Property Neighbors

Returns nearby comparable parcels for a subject property. County-specific logic determines the search strategy — spatial radius for ArcGIS counties, address-adjacent lookup for others. Ideal for appraisal protest and CMA workflows.

Parameters

addressstringrequired

Subject property address. Used as the center point for the neighbor search.

countystringoptional

County hint. If omitted, ParcelKit geocodes the address to determine the county.

latstringoptional

Latitude in decimal degrees. Required for counties using spatial radius queries.

lonstringoptional

Longitude in decimal degrees. Pair with lat.

The source field in the response indicates the lookup strategy used — live_gis for spatial ArcGIS queries, address_adjacent for address-based fallback. Spatial results are more geographically accurate; adjacent results follow street numbering.
