Doors – Closet door minimums

closetdoors

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?

Best Answer

The Code only stipulates the size of one door in a residence. It requires one egress door that...

  • has a 32” clear opening with the door in the 90 degree position (which requires a 36” wide door)
  • is located at a exterior entrance into the residence opening into a public way or open side yard that opens to a public way
  • does not open into a garage or carport
  • is a minimum of 78” high measured from top of threshold to bottom of stop
  • is 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.
