The 7 and 7 rule for attics is building code and real estate guideline that defines when an attic can be considered habitable living space rather than just storage. Rule states that to be considered habitable attic, at least 50 percent of attic area must have ceiling height of 7 feet or more, and that area must be at least 7 feet wide and 7 feet long in minimum dimensions, with total habitable area at least 70 square feet. This rule is derived from International Residential Code requirements for habitable rooms, which require 7 feet minimum ceiling height over at least half of room area. The 7 and 7 rule ensures attic has enough usable space with adequate headroom for living. It also relates to egress, as habitable attics need proper staircase and emergency escape window. If attic does not meet 7 and 7 rule, it is classified as storage attic not counted as bedroom or living space for appraisal and code purposes.
