Your project may require additional permits such as Supplemental Systems Installation (A/C, electric, plumbing, etc.) and Water or Sewer Excavation (pipe installation, water main connections, etc.) *Note: Only licensed DC contractors for the specific trade may apply for these permits.

A public space permit is required to use or install structures in public space—the area between the building or property line and the curb. Many front yards in the District are considered public spaces. Examples of work that requires public space permits include the following:

• Dumpsters in public space
• Sidewalk construction and repair
• Sidewalk cafes
• Front patios
• Flag poles, planter boxes, retaining walls, and fences in public space

The District Department of Transportation (DDOT) manages and oversees the use and occupancy of public space. Learn more about public space permits at DDOT's website.

Find out if development restrictions apply to your project. Learn your zoning district and if you are in a zoning overlay. Overlay districts set forth additional zoning regulations that are combined with the underlying zoning district. Other development restrictions are administered by other agencies, such as Historic Preservation, the National Capital Planning Commission, the U.S. Commission of Fine Arts, and other preliminary review organizations. For more information and a complete list of overlays, visit the DC Office of Zoning.

Are you within a historically designated area? Are you within a Flood Hazard Area or Special Flood Hazard designated area? Find this and other useful information about your property on Scout.

This will determine the type of permits and additional documents. For any exterior construction, a surveyor’s plat may be needed to detail all existing and proposed structures and must be drawn to scale. A building plat is a scaled drawing of a lot, showing lot lines and record dimensions. Plats that only consist of interior work, such as bathroom remodeling, are not required for jobs. To learn about DOB's permit and plan review timelines, please read this document.

For one- and two-family residential projects, use the DOB Permit Wizard online permit application.

For commercial projects, solar, demolition, raze and after-hours permits, use the Citizen Access Portal. The portal will allow applicants the ability to apply, pay and receive construction permits online. For commercial projects:

• Select Building and Request a Building Permit Shop Drawing Approval, or Surveyor Plat  
• Select your permit type. When you submit your permit application, ensure your scope matches the permit type (e.g. a one-story addition – addition, alteration, and repair). You can view all permit types and definitions to determine which permit matches your description.
• Complete all required * fields and confirm that information is accurate.
• Be sure to consult DOB's Building Permit Fee Schedule so you are aware of the cost(s) associated with the permitting process.
• When you have fully submitted your application, you will be notified whether your application has been accepted before the next steps.

When your application is received by DOB, it will be reviewed to ensure it is complete and that it meets the basic requirements for plan review. Pre-screen review occurs in different phases based on the type of plan review selected for your project.

Digital Walk-Through
For small-scale projects that would have previously been reviewed over the counter with paper plans, you must now complete the process completely online. With our Digital Walk-Through, all plans and supporting documents are now accepted through our ePlan review system ProjectDox for a completed review in 1 business day. This includes simultaneous DOB plan reviews and digital routing to select sister agencies (Historic Preservation, District Department of Energy and the Environment, and District Department of Transportation) saving you time and a trip to our office. DOB Plan Reviews Disciplines: Structural, Zoning, Fire, Elevator Mechanical/Plumbing, Electrical, Green and Energy.

ProjectDox Plan Review
ProjectDox is an online platform for electronic plan submission and plan review. This system allows the electronic submission of building plans and supporting documentation. ProjectDox eliminates the need for an applicant to submit multiple paper copies of project plans in conjunction with the DOB permit application. ProjectDox (ProjectDox-accepted) applications are more complex scopes of work that require more than 1 or 2 business days for review. When your application is ProjectDox-accepted, you will receive a separate email that includes a link for you to create a username and password to upload your plans and supporting documents to begin the review.

After plans are uploaded, they are pre-screened for the basic requirements and assigned to necessary plan review disciplines within DOB and applicable sister agencies. Please refer to the Plan Review section to learn about different plan review assignments and when they are required.

Other agency reviews may be required depending on your scope of work:

• DC Water- New water connections
• District Department of Transportation- For impact of the public alleys, sidewalks or streets
• Historic Preservation Review Board and Commission of Fine Arts- Properties located within a historically designated area or deemed an area commissioned by the fine arts. You can view PIVS to confirm your properties status
• Washington Metropolitan Area Transit Authority (WMATA)- WMATA must review and approve all construction projects adjacent to WMATA-owned properties in order to ensure that Metro facilities, operations and riders are not negatively impacted in the short or long term
• DC Health- All new construction and/or major renovations to a food establishment or hygiene facility
• Department of Energy and the Environment- Projects involving soil disturbance, flood plains and lead abatement
• Office of Planning

Once your plans are approved by all assigned plan review disciplines and applicable review agencies, you can complete payment and your permit(s) will be issued.

• For Walk-Through applications, you will receive an invoice of the permitting fees by our Issuance Counter to pay at our Cashier’s Office or to make the payment online to have your permit issued.
• For ProjectDox application, you will receive an email notification that final fees are ready for payment. You can make payment online, or take your invoice and pay at the Office of Tax and Revenue at 1101 4th Street SW.

**All check payments should be payable to DC Treasurer.

During the plan review process, reviews by other agencies may be required depending on your scope of work. While the process requires the usage of DOB's permitting and plan review platforms to manage the permitting process, each agency operates independently and has their own service level agreements and requirements. In some cases, these timelines differ from those of DOB.

While not exhaustive, examples of reviews by other agencies include:

• DC Water- New water connections
• District Department of Transportation- For impact of the public alleys, sidewalks or streets
• Historic Preservation Review Board and Commission of Fine Arts- Properties located within a historically designated area or deemed an area commissioned by the fine arts. You can view PIVS to confirm your properties status.
