If you're a contractor or builder working in Washington, DC, the Department of Buildings (DOB) handles all construction permits through a valuation-based fee system. DC's permitting process has unique complications — historic districts covering large swaths of the city, federal overlay zones, and Commission of Fine Arts review.

Special Requirements to Know About
Historic districts cover a huge portion of DC. Georgetown, Capitol Hill, Dupont Circle, and dozens of other neighborhoods are designated historic districts requiring design review.
The reduced historic permit fee is a silver lining. Properties in historic districts pay a flat $36.30 permit fee instead of the standard valuation-based calculation.
Federal overlay zones add another layer. Projects near the U.S. Capitol or major federal buildings may require Commission of Fine Arts review.
