NOW, THEREFORE, the City Council of the City of Alameda does hereby ordain as follows:
SECTION 1: FINDINGS
A. Incorporation of Recitals. The above recitals are incorporated as findings into this Ordinance.
B. Statutory Findings. In enacting this Ordinance, City Council finds that each of the changes or modifications to measures referred to therein are reasonably necessary because of local climatic, geological, or topographical conditions in the area encompassed by the boundaries of the City of Alameda, and the City Council adopts the following findings in support of local necessity for the changes or modifications:
1. Climatic: The City is located in Climate Zone 3 as established in the 2025 California Energy Code. Climate Zone 3 incorporates mostly coastal communities from Marin County to southern Monterey County including San Francisco. The City experiences an average precipitation of approximately 23 inches per year. Ninety-five percent of precipitation falls during the months of November through April, leaving a dry period of approximately six months each year. Relative humidity remains moderate most of the time. Temperatures in the summer average around 80 degrees Fahrenheit and in the winter in the mid 50 degrees Fahrenheit. Prevailing winds in the area come from the west with velocities generally in the 12 miles per hour range, gusting from 25 to 35 miles per hour. These climatic conditions along with the greenhouse emissions generated from structures in both the residential and nonresidential sectors requires exceeding the energy standards for building construction established in the 2025 California Buildings Standards Code. The City Council also adopted a Climate Action and Resiliency Plan that has a goal of reducing greenhouse gas emissions 50% below 2005 levels by 2030. In order to achieve and maintain this goal, the City needs to adopt policies and regulations that reduce the use of fossil fuels that contribute to climate change, such as natural gas in buildings, in new development. Human activities, such as burning natural gas to heat buildings, releases greenhouse gases into the atmosphere and causes an overall increase in global average temperature. This causes sea levels to rise, affecting the City’s shoreline and infrastructure.
2. Geologic: The City of Alameda is subject to earthquake hazard caused by its proximity to both the Hayward and San Andreas faults. The San Andreas fault runs from Hollister, through the Santa Cruz Mountains, the epicenter of the 1989 Loma Prieta earthquake, up the San Francisco Peninsula, where it diverges offshore at Daly City near Mussel Rock. This is the approximate location of the epicenter of the 1906 San Francisco earthquake. The Hayward fault is about 74 mi long, situated mainly along the western base of the hills on the east side of San Francisco Bay. Both of these faults are considered major Northern California earthquake faults which may experience rupture at any time. The USGS estimates that an earthquake greater than magnitude 6.7 has a 72 percent chance of occurring in the Bay Area within the next 30 years. The Hayward fault is the most likely to produce a large earthquake with a 28% chance within the next 30 years. Reducing the reliance on natural gas appliances in homes will decrease the risk of fires when gas lines rupture and break or gas appliances topple in earthquakes. Restoring full natural gas service following a major earthquake is expected to take up to six months, compared to about a week for electricity.
3. Topographic: The City of Alameda is a low-lying island in the San Francisco Bay, resulting in high groundwater table, particularly during winter storms. Also, the City is located in an area that is relatively high liquefaction potential given its proximity to the Bay and significant proportion of filled land. Liquefaction can damage gas pipelines and cause ruptures and fires. The aforementioned conditions within the City create hazardous conditions for which departure from California Building Standards Code is warranted.
4. Compliance with California Assembly Bill 306: The changes and modifications to the 2025 California Fire Code are substantially equivalent to those previously adopted by the City of Alameda under the 2022 Codes adoption and in effect as of January 1, 2023. The proposed changes to the 2025 California Building, Residential, Plumbing, and Property Maintenance Codes address administrative procedures and are being adopted during the intervening period in accordance with Section 18942 of the California Health and Safety Code. These amendments aim to streamline internal processes related to code enforcement, permit issuance, plan review, inspections, and the maintenance of safe, habitable housing. Additionally, the ordinance promotes public safety by requiring the installation of earthquake shutoff valves, as outlined in Section 13-6.3 - Modifications, Amendments, and Deletions to the California Plumbing Code.
SECTION 2: ENVIRONMENTAL DETERMINATION. The City Council finds adoption of this Ordinance not a project under the California Environmental Quality Act pursuant to CEQA Guidelines Section 13578, and as a separate and independent basis, adoption of these local code amendments is exempt under CEQA Guidelines section 15061(b)(3) because it can be shown with certainty that this action will not have any significant environmental impact.

Notwithstanding any provisions of the California Fire Code, California Building Standards Code, State Housing Law or other codes adopted by any Chapter in Article VIII of the Municipal Code to the contrary, the following local amendments shall apply.
a. California Fire Code, 2025 Edition, Section 1103.8.5.1 is amended to read as follows:
Additions to Existing R-3 Occupancies. Notwithstanding the provisions of the California Residential Code, additions to R-3 occupancies performed within a 5-year cumulative period shall be required to provide an automatic fire extinguishing system (AFES) throughout the entire building if the proposed project includes the addition of 50% percent or more of the structure’s floor area for purposes other than damage repair or reinforcement as defined in California Existing Building Code Section 202. For clarification, an addition shall be defined as the act of increasing the residence’s square footage and does not include the conversion of existing non-conditioned, non-habitable space into habitable space. Additionally, for purposes of floor area calculations, the conversion of Group U (attached private garages, basements or similar) occupancies shall not be included in the floor area calculation.
b. Section 108 is amended to add the following new section:
New section 108.1.1- Fees for other services and excessive false alarm responses. Fees listed in the Fire Department section of the City of Alameda’s Master Fee Schedule-inclusive of fees for permits, inspections, excessive false alarm responses, and all other listed fees-shall be levied against and paid by the owner of the property. All fees shall be based on the actual cost of the service provided. A false alarm response occurs when the Fire Department responds to a false alarm or nuisance alarm, as defined by the Fire Code. False alarm responses impose substantial costs on the City of Alameda. The Fire Chief or the Fire Chief’s designee is therefore authorized to impose fees for excessive false alarm responses (“False Alarm Fees”) based on the Master Fee Schedule. False Alarm Fees shall be imposed starting with the second false alarm response and each subsequent false alarm response made to a property during the same calendar year. The Fire Chief or the Fire Chief’s designee shall issue a monthly invoice for all unpaid fees accrued during the prior month and all prior periods. Such invoices shall be due and payable within thirty days of the billing date. All remedies for unpaid fees shall be cumulative, and the use of one or more remedies by the City shall not bar the use of any other remedy for the purpose of enforcing the provisions of this Chapter. The amount of any fee shall be deemed a debt to the City. An action may be commenced in the name of the City in any court of competent jurisdiction for the amount of any delinquent debt thirty days after it becomes due and payable. Payment of any fee shall not prohibit criminal prosecution for the violation of any of the provisions of this Chapter.
SECTION 5. Severability. If any provision of this Ordinance is held by a court of competent jurisdiction to be invalid, this invalidity shall not affect other provisions of this Ordinance that can be given effect without the invalid provision and therefore the provisions of this Ordinance are severable.
