Why Are Fire-Rated Pot Lights Required in a Secondary Suite?

Fire-rated pot lights help maintain the fire separation between a secondary suite and the rest of the home. When you cut holes in a fire-rated ceiling to install standard pot lights, you can compromise the ceiling's ability to slow the spread of fire and smoke.

Fire-rated recessed lights are designed and tested to restore the fire-resistance rating of the ceiling assembly. In the event of a fire, they help:

• Slow the spread of flames between floors

• Reduce the movement of smoke and hot gases

• Maintain the integrity of the required fire separation

• Improve occupant safety and evacuation time

In many jurisdictions, including parts of Ontario, building code requirements for secondary suites often include a fire-rated separation between the suite and the principal dwelling. Using approved fire-rated pot lights is one way to comply with those requirements when installing recessed lighting.

Always verify the specific requirements with your local building department, as code requirements can vary depending on the home's construction and the municipality.
