As-built survey cost: as built survey price for permit closeout and certificate of occupancy

An as-built survey costs $700 to $2,500 in 2026 for the sealed, field-measured document a building department accepts at permit closeout. A foundation location certificate on a single structure runs $700 to $1,200, a full residential site as-built $900 to $1,800, and a commercial or utility closeout $1,500 to $2,500 and up with scope. If you have found prices of $9,000, $40,000 or six figures, you are reading quotes for as-built drawings, which is a different product with a different professional behind it. The distinction below is worth more than any price range on this page, because ordering the wrong one is how a $1,100 job turns into a $9,000 one.

Why as-built prices range from $400 to $100,000

Two unrelated deliverables share the name "as-built," and almost every cost guide blends them into one range.

The first is an as-built survey. A licensed land surveyor goes to the site, measures what was actually constructed, and produces a sealed drawing showing the structures, their distance to each property line, finished floor elevations, and utility locations, overlaid on the approved plan so deviations are visible. This is what a plans examiner means when the permit condition says "final as-built survey required prior to certificate of occupancy." It is boundary and elevation work, it carries a surveyor's seal, and it is priced in the high hundreds to low thousands.

The second is as-built documentation, sometimes called record drawings or as-built drawings: a 3D laser scan or BIM model of an existing building's interior, walls, ceilings, and mechanical, electrical and plumbing systems, produced for renovation design or facility management. That work is scanning and drafting rather than surveying, it is usually sold by architecture, engineering or reality-capture firms, and it is where the $2,500 to $40,000 and up figures come from. Industrial facilities with dense MEP systems go well past that.

Your building department almost never wants the second one. Read the permit condition literally: if it references setbacks, property lines, finished floor elevation, flood zone compliance or a foundation location, it is asking for a surveyor. If it references room dimensions, wall locations or existing mechanical systems, it is asking for a scan.

How much does an as-built survey cost?

These are 2026 US ranges for surveyor-sealed as-built work.

As-built scope	Typical 2026 cost	When it is ordered
Foundation location certificate, single structure	$700 - $1,200	After the foundation is poured, before framing starts
Residential site as-built, full lot	$900 - $1,800	Permit closeout or certificate of occupancy
Commercial site or utility as-built	$1,500 - $2,500+	Closeout, bond release, utility district acceptance
As-built with elevation certificate in a flood zone	Add $400 - $900	Any build in a FEMA special flood hazard area
Re-visit after a correction or field change	Billed hourly, roughly $150 - $250 per crew hour	When the first submission is rejected or work changes
As-built drawings, 3D scan of an existing building	$2,500 - $40,000+	Renovation design and facility management, not permits

Two things move a surveyor's as-built quote more than square footage. The first is whether a boundary survey of the parcel already exists and is recent. The as-built has to be tied to the property lines, so if nobody has established the boundary, the surveyor is doing a boundary survey and an as-built in one trip, and the quote reflects both. The second is elevations. A flat certification that a structure sits inside its setbacks is cheaper than one that also certifies finished floor elevation against a benchmark, which is what flood zone permits require.

Why is an as-built survey required for a certificate of occupancy?

Because an inspector's tape measure is not evidence and a field inspection cannot confirm a setback to the hundredth of a foot. Building departments generally require a final lot survey prepared by a licensed land surveyor with new buildings and additions, and final approval or the certificate of occupancy is withheld until that verification is provided. The survey confirms the finished structure meets required setbacks, finished floor elevations, and any flood zone conditions attached to the permit.

The economics are the point. The as-built is the last chance to catch an encroachment while it is still a paperwork problem. A garage two feet into a side setback discovered at closeout costs a variance application. The same garage discovered by the neighbor's surveyor three years later costs a lawsuit, and the buyer's title company will see it either way.

When do I need a foundation location certificate instead?

A foundation location certificate is an early-stage as-built, ordered as soon as the foundation is poured and before framing begins. It certifies that the foundation sits where the permit said it would: inside the setbacks, at the right elevation, on the right lot. It is the cheapest survey on a build and it prevents the most expensive mistake on a build.

Order it if any of these apply: the lot is tight against a setback, the site is in a flood zone with a required finished floor elevation, the permit explicitly conditions framing inspection on it, or a lender is releasing draws against construction progress. A foundation misplaced by a foot is a correction that costs a few thousand dollars while the concrete is the only thing built. Discovered at closeout, the same error means moving or partially demolishing a finished structure.

Is an as-built survey the same as a record drawing?

No, and the difference decides whether a reviewer will accept it. A record drawing is the contractor's own marked-up plan set, showing changes made in the field. It is useful, and it is not independent. An as-built survey is field-measured by a licensed surveyor who was not the one building the project, and it carries a seal. Permit offices, lenders and utility districts rely on the sealed version precisely because the party certifying it has no stake in the answer. If your contractor offers to hand you a marked-up set instead of ordering the survey, ask the permit desk in writing whether they will take it. Most will not.

How long does an as-built survey take?

Field work on a residential lot is usually a single half-day visit, with the sealed drawing delivered in one to two weeks. Foundation location certificates often turn around in days rather than weeks, which matters when framing crews are standing by and every day of delay is a day of carried labor. Commercial closeouts with utility inverts take longer because they need several visits as different systems are completed and backfilled.

The scheduling trap on new construction is treating the as-built as a closing task. By the time you order it, you have already scheduled a certificate of occupancy inspection, and the survey is on the critical path. Book the surveyor when you book the final inspection, not after it.

What does an as-built survey include?

• A sealed drawing overlaid on the approved site plan so deviations read at a glance
• Locations of all structures with measured distances to each property line
• Finished floor elevations and site grades where the permit requires them
• Driveways, walks, patios, pools, retaining walls and other site improvements
• Utility locations and, on commercial work, invert elevations of storm and sanitary structures
• Deviation notes wherever built work departs from the approved plan
• A format and sheet size your specific municipality accepts, which is not a universal standard

How to get a comparable as-built survey quote

As-built quotes are hard to compare because firms scope them differently, and the gaps are invisible until the reviewer rejects the submission. Send every firm the same four facts and the numbers become comparable.

One, the exact permit condition. Copy the wording from your permit or the reviewer's correction notice. "Final as-built survey" and "as-built survey with certified finished floor elevation" are different jobs at different prices.

Two, whether a boundary survey exists. If you have a recent sealed survey of the parcel, say so and offer a copy. It can take a meaningful amount off the quote. If you do not have one, a boundary survey is part of the job whether or not the quote says so.

Three, the flood zone status. If the property sits in a FEMA special flood hazard area, the as-built usually has to carry certified elevations, and you may separately need an elevation certificate. Ask for both in one mobilization rather than paying twice for the same trip.

Four, the deadline. Say when the certificate of occupancy inspection is scheduled. Availability, not price, is usually what decides which firm you should hire, and a firm that cannot make your date is not the cheap option no matter what the number says.

Then verify the seal. Every state licenses land surveyors individually, and an as-built sealed by someone whose license has lapsed or who is licensed in the wrong state is not a document your permit office will accept. Our guide to verifying a land surveyor license covers how to check a licensee in about two minutes on the state board's roster.

Who orders and pays for the as-built survey?

On residential new construction, the general contractor usually orders it and bills it through, but the obligation sits with whoever holds the permit, which is normally the owner. Read your construction contract before assuming: plenty of fixed-price residential contracts carve out survey costs as an owner allowance, and owners discover this at closeout. On commercial work the developer or the general contractor orders it, sometimes both, because the lender and the municipality may each want their own certification.

If the as-built is being ordered because a lender is releasing a construction draw, the lender frequently specifies its own requirements for the certification language. Get those in writing before the surveyor mobilizes. A second trip to add one certification line is a second mobilization fee. Closeout also means paperwork moving between the owner, the contractor and the subs on a deadline, so having a way to send the lien waivers out for signature the same day the sealed survey lands keeps the draw request from stalling on one missing signature.

Where the as-built fits in the survey sequence

On a ground-up build, the as-built is the last of three site surveys, and buying them separately is how budgets drift. A topographic survey maps the ground before the engineer designs. Construction staking puts the approved design onto the ground during the build. The as-built proves afterward that what got built matches what was approved. Many firms will price all three under one contract at less than the sum of three separate mobilizations, so ask for the bundled number even if you only authorize the first stage today.

If your project is a new house, the whole sequence with what each stage costs is set out in the land survey sequence to build a house. If the permit condition mentions a site plan rather than an as-built, that is a different document ordered at a different time, covered on site plan survey for a building permit.

Get as-built quotes from licensed surveyors

Describe the job once on the Surveyors.io homepage, including your permit condition wording and your certificate of occupancy date, and compare quotes from licensed surveyors. Each quote states scope and a crew date, so you are comparing the same as-built rather than three different ones. The full price list across every survey type is on the land survey cost guide, and the scope detail for this specific product is on the as-built survey page.
