Every Westchester property is in exactly one city or one town. If it is in a town, it may also be in a village. The county has six cities and 19 towns, and 20 villages sit inside those towns. Three more places, Scarsdale, Harrison and Mount Kisco, are each a town and a village at once.
Which one your property is in decides:
- which building department holds the certificate of occupancy (CO) file
- which offices send the tax bills
- which local rules apply when you sell
- where the title company orders its municipal searches
The mailing address won’t tell you, and getting it wrong sends searches to the wrong office. This guide covers Westchester County only. New York City has no towns or villages. For what each municipal search shows, see Westchester municipal searches explained.
How many municipalities Westchester has
The county says Westchester “is made up of six cities, 19 towns, and 20 villages” (About Westchester). Some sources say 23 villages. Both are right. The difference is Scarsdale, Harrison and Mount Kisco, which are each a town and a village with the same borders. Count them as towns and you get 19 towns and 20 villages. Count them as villages too and you get 23 villages.
How cities, towns and villages fit together
Cities stand alone. Under New York law, towns cover all land in the state except cities and Indian reservations (state guide to town government). A property in Yonkers, Mount Vernon, New Rochelle, White Plains, Rye or Peekskill is in that city and in no town.
Villages sit inside towns. Village residents “continue to be residents and taxpayers of that town” and “are liable for payment of taxes to the town in which their village is located” (state guide to village government). A house in the Village of Dobbs Ferry is also in the Town of Greenburgh.
Land outside any village belongs to the town only. This is called an unincorporated area, and the town governs it directly. Names like Edgemont, Valhalla, Armonk, Chappaqua or Katonah are hamlets or place names, not municipalities. The county map lists them separately as “Hamlets & Place Names” (Westchester County municipal map).
Three town/villages. Scarsdale, Harrison and Mount Kisco are each a town and a village with the same borders (NYS Department of State). Mount Kisco has been one since January 1, 1978 (Village/Town of Mount Kisco). There is no land outside the village, so one local government handles the property.
Two villages cross town lines. The Village of Briarcliff Manor is in both the Town of Ossining and the Town of Mount Pleasant, with over 91% of residents in Ossining (Village of Briarcliff Manor). The Village of Mamaroneck is in the Town of Mamaroneck and the Town of Rye; the Rye part is known as Rye Neck (Village of Mamaroneck). For these, it matters which side of the town line the lot is on.
Two towns are all villages. The Towns of Rye and Pelham have no land outside their villages and don’t control zoning or land use. They still charge and collect taxes (county Databook). Every Town of Pelham property is in the Village of Pelham or the Village of Pelham Manor. Every Town of Rye property is in Port Chester, Rye Brook or the Rye Neck part of Mamaroneck.
The City of Rye and the Town of Rye are different places. The city is its own municipality. The town contains Port Chester, Rye Brook and Rye Neck. A contract that says “Rye” needs to say which.
Which government handles what
| What | In a city | In a village | Town, outside villages |
|---|---|---|---|
| Building dept., COs | City | Village | Town |
| Local rules on sale | City | Village | Town |
| Town tax | None | Town | Town |
| Village tax | None | Village | None |
| County tax | City | Town receiver | Town receiver |
| School tax | Varies | Varies | Varies |
| Deed recording | County Clerk | County Clerk | County Clerk |
Building records and COs. The state building and fire code is enforced by each village, each town (outside its villages) and each city (NYS Department of State). So a house in the Village of Tarrytown is in Tarrytown’s building file, not Greenburgh’s. That also decides which local rules apply. Tarrytown requires an updated CO on sale, while unincorporated Greenburgh has different rules entirely. See which Westchester municipalities require an updated CO on sale. The county keeps a list of local building department contacts.
Property taxes. Westchester County doesn’t collect property taxes. Towns, cities and villages do (Westchester County Tax Commission). In a town, the receiver of taxes collects town and county taxes. Who collects village and school taxes varies:
- Briarcliff Manor collects its own village tax. Town and county taxes go to the Town of Ossining or the Town of Mount Pleasant, depending on where the lot is (Briarcliff Manor tax payment information).
- The Town of Pelham collects taxes for both villages, the schools, the town and the county (Town of Pelham).
- The Town of Rye receiver collects town, county, school and village taxes for Port Chester and Rye Brook, and serves the Rye Neck section of Mamaroneck (Town of Rye Tax Office).
- Harrison’s receiver collects town and village taxes and also acts as collection agent for school and county taxes (Town/Village of Harrison).
The county publishes a table of tax due dates by city, town and village, which shows where each one bills separately. School district lines don’t follow municipal lines either. Two districts, Briarcliff Manor and Ossining, serve the Village of Briarcliff Manor.
Recording and transfer tax. Deeds and mortgages for every Westchester municipality are recorded with the County Clerk; see recording a deed or mortgage in Westchester. Only three cities add their own transfer tax; see Yonkers, Mount Vernon and Peekskill transfer taxes.
Where the municipal searches go
Building, CO, fire, street and highway searches go to the government that holds the records. That is the city, the village if the property is in one, or the town if it is outside any village. The tax search has to cover every office that sends a bill. In a village that usually means the town receiver and the village.
In Scarsdale, Harrison and Mount Kisco there is one government. For a Briarcliff Manor or Village of Mamaroneck property, the tax search must go to the right town.
Why the mailing address misleads
Postal names follow post office areas, not municipal borders. The Village of Ardsley notes that Ardsley Road “is in unincorporated Greenburgh in an area known as Edgemont and with a Scarsdale postal address” (Village of Ardsley).
So a listing that reads “Scarsdale, NY 10583” may be in the Village of Scarsdale or in unincorporated Greenburgh. Those have different building departments, different taxes and different school districts. The Town of Greenburgh’s own buildings have Scarsdale, Hartsdale, Elmsford and White Plains mailing addresses (Welcome to Greenburgh packet).
How to confirm the municipality
- Read the tax bill. It names the town or city and any village. Its tax map number (section, block and lot) identifies the parcel.
- Check the county parcel viewer. The Westchester County GIS Municipal Tax Parcel Viewer searches by municipality, address, print key (parcel ID) or owner name. The county says its borders are approximate and only the local assessor holds the official tax maps, so it is a cross-check.
- Read the deed. The property description in the current owner’s deed names the city or town, and often the village. Recorded deeds are indexed in Westchester Records Online.
- Call the assessor if the lot is near a town or village line.
These checks come before ordering searches and before relying on a local requirement, such as a CO-on-sale rule or a sewer certificate.

Bedford, Lewisboro, New Castle, North Castle, North Salem, Pound Ridge, Somers and Yorktown contain no villages, so every property in them is governed by the town. Note the shared names: the City of Rye and the Town of Rye, the Town and Village of Mamaroneck, the Town and Village of Ossining, and the Town and Village of Pelham are separate municipalities with separate records.
Details for attorneys and title professionals
- The official count. The county Planning Department’s Databook counts “45 local governmental units, of which there are 6 cities, 16 towns, 20 villages and 3 town/villages” (Databook, Government). The state calls Scarsdale, Harrison and Mount Kisco “coterminous” town-villages (sharing the same borders) (NYS Department of State). Mount Kisco describes itself as a “coterminous and independent Village/Town.”
- Who enforces the building code. For enforcing the state Uniform Fire Prevention and Building Code, “local government” means “a village, town (outside the area of any incorporated village) or city” (NYS Department of State memo; state law). An incorporated village is one formally set up as its own local government.
- Towns of Rye and Pelham. The Databook says they “do not encompass any land that is not part of an incorporated village” and do not exercise land use regulatory authority (zoning and similar rules).
