Floor plans are an important part of real estate appraisals to show a clear overview and layout of the property. As of April 1, 2022, Fannie Mae requires appraisers to measure subject property improvements using ANSI Standard Z765-2021. Although it is one of the easier measurement standards, it is still a fairly challenging standard to align to – with specific considerations such as ceiling height, below-grade spaces, stairs, and more. Providing ANSI-aligned floor plans with GLA measurements and interior walls is essential for 1004 (Desktop) Appraisals, this industry change will be effective March 19th, 2022.
