Full Breakdown

In new multiple dwellings, smoke detectors must be directly wired to the lighting circuit (no wall switch; no cord connections) and must be audible in adjoining sleeping spaces with doors closed. Existing multiple dwellings may use battery-operated or plug-in detectors but may not be controlled by a wall switch; plug-in outlets must have plug-restrainer devices. New and existing one- and two-family dwellings must have a detector protecting each sleeping area and one at the head of each stairway leading to an occupied area.

Violations & Fines

The City of Buffalo is not liable for damages due to non-compliance. Violations are enforceable under Chapter 103 (building code) and general Code penalty provisions.
