Did you know that most home owners are unaware that their garage and its systems are supposed to be able to slow the spread of a fire if one should occur in the garage?
Some examples of the living space shared wall between the home and garage should have the some of the following.
- Floor should be noncombustible material
- Door should be fire rated or solid wood door at least 1-3/8 inches thick and or solid or honeycomb-core steel door at least 1-3/8 inches thick. No openings in the door.
- The garage living space wall should be not less than 1/2-inch (12.7 mm) gypsum board applied to the garage side. Garages beneath habitable rooms shall not be less than 5/8-inch (15.9 mm) Type X gypsum board or equivalent. Walls should be taped and sealed appropriately to the local government requirements.
- Attic access should have a hatch cover made from an approved, fire-rated material. (We recommend having a home inspector investigate if your home has a garage attic access).
We recommend reaching out to your local local home inspector if you have any questions and concerns or you can call me directly at 720-660-5419.
Below is an example showing the walls that are shared living space wall in correlation to the garage walls.

Above is a great example of a new build garage wall we want to see when inspecting a home. You can clearly see the drywall is taped and sealed. Also you can clearly see the fire rated metal plate on the back of the service garage door.

The example garage in question may have some of them, none of them, and or all of these things regarding the considerations. It’s important to have a professional help determine the risk and if in need of repair/replacement.
