Westchester County Property Records

Westchester County, immediately north of New York City, is the premier suburban county in the tri-state area. With approximately one million residents across 6 cities, 19 towns, and 23 villages, Westchester offers everything from dense urban living in Yonkers (the state's fourth-largest city) to the exclusivity of Bedford and Pound Ridge. The county's school districts — particularly Scarsdale, Bronxville, Edgemont, and Chappaqua — are among the highest-rated in the nation, driving persistent demand and premium pricing. Property professionals working in Westchester navigate a complex tapestry of municipalities, each with distinct zoning, assessment practices, and market dynamics.

Westchester County's real estate market is stratified by geography and school district more than perhaps any other suburban market in America. The "golden triangle" of Scarsdale, Bronxville, and Larchmont/Mamaroneck consistently ranks among the most expensive residential areas in the country, with median home prices often exceeding $1.5 million.

The Sound Shore communities — Rye, Harrison, Mamaroneck, and New Rochelle — offer waterfront living with Metro-North access to Grand Central. White Plains, the county seat, functions as a regional commercial center with a growing residential market including new luxury condos and transit-oriented development.

Northern Westchester — Bedford, Chappaqua, Katonah, and the river towns of Croton and Ossining — offers larger lots, more rural character, and somewhat more moderate (though still elevated) pricing. Yonkers and Mount Vernon in southern Westchester provide the county's most affordable housing, with ongoing revitalization efforts and transit access driving new investment.

RegWatch aggregates Westchester County property data from multiple authoritative sources:

• ORPTS Sales Records: Comprehensive sales data from the NYS Office of Real Property Tax Services — buyer/seller names, sale prices, deed references, and property classifications for every recorded transaction.
• NYS Statewide Parcels: Annual parcel dataset with owner names, assessed values, deed references, and property classifications for all Westchester parcels.
• Westchester County Clerk (WRO): The Westchester Recording Office maintains the official land records portal for deeds, mortgages, liens, and other recorded instruments. Online access available through the WRO system.
• NY Tax Warrants: State tax warrant data from the Department of Taxation and Finance identifies properties with outstanding state obligations.

Westchester County properties are identified by municipality, section, block, and lot. Because the county contains 48 separate municipalities — each with its own assessment roll — the municipality is an essential component of any property search.

The Westchester County Clerk's Recording Office (WRO) at wro.westchesterclerk.com provides online access to recorded documents. The WRO system allows searching by name, address, or instrument type, with document images available for download.

Assessment practices vary by municipality, though all follow the New York State Real Property Tax Law framework. Some Westchester municipalities assess at full market value while others use fractional assessment with equalization rates. The NYS equalization rate is essential for comparing assessments across municipal boundaries and for calculating the true tax burden on a property.

Westchester County's 48 municipalities include:

• Scarsdale: Consistently ranked among America's wealthiest communities. Top-rated schools, colonial and Tudor architecture, village character with high property values.
• Bronxville: A compact, walkable village with some of the highest per-square-foot values in suburban New York. Metro-North express service to Grand Central.
• White Plains: The county seat and commercial hub. Growing residential market with new luxury developments near the Metro-North station and Westchester Mall corridor.
• Yonkers: The state's fourth-largest city, with waterfront revitalization along the Hudson and a diverse mix of housing stock from affordable apartments to luxury condos.
• Rye: A Sound Shore community with historic charm, a waterfront amusement park (Playland), and premium real estate along the Long Island Sound.
• New Rochelle: Undergoing significant downtown redevelopment with transit-oriented projects near the Metro-North station. Mix of urban and suburban character.
• Chappaqua / Bedford: Northern Westchester communities known for large lots, equestrian properties, and a rural-suburban lifestyle within commuting distance of the city.
