Why carbon monoxide detector installation comes up in Boston

Massachusetts requires carbon monoxide alarms in homes with fossil-fuel appliances or attached garages, and a home generally cannot be sold without a fire department certificate showing smoke and CO alarms meet state rules. Boston's triple-deckers and condos with gas or oil boilers need CO alarms on every level of each unit. Requirements depend on when the building was built or last renovated.

A licensed electrician can install hardwired, interconnected alarms that meet the rules before the Boston Fire Department's inspection. Permits come from Inspectional Services. Test alarms monthly.

  • In Massachusetts, a home generally cannot be sold or transferred without a certificate from the local fire department confirming that smoke and carbon monoxide alarms meet state requirements, and in Boston that inspection is done by the Boston Fire Department.

    Every alarm is tested to confirm one sets off all.

What moves the price in Boston

Electricians set their own prices. Massachusetts heat-pump incentives are driving a wave of electrification, and most older homes need a service upgrade before a cold-climate heat pump can be installed.
