Tax parcel lookup for the western Catskills and the Delaware River headwaters
Delaware County covers a large, rural stretch of the western Catskills, where the east and west branches of the Delaware River begin. Much of New York City's upstate reservoir system — including the Cannonsville and Pepacton reservoirs — sits within the county, alongside Delhi, the county seat, and small river-valley towns throughout.
NY Property Peek's dataset includes over 43,000 individual tax parcels across Delaware County, each with details like year built, square footage, bedroom and bathroom counts, and school district where available — pulled from New York State's statewide tax parcel records.
