What is Gross Living Area (GLA) and How Do You Calculate It?
Knowing how to compute the Gross Living Area (GLA) of a residential or commercial property is a crucial part of creating the appraisal report and estimating the value of a home. This post strolls you through the actions on how to calculate GLA with self-confidence.
What is Gross Living Area (GLA)?
Real estate is measured after local 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 finished, habitable, above-grade home. Finished basements and attic areas are not usually consisted of in the GLA total. However, regional practices vary on this.
GLA is an important part of the valuation of a home or residential or commercial property. It is not the very same as total living area (TLA). Although the Appraisal Institute does not strictly specify TLA, it is generally taken to include any completed basement space, habitable attic areas, and even unattached device home units.
Why is it Important to Know the Exact GLA of a Home?

The livable, above-ground space in a domestic property is the part of the home that commands the best rate. The evaluation of the residential or commercial property is frequently a direct result of just how much of the residential or commercial property's space has this condition and will, in turn, directly effect insurance expenses and worth and, eventually sales rate.
Because of this, it is essential that the appraiser consist of every valid location in a GLA computation so that the residential or commercial property achieves its rightful sales rate, the mortgage loan provider knows the appropriate value, and the residential or commercial property is properly 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 on utilizing different definitions and estimations. In the United States, the American National Standards Institute (ANSI) just recently introduced ANSI Z765-2021 to document common requirements for appraisers.
Some companies, such as Fannie Mae, a leading source of mortgage funding in the United States, now need appraisers to utilize these requirements and provide a valuable summary file.
The ANSI home measurement standard has a few crucial elements:
- It uses to single-family housing. It does not apply to homes, apartments, or commercial residential or commercial property.
- It specifies Gross Living Area (GLA) and what to consist of or exclude from the calculation.
- Measurements are noted to the nearest inch or tenth of a foot and reported on a sketch or flooring strategy of the residential or commercial property. The final square video computation is to be reported to the closest entire square foot.
What Is Included in the GLA Calculation?
For a space to be included as GLA, it needs to comply with these 6 criteria:
It should be completed. It should consist of walls, floorings, and ceilings, completed with basic materials such as carpet, drywall, and so on. It needs to be above ground. Even an area simply 2 feet below ground counts as basement space and is left out. It has actually to be enclosed. It needs to have 4 walls. It needs to be contiguous. It needs to be connected to the remainder of the Gross Living Area. It should be conventionally heated, utilizing forced air, solar, radiant heating, and so on (area heaters do not count). It must be permitted. The regional city or county structure department need to have allowed the area. If an area meets all these components, include it in the GLA. Note that the external walls for consisted of areas are part of the measurement. A space is omitted from the GLA if any of the above criteria are unmet. Instead, it can be noted as a different line item in the report and included as part of the TLA.
What Are Non-GLA Areas in a Residential or commercial property?
As the GLA is the total of the above-ground property space of adjoining, ended up areas, it is necessary to comprehend which areas of a residential or commercial property are not consisted of in the GLA estimation. These locations are, nevertheless, often included in the estimation of TLA.
Examples of areas that are not included in the GLA computation are:
- Unfinished garages. - Below-grade (listed below ground level) rooms such as basements. This consists of walk-out basements - ones with direct access to the outside - normally discovered in a home developed on a slope. Instead, list them in the TLA.
- Finished outbuildings or structures not connected to the primary building, such as cottages or Accessory Dwelling Units (ADU). Instead, list them in the TLA.
- Finished locations that are only connected to the primary living space by an incomplete location - simply put, they are not linked by a completed and warmed corridor or staircase. For example, a visitor suite connected to the primary home by means of an unfinished garage. Instead, list them in the TLA.
- Finished living spaces where more than 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 need to be omitted from the GLA.
- Covered or discovered patios and decks.
- Porches that are not confined, or if confined, are not suitable for year-round usage. These are typically called three-season spaces.
- Openings in a level that look down to the floor 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 left out if it is surrounded on 3 sides by external walls.
- A space that was constructed or redesigned without a proper permit.
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 produce a digital sketch utilizing layout software on your tablet. Start measuring - work your method from corner to corner and use a measuring tape, roto wheel, or a laser to get the right measurements. Round your measurements to the nearest inch or the nearest 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 determine any locations that don't meet GLA standards. These areas must be listed as TLA. Do the mathematics - Add together all the areas that adhere to GLA requirements - this is the GLA. Then add up the areas that are non-GLA, and include these to your GLA area, which offers you your TLA. Bonus Tip! Use Software to Double-Check Your Calculation
Make an expert floor strategy sketch complete with measurements and annotations, and add this as part of your appraisal report. This provides complete transparency on how you pertained to your estimation and gives you the confidence you have reached the ideal number.
Pick floor strategy software like RoomSketcher, as here you get an in-built overall location calculator that you can use to verify your measurements. If everything matches up, then fantastic!

GLA vs. Total Living Area (TLA)
While GLA is the completed, connected, above-ground space in a residential home, Total Living Area (TLA) generally includes below-ground completed space and non-connected (or non-contiguous) space.
Total Living Area includes, for instance, completed basement area and different completed buildings such as homes and accessory house units. Additionally, heated, completed attic spaces would be included as long as over half the location has a ceiling height of 7 feet or more. When it comes to a slanted ceiling in the attic, only the area with a height of five feet or more is counted.
If you utilize floor plan software application like RoomSketcher to draw your professional floor strategy, you can establish any area to leave out, so the automatic estimation doesn't include this location.
GLA vs. Gross Building Area (GBA)
Whilst GLA is the standard for single-family homes, multi-family domestic homes with 2 to 4 units are typically determined utilizing Gross Building Area (GBA). Both GLA and GBA determine the completed areas of a building.
The main distinction is that below-grade living space is included in the Gross Building Area. Like GLA, GBA includes completed hallways, storage rooms, utility room, and interior staircases.
GLA vs. Gross Internal Area (GIA)
Gross Internal Area (GIA) is often used for commercial structures. The Gross Internal area (GIA) is the entire enclosed internal flooring area, determined to the inside face of the exterior walls.
This measurement can offer business structure leases an idea of the usable interior flooring location. The measurement includes any space utilized by internal walls or partitions, as well as hallways, restrooms, and storeroom. It might also include garages and basements.
GLA vs. Total Square Footage
There is no "main" meaning of total square video. Rather overall square video footage is utilized to explain the square video footage of a defined area. You could, for instance, report the total square footage of the garage, which would not indicate whether the garage was finished or contiguous with the home.
The GLA just includes above-grade, completed, contiguous areas of a home whilst the total square video includes other locations (that may not be living areas) as long as they have walls, ceilings, and floors.
Total Square Footage can consist of garages, workshops, incomplete storage locations, patios, outdoor patios - any area under the primary roof, in addition to removed structures like separate garages, visitor suites, or cabanas.

Frequently Asked Questions (FAQ):
Are external walls included in the GLA computation?
Mostly. A GLA computation includes the external walls for the spaces, areas, and staircase, which fulfill the GLA standard, so only the outside walls of those areas are consisted of.
Is a garage included in the Gross Living Area?
No, unless it has been allowed and converted into an above-grade, contiguous, ended up, warmed, habitable space.
Are closets included in Gross Living Area?
Generally, yes, if they meet the height requirements.
Are stairs included or omitted in GLA?
The stair treads and landing locations are thought about part of the space from which they descend, so if that space is considered part of GLA, so is the stair area. If the stair opening is bigger than the stairs, then only the stairs (treads and landings) are in the GLA for the floor from which the stairs come down.
How do you calculate 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 descending from a 2nd level to the ground floor are counted in the GLA of the second level.
Any area below the staircase is included in the square footage of the flooring to which the stairs descend. 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 same size as the stairs, then the entire opening is part of the GLA for the flooring from which the stairs descend. If the opening is wider than the stairwell, then consist of only the area equivalent to the size of the stairs (in the GLA for the flooring from which the stairs descend).
Are fireplaces included or omitted 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 definition of GLA from the Appraisal Institute, attics are not generally included in the GLA. However, regional practices on this differ. In many areas, an attic's area can be consisted of in the GLA as long as it is heated and finished.
If there is a sloped ceiling in the attic, then the ANSI Z765-2021 basic states that you can just include the floor location where the ceiling determines 5 feet up. Furthermore, at least half of the ended up floor location should have seven feet of ceiling height.
Take Your Appraisals to the Next Level
Appraising is a crucial job needing precision and attention to detail. There are normally acknowledged measurement standards depending on the area in which you live. A few of the standards now need computer-generated sketches for appraisal reports.
