D.C. Code § 42-1901.05
No zoning or other land use ordinance or regulation shall prohibit condominiums as such by reason of the form of ownership inherent therein. Neither shall any condominium be treated differently by any zoning or other land use ordinance or regulation which would permit a physically identical project or development under a different form of ownership. No subdivision ordinance or regulation shall apply to any condominium or to any subdivision of any convertible land, convertible space, or unit unless such ordinance or regulation is by its express terms made applicable thereto. Nothing in this section shall be construed to permit application of any provision of the building code which is not expressly applicable to condominiums by reason of the form of ownership inherent therein to a condominium in a manner different from the manner in which such provision is applied to other buildings of similar physical form and nature of occupancy.
