Reply to comment by buildyourown in Parking in Unfinished Basement by DirtyScoobie

Thank you for your reply! So, to be sure I understand - when you say "They require a fire wall between any space with a roll up door. Or, you can have a garage door into your basement." what do you mean? The garage door of the house goes straight from the outside into the basement, although there is a wood frame with drywall separating the garage from the basement. I still kind of think of the garage as part of the basement despite the basic wall.

At least 1/2in drywall with filled cracks all mudded and gaps filled. Foam or firecaulk applied where any plumbing or wires pass through the drywall.

Doors must be solid (20min fire rated)

All havc duct must be metal.

Edit: passage door from garage to the reast of the house should be 20 fire rated, and typically you want self closing hinges. (The hinges code has come and gone and come back again last i saw. It keeps out car fumes.)

Garage ceilings require 2 layers of 5/8" if there is a living space above.

Not a bad idea, but not required from what i have seen in my state (idaho has lower standards generally, so im not surprised.)

I have never seen double layers of drywall.

I used double layers on my HVAC air handler closet along with an insulated steel door for noise abatement, and doubled the sheetrock on the bathroom walls as well for the same reason, along with insulating both sets of interior walls. Very quiet now, it was worth it.

A sheetrock wall can be a fire barrier if it's made properly. But you want to verify that it functions as such, both for insurance but also because you don't want to kill yourself/family.
