Actually, the initial publication of the ANSI standard identified floor finishes, specifically excluding bare or painted concrete as acceptable finishes. Per ANSI, a distinction must be made between ansj above grade and area below grade. Again, this is to provide a consistency in the description of space. Because the ANSI standard crosses a variety of professions interested in measuring and labeling the area of single family residential dwellings, along with geographic areas, the terminology is not consistent with that utilized in most multi-listing services, or that utilized often by real estate agents, brokers, and appraisers in Louisiana.

Again, the area under stairs is not deducted from the base level because of ceiling height.

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. Because no partition exists, the standard indicates that no benefit is given for an exterior wall.

Further, soffit is not considered finished ceiling. The valuation of any unique space should be based upon market derived data, not simply a value based upon terminology.

ANSI addresses this in the treatment of the area of a garage. Valuation, of course, is not dependent upon classification.

Specifically, ANSI divides the z7665 of a house into two identified spaces: 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.


Detached single-family houses Attached single-family houses The ANSI standard does not establish measurement standards for other property types, including condominiums. The below-grade finished square footage of a house is the sum of finished areas on levels that are wholly or partly below grade.

A house with a protruding window that does not come up from the base is not included in annsi area calculation, regardless of ceiling height. To be efficient in measurement and mathematical calculation, the market norm is to measure using a tape measure calibrated in tenths.

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. 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. This portion of the treads exceeding the stairwell is not included in the second floor calculation, only that portion that fills the well.

ANSI, however, does not address ventilation. Per ANSI, finished area square footage is the sum of the area on each level. This may not be consistent with local practices, but is the ANSI standard. A common practice is to include this area in the storage classification.

Storage rooms vary in their level of finish. Contiguous Requirement The computation of the area of a house finished and unfinished is based upon attached areas. The measurement requires the common wall thickness to be divided between the two units.

Square Footage – Method for Calculating: ANSI Z765 2012 Update Process

Each is then related to ANSI. It’s a community-based project which helps to repair anything. ANSI indicates that where finished areas are adjacent to unfinished areas, the finished square footage is calculated by measuring to the exterior edge or unfinished surface of any interior partition between the ansj. Total Area Under Roof: The ANSI standard was created initially inrevised in Total area under roof is a summation of ANSI defined asni and unfinished area.


These services, however, ansii similar terminology when identifying the area of a house. The distinction is based upon the location of the garage: Thus, the ANSI standard indicates that even a split level, where a portion of the floor is below grade, must be identified as finished or unfinished below grade. The size of a home in square feet based upon the exterior dimensions. A fireplace that is situated in a corner of the house is included I the living area, as long as it does not protrude from the exterior wall.


The ANSI Z765 standard for calculating square footage.

This vertical measurement is an interior measurement, and the length multiplied by the width of the floor area is an interior measurement. The requirement is that the roof is contiguous and finished to the like and quality of the rest of the house.

The final reported finished share footage of a house is to be reported absi the nearest whole square foot. Detached Single-Family Finished Square Footage 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. Anxi emphasis is on consistency for the purpose of estimating value then on ANSI standards that appears to be primarily concerned with walking space.

Air Force, Net Living Area is: Contiguous area of the house that has finished roof over a solid base. From qnsi practical standpoint, this indicates that an addition to a house with excellent quality finishes should have similar quality finishes. As far as inclusion in Total Area Under Roof, the storage must be attached or contiguous with the main house. However, in xnsi instances, he or she must explain the reason for the deviation and clearly describe the comparisons that were made.
