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

Garage attached to a living room/kitchen area w/door that opens (20 minute or solid core). Stairs go from lower floor to upper floor bedroom area. Entire upper floor is considered the bedroom above. No door on bedroom.

Is this "direct" opening, or does the downstairs room constitue a break or intervention?

Egress is down the stairs, through the living room (only room on the lower floor, this place is small) and out another door, other than through the garage.

Thoughts.

I have seen it enforced a certain way but i am not sure i agree.

Thanks.

Time to re-up my sawhorsey membership too. Will do this weekend.

Hope everyone is doing well.
 
I have always applied it as having a room between the bedroom and the garage with (2) doors.
 
This does not appear to be a violation to me.

As you said the door opens into the living room/ kitchen area.

Although there is no door between the living room/kitchen and the upstairs bedroom,

the garage door does not open directly into the sleeping room.

No where do we have a definition that a room must have a door to be a "room."

It is a matter than needs to be evaluated on a case-by-case basis based on the AHJ's judgement.

The biggest issue for 302.5.1 is to prevent carbon monoxide from entering the bedroom. With direct communication to the upstairs "where the CO will rise to" would only exserbate the the potential for poisoning.

Carbon monoxide may have neutral buoyancy in air. Could it be more about fire than CO?
 
Does the door open "DIRECTLY" into a room used for sleeping purposes? Sounds like the answer to this question is no. Compliant design.

Going back to commentary; "Openings to sleeping rooms from garages are not allowed,since a person might not wake up in time if there was a hazard from carbon monoxide fumes or smoke from the garage." I leaned more on the side of a car running in the garage and a negative pressure created inside the house from duct leakage, but if there was a fire there is probably CO with it also.
 
If the garage is on fire, I would want a door to close while I waited on the FD for rescue...but that's just the fire guy in me.

My opinion is that this is a compliant design.
 
With no door to the bedroom at the top or bottom of the stairs, I say no way. Fire and smoke rise and the stairway could become a chimney.

I agree. The intent is to prevent smoke and CO from entering the sleeping area.
 
"Openings from a private garage directly into a room used for sleeping purposes shall not be permitted." You may not like it but the design is compliant. This code section gives little room for individual interpretation. Cite the code section that requires interior doors.
 
Let's try this. Instead of a two story with stairs it's a single story and the garage opens into a hallway. There is a bedroom off that hallway. There is no door between the hallway and the bedroom. What now?

I forgot to mention that it's a Tuesday in Phoenix AZ.

ICE,

You die!
 
"Let's try this. Instead of a two story with stairs it's a single story and the garage opens into a hallway. There is a bedroom off that hallway. There is no door between the hallway and the bedroom. What now?"

The design is compliant because the door to the garage opens into a hallway, not a sleeping room.

That's compliant. The way I've interpreted this requirement (we have the same on in Canada, so it must be a good idea if our codes agree on it) is that if I am standing in the garage and step through the door what room am I in? If the answer is not "bedroom" you have a compliant installation. If we want to take it to extremes then why would you allow it to open into a living room? People fall asleep on their living room couches all the time. We are not the safety police, we have to be reasonable.
 
Again, cite the code section requiring interior doors---to any room. I only mention this again because a long time ago it was a topic on this forum and I do not believe anyone could identify language in the IRC that required any interior doors.
