Twain Harte sits in a State Responsibility Area, so California Public Resources Code 4291 requires homeowners to maintain 100 feet of defensible space around every structure. Cal Fire inspectors enforce annually.
California Public Resources Code 4291 mandates two zones around homes in SRA wildfire territory, which covers nearly all of Twain Harte. Zone 1 (0-30 feet) requires lean, clean, green vegetation with no dead material, while Zone 2 (30-100 feet) needs reduced fuels with horizontal and vertical spacing between shrubs and trees. After Rim Fire 2013 and Donnell Fire 2018, Cal Fire stepped up Tuolumne County inspections. Tuolumne County enforces locally through Title 5 environmental nuisance abatement when owners ignore Cal Fire warnings.
Cal Fire issues warning notices first; uncorrected violations can lead to abatement liens and fines escalating with repeat noncompliance.
