U Street Corridor Zoning Overview

The U Street Corridor — also known as Greater U Street or historically as Cardozo/Shaw — is a neighborhood in Ward 1 of Washington, DC. Centered along U Street NW and intersecting with 14th Street NW, it is one of Washington's premier nightlife and entertainment districts and one of the most historically significant African-American heritage districts in the country.

By 1920, U Street NW had become the heart of Washington's African-American cultural life — known as the "Black Broadway" — home to the famous Howard Theatre (620 T Street NW), jazz clubs featuring Duke Ellington (who was born nearby), and hundreds of Black-owned businesses, restaurants, and institutions. The neighborhood was largely built after the Civil War, with the Washington streetcar system in the 1880s spurring residential and commercial development.

U Street suffered devastating damage in the 1968 riots following the assassination of Dr. Martin Luther King Jr., and did not fully revitalize until after the U Street Metro station (Green Line) opened in 1991. Today it is a thriving entertainment district. The census-counted population was 4,572 in 2010 (an 87% increase from 2000), with dramatic demographic change through gentrification — the neighborhood has shifted from a predominantly African-American community to majority white non-Hispanic residents as of 2020.

Zoning Districts

The U Street Corridor's zoning falls under DC's 2016 Zoning Regulations (ZR16). Residential blocks are predominantly RF-1, with MU-4 and MU-10 along the commercial corridors:

• RF-1 (Residential Flat, Low Density) — The primary zone for residential blocks north and south of U Street NW and 14th Street NW. RF-1 permits rowhouses with up to two dwelling units per lot, maximum 40 feet. These blocks contain the neighborhood's historic rowhouse fabric.

• MU-4 (Mixed-Use, Medium Density) — Applied to commercial and mixed-use properties along U Street NW and 14th Street NW. MU-4 permits moderate-density mixed-use development up to approximately 50 feet, allowing retail, restaurants, offices, and residential. This has been the standard zone for much of the U Street commercial corridor.

• MU-10 (Mixed-Use, High Density) — Applied to specific large redevelopment sites. In 2024, the DC Zoning Commission approved rezoning the 1.9-acre government-owned block at 16th/17th/U/V Streets NW from MU-4 to MU-10. This enables a 10-story mixed-use building (approximately 175 total units, including affordable housing units) where previously only a 4-story structure was allowed. MU-10 allows substantially greater height and FAR than MU-4.

U Street Historic District

The U Street Historic District was designated as a DC local historic district in 1998, with a Period of Significance of 1862–1948. The Greater U Street Historic District expands this designation. The district recognizes the neighborhood's extraordinary significance as the center of African-American cultural life in Washington.

What the historic district means for property owners:

• Exterior alterations, new construction, and demolitions within the U Street Historic District require review by the DC Historic Preservation Review Board (HPRB)
• This applies to contributing structures within the historic district boundaries
• Interior alterations generally do not require HPRB review
• The Strivers' Section Historic District along Sixteenth Street NW is an adjacent historic district — check boundaries at planning.dc.gov
• Contact the DC Office of Historic Preservation at planning.dc.gov to confirm whether your property is within the district and whether it is a contributing structure

ADU Rules

DC permits accessory dwelling units (ADUs), referred to as "accessory apartments" in DC zoning regulations, under Title 11 DCMR. In the RF-1 zones of the U Street Corridor, up to two dwelling units per lot are permitted as principal uses. Critical note: Because the U Street Corridor is substantially within the U Street Historic District, any exterior alteration associated with an ADU conversion may require HPRB review. Contact DCOZ at (202) 671-3500 and the DC Office of Historic Preservation before proceeding.

Development Process

Development in the U Street Corridor follows the DC development process, with additional steps for historic district properties:

1. Zoning Verification — Look up your property on the DC zoning map or contact DCOZ at (202) 671-3500
2. Historic Preservation Review (if applicable) — For properties in the U Street Historic District, submit an application to the DC HPRB for exterior alterations before applying for a building permit
3. Building Permit — Apply through the DC Department of Buildings (DOB) at dob.dc.gov or in person at 1100 4th Street SW
4. Board of Zoning Adjustment (BZA) — For variances or special exceptions, apply through DCOZ
5. Zoning Commission — Map amendments (e.g., MU-4 to MU-10 rezonings) are heard by the DC Zoning Commission
6. ANC Review — ANC 1B and ANC 2B (Ward 1) provide community input on development applications
7. Inclusionary Zoning (IZ) — Larger projects on the corridor trigger IZ requirements for affordable units
8. Inspections and Certificate of Occupancy — Schedule inspections through DOB

Key Considerations

• The U Street Historic District (designated 1998) covers much of the neighborhood — exterior alterations require HPRB review
• The MU-4 to MU-10 rezoning at 16th/17th/U/V Streets NW (approved 2024) reflects active upzoning pressure on the corridor
• Residential blocks are predominantly RF-1; two-unit flat configurations are permitted by right
• U Street NW and 14th Street NW are major entertainment and dining corridors; expect ongoing development activity
• The U Street Metro station (Green Line) serves the corridor; transit-oriented development is a priority
• The neighborhood is in Ward 1; confirm your ANC at planning.dc.gov
• Check for flood zones using FEMA's flood map service
• DC Open Data at opendata.dc.gov provides parcel-level data and permit history
