Key Zoning Facts
Dupont Circle Zoning Overview
Dupont Circle is a historic, densely developed neighborhood in Ward 2 of Washington, DC, with a population of approximately 9,200–17,100 residents. Approximately 80% of housing units in Dupont Circle are multifamily, making it one of DC's most urban residential neighborhoods. The area is known as DC's historic LGBTQ+ center and contains two designated historic districts. A distinctive feature of Dupont Circle's zoning is that all Mixed-Use (MU) zones carry the unique /DC suffix — a designation found nowhere else in Washington, DC. Dupont Circle is a neighborhood of the District of Columbia — it does not have its own municipality or planning department.

Zoning Districts
Dupont Circle's zoning falls under DC's 2016 Zoning Regulations (ZR16), codified in Title 11 of the DC Municipal Regulations (DCMR). The neighborhood contains the following primary zone types:
- RA-2 — Residential Apartment (low-medium density). One of the primary residential zones in Dupont Circle, reflecting the neighborhood's predominantly multifamily character.
- RA-4 — Residential Apartment (medium-high density). Permits larger apartment buildings in portions of the neighborhood closer to the commercial corridors.
- MU zones with /DC suffix — All Mixed-Use zones in Dupont Circle carry the unique /DC suffix (e.g., MU-4/DC, MU-5A/DC). This suffix is specific to Dupont Circle and is not found in any other neighborhood in DC. The /DC suffix modifies certain use and development standards for the Dupont Circle area's commercial corridors, including Connecticut Avenue NW, 18th Street NW, and P Street NW.
The specific MU zone (MU-1 through MU-10) varies by block and corridor. For the precise zone and applicable /DC standards for 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 and lot width. For exact requirements for your property, contact DCOZ at (202) 671-3500 or consult Title 11 DCMR at dcregs.dc.gov.
The /DC Suffix: A Unique Zoning Feature
The /DC suffix on all Dupont Circle Mixed-Use zones is unique in Washington, DC — no other neighborhood's MU zones carry this designation. The suffix modifies how the standard MU zone provisions apply within the Dupont Circle area, reflecting the neighborhood's particular character and development history. If you own or are considering property on a commercial corridor in Dupont Circle, it is important to understand that your zone code will include the /DC suffix, and that this suffix affects applicable standards. Consult Title 11 DCMR (available at dcregs.dc.gov) or contact DCOZ at (202) 671-3500 to understand the full implications of the /DC suffix for your property.
Historic District Overlays
Dupont Circle contains two designated historic districts:
Dupont Circle Historic District
- Designated: 1976 (expanded 1984 and 2005)
- Period of Significance: 1875–1931
- Character: One of DC's earliest designated historic districts, encompassing Dupont Circle's late-Victorian and Edwardian residential and commercial development. The district includes Embassy Row, grand rowhouses, and early apartment buildings along Connecticut Avenue.
Strivers' Section Historic District
- Encompasses the area historically associated with DC's Black professional class in the early 20th century, located within the broader Dupont Circle area.
Properties within either historic district require review by the DC State Historic Preservation Office (DCSHPO) and the Historic Preservation Review Board (HPRB) for exterior alterations, additions, and demolitions. Verify whether your property is within a historic district boundary using DC Open Data at opendata.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 Dupont Circle, accessory apartments may be permitted in RA zones subject to size limits and occupancy requirements. Properties within a historic district may need additional design review for exterior modifications. Contact DCOZ at (202) 671-3500 for zone-specific ADU rules.
Development Process
Development in Dupont Circle — as throughout Washington, DC — requires working with DC-level agencies:
- Zoning Verification — Look up your property on the DC zoning map or contact DCOZ at (202) 671-3500 to confirm permitted uses, development standards, and the applicable /DC suffix provisions
- Historic Review (if applicable) — If your property is in the Dupont Circle or Strivers' Section Historic District, submit an application to DCSHPO/HPRB before any exterior work
- Building Permit — Apply through the DC Department of Buildings (DOB) at dob.dc.gov or in person at 1100 4th Street SW, Washington, DC 20024
