Instead of of having nothing under the platform of a U shaped stair, I decided to enclose it, creating a space with 4'-11" ceiling height. It's really just a storage space. I want to add a access door so that the client can store stuff under the stair. I get that per R302.7 the walls and ceiling need type x gyp on it but what about the access door? Does it have to be a 20 min rated fire separation door with self closing device? This seems like overkill but I can't find anything about doors that lead to the accessible space under stairs. Help please.
