Understanding Gross Living Area (GLA) in Appraisals
Gross Living Area (GLA) is a crucial concept in property appraisals, as it directly impacts the value of a property. GLA refers to the total finished, above-grade residential space measured along the building’s outside perimeter. Understanding GLA is essential for buyers, sellers, real estate professionals, and appraisers to ensure accurate property valuations. In this blog post, we’ll delve into what GLA is, how it’s calculated, and why it matters in appraisals.
What is Gross Living Area (GLA)?
Gross Living Area (GLA) represents the total finished area of a home that is above ground. It includes all the habitable spaces that are finished, heated, and directly accessible from other living areas. GLA is typically measured from the exterior walls, capturing the full footprint of the living spaces.
How is GLA Calculated?
GLA is calculated by measuring the exterior dimensions of the home and accounting for all finished, above-grade living areas. Here are the key components included in GLA:
- Finished Rooms: All rooms that are finished, heated, and directly accessible, such as bedrooms, living rooms, kitchens, and bathrooms.
- Closets and Hallways: These spaces are included if they are part of the finished, heated living area.
- Attics and Basements: Only included if they are finished, heated, and above-grade. Unfinished or below-grade areas are not part of the GLA.
- Extensions and Additions: Any extensions or additions that meet the criteria of being finished, heated, and above-grade are included in the GLA.

Why GLA Matters in Appraisals
Understanding GLA is crucial for several reasons:
1. Accurate Property Valuation
GLA is a key factor in determining the market value of a property. Larger GLA typically indicates a higher property value, as it represents more livable space. Accurate measurement of GLA ensures that the property is valued correctly, benefiting both buyers and sellers.

2. Comparable Sales Analysis
Appraisers use comparable sales (comps) to determine a property’s value. Accurate GLA measurements allow for a fair comparison between properties. Inconsistent or incorrect GLA measurements can lead to inaccurate appraisals and misleading comparisons.

3. Legal and Financial Considerations
GLA impacts legal and financial aspects of a property transaction, including mortgage approval, property taxes, and insurance. Lenders require accurate GLA to ensure the property’s value justifies the loan amount. Incorrect GLA can lead to higher or lower property taxes and insurance premiums.
Common Misconceptions About GLA
Understanding what is and isn’t included in GLA helps clear up common misconceptions:
- Finished Basements: Generally not included in GLA unless they are fully above-grade and meet other criteria.
- Garages: Not included in GLA, even if they are finished.
- Porches and Decks: Not included in GLA unless they are fully enclosed, finished, heated, and directly accessible from other living areas.

Enhancing Your Property’s GLA
Homeowners looking to increase their property’s value can consider finishing additional areas of their home to enhance GLA. Converting attics, adding extensions, or finishing above-grade basements can contribute to a larger GLA and potentially higher property value.
