Zoning Report
Baltimore, MD Zoning
Baltimore City’s zoning framework is organized through Article 32 of the City Code, with base districts, special purpose districts, and overlay districts layered onto the zoning map. The available sources show a modern code that relies heavily on use tables, conditional-use review by the Board of Municipal and Zoning Appeals (BMZA), and targeted overlay tools for waterfront, transit-oriented, campus, and mixed-use areas. The source set provided supports only a partial citywide analysis, so this report focuses on the districts, approvals, overlays, and procedures that were explicitly documented in the gathered materials.
