Brookland Zoning Overview

Brookland is a residential neighborhood in Ward 5 of Washington, DC, with a population of approximately 9,600–21,000 residents. Known informally as "Little Rome" for its unusual concentration of Catholic institutions (including The Catholic University of America, Trinity Washington University, and numerous religious orders), Brookland is one of DC's most owner-occupied neighborhoods, with approximately 56% owner-occupied housing. The Brookland-CUA Metro station (Red Line) serves as a transit hub and has catalyzed mixed-use development along 12th Street NE and Monroe Street NE. Brookland is a neighborhood of the District of Columbia — it does not have its own municipality or planning department.

Zoning Districts

Brookland'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. The predominant zone in Brookland, covering the majority of residential blocks and reflecting the neighborhood's predominantly detached house character.
• 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). Found in portions of Brookland with attached rowhouse development. Permits single-family homes, two-family flats, and rowhouses.
• MU-4 — Mixed-Use (medium density). Applied along 12th Street NE and Monroe Street NE near the Brookland-CUA Metro station. Allows retail, office, and residential uses up to approximately 50 feet. This corridor has seen significant transit-oriented development including the Monroe Street Market project.

Note on setbacks: Setback requirements in DC are complex and vary by zone, lot width, and building type. For exact requirements for your property, contact DCOZ at (202) 671-3500 or consult Title 11 DCMR at dcregs.dc.gov.

Institutional Campus Zoning

Brookland contains several major institutional campuses — including The Catholic University of America and Trinity Washington University — which may have specific campus plan or institutional zoning designations. Before planning development adjacent to or involving these institutional properties, consult with DCOZ to understand applicable zone standards and any campus plan provisions.

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 Brookland, accessory apartments may be permitted in R-1-B, R-2, and RF-1 zones subject to size limits and occupancy requirements. Brookland's high proportion of owner-occupied single-family homes means many properties may be candidates for accessory apartment conversions. Contact DCOZ at (202) 671-3500 for zone-specific ADU rules.

Development Process

Development in Brookland — 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
• Brookland's ANC 5B provides community input on zoning and development applications
• Properties near institutional campuses (Catholic University, Trinity) should be aware of potential campus plan provisions
• The Brookland-CUA Metro corridor (MU-4 zone) is an active development area — review recent approvals through DC's permit portal
• Check for flood zones using FEMA's flood map service
• DC Open Data at opendata.dc.gov provides parcel-level data and permit history
