Stamford, CT Fire Regulations: Smoke Detectors (2026)

Article II of Chapter 70 (§§ 70-10 through 70-20) applies to all dwellings in the city, defined to exclude hotels, motels and other short-term commercial lodging. Section 70-12 puts installation squarely on the owner of every new or existing occupied dwelling: detectors must be ANSI- or UL-certified, or of a technology the State Fire Marshal has approved, and combination smoke/CO units are allowed. Section 70-13 sets the placement rules: a combination smoke/CO detector on the ceiling or wall outside each sleeping area, a smoke detector in every room used for sleeping, and a smoke detector on every story including basements (crawl spaces and uninhabitable attics are exempt); a split-level unit without a door between levels can rely on one detector on the upper level if the lower level is under a full story down.

Section 70-14 requires new construction and any dwelling with a building permit to meet the State Building and Fire Codes; dwellings permitted before October 1, 1978 are only 'preferred' to be hardwired with battery backup and may instead run on battery power alone. Under § 70-15, the owner must confirm working detectors are in place at every change of occupant from a sale, lease or sublease. Section 70-16 requires a detector with a visual alarm for a deaf or hearing-impaired occupant. After installation, § 70-17 shifts day-to-day maintenance, including battery replacement, to the occupant, and bars anyone from disabling a unit. with the owner's or occupant's consent, though a written compliance statement from the owner can waive the inspection entirely.
