Smoke Detector Regulations in MA

Selling

• Massachusetts law requires one- or two-family homes to have have approved smoke detectors installed at construction or when remodeling. Residents must also install approved smoke alarms before selling the home. The exact type of smoke detector required will depend on the age of the home.

Types

• Homes built before 1975 should have a dual-type smoke detector. These detectors have both photoelectric and ionization capabilities. Photoelectric smoke detectors use light to detect smoke, while ionization types use radiation. The type of smoke detector required for homes built after 1975 will depend on the state requirements in effect at the time of construction.

Verification

• Massachusetts homeowners should make sure they comply with state law by having their smoke detectors inspected by a local fire department. The fire inspector issues certificates to those who meet local requirements. Many mortgage companies throughout the state require this certificate before the loan can be processed. Landlords should have this certificate before seeking tenants.
