24 CFR Part 100—Fair Housing Accessibility Guidelines

(2) Within individual dwelling units, doors intended for user passage through the unit which have a clear opening of at least 32 inches nominal width when the door is open 90 degrees, measured between the face of the door and the stop, would meet this requirement. (See Fig. 1 (a), (b), and (c).) Openings more than 24 inches in depth are not considered doorways. (See Fig. 1(d).)

Note

A 34-inch door, hung in the standard manner, provides an acceptable nominal 32-inch clear opening. This door can be adapted to provide a wider opening by using offset hinges, by removing lower portions of the door stop, or both.
Pocket or sliding doors are acceptable doors in covered dwelling units and have the added advantage of not impinging on clear floor space in small rooms.

The nominal 32-inch clear opening provided by a standard six-foot sliding patio door assembly is acceptable.

(a) Hinged Door

(b) Folding Door

(c) Sliding Door
