Buying in Williston Park: the questions with sourced answers
Each answer is built from Williston Park’s own rows in public data — the Census, NYSDOH, NYSDEC, FEMA, the office that holds the permits — or from Lou’s reports, and cites its source. Data retrieved 1 November 2026.
How old are the houses in Williston Park?
Median year built in zip 11596: 1942 (Nassau County: 1955). Of 3,450 units, 46% predates 1940; 3% is from 2000 on. Next come the 1940s at 16% and the 1950s at 16%. An older house is not a worse house, but its wiring, plumbing and roof were installed under different rules and replaced piecemeal, which is what the inspection looks for. (ACS)
How are homes in Williston Park heated? Is an oil tank likely?
81% utility gas, 13% fuel oil or kerosene; fuel oil 13% against 28% county-wide. NYSDEC logs 47 petroleum spills at private homes in Williston Park since 1991, 10 since 2015. A gas conversion can leave a tank behind. An abandoned tank is most likely in a house that was converted from oil. Buried tanks are outside the standards New York sets for a home inspection, so the seller’s answer matters. (ACS, NYSDEC)
Is Williston Park mostly houses or apartments, owned or rented?
80% detached houses, 8% buildings of 50 or more units, 7% two-unit buildings; 83% owner-occupied (Nassau County: 82%). Detached houses dominate, so most inspections here run from the roof to the foundation of one building. (ACS)
Is radon a concern in Williston Park?
Town of North Hempstead: 194 basement tests, average 1.65 pCi/L, 16 at 4 or above (8%). Nassau County: 6% of 837. First-floor tests there: 48, average 0.88. On the share at 4 or above, it ranks 3rd of the county’s 5 towns and cities. The highest basement reading was 7.5 pCi/L. EPA’s action level is 4 pCi/L, and it advises testing every home whatever the area’s results. Radon testing is optional. (NYSDOH)
Has Williston Park flooded? Is the house in a flood zone?
12 flood-insurance claims from zip 11596 since 1979, most in 1983 (3): 167th of the 189 zips on these pages. A claim count describes the zip, not the house. Flood zones follow the address. Check the address on FEMA’s map. (OpenFEMA)
Who holds the permits and certificate of occupancy in Williston Park?
The Village of Williston Park Building Department. Your attorney usually runs the search. The inspection reports the condition of what is there and flags work that typically needs a permit, such as a finished basement, a dormer or a moved panel, so you know what to ask about.
How does Williston Park compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Williston Park (zip 11596) 1942, 13%, 83%; Mineola (zip 11501): built 1954, oil 21%, 66% owner-occupied; Roslyn Heights (zip 11577): built 1954, oil 22%, 93% owner-occupied; Carle Place (zip 11514): built 1954, oil 19%, 76% owner-occupied. (ACS)
Which code, water and sewer rules apply in Williston Park?
The New York State Uniform Code, groundwater from 46 public water systems, the county sewer-connection rule and the Article XI heating-oil tank closure program: county-wide, written once. They are the same for every town in Nassau County, so they are set out there with their sources instead of on each page.
How much does a home inspection in Williston Park cost, and how fast is the report?
Lou quotes the actual property, not a flat rate — what drives the price is size, age and what is included. The written report arrives the same day as a rule; a large or complex house can run to the next morning. Call or text 516-330-3870.
