Almost every North Shore transaction eventually collides with the same question. A buyer looks at two houses eight minutes apart, one in Roslyn Estates and one in Roslyn Heights, and cannot work out why one carries a village tax line and the other does not, why one owner pulls permits from a village building department and the other from the Town of North Hempstead, or why two homes with the same Roslyn mailing address are assigned to two different school districts.

None of that is an accident, and none of it is a quirk of the local market. It is the ordinary structure of New York local government, layered onto a stretch of Nassau County that happens to contain an unusually dense cluster of incorporated villages. Once you can see the layers, the North Shore stops being confusing and starts being legible. This page is the map.

We are The Scout Residential Team at Compass, working out of 69 Roslyn Road in Roslyn. We sell more homes in Roslyn than any other team, which means we spend a great deal of time answering exactly these questions on exactly these blocks. What follows is factual civic structure: who governs what, what changes on a tax bill, and how to confirm any of it for a specific address. It is not advice about where anyone should live.

Which Layers of Government Actually Govern a North Shore Home?

Every home on the North Shore sits inside a stack of separate governments. They are genuinely separate: different budgets, different elected boards, different boundaries. The single most common mistake buyers and sellers make is assuming these layers nest neatly inside one another. They do not.

Layer one: Nassau County

Nassau County is the largest unit. The county seat is Mineola, and the 2020 census recorded 1,395,774 residents countywide. The county handles assessment of real property, the county police department in most of the county, county roads, and county courts. Nassau County is divided into two cities, Glen Cove and Long Beach, and three towns, Hempstead, North Hempstead, and Oyster Bay. Those three towns contain 64 incorporated villages and more than 60 unincorporated hamlets. The North Shore markets sit almost entirely in North Hempstead and Oyster Bay, with the City of Glen Cove as a separate case.

Layer two: the Town

The Town of North Hempstead recorded 237,639 residents in 2020 and contains 31 incorporated villages plus roughly 21 unincorporated hamlets and census-designated places. The Town of Oyster Bay recorded 301,332 residents and contains all or part of 20 incorporated villages plus all or part of 18 unincorporated hamlets and census-designated places. Towns run building departments and zoning for their unincorporated areas, highway maintenance, sanitation districts, parks, and the Receiver of Taxes office that bills most property taxes.

Layer three: the Village, if there is one

An incorporated village is a self-governing municipal corporation that sits inside a town. Some North Shore homes are in one and some are not. This is the layer that changes the most for a buyer or a seller, and it is covered in detail below.

Layer four: the special districts

Overlaying all of the above are independently governed districts with their own boundaries and their own budgets: school districts, fire districts, water districts, library districts, sanitation districts, and in one case a police district. These boundaries were drawn for their own reasons over more than a century, and they routinely cut across village and town lines. This is the layer responsible for nearly every surprise in a North Shore purchase.

What Is an Incorporated Village on the North Shore?

An incorporated village in New York is a municipal corporation with its own government. Its legislative body is a board of trustees, composed of a mayor and usually four trustees. On many small North Shore villages those trustees serve short terms and serve unpaid. The Village of Flower Hill, for example, is governed by a seven-member board of trustees made up of an elected mayor and six elected trustees, all serving two-year terms, all unpaid.

Under current New York Village Law, the territory proposed for incorporation must contain a population of at least 1,500 regular inhabitants, and in most cases must not exceed five square miles, unless its boundaries would be coterminous with a school, fire, improvement or other district, or with the entire town. Incorporation begins with a petition signed by 20 percent of residents or the owners of 50 percent of assessed real property, followed by a vote. Most North Shore villages predate the current thresholds, which is why several of them are far smaller than a new village could be today. Roslyn Estates covers 0.44 square miles and recorded 1,318 residents in the 2020 census.

Most of the villages that define the Roslyn market were created in a single burst in the early 1930s. Roslyn Estates incorporated on June 8, 1931. Flower Hill incorporated on May 25, 1931. East Hills incorporated on June 24, 1931. Roslyn Harbor incorporated on October 17, 1931. The Village of Roslyn itself incorporated on January 11, 1932. Others are much older: Sea Cliff dates to 1883, Sands Point to 1910, and Old Westbury to 1924.

The critical legal point, and the one that surprises people most: a village does not leave its town. Villages legally remain part of the town or towns in which they are located. Village residents pay both town and village taxes, and vote in both town and village elections. Roughly 85 percent of New York villages sit entirely within one town. About 15 percent cross a municipal boundary, and the North Shore has several of those.

What a village typically controls

The powers a village exercises are the ones a homeowner feels most directly:

What a village usually does not control

Equally important is what stays outside village hands. The village does not set your school district, and cannot change it. The village does not perform the property assessment; Nassau County does. Fire protection generally comes from a fire district, water from a water district, and library service from a library district, each with its own boundary. The Village of Roslyn Estates, for instance, is served by the Roslyn Fire District for fire, the Roslyn Water District for water, and the Nassau County Police Department’s Sixth Precinct for police. None of those three is a village function. Roslyn Harbor makes the point even more sharply: its library service is split along school district lines, with The Bryant Library serving the portion inside the Roslyn Union Free School District and the Gold Coast Library District serving the portion inside the North Shore Central School District. One village, one mayor, two library cards.

Services a village does not provide are provided by the town or towns containing the village. That division varies village by village, which is why “what does the village actually do here” is a real question and not a rhetorical one.

What Is an Unincorporated Hamlet?

A hamlet is a named community with no government and, strictly speaking, no legal boundaries. As the standard description puts it, a hamlet has no government of its own and depends upon the town or towns that contain it for municipal services and government. Nassau County has more than 60 of them.

For a homeowner, the practical consequences are clean:

• Zoning and building permits come from the Town of North Hempstead or the Town of Oyster Bay, not from a village hall.
• Road maintenance in the hamlet is a town highway function.
• Garbage collection runs through a town sanitation or solid waste district.
• There is no village line on the tax bill, because there is no village.
• There is no village mayor, no village board, and no village election.

On the North Shore the significant hamlets include Roslyn Heights, Albertson, Greenvale, Port Washington, Manhasset, Searingtown, Herricks, Manhasset Hills, Glen Head, Glenwood Landing, Locust Valley, East Norwich, Jericho, Syosset, Woodbury, and the hamlet of Oyster Bay. That last one is worth pausing on. The hamlet of Oyster Bay sits inside the Town of Oyster Bay, and the two are not the same entity. A property described as being “in Oyster Bay” may mean the hamlet, or it may mean anywhere across a town of more than 300,000 people that also contains Jericho, Syosset, Woodbury, Bethpage, Hicksville, Massapequa, and Plainview.

There is one notable exception to the pattern that hamlets receive county policing. The Port Washington Police District is not a village department but is authorized by a special district, and it is the only such district in the State of New York.

What Actually Changes for a Buyer or a Seller?

This is the part that has money attached to it. Village or hamlet status changes five practical things.

1. Taxes: how many bills arrive, and from whom

In Nassau County, the Town Receiver of Taxes is the collection point for most property taxes. The Town of North Hempstead’s office states plainly that it “bills and collects all Town, County, School, and Special District taxes within North Hempstead.” The Town of Oyster Bay describes its Receiver as acting “as a collection agency for the State (Supreme Court), County, Town, special district and school district taxes based upon budgets adopted by the respective municipal authorities.”

Read those lists carefully. Neither includes village taxes. A village levies and bills its own tax on its own schedule, which is why a village homeowner has an additional bill, an additional due date, and an additional budget vote to pay attention to. A hamlet homeowner does not.

Two important cautions. First, more tax bills does not automatically mean a higher total tax burden, because the village layer funds services the town would otherwise fund, and because the school tax is usually the largest single component regardless of village status. Second, Nassau County performs the assessment, so the assessed value driving every one of these bills is a county determination, not a village one.

2. Permits: whose building department you answer to

If you are renovating, adding, subdividing, putting in a pool, or building new, the jurisdiction that reviews your plans depends entirely on this distinction. Inside a village, the village code and village building department govern, and many villages add architectural review on top. In a hamlet, the town code and the town building department govern. The practical difference shows up in review timelines, in what is permitted as of right, and in what an open permit or a missing certificate of occupancy will cost a seller at closing. On the sell side, this is one of the most common late-stage deal problems we see, and it is entirely preventable by checking early.

3. Garbage, roads, and water

Sanitation is a good example of how little the mailing address tells you. In a hamlet, refuse collection typically runs through a town solid waste or sanitation district. In a village, it may be a village service, a village-contracted private carter, or still a town district, depending on the village. Roads work the same way: village-owned streets are maintained by the village, town streets by the town, and county roads by the county. Roslyn Road is a county road, carried as Nassau County Route 7A, which runs from Peninsula Boulevard in the Village of Hempstead north to West Shore Road and Old Northern Boulevard in Roslyn, becoming Main Street near its northern end. Water usually comes from an independent water district, such as the Roslyn Water District, and a water district boundary is drawn independently of village and school district lines.

4. Police

This is a question about which agency provides a municipal service, and nothing else. The Nassau County Police Department was formed in 1925 and covers most of the county. The Village of Roslyn Estates and the Village of Flower Hill are both served by its Sixth Precinct. Some jurisdictions declined to join the county police district at its formation, and others established departments later, so they maintain their own forces. On the North Shore that group includes Sands Point, Old Westbury, Old Brookville, and Brookville, whose own department was established in 2022 after the Old Brookville Police Department announced a change in its coverage. Port Washington, an unincorporated hamlet, is covered by the Port Washington Police District, which also serves the incorporated villages of Baxter Estates and Port Washington North and is the only special police district in New York State.

5. Voting and local governance

Village residents vote in village elections in addition to town, county, state, and federal elections, and separately in school district budget and board elections. That is a real difference in how much local say a homeowner has over zoning and code, and it is one of the things buyers moving out from the city most often do not anticipate.

What Does Village or Hamlet Status Change for a Seller?

Most writing on this subject is aimed at buyers. On the North Shore the seller carries more of the exposure, because each of these jurisdictional facts becomes a representation the seller makes, and each one is checkable by the other side before closing.

The permit file lives with whoever has jurisdiction

If the home sits inside an incorporated village, the certificates of occupancy, the permit history, and any open or expired permits are held by the village building department, not by the Town of North Hempstead or the Town of Oyster Bay. If it sits in a hamlet such as Roslyn Heights, Albertson, or Greenvale, the town holds the file. Sellers often learn which office holds their records only after a buyer’s attorney requests them, which is the most expensive moment to find out. A finished basement, a deck, a pool enclosure, a generator, or a rear addition completed under a prior owner is the usual culprit. Pulling the file at listing time, from the correct jurisdiction, converts a closing-table problem into a pre-market repair.

A village home carries a tax bill the town never sends

The Town Receiver of Taxes bills county, town, school, and special district taxes. It does not bill village taxes. A seller in Roslyn, Roslyn Estates, Roslyn Harbor, East Hills, Flower Hill, or any other incorporated village who quotes an annual tax figure from the town bill alone is understating the annual carrying cost, and a buyer will find the village bill during due diligence. Quote both, or quote the combined total and state what it comprises. A hamlet seller has no village line and can present the town bill as the complete picture.

The school district line on a listing is a factual claim, not a marketing line

Because district boundaries cut through East Hills, Flower Hill, Roslyn Harbor, Old Westbury, Roslyn Heights, Albertson, and Greenvale, a district stated from memory, from a portal, or from a neighboring listing is a real liability. Assignment is parcel-specific and belongs in writing from the district registrar. Stating it correctly also protects the price, because a listing marketed against the wrong comparable set draws the wrong buyer pool and corrects downward later.

Village review boards shape what a buyer can do next

Many villages operate architectural or design review in addition to standard zoning, and village codes govern setbacks, lot coverage, height, accessory structures, pools, fences, and generators. When a property’s value depends on expansion potential, what the village will approve and how long approval takes is part of the value story. Both are answerable in advance from the village code and the building department, and answering them in advance is a pricing advantage rather than a disclosure chore.

This is the practical reason we treat jurisdiction as a listing preparation step and not a closing formality. Most of our work is on the sell side, and on the North Shore the sell-side work that actually moves price happens before the first showing.

Why Does a Mailing Address Not Tell You Your School District?

Because they were never drawn to match. A ZIP code is a United States Postal Service mail delivery route. A village boundary is a municipal corporation line set at incorporation and amended since. A school district boundary is the line of an independent unit of government with its own elected board and its own budget vote. As the standard reference on New York’s administrative divisions puts it, school districts are rarely precisely coextensive with the cities, towns, villages, or hamlets that bear the same name.

On the North Shore, that abstraction has very concrete consequences. Here is the verified picture for the communities that generate the most confusion.

Community	Municipal status	School district(s) whose boundaries include it
Village of Roslyn	Village, North Hempstead	Roslyn UFSD, entirely
Village of Roslyn Estates	Village, North Hempstead	Roslyn UFSD, entirely
Village of East Hills	Village, North Hempstead and Oyster Bay	Roslyn UFSD, East Williston UFSD, Jericho UFSD
Village of Flower Hill	Village, North Hempstead	Manhasset UFSD, Port Washington UFSD, Roslyn UFSD
Village of Roslyn Harbor	Village, North Hempstead and Oyster Bay	Roslyn UFSD, North Shore CSD
Village of Old Westbury	Village, North Hempstead and Oyster Bay	East Williston UFSD, Jericho UFSD, Roslyn UFSD, Westbury UFSD
Village of Brookville	Village, Oyster Bay	Jericho UFSD primarily, portions Locust Valley CSD
Village of Sands Point	Village, North Hempstead	Port Washington UFSD
Village of Sea Cliff	Village, Oyster Bay	North Shore CSD
Roslyn Heights	Hamlet, North Hempstead	Roslyn UFSD for most, smaller portions East Williston UFSD and Herricks UFSD
Albertson	Hamlet, North Hempstead	Mineola UFSD, East Williston UFSD, Herricks UFSD, Roslyn UFSD
Greenvale	Hamlet, North Hempstead and Oyster Bay	Roslyn UFSD and North Shore CSD, split along the town line

As of July 2026. Compiled from published district service-area descriptions and municipal records. Districts listed are those whose boundaries include some part of the community; they are not assignments for any particular address. Assignment is parcel-specific and must be confirmed with the district registrar.

The Greenvale case: when a district line is a town line

Greenvale is the cleanest illustration on the North Shore. The hamlet is split between the Roslyn Union Free School District and the North Shore Central School District, and the boundary between them corresponds with the North Hempstead and Oyster Bay town line. Most of the hamlet is served by Roslyn. One layer happens to align with another here, which is exactly why people assume it happens everywhere. It does not.

The Flower Hill case: three ZIP codes, three districts, one village

The Village of Flower Hill sits entirely within the Town of North Hempstead, and is located within the boundaries of the Manhasset Union Free School District, the Port Washington Union Free School District, and the Roslyn Union Free School District. It uses three ZIP codes: 11030 for Manhasset, 11050 for Port Washington, and 11576 for Roslyn. One village, one town, three mailing identities, three districts. A buyer who filters a search by “Port Washington” or by ZIP code will see Flower Hill homes that are not in the district they assumed. This is significant enough that we built a dedicated page on it.

Where the schools actually sit

The names are misleading in the other direction too. The Roslyn Union Free School District serves the entirety of the Villages of Roslyn and Roslyn Estates, plus parts of the Villages of East Hills, Flower Hill, North Hills, and Roslyn Harbor, and parts of the hamlets of Greenvale and Roslyn Heights. Its five schools are located in Roslyn Heights and East Hills: Roslyn High School and the Roslyn Heights School in Roslyn Heights, and Roslyn Middle School, East Hills Elementary School, and Harbor Hill Elementary School in East Hills. Meanwhile the East Williston Union Free School District, which serves all of the Village of East Williston along with portions of Roslyn Heights, East Hills, Mineola, and Old Westbury, lists its administrative address at 11 Bacon Road in Old Westbury.

The Long Island Rail Road follows the same pattern. The station named Roslyn, on the Oyster Bay Branch between Albertson and Greenvale, is physically located in Roslyn Heights, at Lincoln Avenue and Railroad Avenue. No LIRR station sits inside the Village of Roslyn’s boundaries at all. The Oyster Bay Branch is electrified only as far east as East Williston, and diesel locomotive service runs beyond it. The Port Washington Branch, which serves Great Neck, Manhasset, Plandome, and Port Washington, runs west of Woodside to Penn Station or Grand Central Madison. Two branches, two very different commutes, both labeled “North Shore.”

How Do You Confirm the Jurisdictions for a Specific Address?

Four sources, in this order. Do not stop at the first one.

Start with the county parcel record

The Nassau County Land Records Viewer provides assessment roll data, district information, tax maps, property photographs, past taxes, tax rates, exemptions with amounts, and comparable sales. It is the fastest way to see which districts a parcel is coded into and what it has actually paid.

Confirm zoning and permit history with the right building department

If the parcel is inside a village, that is the village building department. If it is in an unincorporated hamlet, it is the Town of North Hempstead or the Town of Oyster Bay. Ask specifically for open permits and for certificates of occupancy on every structure, including additions, decks, pools, and finished basements.

Confirm the tax picture with the Receiver of Taxes and the village

The town Receiver of Taxes handles the county, town, school, and special district bills. If the property is in a village, request the village tax bill separately from the village clerk or treasurer. Only when you have both do you have the full annual picture.

Confirm school assignment with the district, in writing

This is the one that must come from the district registrar and must be in writing for the specific address. Do not rely on a ZIP code, a listing sheet, a school-rating website, or a neighbor. Boundaries can be redrawn, and portions of several North Shore communities sit in districts that share no name with the community.
