Connecticut has no active county governments — Fairfield County is a historical/geographic designation. Property records are maintained per-municipality and aggregated into the statewide CT CAMA & Parcel Layer 2024 (the SAME FeatureServer used for Hartford and New Haven Counties). To scope to Fairfield County you MUST filter by Town_Name. Fairfield County towns: Bridgeport, Stamford, Norwalk, Danbury, Fairfield, Westport, Greenwich, Stratford, Trumbull, Shelton, Monroe, Newtown, Ridgefield, Wilton, Weston, New Canaan, Darien, Bethel, Brookfield, Easton, Redding, Sherman, New Fairfield. Verified 2026-06-20: Town_Name='Stamford' returns 25,719 parcels; UPPER(Owner) LIKE '%SMITH%' returns real residential parcels (e.g. '92 SHADY LANE'). NOTE: Parcel_ID may be blank for some towns; Owner + Location_1 remain populated. For authoritative records use the relevant town Assessor's office.

Fairfield County's Connecticut_CAMA_and_Parcel_Layer layer exposes a parcel identifier (Parcel ID (may be blank for some towns)), owner names (Town Name (REQUIRED filter — set to a Fairfield County town, e.g. Bridgeport, Stamford, Norwalk, Danbury, Fairfield, Westport), Owner Name, Co-Owner Name), and address fields (Property Location / Address, Mailing Address). Use it for owner-name lookups and address-based parcel searches. 6 of 17 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS FeatureServer layer, so edits and applyEdits operations are technically exposed (read access only is published here); last verified 2026-06-20.
/query?where=…&outFields=*&f=jsonto the URL. The sample query above is a working example you can paste into a browser tab to see the raw JSON response.Counties publish parcel data through their own ArcGIS Server installations, each with its own schema. One county uses APN, another uses PIN, a third uses PARCEL_ID. Some expose owner names; others keep them on a separate assessor's portal. The searchable fields list above reflects what Fairfield County actually publishes — not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
Many county servers allow public reads but block browser cross-origin requests. The UrbanKit parcel lookup tool fetches directly from your browser; if it works there, the layer is technically public. For your own integration, you may need a same-origin proxy or server-side fetch.
Possibly — counties move services without warning. We re-verify entries weekly and flag stale ones. If you're seeing a fresh 404, please let us know and we'll update the listing.
Most are. Public ArcGIS layers don't typically rate-limit individual reads, but heavy programmatic use can trigger throttling at the host level. Be respectful — query what you need.
