Bedroom Door leading to garage

Can a bedrooom(with proper window size)in a basement be considered legal if there is a door leading to the garage which is properly fire proofed?

In one word… no



In two words: absolutely not.

In three words; unsafe to do.

next. :slight_smile: :wink:

Four words, all of which gerry understands: Not on your nelly

What’s a basement?

And why not?

Nope, bedrooms should NOT open into a garage. Has nothing to do with the basement, just the bedroom to the garage.

Openings from a private garage directly into a room used for sleeping purposes shall not be permitted.

If you really needed a bedroom in that area, a simple solution would be to build an ante-room (a small entry room) between the new bedroom and the garage. This could be a small closet-sized space, with a fire-rated, self-closing door on the garage side, for firewall compliance. In this way, you could have your attached garage, your added bedroom, and no direct access between the two. Check with your local building department to see if they would accept this approach.

Mr. Valley quotes from R309.1 of the International Residential Code. I’m looking at the 2003 edition, but I can’t imagine that this provision would change in any later edition.

This clause further staes that “Other openings betweenthe garage and residence shall be equipped with solid wood doors not less than 1 3/8 inches in thickness, solid or honeycombed steel doors not less than 1 3/8 inches in thickness, or 20-minute fire-rated doors.”

Here’s the information from the latest edition. I thought I would throw in a few extras, I hope that some of you find this information to be useful.

2006 International Residential Code for One and Two Family Dwellings

R309.1 Opening protection.

Frank, thanks for posting this.
My question is when did this code become effective?
I inspected a 1985 home in a PUD which most of them are this way.


Code dates do not matter IMO.

It’s simply a safety issue…

The requirement dates back to the 50’s. Perhaps even earlier.

Should you run into a used house salesman who wants to argue that a violation like this should be ignored since the house was built before the rule was implemented…explain that you would be happy to apply the 1950 standard with the written guarantee from the broker that all vehicles entering the garage will also be pre-1950, that no pesticides, weed killers or other household poisons developed after 1950 will be stored in the garage…as well as pre-1950 manufactured petroleum products, paint products and yard/household tools.

Thanks Jeff and James.

You ask a “Duh” question, you get a “Duh” answer…

Had one yesterday on a 1985 ranch where they put a garage door in the basement next to the driveway (they said it was put in to make bringing furniture in easier;)). The basement was wide open with suspended ceiling tiles and an open stairway with no door into the house.

David, I am joking with you. The condition is obviously unsafe. My question was more directed to what the others responded, i.e. when. I wanted a specific answer, if possible, so I could speak to all with authority, instead, “I don’t know, but I know it’s not safe and not permitted” etc.
Have a happy IR day.

1927 Section 1505 “Under no circumstances shall a private garage have any openings into a living or sleeping room.”
