Orlando, FL Building Safety: Fire Sprinkler Requirements (2026)

Sec. 27(c) of Orlando's Fire Prevention Code, an addition to NFPA 1 Chapter 13, mandates that 'all new residential occupancies, except detached one- and two-family dwellings, shall be protected throughout by an approved and electrically supervised automatic sprinkler system in accordance with NFPA 13, Standard for the Installation of Sprinkler Systems' (Sec. 27(c)(1)). Two building-specific exceptions soften that baseline: residential buildings up to four stories may instead use the lighter NFPA 13R standard where the Building Code does not otherwise require full NFPA 13 protection (Exception No.

1), and multi-family townhouse units separated by two-hour fire-rated firewalls may use the even lighter NFPA 13D standard written for one- and two-family dwellings (Exception No. 2). The sprinkler mandate also reaches beyond new residential construction: any new building or addition exceeding 5,000 square feet, and any existing building with a new occupancy or change of use exceeding 10,000 square feet, must be fully sprinklered under NFPA 13 (Sec. 27(c)(2)-(3)). Four further carve-outs exempt occupancies where sprinklers would increase rather than reduce the hazard, greenhouses and aircraft hangars protected under NFPA 409, buildings storing only Fire Chief-approved non-combustible material, and open-air structures where the Fire Chief finds sprinklers would not materially improve life safety.

Supervisory monitoring is required for every automatic sprinkler system under Sec. 27(b)(1), though one- and two-family systems built to NFPA 13D are exempted from that electronic-supervision requirement.
