FANNIE MAE ADOPTS APPRAISAL STANDARD FOR SQUARE FOOTAGEAppraisers will be required to use a new Measuring Standard for measuring, calculating, and reporting gross living area (GLA) and non-GLA areas of subject properties for appraisals requiring interior and exterior inspections with effective dates of April 1, 2022 or later on loans sold to Fannie Mae. Historically, Fannie Mae’s Selling Guide has not required the use of a specific measurement standard. This policy update will standardize the method used to measure, calculate, and report GLA and non-GLA areas of subject properties. All footprint sketches and floor plans must be computer-generated (not hand-drawn), indicate all the dimensions needed to calculate the GLA and other required areas such as garage and basement, and show the calculations to demonstrate how the estimate for gross living area was derived.
