Summary
Sacramento's local fire code amendment exempts detached single-family homes (Group R-3) from the city's general sprinkler-installation trigger, which otherwise applies to any building over 3,599 square feet. But when sprinklers are installed in a one- or two-family home or townhouse, Sacramento City Code § 15.36.050(F) requires NFPA 13D design and a full engineered submittal package.
903.2 Where required. For all occupancies except Group R-3 and detached U, an automatic sprinkler system shall be installed and equipped with an electronic monitoring system as follows: 1. In every new building where the total floor area exceeds 3,599 square feet (1097 m2)... 903.3.1.3 NFPA 13D sprinkler systems. Automatic sprinkler systems installed in one- and two-family dwellings and townhouses are permitted to be installed throughout in accordance with NFPA 13D and the City of Sacramento standards. Every submittal shall include a full set of plans including details of type of pipe and fittings, hydraulic calculations, elevation views of all potential models if site is a master planned community and any other requested data sheets.
