What Is an As-Built Survey and Why Is It Required for New Construction

You finish building. You’re ready to close out. Then the permit office puts a hold on your certificate of occupancy because you’re missing an as-built survey.
It happens more often than it should. An as-built survey is one of the final steps in any new construction project. It’s also the step developers most often underestimate.
Here’s what it is, what it covers and why it matters before you build another thing.
What Is an As-Built Survey?
An as-built survey is a document that records what was actually built on a property. A licensed land surveyor visits the site after construction is complete and measures the exact location of all improvements.
The finished drawing shows where structures sit on the lot, how far they are from property lines and where utilities, driveways and drainage features are located. It gets stamped by the surveyor and submitted to the permitting authority.
Some jurisdictions call it a “record survey” or a “final survey.” The name varies. The job is the same.
How It Differs From Other Surveys
Most surveys happen before or during construction. A boundary survey defines where the property lines are. A topographic surveyor maps the land’s elevation and existing features. A construction staking survey places markers on the ground so contractors know where to build.
An as-built survey is done after. It’s a verification tool, not a planning tool. It confirms that what was built matches the approved plans.
Why Is It Required for New Construction
Permit Closeout
Most local governments won’t issue a certificate of occupancy without an as-built survey. That document proves the structure was placed correctly on the lot.
Setback violations are a common problem. If a building sits too close to a property line or a utility easement, it shows up on the as-built. Catching that before someone moves in or opens for business is far better than catching it during a sale or a dispute.
Lender and Title Requirements
Many lenders require an as-built survey before releasing final funds on a construction loan. Title companies need it to confirm no encroachments exist before insuring the property.
If you built something that doesn’t match the approved plans, you have a problem with the bank before you have a problem with the county.
Future Ownership and Development
An as-built survey stays with the property. Future buyers, engineers and developers rely on it to understand what’s on the ground before they plan anything new.
If you plan to sell the project or develop adjacent parcels, an accurate as-built survey protects you from questions you don’t want to answer later.
What an As-Built Survey Covers
A licensed surveyor measures and records the following:
- Location of all structures on the lot
- Setback distances from buildings to property lines
- Driveways, parking areas and walkways
- Utility lines, meters and service connections
- Drainage features and retention areas
- Easements and any visible encroachments
The final drawing includes exact dimensions and the surveyor’s professional stamp.
Common Problems That Show Up
Setback Violations
A structure built too close to a property line or easement can delay occupancy. In some cases it requires a physical correction or a variance from local government.
Utility Conflicts
A utility line installed in the wrong location causes problems for maintenance crews and creates liability for the property owner.
Encroachments
Part of a structure crossing a property line creates a legal problem. Title companies won’t insure it. Banks won’t lend against it. Buyers won’t touch it.
When to Order an As-Built Survey
Order it before you need it. Don’t wait for the permit office to ask.
Talk to your surveyor early. Let them know an as-built will be required at the end of the project. Some surveyors will do a site check during construction to confirm placement before the final survey. That early step can prevent costly corrections.
Surveyors book up fast during peak construction seasons. Build enough lead time into your schedule.
Who Can Perform One?
Only a licensed land surveyor can perform and certify an as-built survey. An engineer or a contractor can’t sign off in place of a surveyor.
Verify the surveyor’s license before you hire. An unlicensed or improperly certified survey will be rejected by the permit office. You’ll lose time and pay for it twice.
Frequently Asked Questions
What is the difference between an as-built survey and a final survey?
They usually refer to the same thing. Different jurisdictions use different terms. Both documents record what was built on a property after construction is complete.
How long does an as-built survey take?
Most take one to three weeks from the site visit to the stamped drawing. Complex projects with multiple structures or underground utilities can take longer.
How much does an as-built survey cost?
Costs depend on the size and complexity of the project. Residential projects may start around $500. Larger commercial projects can run several thousand dollars. Get a written quote before work starts.
Can you start construction without an as-built survey?
Yes. The as-built happens after construction. You’ll need other surveys at the start of the project, such as a boundary survey or a construction staking survey. The as-built is the final step.
What happens if the as-built survey shows a problem?
It depends on what was found. Minor issues may be resolved with documentation. Setback violations or encroachments may require corrections to the structure or a variance from the local authority.
