Super-power your analysis with Zoning Slices.

If you’re interested primarily in regulatory outcomes, Zoning Slices — each a unique geometric combination of base and overlay districts — may be what you’re looking for.

Our 150,000+ Zoning Slices are made using a two-step flattening procedure that collapses multiple overlapping districts districts into a single polygon — isolating the prevailing regulation across a host of zoning attributes: from residential treatments and parking requirements to height caps and minimum lot sizes.

The result is a dataset where every inch of land has exactly one set of governing rules, enabling advanced analysis and integration into data pipelines. You (or we) can combine Zoning Slices with your parcel data to produce tailored results, including site selection evaluations.

Zoning Slices are priced on a per-variable basis, with tiered pricing for standard variables and premium variables that we customize to meet your needs.

  • Information from zoned jurisdictions published to the National Zoning Atlas at the following scales:

    • Jurisdictions

    • Counties

    • Core-Based Statistical Areas (i.e., metropolitan and micropolitan areas)

    • States

    • The Zoning Slice: a unique geometric combination of base and any overlay district(s)

    • If you need us to join Slices to parcels and you don’t have parcel data, we suggest Regrid.

  • Zoning Slices can include one or many variables, including:

    • Residential use permissions (for 1-, 2-, 3-, and 4+-family housing, and accessory dwelling units)

    • Minimum lot size requirements (for 1-, 2-, 3-, and 4+-family housing)

    • Parking mandates and height caps

    • Treatment of specialized housing types, including:

      • Accessory dwelling units

      • Affordable housing

      • Planned residential developments

    Consult the Data Dictionary for a full list of options, including custom options.

    • GeoPackage, GeoJSON, or Geodatabase

    • Spatial join to your parcels (optional)
