I have a garage that I wanting to turn into living space. There are 2 steps down from the house into the garage. The house joists are 2x8. What I want to do is tie into the house joists and frame a floor over the garage.
When I do this, there will be appox 7 inches between the bottom of the joists and the concrete.
I am planning on venting the space.
I am wondering if this is code to do this since there is not enough space for a man to crawl in. So technically its a crawlspace that is uncrawlable.
Code says you must have 18 inches of clearance.
Is this situation considered differently than a regular crawlspace?
That would need to be discussed with your local building inspector.
I my area if it's less then 18" I have to just use pressure treated wood.
I've done some with engineered floor joist.
Post some pictures of the outside of the garage.
One big deal is how the area where the overhead door is now.
In most cases the right way to do it would be to make it look there was never a door there in the first place.
Get rid of the old apron, build a stem wall so water will not get in under the wall.
Remove all the siding on that wall and reinstall it so there no sign of the old design.
