Bristol, CT Fire Regulations: Smoke Detectors (2026)

Sec. 12-42(a) splits the smoke detector mandate by building size. Every single-family rental and every unit in a building with two or more dwelling units must have at least one smoke detector, permanently wired to a standard one-hundred-twenty-volt AC supply or run on a self-contained battery rated for at least one year of life. Buildings with two or more units also need a smoke detector at the head of every stairway leading to an occupied area, and every detector has to sit on the main sleeping level where it can monitor all the sleeping rooms, positioned to the satisfaction of the fire marshal and the Director of Health.

Sec. 12-42(b) spells out what counts as noncompliance even for a properly installed unit: a detector wired to a switch that can be turned off, one disabled by battery failure, or one that cannot give its warning for any other reason all fail the section. Sec. 12-42(c) declares a violation an immediate hazard to the health, safety, and welfare of the occupants and the public, which matters because Sec. 12-140 lets the Director of Health act on an immediate hazard without waiting for a hearing or appeal, ordering the owner or occupant to fix it on the spot.

Chapter 12 sits on the citation-enforcement list under Sec. 23-2, and the Sec. 12-135 fine schedule of fifteen to ninety dollars per offense, capped at six hundred dollars a day and nine thousand dollars total, applies to a Sec. 12-42 violation just like any other Housing Code offense.
