Full Breakdown
2 to the 2025 California Fire Code as adopted by the City of Sonoma, capping the aggregate water capacity of any one liquefied petroleum gas installation at 2,000 gallons within the limits established by law for heavily populated or congested areas, as set by applicable land-use and zoning standards. The fire code official can reduce that 2,000-gallon ceiling further after evaluating site-specific factors: topography, the nature of the occupancy, how close the containers sit to buildings, the capacity of the proposed LP-gas containers, the degree of fire protection already in place, and the responding fire department's capabilities.
5, Anchoring, which requires an approved anchoring system on every permanently installed propane or LPG gas container in the city, regardless of size. Read together, the two subsections mean a Sonoma property owner installing a fixed propane tank, whether for a residence, winery, or business, faces both a volume cap in congested or populated areas and a mandatory anchoring standard everywhere the container is permanently installed. 3, showing a broader local pattern of tightening fixed fuel-storage rules beyond the base state fire code. 010(A)(4) sets infraction fines of $100 for a first offense, $500 for a second, and $1,000 for a third violation of the same section within a year.
Violations & Fines
Exceeding the 2,000-gallon aggregate LP-gas capacity limit in a restricted area, or installing a permanent propane container without an approved anchoring system, violates SMC § 14.10.040 subsections 6104.2 and 6107.5. Both are Chapter 14.10 SMC infractions under SMC § 1.12.010(A)(4): $100 for a first offense, $500 for a second violation of the same section within a year, and $1,000 for a third.
