Can I use plywood between garage and living space of my house?
Tuesday, November 24, 2020
The code requires 1/2” drywall—or a material of comparable fire resistance—for a fire separation between an attached garage and the house. Plywood is too flammable to be acceptable. But drywall is only required on the common walls with the house, and the ceiling when the attic above is continuous with the house attic. So you can use plywood, pegboard, and whatever other wallboard material you want instead of drywall on the other three walls of the garage.
And, of course, you can apply these materials over the drywall on the common walls and ceiling if you want. See our blog post What are the code requirements for fire separation between an attached garage and the house? for more details.
