U.S. City Open Data Census
Powered by Open Data Census
Land use zone boundaries and zoning categories for parcels contained. Zoning ordinances typically regulate land use and building dimension for built improvements made on all properties within a city’s borders. As such, zoning impacts many aspects of our communities and daily lives — from the location of your local supermarket (and what you can purchase there) to the size and height of your home.
Having access to the mapped zones (GIS shapefiles or GeoJSON files) of designated permitted land uses in your city can help empower a better understanding of the forces shaping your community. Alternatively, the data might be provided in tabular format with an attribute giving location, such as a parcel ID. Either way, descriptions of allowed uses for each zone must be publicly available, often in a separate zoning regulations document. (More info)
