DC permits cost anywhere from $25 to several thousands of dollars depending on the type of permit you need.
Many simple permits have a flat fee. For example, a Home Occupation permit only costs $33 plus a 10% enhanced fee, for a total of $36.30.
Meanwhile, other permits are priced based on the square footage or the value of the construction. For example, a new construction permit costs $0.03 per cubic foot of construction, plus a 10% enhanced fee. As such, the cost of a permit for a new development depends on the size of the construction.

Types of DC building permits
Most jurisdictions organize their building permits into different categories, and Washington DC is no different.
The 4 main types of permits in DC are:
- Construction permits: The most common permit for the vast majority of construction projects, including new developments, additions, major alterations, and demolitions.
- Occupancy permits: Permits that certify a building or structure is safe to inhabit. You need an occupancy permit to prove that your structure adheres to zoning regulations, DC construction codes, and the Green Building Act.
- Trade and specialty permits: Permits for electrical, mechanical, plumbing, and gas projects. Also for projects involving antennas, boilers, and elevators.
- Public space permits: Permits to use or install structures on public spaces (the space between a building and the curb). Examples include front patios, sidewalk cafes, flag poles, dumpsters, and sidewalk repairs.
What is a DC occupancy permit?
An occupancy permit certifies that a building or structure is safe to live or work in. In DC, occupancy permits can be issued as a Certificate of Occupancy, a Certificate of Use, or a Home Occupation Permit.
There are 6 types of certificates of occupancy:
- Ownership change
- Use change
- Occupant load change
- Temporary occupancy
- New building
Note: As of October 2023, applicants must use the DOB’s digital platform, Certifi, to apply for a Certificate of Occupancy.
What is a DC postcard permit?
A DC postcard permit is a permit for common, small-scale construction projects that are limited to certain scopes of work as defined by the DOB. You can apply for and obtain a postcard permit online.
Postcard permits are generally intended for minor home improvement and small construction projects. They’re designed to be quick to obtain so that straightforward projects can be reviewed and approved as fast as possible.
DC permitting process overview
Navigate the DC permitting process in 6 steps:
- Learn about your property restrictions and status
- Determine the scope of your project
- Prepare and submit your application
- Plan review
- Pay and receive your permit
1. Learn about your property restrictions and status
Before applying for a permit, determine if any development restrictions apply to your proposed project.
First, determine if you’re located in a zoning overlay. Overlay districts have additional zoning regulations on top of the underlying district’s policies. Check with the DC Office of Zoning to determine your precise zoning district.
You should also learn more about the conditions of the area where you intend to build. For example, assess whether you’re in a historically designated area, a Flood Hazard Area, or another location with unique specifications.
2. Determine the scope of your project
By understanding the scope of your proposed work, you’ll be able to determine the type of permit you need, as well as the documentation you’ll need to provide when applying.
For example, exterior construction may require a surveyor’s plat, which is a scaled drawing of a lot.
Familiarizing yourself with the unique requirements of the permit you need will help expedite the process and prevent mistakes along the way.
3. Prepare and submit your application
The DOB provides different online portals for different permit applications.
For example, one- and two-family residential projects must apply using the DOB Permit Wizard. Meanwhile, commercial projects, solar, demolition, and after-hours permits must apply using the Citizen Access Portal.
Make sure you complete your application with as much detail as possible to avoid rejection.
After submitting your application, the DOB will pre-screen it to assess completeness and ensure it meets the basic requirements for a full plan review.
If the DOB finds errors during the pre-screening, you’ll have to revisit your application and resubmit.
5. Plan review
After a successful pre-screening, the DOB will fully review your application. Other agencies may get pulled in to review your plan as needed.
During this full plan review process, DOB representatives will carefully assess the details of your proposed project to ensure it is up to code. This process could take a few days, several weeks, or a couple months depending on the scope of the project.
6. Pay and receive your permit
Once your plan is approved, all you have to do is pay necessary fees and receive your permit. Payments can be made online, by check, or in person at designated locations.
Working with a DC permit expediter
Even though the DC DOB has simplified the permitting process by moving it online, applying for a permit is still a tedious and time-consuming hassle. To simplify the process, you may consider permitting services, such as hiring a DC permit expediter.
