Buying in East Hampton: the questions with sourced answers
Each answer is built from East Hampton’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 East Hampton?
Median year built in zip 11937: 1980 (Suffolk County: 1970). Of 14,277 units, the 1980s built the most, 20%; 18% is from 2000 on. Next come the 1970s at 20% and the 1990s at 13%. 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. Lou’s reports here: 31 years old. (ACS)
How are homes in East Hampton heated? Is an oil tank likely?
50% fuel oil or kerosene, 25% bottled or tank gas; fuel oil 50% against 45% county-wide. NYSDEC logs 405 petroleum spills at private homes in East Hampton since 1984, 154 since 2015. 13 were logged in 2012, the year of Hurricane Sandy. Ask about a tank, and for closure papers. A tank can be buried in the yard or sit in the basement, and a removed one should come with paperwork. Buried tanks are outside the standards New York sets for a home inspection, so the seller’s answer matters. (ACS, NYSDEC)
Is East Hampton mostly houses or apartments, owned or rented?
90% detached houses; 77% owner-occupied (Suffolk 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 East Hampton?
Town of East Hampton: 20 basement tests, average 1.53 pCi/L, 2 at 4 or above (10%). Suffolk County: 8% of 576. First-floor tests there: 7, average 0.56. On the share at 4 or above, it ranks 4th of the county’s 10 towns and cities. The highest basement reading was 4.7 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 East Hampton flooded? Is the house in a flood zone?
354 flood-insurance claims from zip 11937 since 1978, most in 2012 (79): 43rd of the 189 zips on these pages. A claim count describes the zip, not the house; 2012 was the year of Hurricane Sandy. Flood zones follow the address. Check the address on FEMA’s map. (OpenFEMA)
Who holds the permits and certificate of occupancy in East Hampton?
The Village of East Hampton Building Department & Code Enforcement. 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 East Hampton compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: East Hampton (zip 11937) 1980, 50%, 77%; Amagansett (zip 11930): built 1983, oil 62%, 84% owner-occupied; Montauk (zip 11954): built 1978, oil 45%, 81% owner-occupied; Hampton Bays (zip 11946): built 1975, oil 64%, 78% owner-occupied. (ACS)
Which code, water and sewer rules apply in East Hampton?
The New York State Uniform Code, the Suffolk County Water Authority and private wells, and the Sanitary Code rules on cesspools (no in-kind replacement since 2017) and I/A septic systems: county-wide, written once. They are the same for every town in Suffolk County, so they are set out there with their sources instead of on each page.
How much does a home inspection in East Hampton 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.
