Half-Story Square Footage Appraisal: ANSI Rules, Cape Cods, and What Counts as GLA
140+ guides covering GLA measurement, ANSI Z765, floor plan tools, appraisal requirements, and square footage rules for every property type.
What does the Learn library cover?
The Learn library has step-by-step guides on residential square footage measurement: ANSI Z765 methodology, GLA vs total square footage, county assessor records, MLS accuracy, finished basements, additions, multi-story homes, and how appraisers calculate square footage in practice.
Who are these guides for?
Real estate appraisers verifying GLA, agents preparing listings, homebuyers verifying square footage before making an offer, homeowners measuring for insurance or refinancing, and investors underwriting acquisition targets. Each guide assumes no prior appraisal training.
Where do I start if I'm new to square footage?
Begin with "How to Measure Square Footage: The Complete Guide" or "ANSI Z765 Square Footage Standard Explained." Both cover the foundations: what GLA is, how it's measured, what counts and what doesn't, and why different sources show different numbers.
How often are guides updated?
Foundational guides (ANSI Z765, GLA basics) are reviewed annually. Topical guides addressing changes in lender requirements (such as the 2022 Fannie Mae ANSI mandate) or new tool releases are updated as needed.
Are the guides written by an appraiser?
Yes. Content is written and reviewed by Austin, a California-licensed real estate appraiser with 14 years of experience. The guides reflect actual day-to-day appraisal practice, not just theory.
