How to Find Property Lines in New York: County Records, Filed Maps, and Surveys

Updated September 2, 2026 · 3 min read · Property Owner Questions

Quick answer

Use New York's parcel data or the local assessor to identify the tax parcel, then obtain the deed and filed subdivision or survey maps from the county clerk. New York City uses a different document system. When a line must be marked for construction, title, or a dispute, hire a New York-licensed land surveyor.

The record path changes at New York City's border

For most of New York, deeds and filed maps are county records. Begin with the local assessment parcel, save the tax-map identifier, and search the county clerk's land records. In New York City, ACRIS is the official system for recorded property documents in Manhattan, Bronx, Brooklyn, and Queens; Richmond County records use the city's separate Staten Island recording path.

The New York State parcel program helps identify parcels and the local source. It does not certify where a deed line falls on the ground. Data completeness, attributes, and update timing depend on local contributors.

Retrieve the document that created the lot

If the deed describes a numbered lot, find the filed subdivision map and any amendments. If it uses metes and bounds, follow prior deeds and adjoining references. In older villages, cities, and rural tracts, a tax map can conceal a longer record chain. On a co-op or condominium property, confirm whether the question concerns a tax parcel, a condominium unit, common elements, or an exclusive-use area before ordering field work.

When record research should become a survey

  • A fence, wall, pool, driveway, or addition will approach the line.
  • A title or lender request names a specific survey product.
  • A neighbor disputes a monument, fence, drive, or access route.
  • The deed, filed map, occupation, and assessed acreage do not agree.
  • A rural, shoreline, or downstate parcel has a complex description or access issue.

New York's Education Law Article 145 regulates professional land surveying. A licensed surveyor can retrace the boundary and take responsibility for the signed result; a parcel overlay cannot.

Make a New York survey request easy to scope

Provide the borough or county, municipality, street address, tax-map identifier, deed, filed map, prior survey, title request, and photos. For a fence, state which side needs stakes. For a closing, ask the lender or title attorney exactly which survey and certification they require.

Verify and compare

Check the responsible individual in the NYSED verification search. Ask what field marking and signed deliverable are included and whether the firm regularly researches that county's records.

Frequently Asked Questions

Where are New York deeds recorded?

Outside New York City, begin with the county clerk or county land-record system where the property lies. In New York City, use ACRIS for recorded real-property documents in Manhattan, Bronx, Brooklyn, and Queens, with separate procedures for Staten Island.

Is the New York statewide parcel layer a survey?

No. The state parcel program aggregates local tax-parcel data for mapping and discovery. Use it to identify the municipality and parcel, then retrieve the deed and filed maps and hire a surveyor when field location matters.

How do I verify a New York land surveyor?

Use the New York State Education Department's online verification search and confirm the individual responsible for the work.
