Square Footage - Method for Calculating: ANSI Z765-2003
Available for purchase from the NAHB Research Center Bookstore, this voluntary standard for measuring square footage in single-family detached and attached homes, developed by an American National Standards Committee, is the first national standard to reconcile differences in current methods for determining square footage. The standard involves the calculation and reporting of above-grade square footage and below-grade square footage in single-family houses. It is not applicable to apartment/multifamily buildings and does not cover room dimensions. The document is available in both hardcopy and PDF formats.
