Buying in Ossining: the questions with sourced answers
Each answer is built from Ossining’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 Ossining?
Median year built in zip 10562: 1962 (Westchester: 1958). Of 12,745 units, 31% predates 1940; 7% is from 2000 on. Next come the 1960s at 17% and the 1980s at 15%. 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: 29 years old. (ACS)
How are homes in Ossining heated? Is an oil tank likely?
48% utility gas, 33% fuel oil or kerosene; fuel oil 33% against 30% county-wide. NYSDEC logs 734 petroleum spills at private homes in Ossining since 1987, 212 since 2015. 26 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 Ossining mostly houses or apartments, owned or rented?
39% detached houses, 14% buildings of 50 or more units, 12% attached single-family houses; 61% owner-occupied (Westchester: 62%). Two- to four-unit buildings are 19%; a multi-family house means shared systems, separate meters and what each unit controls. Lou’s jobs here included a townhouse. (ACS)
Is radon a concern in Ossining?
Town of Ossining: 83 basement tests, average 2.12 pCi/L, 10 at 4 or above (12%). Westchester: 18% of 2,826. First-floor tests there: 34, average 0.71. On the share at 4 or above, it ranks 20th of the county’s 23 towns and cities. The highest basement reading was 10.9 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 Ossining flooded? Is the house in a flood zone?
90 flood-insurance claims from zip 10562 since 1978, most in 1999 (21): 77th 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 Ossining?
The Village of Ossining 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 Ossining compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Ossining (zip 10562) 1962, 33%, 61%; Croton-on-Hudson (zip 10520): built 1961, oil 34%, 69% owner-occupied; Chappaqua (zip 10514): built 1965, oil 48%, 88% owner-occupied; Briarcliff Manor (zip 10510): built 1970, oil 25%, 82% owner-occupied. (ACS)
Which code, water and sewer rules apply in Ossining?
The New York State Uniform Code, the local water suppliers and the county rule on testing private wells at sale: county-wide, written once. They are the same for every town in Westchester, so they are set out there with their sources instead of on each page.
How much does a home inspection in Ossining 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.
