How to find your house square footage by address
Your home’s square footage is on record — most people just don’t know where to look. The county assessor lists the finished (heated) living area used for your property taxes; the building permit and floor plans record the built area; and the parcel footprint shows the ground area under roof. We pull those together for your address and email you what the records show, with the source for each number.
What your free square footage report includes
Finished living area: the heated square footage the assessor uses for taxes
Year built & stories: from the county assessor record
Footprint / lot coverage: the ground area under roof, where mapped
Sources: which record each number came from, so you can verify it yourself
Coverage rolls out county by county — entering your address puts your county in the queue and processes your report as soon as it’s live.
Why homeowners look up their square footage
- Tax appeals: if the assessor has your square footage too high, you may be over-assessed and overpaying — check your property tax by address
- Listing accuracy: Zillow and listing sites are often wrong; the assessor record is what appraisers cite
- Renovation & flooring: know your real area before buying materials or getting quotes
- Refinance & appraisal: catch a wrong square footage before it drags your valuation
- Insurance: replacement-cost coverage is priced off square footage — wrong numbers cost you
Frequently asked questions
How do I find the square footage of my house by address?
Enter your address and email above and we’ll pull your county’s assessor record for free. Doing it yourself: look up your parcel on the county assessor’s property search — the “finished area” or “living area” field is the square footage used for your taxes.
Is the assessor’s square footage accurate?
It’s the number that matters most — it’s what your property taxes and most appraisals are based on — but it isn’t always right. Finished basements, additions, and converted garages are common sources of error. Our report shows the record so you can check it against reality and file a correction if it’s off.
Why is my square footage different on Zillow vs the county?
Listing sites pull from many sources and are frequently wrong or out of date. The county assessor record is the authoritative figure appraisers and tax offices use, which is why we report that one and cite it.
Does finished square footage include the garage or basement?
Usually not the garage, and unfinished basements are excluded from “finished living area.” A finished, heated basement may or may not count depending on your county’s rules. The report notes what’s included so the number is apples-to-apples.
Is this lookup really free?
Yes. Your square footage report is free — no credit card, no hidden fees, and we don’t sell your information to agents or contractors.
