The three faces of 11978
The zip code is not one market. It is a mainland village wrapped around a downtown, connected by two drawbridges to a barrier island that a separate set of insurance and construction rules governs, with a third, smaller village incorporated entirely on its own sitting further west on that same strip of sand.
| Sub-area | Price signal (sourced comps) | Flood and governance profile | Typical buyer |
|---|---|---|---|
| Village core (mainland) | New-construction 4-bedroom homes have sold near $815 to $863 per square foot; a 5-bedroom new build closed near $3.25M, per Homes.com sold-listing records | Mostly outside FEMA’s highest-hazard zones; standard flood coverage still worth pricing before closing | Primary residence, family relocation |
| Dune Road barrier island, within the Village of Westhampton Beach | Waterfront condos have closed as high as $1,336 per square foot (Homes.com) | FEMA Zone VE or AE per FEMA’s coastal flood-map guidance: pilings construction required in VE, fill prohibited, NFIP purchase mandatory with a federally backed mortgage | Seasonal or investment buyer, cash-heavy |
| Quiogue and West Hampton Dunes fringe, west end of the barrier island | Thinner comp set, smaller and older housing stock | Partly governed by a separate incorporated village, West Hampton Dunes (population 126 in the 2020 census), with its own building code and beach-nourishment assessments | Buyer specifically seeking barrier-island exposure at a discount to Westhampton Beach proper |
The practical consequence: two listings both addressed “Westhampton Beach, NY 11978” can be a mainland Cape on municipal sewer service and a piling-built oceanfront condo under an entirely different village government. The zip code doesn’t distinguish them. The deed and the flood map do.
What the market data disagree about
Four independent data providers, covering overlapping but not identical geographies, currently disagree with each other by hundreds of thousands of dollars on the same village.
| Snapshot | Geography | Median price | Price per sq ft | Days on market | Sales in period |
|---|---|---|---|---|---|
| March 2026 (Redfin) | Village | $1.0M | $455 | 252 | 1 |
| March 2026 (Movoto) | Village | $1,337,000 | — | 139 | 81 |
| Full-year 2025 (Suffolk Vision, via Raveis) | Hamlet cluster | $1,625,026 | — | — | 309 |
| December 2024 (Rocket Homes) | Village | $1.8M list | $792 | 141 avg. listing age | 5 |
A buyer or seller reading a single month’s median for 11978 should ask what geography and what sample size produced it before treating the figure as a market signal, and should weight a full-year number like the $1.6 million hamlet median far more heavily than any one month’s swing.
Who lives here, and how much of the year
The 2020 Decennial Census recorded a year-round village population in the low 2,000s, according to the U.S. Census Bureau’s village profile. Separately, Census-sourced housing data compiled by Point2Homes puts village-wide vacancy at 57.9% of all housing units, a figure close enough to an independent third-party estimate of 55.1% cited in the prior competitive analysis that both numbers can be treated as roughly reliable: well over half the housing stock in the village sits empty most of the year.
Is Westhampton Beach a year-round town or a summer town?
Both, unevenly. A small year-round population shares the village with a housing stock where more than half the units are second-home or seasonal inventory. Winter services thin out substantially between Labor Day and Memorial Day, and an investor modeling rental income should plan around a compressed high season rather than steady year-round occupancy.
Downtown and daily life
Main Street runs through a downtown the Village rebuilt from the ground up. A $11 million reconstruction broke ground in September 2019, replacing 2,100 feet of failing roadway and drainage with two traffic circles, undergrounded utilities, and permeable pavers, and stood substantially complete by the following spring, according to 27east’s coverage of the project’s later engineering award. The Village followed that with an $11.1 million sewer collection system, which broke ground under Mayor Maria Moore on April 23, 2021, targeted for completion in September 2022 and projected to cut nitrogen loading into Moniebogue Bay by roughly 5,000 pounds a year, per the Village’s own groundbreaking announcement. The result is a downtown that can now support restaurant and apartment uses the old cesspool-dependent infrastructure couldn’t.
Schools
The Westhampton Beach Union Free School District runs one K-12 campus and enrolls roughly 1,800 students, but its catchment isn’t the whole zip code and it isn’t uniform. The district’s own site lists the villages of Westhampton Beach and Quogue and the hamlets of Westhampton, East Quogue, Quiogue, Remsenburg-Speonk, and East Moriches as its service area, and Quogue’s own district runs an elementary school through grade 6 before its students transfer into Westhampton Beach for grades 7 through 12 under a tuition arrangement. An address inside the Village of Quogue’s boundary, even carrying an 11978 or adjacent zip, sends a five-year-old to a different building than an address inside the Village of Westhampton Beach itself.
Does every 11978 address feed the Westhampton Beach schools?
Not for the earliest grades. Quogue-zoned children attend Quogue’s own elementary school through sixth grade, then transfer into Westhampton Beach for grades 7 through 12 on a tuition basis. Confirm the specific elementary assignment for any address before assuming it matches the middle and high school district.
Getting there
Long Island Rail Road’s Westhampton stop sits on the Montauk Branch, roughly 78 miles east of New York City. Trains from this stop don’t run directly to Grand Central or Penn Station; every rider transfers at Jamaica or Babylon, according to the MTA’s own service description.
Flood risk and insurance on the barrier island
FEMA maps the immediate oceanfront on barrier islands like this one as Zone VE, where wave action requires homes to be built on pilings and prohibits building on fill, or Zone AE, where flood risk is high but wave energy is lower, per FEMA’s own coastal mapping guidance. Both zones carry a mandatory flood-insurance purchase requirement for any federally backed mortgage, on top of the elevated construction cost pilings impose.
This isn’t a theoretical risk here. In December 1992, a week-long nor’easter opened a new inlet through the barrier island; the Army Corps of Engineers’ own account puts roughly 80 houses under water, with others cut off entirely when the new inlet severed the only access road. Further west on the same spit, damage was severe enough, and the legal fight over who was responsible for rebuilding the beach was bitter enough, that the affected owners incorporated their own village, West Hampton Dunes, in 1993, specifically to force a federally funded beach-restoration program. That village still governs part of the barrier island inside this same zip code, separately from the Village of Westhampton Beach.
Dune Road pricing reflects two separate variables buyers need to underwrite individually: the specific parcel’s FEMA flood zone, which sets the insurance bill, and its governing village, which sets the local beach-maintenance assessment.
Is Dune Road a safe long-term investment given its flood history?
That depends on the specific parcel’s flood zone and elevation, not on Dune Road as a category. A piling-built home in a mapped VE zone meets current federal construction standards for wave action; an older, non-elevated structure in the same zone may face higher insurance costs or future retrofit requirements. Run the address through FEMA’s Flood Map Service Center before making an offer.
Common mistakes when searching “11978”
- Treating the zip code as the village. The Village of Westhampton Beach has its own boundary; 11978 also covers Quiogue and part of West Hampton Dunes, each under different governance and price bands.
- Assuming one price band applies zip-wide. A mainland Cape and a Dune Road piling-built condo can both carry an 11978 address and differ by a factor of three in price per square foot.
- Estimating rental yield without accounting for seasonal vacancy. With more than half the housing stock sitting empty most of the year, a straight-line annual rent projection overstates what a summer-only rental actually earns.
Is 11978 the same as the Village of Westhampton Beach?
No. The zip code is a USPS delivery boundary; it extends into Quiogue and part of the separately incorporated Village of West Hampton Dunes. A property can carry an 11978 address without sitting inside the Village of Westhampton Beach’s own municipal boundary.
Who this zip code suits
A family buying a primary residence is generally better served by the village core, where the school assignment is unambiguous and the flood-insurance bill is lower. An investor specifically underwriting the barrier island’s discount pricing needs to price in West Hampton Dunes’ separate governance and assessment structure as part of the deal, not discover it at closing.
