I would like to install an entry door in a wall that currently separates my garage and the hallway of my house. My concern is how do I find out how to install the door so that it meets all building requirements? I don't even know where these building requirements are. I know there are building code requirements relating to fire-rating, clearances, and steps from the garage floor to the door (my house has raised foundation).

 

Call your local Building Inspector / or contact your county or city permit department.

 

Which one is it? local building inspector, county department, or city department?

 

Yeah sorry but I don't know where you live or how things work there. I can't possibly know if you would call your county or city. If you can find a number for your Building Inspector, start there.

 

Since you're in California I will assume you need a fire rated door with self-closing hinges. This is typical in any city I've worked in.
You can go to the local building department (usually at city hall), take a number, and they will answer your question quickly.
There are no variations that I know of, the door must have self-closing hinges.

 

I like that. But not here in New York. At least not in my area. Never heard that the height or number of stairs was a concern or code!
