ZoningSnap combines public and open data. We credit each source below. Layers come from many agencies, are updated on different schedules and may be out of date, incomplete or simplified. They are not official determinations; always confirm with the municipality.
Base map
Map data © OpenStreetMap contributors, available under the Open Database License (ODbL). Map tiles and style by OpenFreeMap, using OpenMapTiles.
Address search
Address suggestions come from the Photon geocoder by komoot, which is built on OpenStreetMap data (© OpenStreetMap contributors).
Zoning districts
From public county and municipal GIS layers and official municipal zoning maps. Where a town publishes its zoning map only as a document, we trace the district boundaries from that official map. District lines are approximate.
Zoning rules
District rules (uses, lot size, setbacks, height, coverage, parking) are summarized from each municipality's published zoning code. The adopted code text and the municipality's interpretation control.
Tax parcels and lot outlines
From public county and state tax parcel GIS layers. Lot outlines and sizes are approximate and are not a survey.
Flood zones
From the Federal Emergency Management Agency (FEMA) National Flood Hazard Layer. FEMA data is not a flood determination for insurance or lending; check the official FEMA Flood Map Service Center.
