What is code for the fire rating for garage walls?

Monday, July 27, 2020

Any common walls between an attached garage and the house must have minimum 1/2” drywall or equivalent on the garage side of the wall. Only common walls (not perpendicular walls) must meet this requirement. If a garage is detached, but within 3-feet of the residence, any walls within 3-feet must have 1/2” drywall or equivalent.

    This is part of multiple requirements for “Dwelling-Garage Separation” for an attached garage in the International Residential Code (IRC) and the Residential Edition of the Florida Building Code (FBC). While not called a “fire rating,” the specs are intended to create a fire barrier to reduce the spread of a fire from an attached garage to the living area of a home. To learn about the other garage fire separation requirements, go to our blog post What are the code requirements for fire separation between an attached garage and the house?
