Adjust property boundaries between neighbors without full subdivision. Faster than subdivision, simpler approval process. Perfect for resolving disputes, squaring off parcels, or adding usable land.
Start Lot Line AdjustmentA lot line adjustment (LLA) allows you to shift the boundary between two or more existing parcels without creating additional lots. Unlike subdivision, LLAs don't increase parcel count — they just relocate the line. This makes approval faster and cheaper than full subdivision.
Common uses: moving a fence line to match actual use, resolving boundary disputes with neighbors, consolidating awkward shapes into buildable rectangles, or adding land to one parcel for setback compliance. TerraVector coordinates the survey, application, and recording to get your new boundaries approved and recorded.
Both property owners agree to the new boundary location and sign authorization.
Licensed surveyor establishes existing lines and maps the proposed new boundary.
Submit application to county showing existing and proposed lot lines, acreages, and dimensions.
Planning department verifies no new lots are created and all parcels meet zoning minimums.
County approves LLA. Surveyor prepares final boundary line adjustment map for recording.
New legal descriptions recorded with county auditor. Title companies update ownership records.
Lot line adjustments typically cost $5,000–$12,000 including survey, application, engineering review, and recording. Simple adjustments between two urban lots run $5K–$8K. Complex rural adjustments with multiple parcels and easements cost $9K–$12K.
A lot line adjustment changes boundaries without creating new parcels. A subdivision creates additional lots. LLAs are faster (6–10 weeks vs 12–24 weeks), cheaper, and don't trigger full environmental review or public hearings.
Yes. All affected property owners must sign the application and approve the new boundary. If your neighbor refuses, you can't proceed with an LLA — you'd need to explore other options like purchasing additional land or seeking a variance.
No. LLAs cannot increase the number of parcels. Both the original and adjusted parcels must remain conforming (meet minimum lot size, setbacks, and zoning requirements). If you want to create new lots, you need a subdivision.
Most lot line adjustments are approved in 6–10 weeks from application submittal. Survey work takes 2–3 weeks. County review averages 4–6 weeks. Recording adds another week. Total timeline is typically 8–12 weeks from start to finish.
Existing easements (utilities, access, drainage) typically remain in place and must be shown on the LLA map. If the adjustment affects an easement, you may need consent from the easement holder or create a replacement easement.
Yes. The county assessor will recalculate each parcel's value based on new acreage and dimensions. The parcel gaining land will see taxes increase; the parcel losing land will see taxes decrease. Notify your lender if you have a mortgage — they may require title updates.
