Evaluating Above-Grade Room Count (from Fannie Mae Guidelines)
The most common comparison for one-unit properties is the above-grade gross living area.
Appraisers must be consistent when calculating and reporting finished above-grade room count
and square footage for the gross living area above-grade.
A level is considered below-grade if any portion of it is below-grade—regardless of the quality
of its finish or the window area of any room. A walk-out basement with finished rooms would
not be included in the above-grade room count.
For units in condo or co-op projects, the appraiser must use interior perimeter unit dimensions to
calculate the gross living area. In all other instances, the appraiser must use the exterior building
dimensions per floor to calculate the above-grade gross living area of a property.
The following must be observed when calculating and reporting above-grade room count and
square footage for the gross living area:
• Only finished above-grade areas can be used in calculating and reporting of above-grade room
count and square footage for the gross living area.
• Garages and basements, including those that are partially above-grade, must not be included in
the above-grade room count.
