Conn. Gen. Stat. § 29 § 29-315b
Temporary installation of smoke and carbon monoxide detectors and warning equipment in one and two-family residential buildings during interior alterations or addition.
Operative Text
Whenever any private residential dwelling designed to be occupied by one or two families is occupied during interior alterations or additions requiring a building permit, the temporary installation of battery-operated smoke detection and warning equipment and, if there is a fuel-burning appliance, fireplace or attached garage present, battery-operated carbon monoxide detection and warning equipment shall be required in the vicinity of, and during the performance of, such alterations or additions. Such equipment shall be of a type or technology that is tested and certified pursuant to standards issued by the American National Standards Institute or Underwriters Laboratories. Such equipment may combine smoke and carbon monoxide detection technology into a single device.
Under Conn. Gen. Stat. § 29-315b, when a one- or two-family home is occupied while interior alterations or additions requiring a building permit are underway, battery-operated smoke detection equipment must be temporarily installed in the work area. If the home has a fuel-burning appliance, fireplace, or attached garage, battery-operated carbon monoxide detection equipment is also required during that same period. All such equipment must meet standards set by the American National Standards Institute or Underwriters Laboratories, and combination smoke/CO devices are permitted.
Plain English — not legal advice.
Operators of one- and two-family residential properties should ensure that any permitted interior renovation project where occupants remain in the home is equipped with compliant battery-operated smoke detectors in the work area, as required by Conn. Gen. Stat. § 29-315b. When the property includes a fuel-burning appliance, fireplace, or attached garage, a battery-operated carbon monoxide detector meeting ANSI or UL certification standards must also be in place for the duration of the work. Keeping documentation of the equipment's certification and placement is a practice commonly associated with maintaining compliance during the permit process.

Conn. Gen. Stat. § 29-315b gives occupants of one- and two-family homes a right to have certified, battery-operated smoke detection equipment—and carbon monoxide detection equipment where applicable—installed near any permitted interior construction work while they continue living in the home. If this equipment is absent during active alterations or additions, tenants may raise the issue with the local building department, which oversees permit compliance. Tenant-rights organizations can help residents understand how this provision interacts with other habitability protections.
