Are recessed fixtures permitted in walls or partitions that require a fire-resistance rating?

Recessed fixtures can be permitted in walls or partitions that require a fire-resistance rating if they are specifically designed and tested to maintain the integrity of the fire-resistance rated assembly. This means that these fixtures should meet certain standards that ensure they do not compromise the performance of the wall or partition in terms of fire resistance.

When recessed fixtures are installed, they should be evaluated to ensure that they maintain the fire-resistance rating of the wall or partition. This is often done through the use of fire-rated boxes or enclosures that do not reduce the safety margins of the wall assembly. Compliance with local building codes and standards, such as those from the International Building Code (IBC), is essential in these scenarios to ensure safety and adherence to fire protection principles.

By ensuring that recessed fixtures meet the appropriate fire safety standards, it allows for flexibility in design while still prioritizing safety and compliance with fire codes.
