- MU-5A — Mixed-use medium-high density zone along the 18th Street NW and Columbia Road NW commercial spine. Permits ground-floor retail, restaurants, bars, and offices with residential uses above. Maximum height approximately 65 feet (6 stories). This zone defines the neighborhood's entertainment district character.
- RA-2 — Residential Apartment (low-medium density). Found in interior residential blocks, permitting multi-family apartment buildings.
- RF-1 — Residential Flat (rowhouse/flat zone). The predominant residential zone covering Adams Morgan's historic rowhouse blocks. Permits single-family homes, two-family flats, and rowhouses.
For the precise zone applicable to any specific address, use the DC interactive zoning map or contact DCOZ at (202) 671-3500.
Note on setbacks: Setback requirements in DC are complex and vary by zone, lot width, and building type. In RF-1 zones, front setbacks are often governed by the existing building line (structures must align with neighboring buildings). For exact setback requirements for your property, contact DCOZ at (202) 671-3500 or consult Title 11 DCMR at dcregs.dc.gov.
Historic District Overlays
Adams Morgan contains four locally designated historic districts that impose additional review requirements on exterior alterations:
- Reed-Cooke Historic District (designated 1989)
- Kalorama Triangle Historic District (designated 2004)
- Washington Heights Historic District (designated 2006)
- Meridian Hill Historic District (designated 2014)
Properties within these districts require review by the DC State Historic Preservation Office (DCSHPO) and the Historic Preservation Review Board (HPRB) for exterior alterations, additions, and demolitions. Interior changes generally do not require historic review. Verify whether your property is within a historic district boundary using the DC Office of Planning's historic preservation resources at planning.dc.gov.
ADU Rules
DC permits accessory dwelling units (ADUs), referred to as "accessory apartments" in DC zoning regulations, in many residential zones under Title 11 DCMR. In Adams Morgan, accessory apartments are permitted in RF-1 and RA zones subject to size limits and occupancy requirements. Properties within historic district boundaries may need additional design review for exterior modifications associated with an ADU conversion. Contact DCOZ at (202) 671-3500 for zone-specific ADU rules.
Development Process
