What is Gross Living Area (GLA) and How Do You Calculate It?
Knowing how to calculate the Gross Living Area (GLA) of a residential or commercial property is a vital part of creating the appraisal report and estimating the worth of a home. This article walks you through the actions on how to compute GLA with self-confidence.
What is Gross Living Area (GLA)?
Property is measured after regional policies worldwide. In the US, Gross Living Area (GLA) is specified by the Appraisal Institute's Dictionary of Real Estate Appraisal, 7th Ed., as the total area of completed, above-grade (in the air) domestic area. It is calculated by determining the outside border of the structure and includes just finished, habitable, above-grade living space. Finished basements and attic locations are not normally consisted of in the GLA overall. However, local practices vary on this.
GLA is a vital part of the evaluation of a home or residential or commercial property. It is not the exact same as total living location (TLA). Although the Appraisal Institute does not strictly specify TLA, it is typically required to include any finished basement area, habitable attic areas, and even unattached accessory house units.
Why is it Important to Know the Exact GLA of a Home?
The livable, above-ground space in a home is the part of the home that commands the greatest cost. The assessment of the residential or commercial property is typically a direct outcome of just how much of the residential or commercial property's space has this condition and will, in turn, straight effect insurance coverage costs and value and, eventually list prices.
Because of this, it is very important that the appraiser include every legitimate area in a GLA calculation so that the residential or commercial property achieves its rightful list prices, the mortgage lending institution knows the proper value, and the residential or commercial property is appropriately guaranteed.
How is Gross Living Area Measured and Calculated?
Historically, GLA has been open to interpretation in how it was determined, with appraisers, remodelers, and the like using various meanings and calculations. In the United States, the American National Standards Institute (ANSI) just recently introduced ANSI Z765-2021 to document typical standards for appraisers.
Some companies, such as Fannie Mae, a leading source of mortgage funding in the United States, now require appraisers to utilize these standards and provide a helpful introduction document.
The ANSI home measurement requirement has a few crucial elements:
- It uses to single-family housing. It does not use to apartment or condos, apartments, or commercial residential or commercial property.
- It defines Gross Living Area (GLA) and what to include or exclude from the estimation.
- Measurements are kept in mind to the nearest inch or tenth of a foot and reported on a sketch or layout of the residential or commercial property. The last square footage calculation is to be reported to the closest entire square foot.
What Is Included in the GLA Calculation?
For an area to be included as GLA, it should adhere to these six criteria:
It needs to be completed. It needs to consist of walls, floors, and ceilings, finished with standard materials such as carpet, drywall, and so on. It must be above ground. Even an area simply 2 ft listed below ground counts as basement area and is left out. It has actually to be confined. It should have 4 walls. It needs to be contiguous. It should be linked to the remainder of the Gross Living Area. It must be traditionally warmed, using forced air, solar, radiant heat, etc (space heating units do not count). It must be permitted. The regional city or county structure department need to have allowed the location. If a location meets all these components, include it in the GLA. Note that the external walls for included locations become part of the measurement. An area is omitted from the GLA if any of the above criteria are unmet. Instead, it can be noted as a separate line product in the report and consisted of as part of the TLA.
What Are Non-GLA Areas in a Residential or commercial property?
As the GLA is the overall of the above-ground property space of adjoining, completed locations, it is necessary to comprehend which locations of a residential or commercial property are not consisted of in the GLA calculation. These areas are, nevertheless, frequently consisted of in the computation of TLA.
Examples of locations that are not consisted of in the GLA estimation are:
- Unfinished garages. - Below-grade (listed below ground level) spaces such as basements. This includes walk-out basements - ones with direct access to the outdoors - normally found in a home built on a slope. Instead, list them in the TLA. - Finished sheds or structures not linked to the main building, such as cottages or Accessory Dwelling Units (ADU). Instead, list them in the TLA.
- Finished areas that are only connected to the primary living area by an unfinished area - simply put, they are not linked by a finished and warmed corridor or staircase. For instance, a visitor suite connected to the primary home by means of an incomplete garage. Instead, list them in the TLA.
- Finished living spaces where over half of the ceiling location is less than 7-foot-high. If the ceiling slopes (such as in an attic), any location with less than a 5-foot ceiling height must be omitted from the GLA.
- Covered or uncovered patio areas and decks.
- Porches that are not enclosed, or if enclosed, are not ideal for year-round usage. These are often called three-season rooms.
- Openings in a level that look down to the flooring below, such as a vestibule or foyer.
- Bump-outs that do not have a flooring. For example, a cantilevered window-seat bump-out.
- A fireplace is left out if it is surrounded on three sides by external walls.
- A space that was constructed or renovated without a suitable permit.
5 Practical Tips on How to Measure GLA On-Site
Start with a walkaround - Walk the beyond the home or residential or commercial property to get a concept of the shape of the residential or commercial property. Sketch on paper or tablet - Make a fast sketch of the residential or commercial property shape on paper or develop a digital sketch using floor strategy software on your tablet. Start determining - work your way from corner to corner and use a tape measure, roto wheel, or a laser to get the appropriate measurements. Round your measurements to the closest inch or the nearby 1/10th of a foot so you comply with the ANSI standard. Head inside - Make sure to go inside the residential or commercial property and measure any areas that do not meet GLA standards. These areas should be listed as TLA. Do the math - Total all the locations that comply with GLA requirements - this is the GLA. Then build up the locations that are non-GLA, and include these to your GLA location, which offers you your TLA. Bonus Tip! Use Software to Double-Check Your Calculation
Make a professional layout sketch total with measurements and annotations, and include this as part of your appraisal report. This provides complete transparency on how you pertained to your calculation and offers you the self-confidence you have actually reached the right number.
Pick layout software application like RoomSketcher, as here you get a built-in overall location calculator that you can utilize to verify your measurements. If everything matches up, then fantastic! If not, inspect that you have actually gone into the same measurements into RoomSketcher as in your manual calculations, and evaluate your manual computations for any mistakes or oversights.

GLA vs. Total Living Area (TLA)
While GLA is the ended up, connected, above-ground space in a home, Total Living Area (TLA) typically consists of below-ground finished area and non-connected (or non-contiguous) area.
Total Living Area includes, for instance, ended up basement area and separate completed structures such as cottages and accessory residence units. Additionally, heated, completed attic areas would be included as long as majority the location has a ceiling height of 7 feet or more. In the case of an inclined ceiling in the attic, only the area with a height of five feet or more is counted.
If you utilize layout software application like RoomSketcher to draw your professional flooring plan, you can establish any area to exclude, so the automated computation doesn't include this location.
GLA vs. Gross Building Area (GBA)
Whilst GLA is the requirement for single-family homes, multi-family residential properties with two to four units are typically determined using Gross Building Area (GBA). Both GLA and GBA calculate the finished areas of a structure.
The main distinction is that below-grade home is consisted of in the Gross Building Area. Like GLA, GBA consists of completed hallways, storeroom, utility room, and interior stairs.
GLA vs. Gross Internal Area (GIA)
Gross Internal Area (GIA) is typically used for commercial structures. The Gross Internal area (GIA) is the entire enclosed internal flooring space, measured to the inside face of the exterior walls.
This measurement can offer industrial building leases an idea of the usable interior floor area. The measurement includes any space utilized by internal walls or partitions, along with hallways, bathrooms, and storage rooms. It may likewise consist of garages and basements.
GLA vs. Total Square Footage
There is no "official" meaning of total square video footage. Rather total square video footage is utilized to explain the square video of a specified location. You could, for instance, report the overall square video of the garage, which would not indicate whether the garage was finished or contiguous with the home.
The GLA just consists of above-grade, completed, contiguous areas of a home whilst the overall square video includes other areas (that might not be living areas) as long as they have walls, ceilings, and floorings.
Total Square Footage can consist of garages, workshops, unfinished storage locations, porches, patios - any area under the primary roof, in addition to separated structures like different garages, guest suites, or cabanas.

Frequently Asked Questions (FAQ):
Are external walls consisted of in the GLA computation?
Mostly. A GLA computation includes the external walls for the rooms, areas, and staircase, which fulfill the GLA standard, so just the exterior walls of those areas are consisted of.
Is a garage consisted of in the Gross Living Area?
No, unless it has been permitted and transformed into an above-grade, contiguous, completed, heated up, habitable space.
Are closets consisted of in Gross Living Area?
Generally, yes, if they meet the height requirements.
Are stairs included or excluded in GLA?
The stair treads and landing areas are thought about part of the room from which they come down, so if that room is considered part of GLA, so is the stair location. If the stair opening is larger than the stairs, then only the stairs (treads and landings) are included in the GLA for the flooring from which the stairs descend.
How do you compute stairs in Gross Living Area?
The stair tread and landings are consisted of in the Gross Living Area for the level from which they come down. For example, stairs coming down from a 2nd level to the ground floor are counted in the GLA of the second level.
Any area beneath the is consisted of in the square footage of the flooring to which the stairs come down. So the location underneath the staircase in our example is included in the GLA for the ground flooring.
Note that if the opening to a stairwell is the exact same size as the stairs, then the whole opening belongs to the GLA for the floor from which the stairs come down. If the opening is wider than the stairwell, then include just the area equivalent to the size of the stairs (in the GLA for the flooring from which the stairs descend).
Are fireplaces consisted of or excluded in the GLA?
If a fireplace is surrounded on 3 sides by external walls, it is not part of GLA.
Is the attic included in the GLA?
Finished attics are common in lots of areas. According to the definition of GLA from the Appraisal Institute, attics are not usually included in the GLA. However, regional practices on this differ. In numerous areas, an attic's location can be included in the GLA as long as it is heated and completed.
If there is a sloped ceiling in the attic, then the ANSI Z765-2021 standard states that you can only consist of the floor location where the ceiling determines five feet up. Furthermore, at least one-half of the finished flooring area need to have seven feet of ceiling height.
Take Your Appraisals to the Next Level
Appraising is an important job needing precision and attention to information. There are usually recognized measurement standards depending on the area in which you live. Some of the standards now need computer-generated sketches for appraisal reports.
