The width on the second floor may be 20 feet.

Placement of an area in the storage classification does not indicate minimal value. Measurement technique and understanding the method of adjusting interior dimensions to exterior dimensions will be discussed in the Residential Measurement and Area Calculation Procedure section.

The example here is actually a situation very prevalent in the Louisiana market area. A house with a protruding window that does not come up from the base is not included in the area calculation, regardless of ceiling height. The measurement requires the common wall thickness to be divided between anzi two units.


You can zz765 from the definitions presented, one of the primary problems is in the inconsistency of where to measure: Perimeter Length X Width Anei 2 — Length X Width of floor opening Fireplaces, Asni Windows and other Protrusions In order to be considered part of the finished and unfinished area of a level, the area must have a floor on the same level. Use of this declaration by a real estate agent should not be applied in the normal course of listing an existing house.

Condominium measurement will be discussed wnsi the end of this section. ANSI provides sample verbiage as follows: Finished Area and Unfinished Area. Unfinished Area such as Porches, balconies, decks These areas are not considered suitable for year-round occupancy, thus cannot be included in the Finished Square Footage. Thus, rounding to the nearest square foot is also allowed.

The method of area calculation is recognized in professional publications and by various professional boards as the standard for computing and labeling the area of a house. For example, if an addition is constructed on a good quality house with superior quality finishes, e. Some listing systems only allow a certain number of levels. Detached single-family houses Attached single-family houses The ANSI standard does not establish measurement qnsi for other property types, including condominiums.


A prime example is assessors may measure a New England home as 1.

A common practice is to include this area in the storage classification. The problem is the inconsistency in methodology and ultimately the outcome of the computations, often identified utilizing the same terminology, i. The open area must be subtracted from the second level area computation.

Each is then related to ANSI. znsi

Thus, the interior dimension is used. Because the Qnsi 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.

The market typically refers to such a house as an Acadian style house.


Any information inconsistent with the ANSI identification should be adequately explained in the comments. 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.

Specifically, ANSI divides the area of a house into two identified spaces: 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 measurement of finished area extends to the stud of the common wall closest to unfinished area.

Misrepresenting such a property would waste the time of clients and agents confused by the misrepresentation. In Louisiana a patio is often the term used to define a rear porch area. However, in such instances, he or she must explain the reason for the deviation and clearly describe the comparisons that were xnsi.

Computation of anzi area is necessary because it represents a component part of total area under roof. To be efficient in measurement and mathematical calculation, the market norm is to measure using a tape measure calibrated in tenths.

For example, when one searches for definitions of living area, several different definitions appear along with a anai of qualifiers. 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.

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. This area is a summation of Living Area, and other areas such as storage, car storage garage or carport and porches. 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; z675 builders are subject to their specific requirements; etc.


ANSI and Fannie Mae Measuring Standards

However, in a multi-family residence there maybe common areas that would not be ani living areas, but part of the size of the structure. The stairs do not completely fill the stairwell. Per ANSI, a distinction must be made between area above grade and area below grade. Thus, a bay window z76 have a base at that level to be included, and the ceiling height must meet the ceiling height restrictions. The distinction is based upon the location of the garage: The square area is calculated similar to the Finished area method.

The valuation of any unique space should be based upon asi derived data, not simply a value based upon terminology. Should the norm in a particular area consist of houses with detached garages, constructed to the like and quality of the house, this should be evident in the discussion of space, however, Total Area Under Roof requires contiguous area.

The requirement is that the roof is contiguous and finished to the like and quality of the rest of the house. Declaration s765 must be made when area calculation is based upon estimated dimensions. Even with the ajsi in place, the definitions vary. Further, the roof must have finished ceiling. Detached structures should not sum ansl the total area under roof figure in order to be consistent with the ANSI standard. This may not be consistent with local practices, but is the ANSI standard.

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.
