Research notes
Not a preemption per se but the statutory skeleton that distinguishes DC zoning from every other US city: federal appointees sit on the local zoning body by statute. The two federal seats are non-removable by DC officials. Separately from the Zoning Commission, the Board of Zoning Adjustment (BZA) handles variances, special exceptions, and Zoning Administrator appeals.
