Find New York Property Records Using the Correct Local Parcel Search
Looking for a New York parcel number, property owner, assessment value or GIS map? The first thing to know is that New York does not have one public parcel-search system covering every property in the state. Records are maintained through local assessing offices, county systems and special property databases for New York City and Nassau County.
Most searches begin with the city or town where the property is assessed. New York City’s five boroughs instead use the Borough-Block-Lot (BBL) system, while Nassau County has its own countywide assessment and review procedures.
This guide helps you choose the right official search, read property values, find tax maps, research ownership and understand what to do when an assessment looks wrong.
Quick answer: which New York property system should you use?
How to search a New York parcel by address, owner or tax-map number
For property outside NYC, the New York State Office of Real Property Tax Services (ORPTS) Municipal Data Portal is a useful first stop. It identifies local governments and assessment contacts, but it is not a replacement for every county or municipal property database.
- Identify the property’s assessing municipality.Confirm the county and the town, city or other assessing unit. If the postal address is unclear, check an old tax bill or legal description.
- Open the ORPTS Municipal Data Portal.Choose Municipal Profiles, then select the county from the map or County list. Select the municipality afterward.
- Check the municipal profile.Review the local assessor contact, assessment-roll dates, equalization rate and available municipal information.
- Find the local property database or roll.Use the assessor or county website to locate the parcel-search portal, assessment-roll files or GIS viewer.
- Search with a reliable identifier.Depending on the portal, use the tax-map number, section-block-lot, address, owner name or other supported field.
- Verify the matching parcel.Confirm the situs address, land area, school district, classification and assessment before relying on the result.
- Follow the correct service for your next task.For the current balance, locate the relevant tax-collecting authority. For deed history, use the recording office.
New York parcel-search options by region
These examples show why a statewide search can require different portals. A town’s assessor and a county’s GIS department may both publish useful information about the same property.

New York parcel identifiers: tax-map numbers, SWIS and NYC BBL
When copying an identifier from an old document, preserve leading zeros and separators until you know the current portal’s accepted format. Do not assume an SBL from one county works in the same form in another county.
How to use New York GIS parcel maps
GIS viewers can show parcel outlines, roads, aerial photos, acreage and nearby features. These maps are particularly useful for vacant lots and rural properties without a conventional street address.
- Get the parcel number.Use the local assessment roll or property search where possible.
- Open the county or municipality’s GIS viewer.Find it through the government website rather than an unrelated map listing.
- Search for the parcel.Try the tax-map number first, then use address or other options offered by the viewer.
- Confirm the location.Compare surrounding streets, adjoining parcels and visible features.
- Review available layers.Some maps include zoning, flood zones, aerial imagery, municipal limits or school districts.
- Use the result for research, not boundary certification.Parcel outlines are not guaranteed legal survey lines.
Why New York assessed value and market value can be different
In many New York municipalities, property is assessed at a uniform percentage of market value rather than at 100%. That makes an assessment number misleading unless you know the municipality’s level of assessment.
The equalization rate helps compare jurisdictions and apportion taxes. It is not a guaranteed appraisal of one particular property. For an individual valuation dispute, check the stated assessment level and comparable property evidence.
How property assessment connects to New York property taxes
Assessment and the final tax bill are related, but they are different records. Tax rates and bills are determined through the relevant taxing jurisdictions, which may include county, town, city, village and school district taxes.
New York City parcel search: BBL, property values and ACRIS
Property in Manhattan, Brooklyn, Queens, the Bronx or Staten Island is best researched through New York City Department of Finance services. The BBL is the most useful identifier for moving between NYC property tools.
How to find an NYC tax lot
- Open the NYC Property Information Portal.Begin with the address if you do not have the BBL.
- Confirm the borough and lot.Save the displayed borough, block and lot details.
- Read the property information.Review the tax class, market value, assessed value history and land/building characteristics when provided.
- Use NYC Finance for bills and exemptions.The current balance and notices belong to the property-tax system.
- Use recorded-document tools for deeds.ACRIS serves Manhattan, Brooklyn, Queens and the Bronx; Staten Island recording is handled by the Richmond County Clerk.
Nassau County uses its own assessment and appeal system
Nassau County is a special assessing unit. Its Department of Assessment handles property valuation, while the Assessment Review Commission (ARC) reviews assessment challenges. Do not follow an ordinary town-based grievance process for a Nassau property.
The County uses an online review system called Assessment Review on the Web (AROW). Nassau County currently lists its next assessment-appeal filing period as January 4 through March 1, 2027, for the upcoming assessment cycle.
- Find the County’s assessment record.Confirm the parcel, property class and valuation under dispute.
- Open the official ARC appeal page.Review the current filing period and instructions.
- Use AROW during the filing window.Follow the County’s instructions for the appropriate property and appeal type.
- Keep filing confirmation.AROW also provides access to pending and past appeal status.
How to challenge a New York property assessment
For most New York municipalities outside NYC and Nassau County, the ordinary administrative challenge is made through the local Board of Assessment Review using Form RP-524.

- Review the Board’s decision.Eligible owners may have further review options, including Small Claims Assessment Review or a court proceeding, subject to deadlines.

New York parcel-search troubleshooting
New York parcel search FAQs
1. Can I search every New York parcel on one statewide website?
No. The state Municipal Data Portal helps locate assessment contacts and municipal information, but parcel records are generally maintained by local or county systems, with separate arrangements for NYC and Nassau County.
2. Where do I start a New York parcel search outside NYC?
Start with the ORPTS Municipal Data Portal, find the county and assessing municipality, then use that local assessor’s assessment roll or property-search system.
3. What is a SWIS code on a New York property record?
It is a six-digit State Wide Information System code identifying a municipality. It helps locate the correct assessing jurisdiction and roll.
4. Can I search New York property records using an owner name?
Many county and municipal systems offer owner searches, but not all use the same fields. Try the tax-map number or property address if owner search is unavailable.
5. Why is a New York assessed value lower than market value?
Some municipalities assess at less than full market value. Check the municipality’s stated level of assessment and equalization information before comparing figures.
6. What is a BBL in New York City?
BBL stands for Borough-Block-Lot. It identifies an NYC tax lot and is used in property, assessment and recorded-document research.
7. When is Grievance Day in New York?
Usually the fourth Tuesday in May for many towns and cities. Dates can differ, and NYC and Nassau County use separate procedures.
8. Is Nassau County assessment review different?
Yes. Nassau County uses the Assessment Review Commission and the AROW online appeal system. Its announced next filing period is January 4–March 1, 2027.
9. Can a new homeowner apply for the STAR exemption?
The STAR exemption is closed to new applicants. Eligible new homeowners generally register for the STAR credit through New York State.
10. Can an online New York GIS map prove a property boundary?
No. GIS parcel maps are useful for research, but a professional survey and recorded documents are the appropriate sources for exact legal boundary questions.

Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties.
