A comprehensive guide answering the question: “Does a house’s square footage include the garage?” Learn about real estate standards, measurement practices, and what homeowners and buyers need to know before listing or purchasing a property.
| Aspect | Inclusion Status | Key Details |
|---|---|---|
| Standard Garages | No | Unfinished garages (attached or detached) are excluded from Gross Living Area (GLA) regardless of connection to main structure |
| Converted Garages | Potentially | Only if fully converted to climate-controlled living space, meets building codes, and is functionally equivalent to main living areas |
| Finished Garages | No | Even finished garages with matching interiors and HVAC are excluded from GLA |
| Marketing Listings | Sometimes | Some listings may ambiguously include garage space, but this violates ANSI standards |
| Appraisal Standards | No | ANSI guidelines explicitly exclude garages from finished square footage calculations |
| Detached Structures | No | Detached garages/units are never included in GLA and are classified separately as Gross Building Area (GBA) |
When buying or selling a home, one of the first things we look at is the square footage. It’s a key factor in determining a property’s value and usability. But here’s a question that often confuses both buyers and sellers: does a house’s square footage include the garage?
What Is House Square Footage?
To answer the main question, it’s important to understand what house square footage means in real estate.
Definition and Importance
In simple terms, square footage refers to the total area of a house measured in square feet. It’s a widely used metric in real estate for pricing, comparing, and marketing homes. Accurate square footage is essential because it influences:
- Home pricing: Larger homes typically command higher prices.
- Appraisals: Lenders use square footage to determine a property’s market value.
- Property taxes: Tax assessments are often based on the size of your home.
Knowing the correct square footage ensures transparency and reduces the risk of disputes between sellers and buyers.
How Square Footage Is Typically Measured
Measuring square footage may seem straightforward, but specific standards exist. Here’s a quick overview:
- Only “livable areas” are included. These are spaces designed for year-round use, such as bedrooms, kitchens, living rooms, and bathrooms.
- Unfinished spaces like basements, attics, or garages are typically excluded unless converted into livable areas.
- Measurements are taken wall-to-wall on the interior, accounting only for usable floor space.
Square footage doesn’t always include everything under the roof. But where does that leave the garage? Let’s explore.
Does a House Square Footage Include the Garage?
Short Answer: Usually Not, But There Are Exceptions
For most homes, the answer is simple: No, the garage is not included in the square footage. However, there are exceptions to this rule. Some factors, such as local real estate practices or whether the garage has been converted into a livable space, may lead to its inclusion.
In most cases, garages are excluded because they’re considered non-livable spaces. They’re not heated, cooled, or finished in the same way as typical living areas. Let’s unpack why this distinction matters.

Why Garages Are Usually Excluded
Livable vs. Non-Livable Space
In real estate, a key concept is “livable space.” This refers to areas that meet specific criteria:
- Conditioned space: The area must have heating, cooling, and insulation for year-round comfort.
- Finished interiors: Walls, ceilings, and floors must be completed with drywall, paint, and flooring.
- Intended for everyday living: Spaces like bedrooms, kitchens, and bathrooms fall into this category.
Garages typically fail to meet these criteria. Most garages are uninsulated, unheated, and used for storage or parking rather than living. This is why they are generally excluded from square footage calculations.
Industry Standards and Guidelines
The real estate industry has established standards for measuring homes to maintain consistency. One commonly used set of guidelines is the ANSI (American National Standards Institute) standards, which explicitly exclude unfinished spaces like garages. These standards help appraisers, agents, and buyers make fair property comparisons.
However, there are cases where garage space might be included. Let’s explore them next.
When Is Garage Space Included in the Square Footage?
Finished Garages
If a garage has been converted into a finished, livable area, it may be included in the square footage. To qualify, it must:
- Have finished walls, flooring, and ceilings.
- Be equipped with heating, cooling, and insulation.
- Meet minimum ceiling height requirements (often 7 feet or higher).
For example, a garage transformed into a family room, office, or guest suite would likely be part of the home’s square footage.
Local Real Estate Practices
Real estate agents or appraisers might include garage space in their calculations in some regions, even if it’s not finished. This is more common in areas where homes have large garages, and buyers consider them valuable.
If you’re buying or selling a home, it’s a good idea to consult with a local real estate professional to understand what’s typical in your area.
Marketing and Listing Strategies
Sometimes, sellers or agents will emphasize the total usable area of a home, including the garage, in their listings. While this can make the property seem more spacious, it’s important to read the fine print and clarify what’s included in the listed square footage.
Types of Garages and Their Treatment in Square Footage
Here’s a quick comparison of different garage types and whether they’re typically included in square footage:
Garage TypeTypically Included? Notes
Attached is the garage no. (unless finished/livable) , which may be included if converted into a living space.
Detached Garage Rarely Usually excluded, even if it’s large or finished.
Converted Garage Yes (if livable) Must meet livable space criteria to count toward square footage.
How to Measure Square Footage Accurately
Step-by-Step Guide
If you’re measuring your home’s square footage, here’s how to do it:
- Prepare your tools: Use a measuring tape, laser distance measurer, and a notepad or app for calculations.
- Measure each room: Measure the length and width of each room and multiply to find the area.
- Sum the totals: Add up the square footage of all livable spaces.
- Exclude non-livable areas: Skip garages, unfinished basements, and attics unless they meet livable space criteria.
Special Considerations for Garages
- If your garage is finished and livable, measure it like other rooms.
- For unfinished garages, measure their area separately for reference, but don’t include it in the total square footage.
Why It Matters: Pricing, Appraisals, and Comparisons
Impact on Home Value
Square footage plays a crucial role in determining a home’s price. Larger homes typically have a higher price per square foot, so including or excluding the garage can significantly impact the valuation.
Appraisal and Loan Implications
Lenders rely on accurate square footage for appraisals. Misrepresenting garage space could lead to discrepancies in loan approvals or property assessments.
Comparing Listings
When shopping for homes, make sure you’re comparing apples to apples. Ask for clarification on whether the listed square footage includes the garage, especially if the total size seems unusually large.
Frequently Asked Questions (FAQs)
- Does a house’s square footage include the garage if it’s attached?
- No, unless it’s finished and meets livable space criteria.
- What about a finished or converted garage?
- Yes, a finished garage can be included if it’s conditioned and designed for living.
- Are detached garages ever included?
- Rarely, as they are considered separate structures.
- How can I confirm what’s included in a listing’s square footage?
- Ask the seller or agent for details and consult a local real estate professional.
Conclusion
So, does a house’s square footage include the garage? In most cases, the answer is no. Garages are typically excluded unless they’ve been converted into livable spaces. Understanding these distinctions is crucial for accurate pricing, appraisals, and informed decision-making.
Whether buying, selling, or renovating, always clarify what’s included in square footage calculations and consult local experts for guidance.
