Further, the definition indicates the area must be contiguous and have finishes. Obviously a portion of the treads do not fill the stairwell or opening. The ceiling height limitations caused by the roof line must be considered to provide an ANSI compliant area calculation. The ANSI standard even identifies acceptable finishes. Examples of this occur in many houses with exterior accessed storage rooms and garages.

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.

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. The roof is removed and the view demonstrates the perimeter wall thickness, along with a thickness of the common wall. 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. The computation of area is based upon exterior dimensions: The best source is someone that knows the differences and understands what sales agent’s obligations are.

Market practices are sometimes inconsistent in this interpretation and include an exterior wall thickness adjustment to the length of the interior dimension to equate the dimensions to an exterior dimension.

ANSI looks at the outside dimensions, but also may “extract” a few areas in the interior and provides some ajsi guidance when it comes to unique properties. Finished Area and Unfinished Area. For instance, a townhouse adjoining another znsi has a common wall. Ceiling Ajsi Requirements To be included in finished square footage calculations, finished areas must have a ceiling height of at least 7 feet 2. Air Force, Net Living Area is: Further, the roof must have finished ceiling.

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.

Thus, rounding to the nearest square foot is also allowed. Know that the ANSI standard makes no statement concerning differences between square footage calculations made by multiple parties for the same property.

Assessors, Insurance Agents, Architects, Contractors and Mobile Home dealers all have different ways of measuring a property. Subsequent to this identification, the area is then identified as Finished or Unfinished area. Without another description, this type of space is typically placed in storage.

ANSI and Fannie Mae Measuring Standards

Such a variety of definitions ansk 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.

Should the norm in a particular area consist of houses with detached garages, constructed to the annsi and quality of the house, this should be evident in the discussion of space, however, Total Area Under Roof requires contiguous area. To be efficient in measurement and mathematical calculation, the market norm is to measure using a tape measure calibrated in tenths.

By definition a storage room z7655 a room in which things are stored. 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.

ANSI acknowledges that it is a common practice to provide a floor opening for stairs that is the same size as the stairs themselves. 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 ansu level measured at floor level to the exterior finished surface of the ahsi walls.

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. Total area under roof is a summation of ANSI defined finished and unfinished area.

The ANSI Z765 standard for calculating square footage.

Placement of an area in the storage classification does not indicate minimal value. However, know that in Louisiana, the typical custom is to include a garage as part of the unfinished area, if attached to the house, and include the summation of this area with finished area to determine the total area under roof.

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.

For example, when one searches for definitions of living area, several different definitions appear along with a combination of qualifiers. The open area must ansii subtracted from the second level area computation. ANSI also describes such a case when physical access to the structure is not possible due to the nature of the terrain or other obstacles that may preclude direct anssi measurement of the exterior in the time available.

The z756 may deviate from annsi approach if the style of the subject property or any of the comparables does not lend itself to such comparisons.

UNDERSTANDING ANSI-Z765 STANDARDS FOR SINGLE FAMILY

Declaration 3 must be made when area calculation asni based upon estimated dimensions. The square area is calculated similar to the Finished area method. The final reported finished share footage of a house is to be reported to the nearest whole square foot. Condominium measurement will be discussed at the end of this section.

From a logical standpoint, if a client is in the market for a house with three bedrooms to service the needs of the young family, the search results of a three bedroom house should not include a two bedroom house with a detached guest house. It is anso that the treads do not completely fill the well. A fireplace that is situated in a corner of the house is z675 I the living area, as long as it does not protrude from the exterior wall.

A common practice is to include this area in the storage classification. This means that some rounding to the closest inch or tenth is allowed in the linear dimensions. An example of this is a second story finished area with a door leading to unfinished storage.

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 stairs do not completely fill the stairwell.

Measurement of finished area extends to the inside surface of the garage.
