Code Requirements

The International Building Code Section 711.4.2 states:

“Where floor/ceiling assemblies are required to have a minimum one-hour fire resistance rating, recessed fixtures shall be installed such that the required fire resistance of the ceiling will not be reduced.”


The Uniform Building Code (UBC) in Section 710 states:

“When materials are incorporated into an otherwise fire-resistive assembly that may change the capacity for heat dissipation, fire test results or other substantiating data shall be made available to the building official to show that the required fire-resistive time period is not reduced.”
