2026 GUIDE • WASHINGTON DC

How much does an after-hours permit cost in Washington DC in 2026

Most contractors pay $150 – $450 for an after-hours permit in Washington DC in 2026, with the total set by the length of the approved window, the scope of night or weekend work, and the District’s technology and enhancement surcharges.

An after-hours permit lets you work outside the standard construction hours the District enforces for noise control — typically 7:00 a.m. to 7:00 p.m. on weekdays. If your project is on a schedule that requires overnight pours, early-morning deliveries, or weekend work near occupied buildings, you need this approval in hand before crews start.

Cost breakdown (2026)

Fee component	Typical 2026 cost
Filing fee	$32
After-hours / noise-variance permit fee	$100 – $250
Base permit fee (tiered by construction value)	$33 – $150
Plan review (when routed to review)	$50 – $150
Technology fee (10%)	~10% of permit fee
Enhancement fee (6%)	~6% of permit fee
Typical total	$150 – $450

If the overnight work is tied to a larger job, the after-hours approval stacks on top of your base building permit. Treat it as an add-on fee, not a standalone one — see DC scaffold permit costs and crane permit costs for the related components.

What affects the price

• Duration of the window. A single overnight concrete pour costs far less than a standing approval that runs nightly for weeks. Chargeable windows are measured in days and hours.
• Declared construction value. Because the base permit fee is tiered by construction value, the same after-hours request on a larger job carries a higher base.
• Noise-sensitive locations. Work near residences, hospitals, or hotels draws closer review, and additional noise-mitigation conditions can extend the approval timeline.
• Expedited processing. DOB offers faster review for an added fee, often worth it when a concrete pour is locked to a schedule.
• Related agency add-ons. If night work occupies public space — a lane closure, a crane pick over the street — expect a separate public space or traffic control permit and fee.

How the fee is calculated

DOB uses a formula, not a flat rate. Under the DOB fee schedule (2026):

1. Filing fee: roughly $32, charged up front.
2. Base permit fee: tiered by declared construction value — roughly $148 for the first $1,000 of value, then approximately $10 per additional $1,000. Minimum flat tiers for very low-value work run around $33 – $65.
3. 10% technology fee: added on top of the permit fee.
4. 6% enhancement fee: also added on top.
5. Zoning fee: where a zoning review applies.

The percentage surcharges are the reason a $200 after-hours fee comes out closer to $232 before the filing fee. The key takeaway: fees scale with the declared construction value and the approved scope. Document the scope tightly and the numbers follow.

Timeline & steps

1. Confirm your base permit. After-hours approval is usually granted alongside or on top of an active DOB permit, not instead of one.
2. File via CitizenAccess. Submit the after-hours request through DOB’s CitizenAccess portal with the exact dates, hours, and work scope.
3. Review: simple single-pour requests can clear in 1 – 2 weeks; recurring nightly approvals typically take 2 – 4 weeks.
4. Notify neighbors where required. Some approvals carry a notice condition; missing it can void the permission on the night.
5. Work the window. Inspectors can visit after-hours sites. Keep the approval and the approved scope on site.

Common mistakes

• Assuming a building permit covers night work. It doesn’t. Standard permits assume standard hours; working outside them without approval can trigger a stop-work order.
• Requesting the whole project duration. Over-broad windows draw more scrutiny and cost more than the nights you actually need.
• Skipping the noise plan. Reviewers want to see mitigation — barriers, equipment limits, monitoring. A thin plan gets sent back.
• Forgetting the public-space layer. Night work that blocks a sidewalk, lane, or loading zone usually needs a separate permit.

FAQ

What are standard construction hours in DC?

The District typically restricts noisy construction to daytime weekday hours, generally 7:00 a.m. to 7:00 p.m. Work outside that window needs an after-hours approval. Confirm current limits with DOB before scheduling.

Can I get an after-hours permit for a single night?

Yes. Single-window requests are common for concrete pours and crane picks, and they are the cheapest form of approval because the fee tracks duration.

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

Yes. Both percentage surcharges apply on top of the base permit fee under the DOB fee schedule (2026). A $200 base effectively costs about $232 before the filing fee.

How far in advance should I file?

Build in at least two to four weeks for recurring approvals. If your schedule is fixed to a pour date, file early or pay for expedited review.

What happens if I work after hours without approval?

Unapproved after-hours work can draw complaints, inspection visits, and a stop-work order that halts the job — usually costing far more than the permit itself.
