Zoning Boundaries (ZR16): District of Columbia Zoning Map Polygons

Zoning map polygons for the District of Columbia established under the Zoning Regulations of 2016 (ZR16), which superseded the 1958 regulations. The data is updated based on Zoning Commission text and map amendments, with a recent reorganization effective August 28, 2023.

Use Cases

• Available in multiple geospatial formats (GEOJSON, KML, WMS) for interoperability.
• Includes a documented update history, citing a major reorganization effective August 28, 2023.

Limitations
