The names below have logged 142 Google reviews between them, and a couple hold a perfect 5.0, which is rare in a trade where a single bad corner marker can sink a rating fast.

How we score

Every number on this page is computed from public Google data on the date shown, not from opinion or payment. Rating is the business’s live Google star average. Review volume is how many customers have rated them, ranked against other Seattle land surveyors. Confidence weighs the rating by that volume, so a 5.0 from dozens of reviews carries more weight than one from a handful. Recency reflects how recently customers are still leaving reviews. No business can pay to change these numbers.

How much does a land survey cost in Seattle? (2026)

Land survey pricing in Seattle depends heavily on lot size, terrain, and what kind of survey you need. One reviewer on this list mentioned a wellhead and reference-point survey coming in under a thousand dollars, well below a competing quote for the same job, but larger boundary, subdivision, or ALTA surveys run higher. Ask each firm for a written quote scoped to your property.

Serving Seattle and the Puget Sound

The surveyors above cover Seattle proper along with Bellevue, Renton, Tacoma, and the wider Puget Sound region, handling both residential lots and larger commercial and development sites.

What to ask before you hire a land surveyor

Are you licensed to survey in Washington State? (Ask for the license number.)
What type of survey do I actually need: boundary, topographic, ALTA/NSPS, or a boundary line adjustment?
What is your current lead time from booking to completed survey?
Will the survey be filed with the county, and do you handle that filing?
Is the quote flat-rate, and does it change if the property turns out to be more complex on-site?

Frequently asked questions

How did you choose these land surveyors?

We started from land surveyors in Seattle with a public Google presence, then ranked by rating, review volume, consistency, and recency. See How we score above.

Are these rankings paid?

No. Rankings come from the public Google data in the scorecard. A business can pay to be a Featured Partner, which adds a badge and top placement, but that never changes another business’s score or position on the underlying data.

How often is this updated?

The data carries a verified date (August 2026 on this page). We refresh listings periodically so ratings and review counts stay current.

What’s the difference between a boundary survey and an as-built survey?

A boundary survey establishes your legal property lines and corner markers, which is what you need before building a fence or resolving a dispute. An as-built survey documents the existing conditions of a structure, which is more useful for a remodel or addition. As Builts on this list specializes in the latter; most others here handle boundary work.

Do I need a survey filed with King County?

For subdivisions, boundary line adjustments, and many boundary disputes, yes. Several firms on this list, including SALISH GEO and True North, describe handling that filing directly, so ask upfront whether it’s included.

The bottom line

SALISH GEO is the safe default on sheer review strength for a straightforward boundary survey, while True North brings specific experience with Seattle’s boundary line adjustment process if your project needs that. Whoever you call, get the survey type and written quote confirmed before booking.
