shall be tested in accordance with ASTM E108 or UL 790. Where required, the roof assembly shall be listed and identified as to class by an approved testing agency. 1. Map of Fire Safe Roof Areas. Figure 15-1* is a map of Fire Safe Roof areas. Said map may be amended from time to time by including areas which are annexed to the City within one of the two roofing areas. Said amendments may be made by the Building Official after consultation, with the Chief of the Fire Department or their designee having jurisdiction. 2. Roofing Area 1. Any new roof and any alteration, repair or replacement for buildings housing R & U-1 occupancies in Roofing Area 1 shall use roof covering material that conforms to Class B or better or shall be made of concrete, ferrous or copper metal, clay, slate or similar non-combustible material. 3. Roofing Area 2. Any new roof for buildings using roof covering material that conforms to Class C or better or shall be made of concrete, ferrous or copper metal, clay, slate or similar non-combustible material. * Editor's Note: Figure 15-1 is on file in the office of the City Clerk. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary because the City of Dublin has a dry period of at least five months each year. Additionally, The area is subject to occasional drought. Because of dryness, a rapidly burning grass fire or exterior building fire can quickly transfer to other buildings. These modifications are consistent with the Fire Authority having jurisdiction. 7.34.250 Section R1001.1.2 Chapter 10, Prohibited Installations—Added. A new Section R1001.1.2 is added to read: R1001.1.2 Prohibited Installations. It shall be unlawful to install a new wood burning fireplace or appliance that is not one of the following: 4) Pellet-fueled wood heater, 5) EPA certified wood heater, 6) Fireplace certified by EPA FINDING: The amendment is needed due to local climatic and topographical conditions. This modification was necessary because fireplaces and wood stoves generate 40 percent of the particulate matter in the Bay Area during the winter months. Of greater concern are the fine particles, which can lodge deep in the lungs causing Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 52 of 83 permanent lung damage and increasing mortality. Burning wood also generates carbon monoxide, nitrogen dioxide, volatile organic and toxic air pollutants. 7.34.260 Chapters 11 through 43 are Deleted.

When approved, such piping shall be installed in accordance with the following requirements: FINDING: The amendment is needed due to local geological conditions. This section eliminates water piping in or under concrete floor slabs within a building. This amendment is necessary for the following reasons: Most of the surface soils in the City of Dublin are relatively young and unconsolidated sedimentary materials formed from a wide variety of parent materials. The varying chemical composition, degree of weathering and the relatively acid environment have created soils of varying types, which are particularly corrosive in nature. Much of the surface soil in the City of Dublin is highly expansive (i.e., shrink-swell behavior) and have low bearing strength. There are two types of expansive soils in the area: a. the organic silty clays which are the bay muds; and b. the plastic silty clays which weather from the shale found in the hills surrounding the City of Dublin The local climate is characterized by markedly delineated rainy and dry seasons, which tend to maximize the expansive characteristics of soil. Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 59 of 83 Some parts of the City of Dublin have hard water, which is corrosive to ferrous pipe.

FINDING: Administrative – finding not required. 7.46.080 Section 202, Chapter 2, Definitions of Substantial Damage and Substantial Improvement. The definitions of “Substantial Damage” and “Substantial Improvement” in Section 202 of the State Code are amended to read as follows: Substantial Damage. Damage of any origin sustained by a structure whereby the cost of restoring the structure to its before-damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. The term also includes flood-related damage sustained by a structure on two separate occasions during a 10-year period for which the cost of repairs at the time of each such flood event, on average, equals or exceeds 25 percent of the market value of the structure before the damage occurred. Substantial Improvement. Any one or more or any combination of repair, reconstruction, rehabilitation, alterations, addition or other improvement of a building or structure taking place during a 10-year period, the cumulative cost of which equals or exceeds 50 percent of the market value of the structure before the improvement or repair is started. For each building or structure, the 10-year period begins on the date of the first permit issued for improvement or repair of that building or structure subsequent to January 1, 2023. If the structure has sustained substantial damage, any repairs are considered substantial improvement regardless of the actual repair work performed. The term does not, however, included either: 1. Any project for improvement of a building required to correct existing health, sanitary or safety code violations identified by the building official and that are the minimum necessary to assure safe living conditions. 2. Any alteration of a historic structure provided that the alteration will not preclude the structure’s continued designation as a historic structure. FINDING: The amendment is needed due to local climatic and topographical conditions. This modification is necessary because the City of Dublin is a densely populated area having buildings and structures constructed near and within flood prone areas. The City codes require a definition for Substantial Damage and Substantial Improvement that includes repetitive loss and repetitive flood damage. Local climatic and topographical conditions include an average yearly rainfall, which tends to be concentrated from October to April.

FINDING: Administrative – finding not required. 7.94.030 Adoption of the Green Building Code. A. The 2025 California Green Building Standards Code, Part 11, Title 24 of the California Code of Regulations, a portion of the California Building Standards Code, as defined in the California Health and Safety Code Section 18901 et. seq. (hereinafter referred to as the "State Code"), and any rules and regulations promulgated pursuant thereto, as referenced in and adopted pursuant to California Health and Safety Code Sections 17922 and 18935, are hereby adopted and incorporated by reference herein. Copies of the adopted codes have been and are now filed in the Office of the Building Official, 100 Civic Plaza, Dublin, California, for use and examination by the public. Said codes are adopted by reference pursuant to Section 50022.4, et seq., of the Government Code of the State of California, and the codes are hereby adopted and incorporated as fully as if set out at length herein, and from the date on which this Ordinance shall take effect, the provisions thereof shall be controlling within the limits of the City of Dublin. B. Notwithstanding the provisions of Section 7.94.030.A, the State Code is amended as set forth in Sections 7.94.050 through 7.94.080. FINDING: Administrative – finding not required. Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 67 of 83 7.94.040 Scope. A. The provisions of this Code shall apply to the planning, design, operation, construction, use and occupancy of every newly constructed building or structure, unless otherwise indicated in this Code, within the City. B. It is not the intent that this Code substitute or be identified as meeting the certification requirements of any green building program. FINDING: Administrative – finding not required. 7.94.050 Section 202, Chapter 2 Definitions – Amended. The following definitions are hereby added to Section 202 of the State Code to read as follows: ALL-ELECTRIC BUILDING. A building that contains no combustion equipment or plumbing for combustion equipment within the building or building property lines, and instead uses electric appliances for service. COMMERCIAL FOOD HEAT-PROCESSING EQUIPMENT. Equipment used in a food establishment for heat-processing food or utensils and that produces grease vapors, steam, fumes, smoke, or odors that are required to be removed through a local exhaust ventilation system, as defined in the California Mechanical Code. COMBUSTION EQUIPMENT. Any equipment or appliance used for space heating, water heating, cooking, clothes drying and/or lighting that uses fuel gas. ELECTRIC HEATING APPLIANCE. A device that produces heat energy to create a warm environment by the application of electric power to resistance elements, refrigerant compressors, or dissimilar material junctions, as defined in the California Mechanical Code. FUEL GAS. A gas that is natural, manufactured, liquefied petroleum, or a mixture of these. FINDING: The amendment is needed due to local climatic conditions. All-electric construction has a significant positive effect on energy resource efficiency, waste and pollution generation, and the health and productivity of building occupants over the life of the building. The City of Dublin has a dry, hot period of at least five months each year. As a result of the high temperatures, average load demand and peak load demand of energy used in Dublin are important factors impacting public safety and creating the potential for adverse economic impacts due to power outages or power reductions (i.e. “brownouts”). Reduction of total and peak energy use because of incremental conservation measures required by this ordinance will have local benefits in the additional available system energy capacity. Furthermore, the reduction of greenhouse gas emissions from all-electric buildings will help mitigate climate change and its negative effects such as extreme heat events, droughts, intense Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 68 of 83 storms, and flooding, thus making these amendments reasonably necessary because of local climactic reasons. 7.94.060 Section 4.106.4 Electric vehicle (EV) charging for new construction – Deleted and Replaced. Section 4.106.4 is deleted and replaced with Section A4.106.8 to read: A4.106.8 Electric vehicle (EV) charging for new construction is adopted as mandatory at the Tier 1 level. FINDING: The amendment is needed due to local climatic, topographical and environmental conditions. This modification is necessary because the City of Dublin is a densely populated area having buildings and structures constructed within heavily traveled traffic corridors and highways (580 and 680), near and within flood prone areas. This impacts the quality of the air, causes higher decibel noise level, and increases the risk of rising sea or flood levels. The proposed modification to increase the number of EV charging spaces will help to address and significantly reduce local air and noise pollutions, greenhouse gas emissions, and will improve the health and welfare of the City’s residents, businesses and visitors and reduce the rise in sea or flood levels that could put at risk the City’s homes, businesses and public facilities at risk. Therefore, this amendment needs to be incorporated into the code to assure that new buildings and structures and additions or alterations to existing buildings or structures are designed and constructed in accordance with the scope and objectives of the California Green Building Standards Code. 7.94.070 Sections 4.106.5, 4.106.5.1, and 4.106.5.2 All Electric Buildings – Added.

New construction and qualifying alteration projects. All newly constructed buildings shall be all-electric buildings. Qualifying alteration projects shall be limited to additions or alterations that remove 50 percent or more of the existing exterior walls of a dwelling and additions that increase the square footage of the structure by more than 50 percent. The final determination whether a project meets the definition of a qualifying alteration project shall be made by the Building Official Exception: If the applicant establishes that there is not an all-electric prescriptive compliance pathway for the building under the California Building Energy Efficiency Standards, and that the building is not able to achieve the performance compliance standard applicable to the building Docusign Envelope ID: 0AFCEC40-A09F-481A-82FE-6557DB57C900 Page 69 of 83 under the Energy Efficiency Standards using commercially available technology and an approved calculation method, then the Building Official may grant a modification. The applicant shall comply with the following and Section 4.106.5.2. Inactive Fuel Gas Infrastructure may be extended to spaces that are anticipated to qualify for the exceptions contained in this chapter. The inactive Fuel Gas Infrastructure shall not be activated, have a meter installed, or otherwise used unless the exemptions specified in this chapter have been confirmed as part of the issuance of a building permit. If the Fuel Gas Infrastructure is no longer serving one of the exceptions contained in this chapter, it shall either be capped, otherwise terminated, or removed by the entity previously entitled to the exemption, in a manner pursuant to all applicable Codes. The Building Official shall have the authority to approve alternative materials and methods of construction as per the Dublin Municipal Code, Chapter 7.28. 4.106.5.2 Requirements for combustion equipment. Where combustion equipment is allowed under subsection 4.106.5.1, the construction drawings shall indicate electrical infrastructure and physical space accommodating the future installation of an electrical heating appliance in the following ways, as certified by a registered design professional or licensed electrical contractor: 1.
