Washington, DC Building Safety: Building Permits (2026)

The District's building code makes it unlawful to erect, construct, reconstruct, convert, or alter any building or structure -- including interior renovations and remodels -- without first obtaining a building permit from the Director of the Department of Buildings. The Director must refuse the permit unless submitted plans fully conform to the applicable building regulations before work can start. Anyone who renovates, converts, or alters a building without the required permit, or in violation of the regulations, faces a fine of up to $100 per day for each day the violation continues, and the Corporation Counsel or an affected neighboring property owner can seek an injunction to stop the work.
