The classification of such detached areas is typically done 7z65 the amenity category and the area discussed in the comment section. Perimeter Length X Width X 2 — Length X Width of floor opening Fireplaces, Bay Windows and other Protrusions In order to be considered part of the finished and anssi area of a level, the area must have a floor on the same level.

The measurement of finished area extends to the stud of the common wall closest to unfinished area. Any level that is partially below grade makes the entire area ineligible for being determined in GLA.

These services, however, utilize similar terminology when identifying the area of a house. This means that some rounding to the closest inch or tenth is allowed ansk the linear dimensions. While not all licensees utilize such systems to list property, it is a very common practice to use the information provided in these systems as a resource in the marketplace. This indicates that a finished area under roof that is accessed through a garage, carport or breezeway is not to be included in the finished square footage calculation for that level.

The below-grade finished square footage of a house is the sum of finished areas on levels that annsi wholly or partly below grade. For example, a repossessed house without allowed access to the interior.

As a result, there was and still remains today inconsistencies amongst various professions involved in single family residential measurement and area calculation, in addition to variances within the same profession operating in different market areas. It is evident that the treads do not completely fill the well.

Real Estate Agents and Brokers are subject to the requirements of various professional boards; appraisers are subject to the guidelines of their users such as FHA, VA, Fannie Mae and Freddie Mac; architects are subject to their professional requirements; property managers subject to their specific requirements; home builders are subject to their specific requirements; xnsi. Since appraisers do not get in to inspect the interior of the comparables they can not determine open area from non-open area.


The above-grade finished square footage of a house is the sum of finished areas on level that are entirely above grade. Placement of an area in the storage classification does not indicate minimal value. Even with the qualifiers in place, the definitions vary.

Thus, a bay window must have a base at that level to be included, and the ceiling height must meet the ceiling height restrictions. The final reported finished share footage of a house is to be reported to the nearest whole square foot. In Louisiana a patio is often the term used to define a rear porch area. Understand that different boards may have varying requirements; however, it is obvious that consistent like and quality is key.

Examples of this occur in many houses with exterior accessed storage rooms and garages. Thus, detached buildings such as storage sheds, guest houses, pool a765, etc.

Subsequent to this identification, the area is then identified as Finished or Unfinished area. Finished Areas Adjacent to Unfinished Areas 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.

Specifically, ANSI divides the area of a house into two identified spaces: By definition a storage room is a room in which things are stored. This total should include the square footage of the main home as well as the square footage of the wing or addition if one has been specified.

ANSI states the measurement of such areas is also based upon a linear measure of the exterior finished surface of the house to the outer edge of the floor surface area or exterior surfaces. Per AccuCoverage insurance agencyLiving Area is: The standard provides a uniform method of measuring and consistent defined terms.



As far as inclusion in Total Area Under Roof, the storage must be attached or contiguous with the main house.

The snsi may deviate from this approach if the style of the subject property or any of the comparables does not lend itself to such comparisons.

Valuation, of course, is not dependent upon classification. Thus, rounding to the nearest square foot is also allowed.

ANSI and Fannie Mae Measuring Standards

Other inconsistencies exist in defining the degree of finishes needed to be considered living area, the handling of stairs, the ceiling height requirements, accessibility, ventilation requirements, etc. Total Area Under Roof: Obviously a portion of the treads do not fill the stairwell or opening. Per ANSI ceiling height must be considered when computing area. However, in such instances, he or she must explain the reason for the deviation and clearly describe the comparisons that were made.

However, if a buyer desires a three bedroom house and a guest house, the guest house should be searched through the amenity or comments category. So while Fannie Mae guidelines would include open area such as the stair well and cathedral area over living room, in their determination of GLA, ANSI standards does not.

Such a variety of definitions and measurement techniques produce an inability to accurately communicate property size information between professionals of various professions and members of the same profession in different locations. The ceiling height limitations caused by the roof line must be considered to provide an ANSI compliant area calculation.

As appraisers we analyze everything, including how the square footage of a property is measured and calculated. National Measurement Standard Some of this inconsistency has been eliminated by the wide acceptance of a common measurement standard created ina standard that provides consistency between organizations and between geographic areas. Connections include rooms, hallways or stairways. Level Per ANSI a level includes areas of the house that are vertically within 2 feet of the same horizontal plane.
