What is Gross Living Area (GLA)?
Real estate is determined after regional guidelines 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 location of ended up, above-grade (above the ground) domestic area. It is computed by determining the outdoors perimeter of the structure and includes only ended up, habitable, above-grade living space. Finished basements and attic locations are not generally included in the GLA total. However, regional practices vary on this.
GLA is a critical part of the appraisal of a home or residential or commercial property. It is not the exact same as overall living location (TLA). Although the Appraisal Institute does not strictly define TLA, it is typically required to consist of any completed basement area, habitable attic locations, and even unattached accessory residence systems.
Why is it Important to Know the Exact GLA of a Home?
The habitable, above-ground space in a house is the part of the home that commands the biggest price. The valuation of the residential or commercial property is typically a direct result of how much of the residential or commercial property's space has this condition and will, in turn, directly effect insurance expenses and value and, ultimately sales cost.
Because of this, it is necessary that the appraiser include every legitimate location in a GLA computation so that the residential or commercial property accomplishes its rightful sales cost, the mortgage lending institution knows the correct value, and the residential or commercial property is correctly guaranteed.
How is Gross Living Area Measured and Calculated?
Historically, GLA has actually been open to analysis in how it was determined, with appraisers, remodelers, and so forth utilizing different definitions and computations. In the United States, the American National Standards Institute (ANSI) recently presented ANSI Z765-2021 to record common standards for appraisers.
Some organizations, such as Fannie Mae, a leading source of mortgage financing in the United States, now need appraisers to use these requirements and supply a practical summary document.
The ANSI home measurement requirement has a couple of key elements:
- It uses to single-family housing. It does not apply to apartments, apartments, or commercial residential or commercial property.
- It defines Gross Living Area (GLA) and what to include or exclude from the computation.
- Measurements are noted to the closest inch or tenth of a foot and reported on a sketch or floor strategy of the residential or commercial property. The last square video footage estimation is to be reported to the nearby whole square foot.
What Is Included in the GLA Calculation?
For an area to be included as GLA, it must follow these 6 requirements:
It needs to be ended up. It needs to consist of walls, floors, and ceilings, ended up with standard materials such as carpet, drywall, etc. It should be above ground. Even a space just 2 feet listed below ground counts as basement area and is left out. It needs to be enclosed. It needs to have four walls. It requires to be adjoining. It should be linked to the rest of the Gross Living Area. It needs to be conventionally heated, utilizing forced air, solar, radiant heat, and so on (space heating systems do not count). It should be permitted. The regional city or county structure department need to have permitted the location. If a location satisfies all these components, include it in the GLA. Note that the external walls for included areas are part of the measurement. An area is omitted from the GLA if any of the above requirements are unmet. Instead, it can be kept in mind as a different 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 domestic area of contiguous, ended up areas, it is very important to understand which areas of a residential or commercial property are not consisted of in the GLA calculation. These locations are, however, typically consisted of in the computation of TLA.
Examples of areas that are not included in the GLA computation are:
- Unfinished garages. - Below-grade (below ground level) spaces such as basements. This consists of walk-out basements - ones with direct access to the outside - generally found in a home built on a slope. Instead, list them in the TLA.
- Finished sheds or structures not connected to the main structure, such as cottages or Accessory Dwelling Units (ADU). Instead, list them in the TLA.
- Finished locations that are just connected to the main living space by an unfinished area - to put it simply, they are not connected by a finished and heated passage or staircase. For instance, a guest suite connected to the primary home through an incomplete garage. Instead, list them in the TLA.
- Finished living spaces where majority of the ceiling area 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 need to be omitted from the GLA.
- Covered or discovered outdoor patios and decks.
- Porches that are not enclosed, or if enclosed, are not ideal for year-round usage. These are typically called three-season spaces.
- Openings in a level that look down to the floor listed below, such as a vestibule or foyer.
- Bump-outs that do not have a flooring. For instance, a cantilevered window-seat bump-out.
- A fireplace is omitted if it is surrounded on 3 sides by external walls.
- A room that was built or renovated without a suitable authorization.
5 Practical Tips on How to Measure GLA On-Site
Start with a walkaround - Walk around the beyond the home or residential or commercial property to get an idea of the shape of the residential or commercial property. Sketch on paper or tablet - Make a quick sketch of the residential or commercial property shape on paper or create a digital sketch utilizing layout software on your tablet. Start measuring - work your way from corner to corner and utilize a tape step, roto wheel, or a laser to get the appropriate measurements. Round your measurements to the closest inch or the closest 1/10th of a foot so you abide by the ANSI standard. Head inside - Make sure to go inside the residential or commercial property and measure any areas that don't satisfy GLA standards. These locations should be listed as TLA. Do the mathematics - Add together all the areas that adhere to GLA requirements - this is the GLA. Then build up the locations that are non-GLA, and add these to your GLA location, which provides you your TLA. Bonus Tip! Use Software to Double-Check Your Calculation
Make a professional layout sketch complete with measurements and annotations, and add this as part of your appraisal report. This provides total transparency on how you pertained to your computation and gives you the confidence you have actually shown up at the ideal number.
Pick layout software like RoomSketcher, as here you get an inbuilt total area calculator that you can use to verify your measurements. If whatever matches up, then excellent! If not, inspect that you've entered the same measurements into RoomSketcher as in your manual calculations, and review your manual computations for any mistakes or oversights.

GLA vs. Total Living Area (TLA)
While GLA is the completed, connected, above-ground area in a home, Total Living Area (TLA) usually consists of below-ground completed space and non-connected (or non-contiguous) space.
Total Living Area includes, for example, finished basement area and different completed buildings such as cottages and accessory dwelling systems. Additionally, heated, finished attic spaces would be included as long as majority the area has a ceiling height of 7 feet or more. In the case of a slanted ceiling in the attic, just the area with a height of five feet or more is counted.
If you use layout software application like RoomSketcher to draw your expert floor strategy, you can establish any space to omit, so the automated computation doesn't include this location.
GLA vs. Gross Building Area (GBA)
Whilst GLA is the standard for single-family homes, multi-family homes with two to 4 units are often determined utilizing Gross Building Area (GBA). Both GLA and GBA calculate the ended up areas of a structure.
The primary difference is that below-grade home is included in the Gross Building Area. Like GLA, GBA includes completed corridors, storage spaces, laundry rooms, and interior stairs.
GLA vs. Gross Internal Area (GIA)
Gross Internal Area (GIA) is often utilized for business structures. The Gross Internal area (GIA) is the whole enclosed internal flooring space, measured to the within face of the exterior walls.
This measurement can provide business building rents an idea of the functional interior floor area. The measurement consists of any area utilized by internal walls or partitions, along with hallways, bathrooms, and storeroom. It might likewise consist of garages and basements.
GLA vs. Total Square Footage
There is no "official" definition of total square video footage. Rather overall square video is utilized to explain the square video footage of a specified location. You could, for instance, report the total square video footage of the garage, which would not show whether the garage was ended up or contiguous with the home.
The GLA only consists of above-grade, ended up, contiguous areas of a home whilst the overall square video includes other locations (that might not be living areas) as long as they have walls, ceilings, and floorings.
Total Square Footage can include garages, workshops, incomplete storage areas, porches, patios - any area under the main roofing, in addition to removed 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 consists of the external walls for the spaces, locations, 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 actually been permitted and converted into an above-grade, adjoining, ended up, warmed, 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 locations are thought about part of the room from which they come down, so if that room is thought about part of GLA, so is the stair location. If the stair opening is bigger than the stairs, then only the stairs (treads and landings) are included in the GLA for the flooring from which the stairs come down.
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 instance, stairs descending from a 2nd level to the ground flooring are counted in the GLA of the 2nd level.
Any location below the staircase is consisted of in the square video of the floor to which the stairs come down. So the location underneath the staircase in our example is consisted of 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 is part of the GLA for the floor from which the stairs come down. If the opening is broader than the stairwell, then consist of only the area equal to the size of the stairs (in the GLA for the floor from which the stairs come down).
Are fireplaces included or left out 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 prevail in lots of locations. According to the meaning of GLA from the Appraisal Institute, attics are not usually included in the GLA. However, regional practices on this vary. In many locations, an attic's area can be included in the GLA as long as it is heated up and finished.
If there is a sloped ceiling in the attic, then the ANSI Z765-2021 standard states that you can just consist of the floor area where the ceiling determines 5 feet up. Furthermore, at least one-half of the finished floor location must have 7 feet of ceiling height.
Take Your Appraisals to the Next Level
Appraising is a crucial job requiring precision and attention to information. There are generally recognized measurement standards depending on the area in which you live. A few of the guidelines now need computer-generated sketches for appraisal reports.
