With all the confusion that can be create in what is the square footage of your listing, its no wonder that many real estate agents opt not to measure the property, but take the information from a secondary source. However that secondary source may not be the best representation of the property, your listing. The best source is someone that knows the differences and understands what your obligation is. 

Street Appraisal can offer your company a detailed sketch with interior and exterior photographs to enhance your presentation saving you time to do what you do best, SELL HOMES!  

Appraisers analysis everything, and essentially back up what and how the square footage of a property is determined based on what we are doing the measurements for. In most cases, we are providing an appraisal to meet secondary market guidelines, most commonly identified as Fannie Mae and Freddie Mac.

Fannie Mae Guidelines: XI, 405.05: Gross Living Area (11/01/05)

The most common comparison for one-family properties (including units in PUD, condominium, or cooperative projects) is above-grade gross living area. The appraiser must be consistent when he or she calculates and reports the finished above-grade room count and the square feet of gross living area that is abovegrade. For units in condominium or cooperative projects, the appraiser should use interior perimeter unit dimensions to calculate the gross living area. In all other instances, the appraiser should use the exterior building dimensions per floor to calculate the above-grade gross living area of a property. Only finished abovegrade areas should be used, garages and basements (including those that are partially above-grade) should not be included. We consider a level to be belowgrade if any portion of it is below-grade regardless of the quality of its finish or the window area of any room. Therefore, a walk-out basement with finished rooms would not be included in the above-grade room count. Rooms that are not included in the above-grade room count may add substantially to the value of a property particularly when the quality of the finish is high. For that reason, the appraiser should report the basement or other partially below-grade areas separately and make appropriate adjustments for them on the basement and finished areas below-grade line in the sales comparison analysis grid. To ensure consistency in the sales comparison analysis, the appraiser generally should compare above-grade areas to above-grade areas and below-grade areas to below-grade areas. The appraiser may deviate from this approach if the style of the subject property or any of the comparables does not lend itself to such comparisons. However, in such instances, he or she must explain the reason for the deviation and clearly describe the comparisons that were made Then there is Gross Building Area or GBA: Gross Building Area sometimes can be the same as GLA (Gross Living Area) and is especially true for single family homes. However, in a multi-family residence there maybe common areas that would not be considered living areas, but part of the size of the structure.

Gross building area, XI, 405.06: Gross Building Area (11/01/05):

Which is the total finished area (including any interior common areas, such as stairways and hallways) of the improvements based on exterior measurements, is the most common comparison for two-family to fourfamily properties. The gross building area must be consistently developed for the subject property and all comparables that the appraiser uses. It should include all finished above-grade and below-grade living areas, counting all interior common areas (such as stairways, hallways, storage rooms, etc.), but not counting exterior common areas (such as open stairways). We will accept the use of other comparisons for two-family to four-family properties (such as the total above-grade and below-grade areas as discussed above in Section 405.06, as long as the appraiser explains the reasons he or she did not use a gross building area comparison and clearly describes the comparisons that were made. So Again, the major difference between GLA and GBA in a multi-family is what is actually used as living space, or rented out GLA, and basically how big the building is or GBA. So that is pretty simple, not tough at all. Square footage calculation of single family residence by the American National Standard Institute or ANSI has a slightly different approach. ANSI Z765-2003 standards have been adopted by most MLS services and real estate agents.

ANSI Z765-2003 standards: 

For detached single-family houses, the finished square footage of each level is the sum of finished areas on that level measured at floor level to the exterior finished surface of the outside walls.

Openings to the floor below: Cannot be included in the square footage calculation. However, the area of both stair treads and landings proceeding to the floor below is included in the finished area of the floor from which the stairs descend, not to exceed the area of the opening in the floor. So while the Fannie Mae guidelines would include open areas (such as the stair well and cathedral area over living room, in their determination of GLA, ANSI standards do not. There is a simple reason for that: Fannie Mae wants the appraiser to measure the GLA of the subject consistently with how the GLA is measured on the comparables. Since appraisers do not get in to inspect the interior of the comparables they can not determine open area from non-open area. Again open areas are included in GLA defined by Fannie Mae, but are not included as determined in GLA as defined by ANSI standards.

Above and Below Grade Finished Areas: The above-grade finished square footage of a house is the sum of finished areas on levels that are entirely above grade. The below-grade finished square footage of a house is the sum of finished areas on levels that are wholly or partly below grade. Fannie Mae and ANSI are both consistent with this definition. Any level that is partially below grade makes the entire area ineligible for being determined in GLA. Woops again: Fannie may states: The appraiser may deviate from this approach if the style of the subject property or any of the comparables does not lend itself to such comparisons. However, in such instances, he or she must explain the reason for the deviation and clearly describe the comparisons that were made So as long as the appraiser can define consistent comparables with below grade and above grade areas, and they give reasonable cause, below grade areas can be included.

Ceiling Height Requirements:

To be included in finished square footage calculations, finished areas must have a ceiling height of at least 7 feet (2.13 meters) except under beams, ducts, and other obstructions where the height may be 6 feet 4 inches (1.93meters); under stairs where there is no specified height requirement; or where the ceiling is sloped. If a room’s ceiling is sloped, at least one-half of the finished square footage in that room must have a vertical ceiling height of at least 7 feet (2.13 meters); no portion of the finished area that has a height of less than 5 feet (1.52 meters) may be included in finished square footage. Again, Fannie Mae differs and again because they are considered with the accuracy of an analysis not  necessarily the particulars of a property. That is not to say if the appraiser is aware of an inconsistency or unique property, they are not to take it into consideration. For example: Two capes 24 feet wide with a full dormer on one side. The width on the second floor may be 20 feet. Four feet has been taken away from the width of the second floor to accommodate or meet the requirements that GLA is defined as a minimum of 5 feet. Yet we know that some homes may have been finished off to accommodate 6 feet of living area, creating additional eve storage but reducing living area. In this particular situation, GLA would be different based on ANSI standards which would eliminate that area, and Fannie Mae, which is based on the exterior measurements, would include this area. Again, how would an appraiser know if a comparable only had 18 feet wide living area on the second floor if they had not inspected the interior of the comparable sale? The emphasis is on consistency for the purpose of estimating value then on ANSI standards that appears to be primarily concerned with walking space. Typically appraisers agree to ANSI standards that Fannie Mae does not address. They are: Finished areas that are connected to the main body of the house by other finished areas such as hallways or stairways are included in the finished square footage of the floor that is at the same level. Finished areas that are not connected to the house in such a manner cannot be included in the finished square footage of any level. Where finished and unfinished areas are adjacent on the same level, the finished square footage is calculated by measuring to the exterior edge or unfinished surface of any interior partition between the areas.

NOW: Assessors, Insurance Agents, Architects, Contractors and Mobile Home dealers all have different ways of measuring a property. A prime example is assessors may measure a New England home as 1.75 story building while the exterior measurements and the interior measurements and ceiling height measurements may constitute the property being a full 2 story building.
