Nationwide property zoning data can be accessed through Realie’s property API, which connects county parcel polygons with local municipal zoning ordinances and land-use codes across 3,100+ U.S. counties. Every record includes the local zoning code, zoning description, land-use classification, and issuing jurisdiction.
Because zoning is governed at the municipal and county level rather than by state or federal standards, acquiring nationwide zoning and land-use data requires harvesting local GIS feature layers and municipal zoning maps. Realie normalizes zoning classification codes alongside standard land-use codes (residential, commercial, industrial, agricultural, vacant) joined to parcel boundary polygons, allowing developers to query zoning data in sub-10 milliseconds.
It is critical to distinguish between zoning codes and land-use codes. Zoning is the regulatory classification governing what is legally permitted on a parcel (e.g., "R-1" for single-family residential or "C-2" for commercial). Land use describes what is physically built on the parcel today.
Realie provides both attributes joined to the parcel ID: the official municipal zoning code and description, alongside normalized county land-use codes.
Zoning data is accessible via the REST API, the CLI, and visually on the Realie Explore map (/explore), where parcels can be color-coded dynamically by zoning district or land-use category at zoom level 14+.
This allows users to perform instant visual spatial analysis or programmatically query zoning attributes for up to 100 parcels per request.
