Calaveras County, CA Fire Regulations: Propane Storage (2026)

Calaveras County does not have a separate, more-lenient local propane rule; LP-gas container placement is governed by NFPA 58 (Liquefied Petroleum Gas Code), which California adopts through its fire code, with the local fire authority (CAL FIRE TCU / county fire) as the authority having jurisdiction. NFPA 58 Table 6.4.1.1 sets minimum separation distances measured from any part of the container surface to important buildings and to the line of adjoining property that can be built upon. For aboveground containers: tanks under 125 gallons water capacity have no required separation distance to a building or property line (0 feet), though other placement rules still apply; tanks 125-250 gallons and 251-500 gallons must be at least 10 feet from buildings and property lines; and tanks of 501-2,000 gallons must be at least 25 feet (reducible to 10 feet for a single ASME container of 1,200 gallons or less where it is at least 25 feet from any other LP-gas container over 125 gallons - the so-called restaurant exemption). NFPA 58 also sets relief-valve clearances: the discharge from a container relief valve and the filling connection must be kept away from building openings and sources of ignition - generally a minimum of 5 feet from exterior ignition sources, direct-vent appliance openings, and ventilation air intakes for exchange cylinders. Combustible materials should not be stored within 10 feet of a container. Because the county is high fire-hazard, keep tanks clear of vegetation and confirm exact placement with the local fire authority and your propane supplier.
