Full Breakdown
Nashua's Housing Standards code, § 182-41, requires every dwelling unit to have a listed smoke detection/alarm device on each level, positioned near the bedrooms, with an additional device at the foot of any basement or cellar stairway leading into the unit. Units must be powered by the building's electrical service, and a permit from the Code Enforcement Department is required before that wiring work begins. Detectors and their equipment must stay in operating condition at all times. Buildings with two or more dwelling units must also wire smoke detectors into common corridors and stairways at each level. Battery-only units installed before July 1, 1984 can remain in service until they need replacing.
Violations & Fines
Violations of Chapter 182, including the smoke detector rules, are punished as provided in Nashua City Code § 1-12; each day a violation continues after due notice is a separate offense.
