How much does a lot line adjustment permit cost in Washington DC in 2026

Most property owners pay $400 – $1,500 for a lot line adjustment in Washington DC in 2026, with the total driven by plat review, surveyor recordation fees, and whether any structures or fences straddle the moved boundary and trigger a DOB building permit.

A lot line adjustment shifts the boundary between two adjoining parcels. It is a recording and survey exercise more than a construction one — which is why it is usually cheaper than a full subdivision. But it is not free, and the survey work behind it is the biggest wildcard in the budget.

Cost breakdown (2026)

Fee component	Typical 2026 cost
Application / plat review fee	$250 – $800
Surveyor recordation / plat filing	$100 – $300
Professional boundary survey (supporting)	$400 – $1,200
DOB building permit (if structures move/addressed)	$150 – $400
Technology fee (10%)	~10% of DOB permit fee
Enhancement fee (6%)	~6% of DOB permit fee
Zoning review (where applicable)	$0 – $250
Typical total (excluding survey)	$400 – $1,500

If your adjustment creates a new buildable lot, you have effectively subdivided — see DC subdivision permit costs. If it creates a nonconforming lot or setback, you may need relief — see DC zoning variance costs.

What affects the price

• Complexity of the boundary. A clean rectangle swap is cheap; irregular lots, alleys, or unrecorded easements add survey time.
• Whether the lot becomes nonconforming. A new nonconformity can force a zoning review or a variance.
• Structures on the line. Fences, additions, or utilities crossing the old line may require a DOB permit and possibly relocation work.
• Historic district. Adjustments that affect a landmark or historic lot can trigger preservation review.
• Agency coordination. If the adjustment touches an alley or public space, other agencies get involved and add fees.
• Easements and covenants. Private easements or deed restrictions can require legal work before the line moves.
• Both owners’ consent. An adjustment between two parcels needs both owners to sign and record, which adds coordination time.
• Title updates. Lenders and title companies may require fresh title work after the new plat is recorded.

How the fee is calculated

The plat and recordation portion is priced by the surveyor/recorder schedule, while any accompanying construction permit uses the DOB formula:

1. Filing fee: roughly $32.
2. Base permit fee: tiered by declared construction value — roughly $148 for the first $1,000, then about $10 per additional $1,000. Minimum flat tiers run around $33 – $65.
3. 10% technology fee on the permit fee.
4. 6% enhancement fee on the permit fee.
5. Zoning fee where a zoning review applies.

In short: the construction side scales with declared value, while the survey, review, and recordation fees are largely fixed per filing.

The practical effect is that a lot line adjustment between two built lots is usually a paperwork-and-survey cost, not a construction cost. Only when structures, fences, or utilities actually cross the moved boundary does the DOB permit formula — and its 10% and 6% surcharges — become the dominant line in your budget.

Timeline & steps

1. Commission a boundary survey. Expect 1 – 3 weeks depending on records and field conditions.
2. Prepare and file the plat. Submit the adjustment plat with the application fee.
3. Review and record. Review typically takes 2 – 6 weeks; once approved, the new plat is recorded.
4. Update records. Deeds, tax records, and title should be updated to reflect the new boundary.
5. Pull any needed DOB permit. Only if structures or utilities are affected.

Common mistakes

• No pre-filing survey. Filing on old records invites rejection.
• Creating an accidental nonconformity. Check zoning before you move the line, not after.
• Forgetting the title and deed update. The recorded plat does not automatically fix your deed.
• Assuming it is just paperwork. Structures on the line can convert a cheap recording into a construction project.

FAQ

Is a lot line adjustment the same as a subdivision?

No. A lot line adjustment moves an existing boundary without creating an additional lot; a subdivision creates new lots and follows a heavier review process.

Do I need a surveyor?

In practice, yes. DC plat filings are prepared and sealed by a licensed surveyor, and the recording depends on that sealed plat.

Will it change my property taxes?

It can. Moving square footage or frontage between parcels changes assessed values, so taxes may shift after records update.

How long does approval take?

Plan on 2 – 6 weeks for review and recording, plus survey time if you start from scratch.

Does the 10% technology fee and 6% enhancement fee apply?

They apply to any DOB construction permit involved. The pure survey, review, and recordation fees are separate line items.
