Baltimore, MD zoning map & districts

Baltimore City's zoning is codified by TransForm Baltimore, the comprehensive rewrite of the city's 1971 zoning code adopted in 2017 and administered by the Department of Planning together with the Department of Housing and Community Development. The code replaced dozens of legacy districts with a streamlined set of residential, commercial, downtown, industrial, and transit-oriented districts explicitly designed to support mixed-use, walkable, and transit-served development, including form-based standards in several corridor and downtown districts.

A published summary is never the authority. The adopted ordinance and the city's official zoning map govern, and both change — verify the district and every standard on your parcel before you rely on it.

How zoning works in Baltimore

Developers should note Baltimore's Transit-Oriented Development (TOD) districts applied around Metro SubwayLink and Light RailLink stations, its Industrial Mixed-Use (IMU) districts that allow residential and commercial conversion of former industrial areas (e.g., parts of Remington and Woodberry), and that vacant/rowhouse-heavy blocks are frequently subject to Baltimore's separate vacant-building and land-bank programs in addition to standard zoning entitlements.
