Documents

Required documents

DOB permit application submitted through the DC Access online portal at dcra.dc.gov/page/dc-access-online for any shed exceeding the 200 sq ft exemption or requiring structural review.
Scaled site plan showing property lines, existing structures, alleys, and the proposed shed location, footprint, and dimensions — required to confirm DCMR Title 11 setback and lot occupancy compliance.
Floor plan and elevations showing shed dimensions, wall heights, roof pitch, door and window openings, and intended use.
Structural footing and framing details complying with DCMR Title 12 (2017 DC Building Code) requirements for accessory structures, including footing design and connection hardware.
Contractor DC license number and certificates of insurance (workers' compensation and general liability) for any licensed contractor performing the work.
HPRB Certificate of Appropriateness or HPO staff-level approval if the property is in a DC historic district and the shed is visible from a public right-of-way. Must be obtained before submitting the DOB permit application.
Manufacturer's installation instructions and specifications for prefabricated shed kits when applicable.
Trade drawings and load schedules for electrical, plumbing, or mechanical work if utilities are being added to the shed.

Timeline

Typical timing

Plan review: 10–20 business days (standard plan review); HPRB/HPO historic review 4–8 weeks and must precede the DOB application
Total cycle: 5–9 weeks from DOB application to final inspection for permitted sheds

HPRB/HPO Certificate of Appropriateness should be initiated first for properties in historic districts — it is a prerequisite for DOB acceptance. Sheds within the 200 sq ft exemption with no utility work can proceed after confirming DCMR Title 11 zoning setbacks, with no DOB plan review required.

Process

How the permit process works

Apply the 200-square-foot exemption as the first filter Under DC Construction Codes (DCMR Title 12), a one-story detached storage or tool shed at 200 square feet or less is generally exempt from the DOB building permit requirement. Sheds over 200 sq ft, multi-story structures, and any shed with utility work require a permit. Even exempt-sized sheds must comply with DCMR Title 11 zoning setbacks and lot occupancy limits.
Verify zoning placement using the DC Zoning Map Use the DC Zoning Map at maps.dcoz.dc.gov to identify your zoning district (R-1 through R-5 or MU-residential) and confirm accessory structure setbacks, height limits, and lot occupancy limits under DCMR Title 11. Rear-yard setback and lot occupancy rules vary by district — verify placement before ordering a prefab unit or pouring footings. Alleys in DC also affect rear-yard measurements.
Check historic district status and initiate HPRB/HPO review if required Check whether your property is in a DC historic district or is a designated landmark using the DC Historic Preservation Office map at planning.dc.gov/historic. DC historic districts include Georgetown, Capitol Hill, Dupont Circle, Kalorama, Adams Morgan, Anacostia, Strivers' Section, LeDroit Park, and others. If so, and the shed would be visible from a public way, contact the HPO at planning.dc.gov/historic to initiate the Certificate of Appropriateness or staff-level review — this must be completed before DOB will accept a building permit application for qualifying shed work.
Check HOA/RHA covenants Many DC neighborhoods — particularly Capitol Hill, Georgetown, Chevy Chase, and others developed under deed covenants — have RHA or HOA rules governing shed size, materials, and placement. Check your deed covenants or contact your homeowner or civic association before ordering or building the shed. HOA approval is a separate process from DOB permitting.
Identify utility scope and trade permit needs Decide whether the shed will have electrical, plumbing, or mechanical work. Each utility trade requires a separate DOB permit and inspection regardless of shed size. Plan for trade permits even when the shed itself is exempt from the DOB building permit.
Prepare plans and submit through the DC Access portal For permitted sheds, prepare a site plan, floor plan, elevations, and foundation details complying with DCMR Title 12 (2017 DC Building Code). Submit through the DC Access portal at dcra.dc.gov/page/dc-access-online. Include the contractor's DC license number, insurance certificates, and any HPRB/HPO approval documentation.
Pay fees, post the permit, and complete inspections After plan review approval, pay all fees through the DC Access portal. Post the permit on-site before beginning construction. Request required inspections through the DC Access portal or by calling DOB at (202) 442-4400. Typical shed permit inspections include a foundation/footing inspection and a final inspection. Trade inspections are scheduled separately.

Code basis

What Washington reviews against

DC Construction Codes DCMR Title 12, 2017 DC Building Code (based on 2015 IRC/IBC with DC amendments) — permit exemption threshold and structural requirements for accessory sheds; DC Zoning Regulations DCMR Title 11 (accessory structure setbacks, height limits, and lot occupancy limits by residential zone); DC Historic Preservation Review Board (HPRB) and Historic Preservation Office (HPO) review requirements under DC Code Title 6 for properties in designated historic districts.

What can go wrong

DC Department of Buildings can issue a stop-work order and require removal or correction of unpermitted shed construction that needed a permit.
A shed placed in a required setback or exceeding lot occupancy limits can be ordered removed through DC zoning enforcement.
After-the-fact DOB review can require exposing foundation elements for inspection, adding significant cost.
Unpermitted electrical work in a shed creates fire and shock hazards that go unverified without DOB trade inspections.
HPRB violations in DC historic districts require separate enforcement from the Historic Preservation Enforcement Program and can mandate restoration at the owner's expense.
DC law requires sellers to disclose unpermitted work in real estate transactions; failure to disclose creates legal liability and can delay or kill a sale.
Civil fines for unpermitted construction accumulate through the DC Office of Administrative Hearings (OAH) until the violation is resolved.

FAQ

Common Washington shed permit questions

Do I need a permit to build a shed in Washington, DC?

Usually not if the shed is 200 square feet or less. Under DC Construction Codes (DCMR Title 12), a one-story detached storage or tool shed with a floor area of 200 square feet or less is generally exempt from the DOB building permit requirement. Sheds over 200 sq ft and any shed with utility work require a permit. DC zoning setbacks and lot occupancy limits still apply to all sheds. And if your property is in a historic district, HPRB/HPO review is required regardless of shed size.

What is the largest shed I can build without a permit in Washington, DC?

DC's exemption threshold under DCMR Title 12 is 200 square feet for a one-story detached accessory structure. DC's threshold matches Massachusetts (200 sq ft) and is more permissive than California (120 sq ft) or Chicago (100 sq ft). Note: the building-permit exemption does not eliminate zoning compliance — DCMR Title 11 setbacks, height limits, and lot occupancy rules apply to all sheds. Verify using the DC Zoning Map at maps.dcoz.dc.gov.

Does my DC historic district require HPRB approval before I can build a shed?

Yes. If your property is in a designated DC historic district — Georgetown, Capitol Hill, Dupont Circle, Kalorama, Adams Morgan, Anacostia, LeDroit Park, or others — and the shed would be visible from a public right-of-way, you must obtain a Certificate of Appropriateness from the HPRB or Historic Preservation Office (HPO) before the DOB will accept your building permit application. This review is separate from and must precede the DOB permit process. Check your property at planning.dc.gov/historic.

Do HOA or RHA covenants affect my DC shed?

Frequently, yes. Many DC neighborhoods were developed under deed covenants enforced by Residential Home Associations (RHAs) or HOAs — Capitol Hill, Georgetown, and Chevy Chase are common examples. These covenants may restrict shed size, materials, placement, or appearance more strictly than DC code. Check your deed restrictions or contact your homeowner association before ordering a shed. HOA approval is a private process separate from DOB permitting.

Does adding electricity to my DC shed require a permit?

Yes. Adding wiring, outlets, lighting, or a subpanel to a shed requires a separate DOB electrical permit and inspection, even when the shed itself is 200 square feet or under and otherwise building-permit-exempt under DCMR Title 12.

How much does a shed permit cost in Washington, DC?

For a shed requiring DOB review, expect roughly $275–$650 in combined permit and plan review fees plus a $15–$25 technology surcharge. Sheds within the 200 sq ft exemption with no utility work incur no DOB building permit fee. Verify current amounts at dob.dc.gov.
