2.2. Smoke Alarms

This inspection protocol specifies where smoke detectors should be located in dwelling units. Smoke detectors/alarms are required in dwelling units in the following locations:

• Inside each sleeping room (e.g., bedroom); and,
• Outside each sleeping room; and,
• Within 21 Feet of All Bedroom Doors; and,
• On every level of a dwelling unit, and
  

As of June 11,2024, these two deficiencies were now stated to be a recommendation only and are not a “requirement”. See the update notice here on our website.

• “Not” within 10 feet of a cooking appliance;
• “Not” within Three feet of Ceiling Fans, Air Ducts, Exterior Doors, or Windows
  

Smoke detectors do not have to be hard-wired, and there are no design requirements for the type of alarm used at a property. However, there are specifications as to the location of each smoke alarm on a wall or ceiling:

• If mounted on the ceiling, it must be more than 4 inches from the wall.
• It cannot be closer than 4 inches or more than 12 inches from the ceiling if mounted on the wall.
• Smoke alarms should not be installed within 36” of windows, exterior doors, or ducts where drafts might interfere with their operation.
• Smoke alarms should not be painted or have stickers or other decorations present.
  

During an inspection, each smoke alarm should be physically tested to ensure the device tests as intended. If the property cannot demonstrate that the device works properly, it should be cited as inoperable.

As of December 29, 2024, all smoke detectors which are solely battery-operated will have to have sealed, tamper-proof batteries. It will not be an NSPIRE deficiency until that time.
