View planning and zoning information for properties across the City of Boston on the Zoning Viewer. This interactive web-mapping application was designed to assist City staff and the public in locating and determining zoning information for Boston land parcels.

This data is updated on a monthly basis so the zoning information reported here may not reflect the most current legislation adopted by the Boston Zoning Commission.

The signed Code Maps, enacted by the Boston Zoning Commission and available at the offices of the Planning Department, together with any amendments, remain the official Zoning documents.  If discrepancies exist between the official print and Internet versions of the data, the official signed Code Maps shall be considered correct.  In addition to zoning districts and sub-districts, the City of Boston's zoning consists of 24 overlay districts reflected in this GIS layer.
