Buying in Montauk: the questions with sourced answers
Each answer is built from Montauk’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 Montauk?
Median year built in zip 11954: 1978 (Suffolk County: 1970). Of 4,565 units, the 1980s built the most, 25%; 11% is from 2000 on. Next come the 1970s at 23% and the 1960s at 12%. 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: 45 years old. (ACS)
How are homes in Montauk heated? Is an oil tank likely?
45% fuel oil or kerosene, 23% bottled or tank gas; fuel oil 45% against 45% county-wide. NYSDEC logs 92 petroleum spills at private homes in Montauk since 1989, 33 since 2015. 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 Montauk mostly houses or apartments, owned or rented?
72% detached houses, 4% attached single-family houses; 81% 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 Montauk?
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 Montauk flooded? Is the house in a flood zone?
240 flood-insurance claims from zip 11954 since 1978, most in 2012 (72): 54th 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 Montauk?
The Town of East Hampton 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 Montauk compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Montauk (zip 11954) 1978, 45%, 81%; Amagansett (zip 11930): built 1983, oil 62%, 84% owner-occupied; East Hampton (zip 11937): built 1980, oil 50%, 77% owner-occupied; Hampton Bays (zip 11946): built 1975, oil 64%, 78% owner-occupied. (ACS)
Which code, water and sewer rules apply in Montauk?
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 Montauk 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.
