Alaska As-Built Survey Guide

An Alaska as-built survey answers a different question than a boundary survey, and a different question again than the short location map a lender sometimes orders so the file can close. An as-built locates what is already on the ground — house, deck, well, septic, shop, driveway, fence — relative to lines, easements, and setbacks the surveyor is asked to show. A boundary or retracement survey is about where the legal lines and monuments are. The lender product is often the cheapest drawing that proves the collateral exists and is not obviously in a floodway or on the neighbor’s lot. Mixing those three jobs is how people buy a shed that sits in a section-line easement and call it “surveyed.”

This is educational, not surveying advice. Hire an Alaska-licensed professional land surveyor for the product you actually need. For line fights and missing monuments, start with the Alaska property boundary survey dispute guide. If the drawing shows a strip along a section line, read the Alaska section line easement article before you assume the fence is the law.

Alaska as-built survey versus a boundary survey

A boundary survey (often a retracement) recovers or re-establishes corners, ties to the recorded plat or the metes-and-bounds description, and reports conflicts. You want that when the deed is old, the monuments are gone, two plats disagree, or you plan to fence, subdivide, or build near a line. The product is about title geometry.

An as-built survey assumes someone already built something. The surveyor locates those improvements and shows them against the lines and easements in the assignment. Builders use as-builts after construction to prove the house landed where the plot plan said. Buyers use them when the listing photos show a shop, a cabin, or a driveway that looks closer to the trees than the plat would allow. Sellers use them when a prior owner “just added a lean-to” and nobody recorded a thing.

Those jobs can be combined in one field trip if you pay for both. They are not the same stamp. A drawing that only shows the house footprint in the middle of a schematic lot is not a boundary determination. A beautiful monumented boundary that never locates the septic or the well is not an as-built of the systems you will live with.

DNR’s Survey Section is the State’s in-house surveyor for department work. It issues survey instructions and reviews surveys that protect the State’s interest in land. It also functions as the platting authority in the Unorganized Borough. Inside organized boroughs — Mat-Su, FNSB, Kenai Peninsula, the Municipality of Anchorage — local platting rules apply. Copies of many State and BLM plats are in DNR’s land-records search. That archive is not a substitute for a current field survey of your improvements.

The survey a lender orders is often neither

Residential purchase files in Wasilla and elsewhere on the road system usually need some survey product. What the underwriter accepts is a program and investor question, not a statewide statute that says “every Alaska house gets a full as-built.”

Common lender drawings are location or mortgage surveys: a relatively quick field visit that shows the dwelling, obvious sheds, and maybe a driveway, with a disclaimer that it is not a boundary survey. Some files need an ALTA/NSPS land title survey because the title company or the investor wants table-A items — utilities, parking, exceptions plotted. That is a different scope and a different invoice. Some cash or portfolio deals close on an old plat and a walkthrough. That is a risk allocation, not a best practice on acreage.

Ask three questions in writing:

Is the surveyor giving a professional opinion of the boundary, or only locating improvements on an assumed line?
Will the product show easements of record the title commitment lists, including section-line and public-use reservations?
Will it locate the well, septic, and any structure you can see from the driveway, or only the house?

If the answer to (1) is “assumed lot lines from GIS,” you do not have a boundary survey. If the answer to (3) is “house only,” you do not have a useful as-built for a shop-house or a cabin-plus-outhouse parcel.

There is no honest statewide price for an Alaska as-built. Travel, tree cover, monument density, winter snow, and whether the surveyor must research two recording districts all move the number. Get a written scope from a licensed surveyor. Treat internet “average cost in Alaska” lists as fiction.

Encroachments the as-built is meant to catch

Encroachment means an improvement crosses a line or sits in an easement it does not belong in. Alaska residential files see the same patterns repeatedly:

A fence or rock wall that followed a dozer cut, not the plat
A shop, conex, or wood shed over the line or into a utility easement
A driveway that uses the neighbor’s lot or a dedicated right-of-way
A well or septic in a public easement or too close to a line for the next owner’s comfort
A deck or Arctic entry that was never on the plot plan
A cabin or dry dwelling that sits closer to a section line than the owner believed

An as-built that shows the problem before you remove the inspection contingency is useful. An as-built that arrives the week of funding is a delay. Title insurance often excepts matters a survey would show. Buying without a current drawing on a wooded Mat-Su or Kenai lot is how people inherit a handshake driveway.

If the surveyor finds an encroachment, the cure is not “the lender will ignore it.” Cures include moving the improvement, a recorded boundary-line agreement, an easement, a vacation process, or walking away. The boundary dispute guide covers the neighbor fight. The section line easement article covers the public strip that can exist even when no road was ever built.

How to order the right product on an Alaska purchase

Match the assignment to the land. A 1970s Wasilla subdivision lot with visible pins and no extra buildings may only need a location survey plus a careful title read. A five-acre parcel off a borough road with a shop, a second cabin, and a creek wants a retracement and an as-built of every structure and system. Remote or unorganized-borough land may need DNR platting context on top of the private survey.

Give the surveyor the title commitment, plat, legal description, and any old survey. Ask them to plot exceptions, not just the fee line. Walk the lot if you can and point at the extra greenhouse. Do not use a borough GIS printout as a survey.

If you are financing, tell the loan officer what you ordered. A winter Mat-Su survey is a calendar problem. Premier Mortgage (NMLS# 1168048) does not perform surveys, but a purchase loan still waits when the drawing and the appraisal disagree. Terms vary; approval is not guaranteed.

Frequently Asked Questions

Is an Alaska as-built survey the same as a mortgage location survey?

Usually not: an as-built is scoped to locate existing improvements against lines and easements, while a lender location or mortgage survey is often a shorter product that shows the house well enough to close. Ask the surveyor, in the proposal, which of those you are buying. If the proposal never mentions monuments or record easements, treat it as a location map.

Do I need a new as-built if the seller has a ten-year-old survey?

Only if the old drawing still matches the ground and the current title exceptions. A shop, deck, well, or driveway added later makes the old sheet stale. A new easement or a replat does the same. Have a licensed surveyor say whether they will recertify the old work or must resurvey.

Can a title policy replace a survey on wooded Alaska acreage?

A standard owner’s or lender’s policy typically excepts facts a survey would disclose. Title insurance is not a substitute for locating the septic or the section line. On tree-covered Mat-Su or Peninsula lots, the cheap path is often the expensive path after closing. Order the survey product that matches the risk, then ask title what endorsements exist for that survey.

Who hires the surveyor in an Alaska purchase?

Either party can: buyers often order the product they need to keep a contingency alive, and sellers sometimes pay when they already know the shop is close to a line. Put the obligation in the purchase agreement so the closing date and the field work share one calendar. The surveyor works for the client named in the contract, not for the MLS photo.
