Propane is the primary heating fuel for many Twain Harte cabins and homes. The California Fire Code and Cal Fire rules require setbacks, anchoring, and a 10-foot clearance of vegetation around tanks to reduce wildfire ignition risk.
Under the California Fire Code adopted by Tuolumne County, propane tanks must be set back from buildings, property lines, and ignition sources based on tank size: typically 10 feet from buildings for residential 250-500 gallon tanks. A 10-foot zone of cleared, non-combustible space around the tank is required to reduce wildfire ignition risk. Tanks must be on stable, non-combustible bases and protected from vehicle impact. Snow loads in this Sierra community require regular checks of regulators and lines. Installation and exchange must use a state-licensed propane contractor.
Code-enforcement notice; Cal Fire defensible-space citation tied to PRC 4291; propane company refusal to refill non-compliant tanks.
