Find the Right New York Parcel Record Before You Start Comparing Values
A New York parcel search is more local than many people expect. Outside New York City and a few special assessment systems, real-property records are generally organized through the city, town or county assessment structure, so there is no single statewide parcel-search box that replaces every local database.
The best statewide starting point is the New York State Office of Real Property Tax Services Municipal Data Portal. It helps you identify the correct county and municipality, check assessment-roll dates and equalization information, and find local contacts. From there, use the local assessor, county real-property office or GIS system for the actual parcel.
New York parcel search: choose your task
New York uses several different property systems, so start with what you actually need.
Quick answer: New York parcel searches usually begin locally
Find the municipality or county responsible for the assessment, then open its property-search or assessment-roll system.
Use New York’s Municipal Profiles tool to find local assessment contacts and roll information.
Use the county or municipal parcel viewer after identifying the correct assessing jurisdiction.
Use NYC Department of Finance tools and search by address or Borough-Block-Lot, known as a BBL.
Use the appropriate recording office. In NYC, ACRIS covers Manhattan, Queens, the Bronx and Brooklyn, while Staten Island recording involves the Richmond County Clerk.
Outside NYC and Nassau County, the usual formal grievance route uses Form RP-524 and the local Board of Assessment Review.
you will commonly see terms such as assessment roll, assessor, tax map number, parcel ID, SWIS code, equalization rate, Grievance Day and Board of Assessment Review. New York City instead relies heavily on the BBL identifier.
How to search New York property records
If the property is outside New York City, begin by identifying both the county and the city or town. Assessment administration in New York is often municipal, so searching only the county name can send you to the wrong office.
Know the town, city or village in which the property is assessed, not just its mailing address.
Choose the county and then the municipality, or use the portal’s search tool.
Municipal Profiles provides local contact information, equalization rates, assessment-roll dates and related statistics.
Search options can include owner name, street address, tax-map number, parcel ID or other locally used identifiers.
Match the address, tax-map identifier, legal-description clues, lot size and property characteristics.
Assessment, GIS, tax billing and recorded deeds may live on different local websites.
a postal city is not always the same as the assessing municipality. If a property has a mailing address associated with a nearby city but is physically in a town, use the town responsible for the assessment roll.
Who handles New York property records?
What you need |
Likely office or system |
What it does |
|---|---|---|
Parcel assessment |
Local Assessor |
Maintains the assessment roll and property valuation information. |
County parcel GIS |
County Real Property Tax Services / GIS |
Often provides parcel mapping, tax-map information and regional property data. |
Assessment calendar and equalization data |
NYS Office of Real Property Tax Services |
Provides statewide assessment guidance, municipal profiles, rates and standards. |
Local property-tax bill |
Local tax-collecting jurisdiction |
Bills and collects county, town, city, school or village taxes according to local arrangements. |
Recorded deed or mortgage |
County Clerk / City Register |
Maintains recorded real-estate documents. |
Assessment grievance |
Assessor / Board of Assessment Review |
Reviews formal complaints about current assessments outside special systems. |
The assessment roll is one of the most useful New York property records
Every assessing unit publishes a tentative and final assessment roll each year. The roll lists assessment information for properties in that jurisdiction and is often the easiest official source when a county GIS viewer does not show every valuation field.
Usually published May 1 in most towns and cities.
Check the property’s assessment and exemptions before Grievance Day.
A timely grievance can be heard by the Board of Assessment Review.
Usually published around July 1 in many communities.
How to read a New York assessment record
Field |
What it means |
What to check |
|---|---|---|
SWIS code |
A six-digit State Wide Information System identifier for the municipality. |
Useful for confirming the correct assessing jurisdiction. |
Parcel / tax-map ID |
The locally used identifier for the property. |
Use the exact format shown in the local system. |
Property class |
A numeric classification describing the property’s general use. |
Residential, vacant, commercial, industrial or another classification. |
School district |
The school district associated with the parcel. |
Important for school-tax and STAR questions. |
Parcel size |
Lot dimensions or acreage information recorded for assessment purposes. |
Compare with survey or deed information if acreage looks wrong. |
Land assessment |
The assessed value assigned to the land component. |
New York generally reviews the total assessment rather than grieving only the land component. |
Total assessment |
The assessed value of the parcel including land and improvements. |
This is the key assessment amount for grievance purposes. |
Full market value |
An estimate of what the property would sell for under normal market conditions. |
Do not assume assessed value must equal market value in every municipality. |
Exemptions |
Benefits reducing taxable assessed value for qualifying purposes. |
Review STAR and any other exemption listed on the roll. |
Use New York GIS parcel maps for location and context
Many counties maintain public tax-parcel GIS systems. These are useful for checking parcel shapes, nearby lots, roads, aerial imagery, tax-map identifiers and other geographic information.
Copy the tax-map or parcel identifier from the assessment record when possible.
Search by parcel number, address or owner when those search modes are offered.
This is especially useful for vacant land and rural property.
Some systems include aerial imagery, zoning, school districts, flood information or tax districts.
GIS data is normally informational and should not replace a professional survey for legal boundary questions.
GIS parcel lines can be generalized or shifted relative to imagery. Use recorded documents and a licensed surveyor when an exact property line matters.
New York assessed value does not always equal market value
One of the biggest mistakes in a New York parcel search is assuming that a property’s assessment should always match its current sale price dollar for dollar.
Outside New York City’s and Nassau County’s special assessment systems, a municipality generally assesses properties at a uniform percentage of market value. That percentage can be below 100%.
if a municipality assesses property at 50% of market value and a home has a $200,000 assessment, its implied full market value would be about $400,000.
Why equalization rates matter in a New York property search
The state equalization rate measures the relationship between the total assessed value of taxable property in a municipality and its estimated total market value.
Property in the municipality is generally being assessed at full market value.
Assessments are generally below full market value, even if they are still applied uniformly.
Equalization helps distribute taxes fairly across jurisdictions and is also used in several property-tax calculations.
New York City parcel searches work differently: use the BBL
New York City is a special assessing unit and uses the Borough-Block-Lot identifier, usually shortened to BBL. If the property is in Manhattan, Brooklyn, Queens, the Bronx or Staten Island, NYC Department of Finance tools are more useful than a typical county assessor search.
Search by BBL, address, block, condominium number, co-op development number and other identifiers.
Look up tax class, market value, property-tax bills, notices of property value and exemption information.
Search recorded deeds, mortgages and related documents for Manhattan, Queens, the Bronx and Brooklyn from 1966 forward.
Review official NYC tax-lot mapping and related parcel information.
How to find an NYC property by BBL
Choose the address search if you do not already know the BBL.
Confirm the result matches the intended building or lot.
The BBL is useful across multiple Department of Finance systems.
Search by parcel identifier, party name or other available criteria.
The recorded deed system is not the tax-payment system.
NYC’s City Register maintains recorded property documents for the other four boroughs. Staten Island real-estate recording functions are handled through the Richmond County Clerk, although NYC property-tax and BBL systems still apply.
Nassau County is also a special assessment system
Nassau County should not be treated like an ordinary town-level New York assessment search. New York State classifies Nassau County, along with New York City, as a special assessing unit.
If you are researching a Nassau parcel, use Nassau County’s assessment and property-search resources for the parcel itself. If the assessment is disputed, the formal administrative review route goes through the Nassau County Assessment Review Commission, not the standard town Form RP-524 procedure used in many other parts of the state.
always check whether your property is in NYC or Nassau County before following generic New York grievance instructions.
Parcel records are not the same thing as deed records
An assessment database can tell you who is associated with a parcel for tax purposes, but it should not be treated as a complete title search.

Typical New York property-assessment calendar
Dates can vary by municipality, and NYC and Nassau County use different procedures. For many towns and cities, however, the annual cycle follows this general pattern.
Stage |
Typical timing |
What to do |
|---|---|---|
Tentative assessment roll |
May 1 in most towns and cities |
Review assessment, exemptions and property details. |
Grievance Day |
Fourth Tuesday in May in most communities |
File the grievance by the local deadline if disputing the current assessment. |
Final assessment roll |
Around July 1 in most communities |
Confirm the final assessment and any Board of Assessment Review change. |

Assessment-calendar dates vary in some cities, towns and villages, and NYC and Nassau County have separate procedures.
How to challenge a New York property assessment
Outside New York City and Nassau County, a taxpayer can generally contest the current tentative assessment by filing Form RP-524, Complaint on Real Property Assessment.
Make sure you are contesting the current year’s assessment, because prior-year assessments cannot be grieved through the current grievance process.
Ask how the value was determined and review the property’s inventory and assessment information.
Explain why the assessment is incorrect and include relevant supporting evidence.
In many communities that is the fourth Tuesday in May, but verify the date through the assessor or Municipal Profile.
The Board can request additional information or an appearance.
Eligible residential owners may use Small Claims Assessment Review, while other cases may require a tax-certiorari proceeding.
New York State says there is no fee to file a standard assessment grievance with the Board of Assessment Review.
Small Claims Assessment Review carries a $30 filing fee for eligible property owners.
SCAR and tax-certiorari proceedings generally must be started within 30 days after the final assessment roll is filed or notice of that filing, whichever is later.
Check STAR when researching a New York home’s property taxes
STAR is a New York school property-tax benefit for qualifying owner-occupied primary residences. It does not change the property’s market value, so it should be considered separately from the parcel’s assessment.
STAR type |
2026 eligibility highlights |
Important detail |
|---|---|---|
Basic STAR credit |
Primary residence; income of $500,000 or less under current credit rules |
No age requirement. |
Existing Basic STAR exemption |
Existing qualifying exemption recipients; $250,000 income limit |
The exemption program is closed to new applicants. |
Enhanced STAR |
At least one resident owner generally must be 65 by December 31 of the benefit year |
2026 income limit is $110,750 under current state guidance. |
new applicants generally register for the STAR credit rather than applying for a new STAR exemption.
Common New York parcel-search problems
Try the city or town assessor. In much of New York, the municipality is the assessing unit.
Confirm the actual town or city in which the parcel is physically assessed.
Assessment records may not update at exactly the same time as recorded documents. Check the recording office.
Check the municipal level of assessment or equalization rate before concluding the parcel is undervalued.
Search by tax-map number, parcel ID or use the county GIS viewer.
Use the NYC address-to-BBL lookup first, then reuse that identifier across DOF and ACRIS tools.
GIS is not a boundary survey. Check the deed and a professional survey when the property line matters.
Contact the assessor immediately to understand whether any current remedy remains. Do not assume next year’s grievance can change a prior-year assessment.

New York parcel search FAQs
1. Is there one statewide New York parcel-search website?
No. New York provides statewide municipal and assessment information through ORPTS, but parcel-level records are generally maintained by local assessing jurisdictions, counties or special systems such as New York City.
2. Where should I start a New York parcel search outside NYC?
Start with the ORPTS Municipal Data Portal. Identify the county and municipality, check the local assessor information, and then use that municipality’s or county’s parcel, assessment-roll or GIS system.
3. What is a SWIS code?
A SWIS code is a six-digit New York State identifier for a municipality. The first two digits identify the county, the next two identify the city or town, and the final pair can identify a village where applicable.
4. Why is my New York assessed value lower than the property’s market value?
Many New York municipalities assess property at a uniform percentage below 100% of market value. Check the local level of assessment or state equalization rate before comparing assessed value directly with a sale price.
5. What is a BBL in New York City?
BBL means Borough-Block-Lot. It is New York City’s key parcel identifier and is used across Department of Finance property, tax-map, tax-bill and ACRIS systems.
6. When is the tentative assessment roll published in New York?
In most towns and cities, the tentative assessment roll is published on May 1. Local schedules can vary, so confirm the date for the actual assessing municipality.
7. When is New York Grievance Day?
In most communities, Grievance Day is the fourth Tuesday in May. Some municipalities use a different schedule, and New York City and Nassau County follow separate assessment-review procedures.
8. How much does it cost to grieve a New York property assessment?
There is no fee to file the standard administrative grievance with the local Board of Assessment Review. Eligible Small Claims Assessment Review cases have a $30 filing fee.
9. Can I use a New York GIS parcel map as a legal survey?
No. GIS is useful for locating parcels and reviewing map context, but it should not replace recorded documents or a professional boundary survey when exact legal boundaries matter.
10. Can a new New York homeowner apply for the STAR exemption?
The STAR exemption program is closed to new applicants. New homeowners and first-time applicants generally register with New York State for the STAR credit if they meet the eligibility rules.
