Full Breakdown

Texas Local Government Code 233.153 prohibits counties from requiring fire sprinkler systems in newly constructed one or two family dwellings, even when adopting later editions of the International Residential Code. Builders may install sprinklers voluntarily, and homeowner insurance carriers often offer premium discounts. Multifamily dwellings (R-2 occupancy) and commercial buildings must comply with NFPA 13 sprinkler requirements per the IBC and IFC adopted countywide. Bexar County permits review through the Public Works permit office verifies sprinkler plans. Existing structures retrofitted with sprinklers must follow Texas State Fire Marshal rules.
