California Residential Code requires automatic fire sprinklers in new one and two-family dwellings and townhouses, and Sacramento applies the rule citywide through Title 15 with additional standards for substantial remodels and ADUs.
Since 2011 the California Residential Code section R313 has required automatic fire sprinkler systems in newly built one and two-family dwellings and townhouses. Sacramento adopts and enforces this requirement under Sacramento City Code Title 15 through the Building Division, with plan review and acceptance testing by the Sacramento Fire Department. Sprinklers are also commonly required when a remodel or addition is large enough to constitute a new dwelling or when an accessory dwelling unit triggers thresholds in the local administrative provisions. Some narrow exceptions and alternative materials may be allowed with engineering and approval.
Building permits will not be finalized without an approved sprinkler system where required. Bypassing the requirement can lead to permit revocation, mandatory retrofit, occupancy denial, and code enforcement penalties.
