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 vital part of developing the appraisal report and approximating the value of a home. This post walks you through the actions on how to calculate GLA with self-confidence.
What is Gross Living Area (GLA)?
Realty is determined after regional policies worldwide. In the US, Gross Living Area (GLA) is defined by the Appraisal Institute's Dictionary of Real Estate Appraisal, 7th Ed., as the total location of completed, above-grade (in the air) domestic space. It is computed by determining the outdoors border of the structure and includes only completed, habitable, above-grade home. Finished basements and attic locations are not typically consisted of in the GLA total. However, regional practices differ on this.
GLA is a critical part of the valuation of a home or residential or commercial property. It is not the same as total living location (TLA). Although the Appraisal Institute does not strictly define TLA, it is normally required to consist of any completed basement space, habitable attic locations, and even unattached device house systems.
Why is it Important to Know the Exact GLA of a Home?
The habitable, above-ground area in a home is the part of the home that commands the biggest rate. The assessment of the residential or commercial property is often a direct outcome of how much of the residential or commercial property's space has this condition and will, in turn, directly impact insurance expenses and value and, eventually list prices.
Because of this, it is essential that the appraiser consist of every legitimate area in a GLA calculation so that the residential or commercial property achieves its rightful sales price, the mortgage loan provider knows the proper worth, 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 computed, with appraisers, remodelers, and so on utilizing different definitions and computations. In the United States, the American National Standards Institute (ANSI) just recently introduced ANSI Z765-2021 to document typical requirements for appraisers.
Some companies, such as Fannie Mae, a leading source of mortgage funding in the United States, now need appraisers to use these standards and supply a handy overview document.
The ANSI home measurement requirement has a couple of crucial components:
- It applies to single-family housing. It does not apply to homes, condos, or business residential or commercial property.
- It defines Gross Living Area (GLA) and what to include or exclude from the calculation.
- Measurements are kept in mind to the nearest inch or tenth of a foot and reported on a sketch or floor strategy of the residential or commercial property. The final square video calculation is to be reported to the nearest whole square foot.
What Is Included in the GLA Calculation?
For an area to be consisted of as GLA, it needs to stick to these six requirements:
It should be completed. It should consist of walls, floorings, and ceilings, finished with standard materials such as carpet, drywall, and so on. It should be above ground. Even a space simply 2 ft below ground counts as basement space and is omitted. It has to be enclosed. It needs to have four walls. It needs to be adjoining. It needs to be connected to the rest of the Gross Living Area. It must be traditionally heated up, using forced air, solar, radiant heat, and so on (area heating units do not count). It must be permitted. The regional city or county building department must have allowed the area. If an area fulfills all these components, include it in the GLA. Note that the external walls for consisted of areas become part of the measurement. A space is omitted from the GLA if any of the above requirements are unmet. Instead, it can be kept in mind as a different line item 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 contiguous, completed locations, it is very important to comprehend which locations of a residential or commercial property are not consisted of in the GLA computation. These locations are, however, frequently included in the computation 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 outdoors - normally found in a home built on a slope. Instead, list them in the TLA.
- Finished outbuildings or structures not linked to the main building, such as homes or Accessory Dwelling Units (ADU). Instead, list them in the TLA.
- Finished locations that are just linked to the primary home by an incomplete location - to put it simply, they are not linked by a completed and heated corridor or staircase. For instance, a guest suite attached to the primary home by means of 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 area with less than a 5-foot ceiling height should be omitted from the GLA.
- Covered or uncovered patios and decks.
- Porches that are not enclosed, or if confined, are not appropriate for year-round usage. These are often 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 floor. For instance, 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 built or remodeled without a suitable license.
5 Practical Tips on How to Measure GLA On-Site
Start with a walkaround - Walk the exterior of 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 fast sketch of the residential or commercial property shape on paper or develop a digital sketch utilizing flooring plan software application on your tablet. Start measuring - work your method from corner to corner and utilize a measuring tape, roto wheel, or a laser to get the correct measurements. Round your measurements to the closest inch or the nearby 1/10th of a foot so you adhere to the ANSI requirement. Head inside - Make certain to go inside the residential or commercial property and determine any locations that do not meet GLA standards. These areas should be noted as TLA. Do the mathematics - Total all the locations that abide by GLA requirements - this is the GLA. Then include up the locations that are non-GLA, and add these to your GLA area, which gives you your TLA. Bonus Tip! Use Software to Double-Check Your Calculation
Make a professional flooring plan sketch total with measurements and annotations, and add this as part of your appraisal report. This offers total transparency on how you came to your estimation and gives you the you have gotten to the right number.
Pick floor plan software like RoomSketcher, as here you get an inbuilt total area calculator that you can utilize to confirm your measurements. If everything matches up, then fantastic! If not, inspect that you have actually gotten in the same measurements into RoomSketcher as in your manual estimations, and evaluate your manual computations for any errors or oversights.

GLA vs. Total Living Area (TLA)
While GLA is the finished, connected, above-ground area in a domestic home, Total Living Area (TLA) generally includes below-ground completed area and non-connected (or non-contiguous) area.
Total Living Area consists of, for instance, finished basement area and separate finished buildings such as cottages and accessory home systems. Additionally, heated, completed attic spaces would be included as long as more than half the area has a ceiling height of seven feet or more. When it comes to a slanted ceiling in the attic, just the location with a height of five feet or more is counted.
If you use layout software like RoomSketcher to draw your expert layout, you can set up any area to leave out, so the automatic estimation does not include this location.
GLA vs. Gross Building Area (GBA)
Whilst GLA is the requirement for single-family homes, multi-family homes with 2 to four units are typically determined utilizing Gross Building Area (GBA). Both GLA and GBA determine the ended up locations of a structure.
The main distinction is that below-grade living area is included in the Gross Building Area. Like GLA, GBA consists of ended up corridors, storage rooms, utility room, and interior staircases.
GLA vs. Gross Internal Area (GIA)
Gross Internal Area (GIA) is often used for industrial structures. The Gross Internal location (GIA) is the entire enclosed internal flooring space, measured to the inside face of the exterior walls.
This measurement can provide commercial building rents a concept of the functional interior flooring location. The measurement includes any space utilized by internal walls or partitions, in addition to hallways, restrooms, and storeroom. It might also include garages and basements.
GLA vs. Total Square Footage
There is no "official" meaning of total square video. Rather total square video is utilized to explain the square video footage of a specified area. You could, for example, report the total square video of the garage, which would not indicate whether the garage was completed or adjoining with the home.
The GLA just consists of above-grade, ended up, adjoining 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 floors.
Total Square Footage can consist of garages, workshops, incomplete storage areas, decks, outdoor patios - any area under the main roofing system, in addition to removed structures like separate garages, guest suites, or cabanas.

Frequently Asked Questions (FAQ):
Are external walls included in the GLA calculation?
Mostly. A GLA estimation includes the external walls for the rooms, locations, and staircase, which fulfill the GLA standard, so only the exterior walls of those areas are consisted of.
Is a garage included in the Gross Living Area?
No, unless it has actually been permitted and transformed into an above-grade, adjoining, ended up, heated, habitable area.
Are closets included in Gross Living Area?
Generally, yes, if they satisfy the height requirements.
Are stairs consisted of or left out in GLA?
The stair treads and landing locations are thought about part of the space from which they descend, 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 consisted of in the GLA for the flooring from which the stairs descend.
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 descend. For example, stairs coming down from a second level to the ground floor are counted in the GLA of the second level.
Any area below the staircase is consisted of in the square video footage of the floor to which the stairs descend. So the location beneath 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 belongs to the GLA for the floor from which the stairs descend. If the opening is broader than the stairwell, then consist of just the location equivalent to the size of the stairs (in the GLA for the flooring from which the stairs come down).
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 consisted of in the GLA?
Finished attics prevail in many areas. 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 areas, an attic's area can be included in the GLA as long as it is heated up and ended up.
If there is a sloped ceiling in the attic, then the ANSI Z765-2021 standard states that you can only include the floor location where the ceiling determines five feet up. Furthermore, at least one-half of the ended up flooring area must have seven feet of ceiling height.
Take Your Appraisals to the Next Level
Appraising is an essential job needing accuracy and attention to information. There are generally acknowledged measurement standards depending upon the area in which you live. A few of the guidelines now require computer-generated sketches for appraisal reports.
