Summary
Santa Fe's fire code sets sprinkler-system water-supply and fire-flow standards for one- and two-family homes under Appendix B of the 2021 International Fire Code. The Fire Marshal may accept an NFPA 13, 13R or 13D sprinkler system, monitored alarms, or NFPA 1142 water tanks in place of full fire flow, and additions of 500 square feet or less to an existing home are exempt from adding sprinklers.
B105.3 Water supply for buildings equipped with an automatic sprinkler system. For buildings equipped with an approved automatic sprinkler system, the water supply shall be capable of providing the greater of: 1. The automatic sprinkler system demand, including hose stream allowance. 2. The required fire flow. B105.4 Life safety equipment in lieu of fire flow. In lieu of fire flow, the Fire Marshal may approve the use of a fire sprinkler system complying with NFPA 13, NFPA 13R, NFPA 13D, Type VA construction and/or monitored fire alarms system. and/or water storage tanks complying with NFPA 1142 for one- or two- family dwellings, R-3, or R-4. Exception: Automatic fire sprinkler systems shall not be required for existing one-family or two-family dwellings that do not meet fire flow, that are not already provided with an automatic sprinkler system where an addition to the existing structure's total roofed square feet does not exceed 500 square feet.
Full Breakdown
1 SFCC 1987 adopts the 2021 International Fire Code, as amended, as 'the fire code of the city of Santa Fe,' with amendments recorded in Exhibit A at the end of Chapter XII. Item 14 of those amendments rewrites Appendix B, Fire-Flow Requirements for Buildings. 2 covers all other buildings. 3 requires that where a building carries an approved automatic sprinkler system, the water supply must be capable of delivering whichever is greater: the sprinkler system's own demand (including hose stream allowance) or the code's required fire flow.
4 gives the Fire Marshal discretion to accept life-safety equipment in place of full fire flow for one- and two-family dwellings and R-3/R-4 buildings: an NFPA 13, 13R or 13D sprinkler system, Type VA construction, a monitored fire alarm system, or NFPA 1142-compliant water storage tanks. The same subsection then carves out existing one- and two-family homes that do not meet the fire-flow standard and that lack a sprinkler system already: they are not required to add automatic sprinklers so long as any addition does not push the structure's total roofed area past 500 square feet. 1(C).
Violations & Fines
Chapter 12's amendments don't set a stand-alone sprinkler fine; noncompliance is enforced the same way as any fire code violation, through the fire prevention bureau's plan review and inspection process under Sections 12-2.2 and 12-2.3, and a building cannot receive a certificate of occupancy until required fire-flow or sprinkler substitutions are verified.
