Your property may be larger than the county records.
Before you sell or lease, know the size you are marketing. We measure the building from the exterior, compare the calculated area with the Assessor's record, and prepare the documentation to support a correction or clearly disclosed measured figure.

This is a preliminary records review—not a measurement, appraisal, or promise that additional square footage exists.
Already ready? Book and pay for your measurementOur proprietary verification process
More than a measurement. A correction-ready record.
TrueFootprint's proprietary verification process goes beyond the basic square-footage measurement typically performed as one part of an appraisal. The difference is scope: we reconcile exterior dimensions with county records, isolate discrepancies, document the calculation trail, and prepare a property-specific correction package for owner submission.
For a sale or lease, that documentation also gives the owner and real estate professional a defensible source for discussing the measured area, explaining a public-record discrepancy, and directing buyers or tenants to conduct their own verification.
Larger footprints generally have more exterior wall length, so the same measurement-method difference can produce a larger total square-footage change.

Why verify the record?
Do not leave marketable square footage undiscovered.
Buyers and tenants compare properties by size, and sale pricing is often discussed in dollars per square foot. If a home measures larger than the public record, documenting that difference before marketing can materially change how the property is presented and compared.
Larger homes often show a greater absolute difference because a larger footprint typically has more exterior wall length to measure.
Illustrative market context only. Assumes $600 per square foot. The relationship between measured area and price is not dollar-for-dollar, and no sale price, rent, appraisal result, county action, or value increase is guaranteed.

Know the potential before buyers or tenants see the listing.
At an illustrative $600 per square foot, only a few documented feet equal the service fee. These figures provide market context—not a promise of value, rent, appraisal results, or county approval.

The opportunity may grow with the footprint: larger buildings usually have more exterior wall length, which can increase the absolute area difference between measurement methods. Measuring before a sale or lease gives you time to resolve or clearly explain the discrepancy before it becomes a negotiation issue.
Before you list or lease
Market the property with a documented size—not an unexplained discrepancy.
County records are an important reference, but they are not the only source used in a transaction. A professional measurement gives owners and agents a documented basis for presenting the property while clearly identifying the source of the figure.
Support the size buyers compare.
If the measured building area is larger, your agent can evaluate whether and how to present it with the proper source, included-area explanation, and disclosures—before pricing, photography, appraisal, and negotiations.
Lease with clearer property information.
Documented measurements help you describe the space consistently across rental marketing, leasing conversations, and future property records.
Reduce late-stage surprises.
Identify differences before the buyer's appraisal or inspection so the listing can state the measurement source and invite independent verification from the start.
Transparent marketing matters. A measured figure should not be presented as an assessor figure. Clearly disclose the measurement source and any known difference from public records, and allow buyers to verify square footage through their own due diligence.
How it works
From booking to submission in three clear steps.
Choose your day
Select a preferred date and provide any gate codes, access instructions, or animal warnings.
We measure outside
Our team completes the exterior measurement in one day. No interior entry is required, but we need access to the full property perimeter.
You submit
You receive one organized package for county submission and for review with your agent before selling or leasing the property.
Clear expectations
We prepare your evidence. The Assessor makes the decision.
Our guarantee applies to the measurement result—not county approval or property value. If our completed measurement does not document at least 10 additional square feet versus the applicable county record, we refund 100% of your service fee. County acceptance of the corrected square footage and any resulting increase in market value are not guaranteed.
