If you’ve ever ordered an appraisal, you’ve seen the term ‘GLA’ on your report.
\And when you compare that number to the square footage Zillow shows, you might notice a difference between the two measurements.
That comparison and misalignment often create confusion and frustration when trying to figure out your home’s market value.
In this post, we’re going to define GLA, show you what counts (and what it doesn’t), and share why appraisers rely on this measurement instead of total square footage.
Let’s break it down.
What Does GLA Mean in Real Estate?
In the real estate world, GLA stands for gross living area, but what exactly does that mean?
McKissock Learning defines gross living area as above-grade areas that are finished, heated, accessible, and meet minimum ceiling height requirements.
Let’s break down those criteria in more detail:
- Above-grade: the area must sit above ground level (most of the time, see our TAG tip below)
- Finished: walls, floors, and ceilings must look and feel like a livable space
- Heated: the space must have a permanent heating and cooling source (a plug-in unit does not count)
- Directly accessible: You must be able to reach the space from the main part of the home without going outside, unlike an ADU (accessory dwelling unit)
- Meets minimum ceiling height: Typically 7 feet in most of the room
TAG Tip: While McKissock’s definition of GLA excludes basements, garages, patios, and porches, it’s important to note that these determinations are made on a case-by-case basis.
If a home has a newly finished basement that has gone through the appropriate permitting, meets the above criteria, and is of equal quality and finish to the above-ground space, it can be valued as GLA. We talk through this more in our recent blog here.
What Gross Living Area Normally Includes, and What it Doesn't?
Below is a simple breakdown to help homeowners understand what counts towards GLA and what does not:
Included in GLA |
Bedrooms, living rooms, and dining areas |
Finished hallways, closets, and stairways above grade |
Bonus rooms that are finished |
Spaces accessed directly from the main part of the home |
Not Included in GLA |
Carports, sheds, or garages |
Sunrooms or porches without permanent HVAC |
Unfinished attics or crawlspaces |
Rooms only accessible from outside (like a room over a detached garage) |
TAG Tip: While GLA is one of the main measurements used to determine fair market value, buyer preference can play a significant role, too.
For example, a fully decked-out garage complete with high-quality shelving and an epoxy-coated floor might hold considerable value for the right buyer. In some cases, that space can contribute value similar to GLA, even though it doesn’t officially qualify as gross living area.
This is where your Realtor’s expertise comes into play when guiding your list price, negotiations, and helping you understand what today’s buyers truly care about.
GLA Scenarios in Brunswick
While these scenarios are hypothetical, they are based on real field experience from our appraisers in our coverage area, including Leland, Shallotte, and Southport in Brunswick County.
Example 1: Finished Room Over Garage in Leland | No permanent heat
A homeowner may have beautifully finished a room above the garage, but if it lacks a permanent heating and cooling system, it cannot be counted as GLA. Even if the space looks brand-new, portable headers or window units won’t qualify.
Example 2: Southport ‘Basement’ | Fully finished without Approval
True basements are rare in Southport because of the coastal water table, but we occasionally see lower-level spaces or walk-under areas that homeowners finish out. Even if the space looks great, it’s best to go through the proper permitting process to qualify as GLA. If it isn’t properly permitted, these spaces can still add value based on buyer preferences, though it may not qualify as GLA from an appraisal perspective.
Example 3: Glass Carolina Room in Shallotte | No HVAC
We often see stunning Carolina rooms with floor-to-ceiling windows. Without permanent HVAC access, though, they are not included in GLA. They can absolutely add appeal and value, but they don’t fall under gross living area parameters.
Example 4: Finished Bonus Room in Leland | Meets GLA criteria
On the flip side, a finished, heated above-grade bonus room that is directly accessible from the main home does qualify as GLA. When a room meets the requirement, we can confidently include it.
