Is there a code for the minimum width of a closet door? I've always assumed it was 24 inches. Or is it determined by the square footage of the closet?

I have a hall closet with a 12" door. Not sure there are code requirements for a closet, but could be wrong. You need a location for code questions. – JPhi1618 Jul 30 '19 at 19:57
The Code only stipulates the size of one door in a residence. It requires one egress door that is (1) 32” clear opening with the door in the 90 degree position (which requires a 36” wide door), (2) located at a exterior entrance into the residence opening into a public way or open side yard that opens to a public way, and (3) cannot open into a garage or carport, (4) and shall be a minimum of 78” high measured from top of threshold to bottom of stop, (5) and must be side hinged...no sliding doors allowed. (See 2017 ICC R311.1 and R311.2.)
The only other requirement is for sleeping room egress windows, but that’s not your question.
