Greenburgh, NY Building Safety: Fire Sprinkler Requirements (2026)

Town Code § 100-13A sets two trigger dates: any building other than a one- or two-family home built after June 8, 1977 needs an NFPA-compliant fire sprinkler system, and starting October 13, 1982 that mandate extends to one- and two-family residences as well. Under § 100-13B, before the Building Inspector issues a building permit, the builder must submit two sets of sprinkler plans signed and sealed by a New York State-licensed professional engineer, a NICET Level 3 or higher technician, or a licensed fire protection engineer.

Section 100-13C reaches existing buildings too: if a non-residential structure without a conforming sprinkler system expands its floor area by 50% or more, if alteration or repair costs exceed 50% of the building's replacement cost within any six-month span, or if the use converts to an A occupancy under the Uniform Code, the owner must submit plans under § 100-13B and install a fire sprinkler system. Section 100-13D backs this up at the finish line: no certificate of occupancy can issue for any building, structure, or portion of one required to have a sprinkler system until that system is installed, inspected, tested, and approved to NFPA standards.

Chapter 100 also cross-references this requirement in § 100-14A, tying required smoke- and heat-detection devices to the § 100-13 sprinkler standard, and in § 100-14F, which ties carbon monoxide detector requirements to the same section.
