Where should attic access be placed by code?
Monday, April 20, 2020
The attic access opening must be located in a “hallway or other readily accessible location” according to the International Residential Code (IRC R807). Also, the “minimum unobstructed headroom in the attic space shall be 30” at some point above the access” and the minimum rough framed access opening cannot be less than 22” wide by 30” long. So, for example, it should not be above shelving in a closet or so close to the bearing point of roof rafters or trusses that there is not enough headroom to safely get in and out of the opening without being a contortionist.
