District of Columbia County, DC

How permitting works in Washington, D.C.

Since Washington, DC, has no independent county government, the "County" role is consolidated into the District's centralized operations. The District's Office of the Surveyor and the Department of Buildings fulfill all typical county duties, such as maintaining official land records, plats, and administering the Master Address Repository required for permit issuance.

The District government acts as the sole authority for code adoption and permit issuance.
