ANSI Z765 Square Footage Method

Frequently asked questions on square footage method for calculating

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 measurement 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.

Fannie Mae requires the Square Footage – Method for Calculating: ANSI Z765-2021 to be used by appraisers to determine gross living area (GLA) and non-GLA areas for properties requiring interior and exterior inspections.
