155M+ US parcels. Boundary-level precision.
Regrid provides the parcel data backbone for Relio's map view. Boundary overlays, address search, ownership records, tax assessments, zoning data, and building footprints — all standardized across every county in the US.
What Regrid powers in Relio
Five capabilities, all driven by a single API key.
Parcel Boundary Tiles
Vector tile overlays render parcel boundaries directly on Relio's Mapbox map. Zoom levels 4 through 20 — from state-wide coverage down to individual lots. Boundaries load on demand through a server-side proxy that keeps your API token secure.
Address Typeahead Search
Search for any US address and get instant parcel matches. Each result returns the parcel centroid, address, unique identifier, and geometry — ready to place on the map or pull into a record.
120+ Property Data Fields
Every parcel comes with standardized data: ownership, mailing address, assessed values, sale price, year built, square footage, lot size, zoning, legal description, and more. One click on the map fills in the details.
Building Footprints & Zoning
Optional data layers return matched building footprints (with square footage, height, and stories) and zoning overlays (with FAR, lot coverage, density, and maximum building height).
Usage Dashboard
Track API consumption by billing cycle — requests, tiles served, features returned, typeahead calls, and building/zoning lookups. Full history by token for multi-key setups.
Click any parcel. Get the full picture.
Stop toggling between county GIS portals and your CRM. When you click a parcel on Relio's map, the data is already there — pulled from Regrid's standardized dataset covering 155M+ parcels across the US. Owner name, mailing address, assessed value, last sale price, year built, lot size, zoning classification. Every field mapped to Relio's property record schema automatically.
- Instant data on click — no manual lookups
- 120+ standardized fields per parcel
- Ownership chain and mailing address
- Tax assessments and sale history
- Parcel geometry for boundary display

Vector tiles that just work.
Parcel boundary overlays render as vector tiles on Relio's Mapbox map, supporting zoom levels 4 through 20. At city scale you see neighborhood-level boundaries. Zoom in and individual lot lines resolve with full precision. Tiles are served through a server-side proxy — your Regrid API token never reaches the browser. No CORS issues, no client-side key exposure.
- Vector MVT tiles for crisp rendering at any zoom
- Server-side proxy keeps tokens secure
- Zoom levels 4 (state) through 20 (lot level)
- On-demand loading — only tiles in viewport
- Compatible with all 4 Relio map styles
Split view: left shows zoomed-out city view with parcel boundaries visible as a grid overlay, right shows zoomed-in street-level view with individual lot boundaries, building footprints visible.
Enhanced ownership and zoning data.
Go beyond basic parcel records. Regrid's optional data layers return matched building footprints — with building square footage, estimated height, number of stories, and source attribution. Zoning overlays include municipality name, zoning code and description, zoning type and subtype, maximum building height, floor area ratio (FAR), lot coverage percentage, and maximum density per acre.
- Matched building footprints with geometry
- Building sqft, height, stories, gross area
- Zoning code, type, subtype, and description
- Max building height, FAR, lot coverage
- Density limits (dwelling units per acre)
Property detail panel showing enhanced data sections: Building Footprint (12,400 sqft, 3 stories, 45ft height), Zoning (C-2 Commercial, FAR 3.0, 80% coverage, 60 du/acre).
