Lot Line Adjustments in Utah. Move the Line, Not the Garage.
Boundary line adjustments, lot combinations, lot amendments and plat revisions, surveyed, described and set in the ground by licensed Utah surveyors. About 57 adjustment and combination jobs in our records since 2000, from Nephi and Mount Pleasant to Eureka, Santaquin and Price.
What Is a Lot Line Adjustment?
A lot line adjustment moves the shared line between two neighboring properties without creating a new lot. It’s how owners fix a garage or fence built over the line, trade a strip of ground, make room for an addition, or combine lots into one. We survey both properties, write the new legal descriptions (or an amended plat inside a subdivision), and set the new corners once it’s recorded.
Most start with a boundary survey of both properties, from $1,025 for a recorded lot.

Why Owners Adjust Lot Lines
The most common reasons we see across central Utah.
A building over the line
A garage, shed or fence that crosses the shared line. Moving the line can be simpler than moving the building.
Neighbors swapping ground
Two owners agree to straighten a jog or trade a strip so both lots work better.
Combining lots or parcels
Several lots or parcels merged into one, like three Eureka townsite lots combined in 2025.
Room for an addition
Shifting a line to meet setbacks before building a garage, addition or shop.
Lot amendments & plat revisions
Changing lot lines inside a recorded subdivision, which usually means amending the plat.
Rural boundary adjustments
Reconfiguring acreage between family members or neighbors, with new section-based descriptions.
From Survey to New Corners in the Ground
Six steps; the approval details vary by city and county.
Boundary survey
Locate both properties’ existing lines and corners, and the buildings and fences near them.
Agree on the new line
We show options on the survey; the owners pick the line that works for both.
Check the rules
Lot sizes, frontage and setbacks have to work for both lots under the city or county ordinance.
New descriptions or plat
We write new legal descriptions, or prepare an amended plat if the lots are in a recorded subdivision.
Approval & deeds
The city or county approves; the owners sign deeds or the amended plat, usually through a title company or attorney.
Record & set corners
Documents are recorded with the county, and we set the new corners in the ground.

What Makes an Adjustment Go Smoothly
Habits from decades of moving lines between neighbors.
Survey both lots first.
The line you’re moving has to be found before it can be moved. Both properties get surveyed, not just the one with the problem.
Check setbacks on both sides.
Fixing one owner’s garage can’t leave the other owner’s house too close to the new line.
Mind the mortgage.
If either lot has a loan, the lender may need to approve the change. Your title company can tell you.
Set the new corners.
A recorded adjustment with the old pins still in the ground invites the next dispute. We set the new corners when we’re done.

Lot Line Adjustment Questions, Answered.
What is a lot line adjustment?
Moving the shared line between two neighboring properties without creating a new lot. The total land stays the same; it's just divided differently between the two owners.
How is that different from a lot split?
A lot split creates a new lot. A lot line adjustment only moves a line between existing lots, so the number of lots stays the same.
Does the city or county have to approve it?
Usually. Utah cities and counties review lot line adjustments under their land use ordinances to make sure both lots still meet lot size, frontage and setback rules. In a recorded subdivision, the change is usually made with an amended plat.
How long does it take?
The survey and new descriptions usually take two to four weeks. City or county review and recording add time, which varies by jurisdiction.
How much does a lot line adjustment cost?
It starts with a boundary survey of both properties, from $1,025 for a recorded lot, and more for older lots or acreage. New descriptions or an amended plat are quoted by scope. City and recording fees are separate.
Do both owners have to agree?
Yes. Both owners sign the deeds or the amended plat. If you and your neighbor disagree about where the line is now, start with a boundary survey, and talk to an attorney about the dispute.
Can you combine my lots into one?
Yes. We've combined lots and parcels in Eureka, Nephi, Payson, Mount Pleasant and Price, with a new single legal description.
We’re licensed surveyors and engineers, not attorneys. Deeds, title and boundary disputes belong with a Utah real estate attorney or title company.
Need to Move a Line?
Send both parcel numbers and what you’re trying to fix or build. We’ll check the records, confirm what the city or county requires, and quote a fixed fee.
