12' Doors with 12' Eaves

[HGFireHazard]

Is it possible?

I have a neighbor that's proposing a 30'x50' steel structure, 4/12 roof pitch. On the 30' side he says he's putting 2, 12'x12' roll up doors. I didn't think there would be room for such large doors but I don't know enough to say. I'm part of an approving body in an HOA and our maximum eave height allowed is 12'. If it's reasonably possible then great, but my concern is it realistically isn't and instead he's planning a 14' eave height. Any guidance?

I don't think there is a problem with having doors that tall on the gable end of the building, but just have him provide a drawing to illustrate what he has planned.

Any guidance?

If I was on the board and he could get a roll up door in with a 12' eve, I'd approve the structure. The engineering isn't purview of the HOA, compliance of the eve is... Agree that drawings might solve it.

That being said, if you're trying to keep the home owner out of a jam, a 12' door usually requires a 14' eve. Why? Because the "roll up" section of the door sits above the eve, so you need garage height + 16" or so for the "roll" of the garage door and some additional space.

A door that is centered on the building (gable end) are not as impacted by the eve because they're limited by the roof height.

Thanks to both of you for the feedback. I'm not one of the crazy ones, I want everyone to have everything possible under the rules. If it can fit in the eave I don't care how tall the doors are. What you said is basically it, I want to keep the owner out of a jam. He provided some hand drawings but not schematics but maybe we can ask for such.

why such a rule?
what is the exact rule verbiage please?

Yes he can get a door to work.

It could be a factor of how his roof rafters or trusses are designed, too. There could be additional headroom included to accommodate the taller door.

I ended up talking to the person directly. It turns out they won't be 12' tall because they won't fit, but he ordered 12' doors and is just going to have them be as tall as they can be based on fitment. He said likely they will be between 10-11' tall.

It's just a straight 4/12 roof.

I appreciate the responses!

Thanks for not being one of the crazy ones... Yea, roll up doors can go at any height. You might have saved him a few bucks otherwise.

I did a similar structure. A steel building with 12 foot eve height and I used 10 foot roll up doors. The metal building installer side that typically the doors when installed on the side wall like mine are at least 2 foot short of the eves height. That way they struck with standard size doors. After the building was finished I would say that the doors could have been roughly 11 foot based on the clearance above the door and how the structure was fabricated.

Here is a previous thread. There are others as well.

I have a door to full ceiling height on the gable end but it is a swing out type not roll up. The building dept. had me place 2 trusses at the end of the building with 3/4" ply sandwiched between them. A bit of an overkill for a 12' wide door on a 26' wide wall but everyone came out happy.
