What Is Gross Living Area GLA And How Do You Calculate It
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 approximating the worth of a home. This short article walks you through the steps on how to determine GLA with confidence.
What is Gross Living Area (GLA)?
Real estate is determined after local regulations 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 area of completed, above-grade (in the air) residential area. It is calculated by measuring the outdoors border of the structure and includes just finished, habitable, above-grade home. Finished basements and attic areas are not generally consisted of in the GLA overall. However, local practices differ on this.
GLA is an important part of the assessment of a home or residential or commercial property. It is not the very same as overall living area (TLA). Although the Appraisal Institute does not strictly define TLA, it is typically taken to include any finished basement space, habitable attic locations, and even unattached device house systems.
Why is it Important to Know the Exact GLA of a Home?
The livable, above-ground space in a house is the part of the home that commands the best price. The assessment of the residential or commercial property is often a direct result of just how much of the residential or commercial property's space has this condition and will, in turn, straight effect insurance expenses and value and, eventually prices.
Because of this, it is essential that the appraiser consist of every legitimate location in a GLA computation so that the residential or commercial property accomplishes its rightful sales price, the mortgage lending institution understands the correct value, and the residential or commercial property is appropriately 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 the like utilizing different definitions and computations. In the United States, the American National Standards Institute (ANSI) just recently introduced ANSI Z765-2021 to record typical standards for appraisers.
Some companies, such as Fannie Mae, a leading source of mortgage financing in the United States, now require appraisers to utilize these requirements and supply a valuable introduction file.
The ANSI home measurement requirement has a couple of key components:
- It applies to single-family housing. It does not apply to apartment or condos, apartments, or business residential or commercial property.
- It specifies Gross Living Area (GLA) and what to consist of or leave out from the calculation.
- Measurements are noted to the nearest inch or tenth of a foot and reported on a sketch or layout of the residential or commercial property. The final square video footage computation is to be reported to the nearest entire square foot.
What Is Included in the GLA Calculation?
For an area to be included as GLA, it needs to comply with these 6 requirements:
It must be finished. It needs to contain walls, floors, and ceilings, finished with basic products such as carpet, drywall, and so on.
It should be above ground. Even an area simply 2 feet below ground counts as basement space and is omitted.
It needs to be enclosed. It should have 4 walls.
It needs to be adjoining. It should be linked to the rest of the Gross Living Area.
It needs to be conventionally heated up, utilizing forced air, solar, radiant heating, etc (area heating units do not count).
It should be allowed. The regional city or county building department must have allowed the area.
If an area fulfills all these aspects, include it in the GLA. Note that the external walls for included locations belong to the measurement. An area is omitted from the GLA if any of the above criteria are unmet. Instead, it can be noted as a different line product 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 very important to comprehend which areas of a residential or commercial property are not included in the GLA computation. These locations are, however, typically included in the estimation of TLA.
Examples of areas that are not consisted of in the GLA computation are:
- Unfinished garages.
- Below-grade (listed below ground level) rooms such as basements. This includes walk-out basements - ones with direct access to the outdoors - generally found in a home developed on a slope. Instead, list them in the TLA.
- Finished sheds or structures not connected to the primary structure, such as homes or Accessory Dwelling Units (ADU). Instead, list them in the TLA.
- Finished locations that are only connected to the main living area by an unfinished area - simply put, they are not linked by a finished and heated corridor or staircase. For example, a guest suite connected to the primary home through an unfinished 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 need to be left out from the GLA.
- Covered or uncovered patio areas and decks.
- Porches that are not confined, or if enclosed, are not suitable for year-round use. These are frequently called three-season spaces.
- Openings in a level that look down to the flooring listed below, such as a vestibule or foyer.
- Bump-outs that do not have a floor. For example, a cantilevered window-seat bump-out.
- A fireplace is omitted if it is surrounded on 3 sides by external walls.
- A room that was constructed or renovated without an appropriate authorization.
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 quick sketch of the residential or commercial property shape on paper or produce a digital sketch utilizing layout software application on your tablet.
Start determining - work your method from corner to corner and use 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 adhere to the ANSI standard.
Head inside - Ensure to go inside the residential or commercial property and determine any areas that don't meet GLA requirements. These locations should be noted as TLA.
Do the mathematics - Add together all the locations that abide by GLA requirements - this is the GLA. Then add up the areas 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 an expert layout sketch complete with measurements and annotations, and add this as part of your appraisal report. This gives complete transparency on how you came to your computation and gives you the self-confidence you have actually come to the best number.
Pick floor plan software application like RoomSketcher, as here you get an inbuilt total area calculator that you can utilize to double-check your measurements. If everything matches up, then excellent! If not, inspect that you have actually gotten in the exact same measurements into RoomSketcher as in your manual computations, and evaluate your manual for any errors or oversights.

GLA vs. Total Living Area (TLA)
While GLA is the ended up, connected, above-ground area in a house, Total Living Area (TLA) typically includes below-ground completed area and non-connected (or non-contiguous) space.
Total Living Area includes, for example, finished basement area and separate completed structures such as homes and accessory dwelling units. Additionally, heated, finished attic spaces would be consisted of as long as over half the location has a ceiling height of 7 feet or more. When it comes to an inclined ceiling in the attic, only the area with a height of 5 feet or more is counted.
If you utilize layout software like RoomSketcher to draw your expert flooring strategy, you can set up any area to omit, so the automated computation doesn't include this area.
GLA vs. Gross Building Area (GBA)
Whilst GLA is the standard for single-family homes, multi-family homes with two to four units are typically determined using Gross Building Area (GBA). Both GLA and GBA determine the ended up areas of a building.
The main difference is that below-grade living area is included in the Gross Building Area. Like GLA, GBA includes finished hallways, storeroom, laundry spaces, and interior staircases.
GLA vs. Gross Internal Area (GIA)
Gross Internal Area (GIA) is frequently used for industrial buildings. The Gross Internal area (GIA) is the whole enclosed internal floor area, determined to the within face of the outside walls.
This measurement can provide industrial building leases an idea of the functional interior floor area. The measurement includes any area utilized by internal walls or partitions, as well as corridors, toilets, and storage rooms. It may likewise consist of garages and basements.
GLA vs. Total Square Footage
There is no "official" definition of total square footage. Rather total square video footage is used to describe the square footage of a specified area. You could, for instance, report the total square footage of the garage, which would not show whether the garage was completed or adjoining with the home.
The GLA just consists of above-grade, finished, adjoining locations of a home whilst the total square video footage includes other locations (that might not be living spaces) as long as they have walls, ceilings, and floors.
Total Square Footage can include garages, workshops, incomplete storage areas, porches, patios - any location under the primary roofing system, as well as separated structures like different garages, guest 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 rooms, areas, and staircase, which satisfy the GLA standard, so just the outside walls of those locations 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, ended up, warmed, livable area.
Are closets included in Gross Living Area?
Generally, yes, if they fulfill the height requirements.
Are stairs consisted of or excluded in GLA?
The stair treads and landing areas are thought about part of the room from which they descend, so if that room is thought about 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 floor from which the stairs descend.
How do you determine stairs in Gross Living Area?
The stair tread and landings are included in the Gross Living Area for the level from which they descend. For example, stairs coming down from a second level to the ground flooring are counted in the GLA of the second level.
Any location beneath the staircase is included in the square video 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 floor.
Note that if the opening to a stairwell is the very same size as the stairs, then the entire opening belongs to the GLA for the flooring from which the stairs descend. If the opening is larger than the stairwell, then include just the area equal to the size of the stairs (in the GLA for the floor from which the stairs come down).
Are fireplaces consisted of 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 consisted of in the GLA?
Finished attics prevail in many locations. According to the meaning of GLA from the Appraisal Institute, attics are not normally consisted of in the GLA. However, local 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 completed.
If there is a sloped ceiling in the attic, then the ANSI Z765-2021 basic states that you can just include the flooring location where the ceiling measures five feet up. Furthermore, a minimum of one-half of the finished flooring location should have 7 feet of ceiling height.
Take Your Appraisals to the Next Level
Appraising is an important job requiring accuracy and attention to detail. There are normally acknowledged measurement standards depending upon the area in which you live. A few of the standards now require computer-generated sketches for appraisal reports.
