Petaluma FAQ
Do propane tanks have to be strapped down in Sonoma County?
Yes. The locally amended fire code requires an approved seismic anchoring system on every permanently installed propane or LPG container, using bolting, strapping, or anchoring methods described in Permit Sonoma's LPG Tank Hold Downs bulletin.
How large can a propane installation be in unincorporated Sonoma County?
Where land-use and zoning standards restrict LP-gas storage, the aggregate capacity of any one installation may not exceed 2,000 gallons water capacity under California Fire Code Section 6104.2 as locally amended.
What materials are acceptable for LPG tank hold-downs?
Permit Sonoma's bulletin specifies quarter-inch galvanized or stainless cable, or 1.25 x .031 stainless steel strapping with 4,750 pounds minimum tensile strength; half-inch bolts or eye bolts must be set in concrete or treated wood.
Sonoma FAQ
Can I install a 500-gallon propane tank at my house in Sonoma?
Yes, but it must meet California Fire Code Chapter 61 setbacks – at least 10 feet from any building opening and 10 feet from the property line – and requires a fire department operational permit from the Sonoma Valley Fire District Fire Marshal because it exceeds the 125-gallon threshold. NFPA 58 installation standards also apply.
Can I store a small propane cylinder for my BBQ indoors?
No. California Fire Code §6103.2 prohibits LP-gas containers inside buildings (including garages, sheds, basements, and pits) except for very small containers in approved conditions. Store BBQ propane cylinders outdoors away from heat sources, ignition, and building openings, and never in a basement or below-grade space.
