Brightwood Zoning Overview

Brightwood is a residential neighborhood in Ward 4 of Washington, DC, with a population of approximately 9,000–16,000 residents. The neighborhood features a mix of building types: detached single-family homes are more common in the western portions, while rowhouses characterize the eastern blocks. The Georgia Avenue NW commercial corridor runs through the neighborhood, and the former Walter Reed Army Medical Center campus occupies a significant site at its northern edge. Brightwood is a neighborhood of the District of Columbia — it does not have its own municipality or planning department.

Zoning Districts

Brightwood'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:

• R-1-B — Low-density single-family detached residential zone. Predominant in the western portion of Brightwood, reflecting the neighborhood's detached house character on larger lots.
• R-2 — Semi-detached and duplex residential zone. Permits two-family semi-detached homes and duplexes in addition to single-family uses.
• RF-1 — Residential Flat (rowhouse/flat zone). Common in the eastern portions of Brightwood where the building fabric transitions to attached rowhouses. Permits single-family homes, two-family flats, and rowhouses.
• MU-4 — Mixed-Use (medium density). Applied along Georgia Avenue NW, Brightwood's primary commercial corridor, allowing retail, office, and residential uses up to approximately 50 feet in height.
• WR — Walter Reed Special Purpose Zone. Governs redevelopment of the former Walter Reed Army Medical Center campus at the northern edge of the neighborhood. This large former federal campus is subject to a specific approved development plan covering mixed-use, housing, and community facilities.

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 rowhouse zones (RF-1), front setbacks are often governed by the existing building line. For exact requirements for your property, contact DCOZ at (202) 671-3500 or consult Title 11 DCMR at dcregs.dc.gov.

Walter Reed Special Purpose Zone

The former Walter Reed Army Medical Center campus — a large federal installation that closed in 2011 — is being redeveloped under the WR (Walter Reed) Special Purpose Zone. This zone was created to guide the mixed-income, mixed-use redevelopment of the campus, which includes housing, retail, community facilities, a hospital (Children's National), and open space. Properties within the WR zone are subject to a specific development plan and design standards. For details, consult Title 11 DCMR Subtitle E or contact DCOZ at (202) 671-3500.

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 Brightwood, accessory apartments may be permitted in RF-1 and R-2 zones subject to size limits and occupancy requirements. Contact DCOZ at (202) 671-3500 for zone-specific ADU rules.

Development Process

Development in Brightwood — as throughout Washington, DC — requires working with DC-level agencies:

1. Zoning Verification — Look up your property on the DC zoning map or contact DCOZ at (202) 671-3500 to confirm permitted uses and development standards
2. 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
3. Board of Zoning Adjustment (BZA) — For variances or special exceptions, apply to the BZA through DCOZ
4. Zoning Commission — Map amendments (rezonings) are heard by the DC Zoning Commission
5. Inspections and Certificate of Occupancy — Schedule inspections through DOB and obtain a Certificate of Occupancy before use

Key Considerations

• Use the DC zoning map to verify your property's zone before planning any project
• Brightwood's ANC 4B provides community input on zoning and development applications
• Properties adjacent to or within the Walter Reed redevelopment campus should review the WR Special Purpose Zone provisions carefully
• Check for flood zones using FEMA's flood map service
• DC Open Data at opendata.dc.gov provides parcel-level data and permit history
