Since 2011, the California Residential Code has required automatic fire sprinklers in all new one- and two-family homes. Twain Harte residents building new houses must install NFPA 13D residential sprinkler systems.
California Residential Code Section R313 requires automatic fire sprinklers in all newly constructed one- and two-family dwellings statewide, including Twain Harte. Tuolumne County Building Department enforces the requirement during plan check and inspection. Systems must comply with NFPA 13D, with adequate water supply, freeze protection appropriate for Sierra winters, and proper coverage of habitable rooms. Major additions and rebuilds after fire loss can trigger sprinkler retrofit. Wells and CSD water connections must demonstrate sufficient flow and pressure, sometimes requiring a tank and pump.
No certificate of occupancy without working sprinkler system; permit hold; mandatory correction at owner's cost; inspection re-fees.
