Buying in Chappaqua: the questions with sourced answers
Each answer is built from Chappaqua’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 Chappaqua?
Median year built in zip 10514: 1965 (Westchester: 1958). Of 4,205 units, 24% predates 1940; 9% is from 2000 on. Next come the 1960s at 15% 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: 39 years old. (ACS)
How are homes in Chappaqua heated? Is an oil tank likely?
48% fuel oil or kerosene, 37% utility gas; fuel oil 48% against 30% county-wide. NYSDEC logs 973 petroleum spills at private homes in Chappaqua since 1986, 225 since 2015. 32 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 Chappaqua mostly houses or apartments, owned or rented?
84% detached houses, 6% attached single-family houses, 4% buildings of 5 to 9 units; 88% owner-occupied (Westchester: 62%). Detached houses dominate, so most inspections here run from the roof to the foundation of one building. Lou’s jobs here included a townhouse. (ACS)
Is radon a concern in Chappaqua?
Town of New Castle: 149 basement tests, average 2.27 pCi/L, 18 at 4 or above (12%). Westchester: 18% of 2,826. First-floor tests there: 33, average 1.1. On the share at 4 or above, it ranks 19th of the county’s 23 towns and cities. The highest basement reading was 31.7 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 Chappaqua flooded? Is the house in a flood zone?
144 flood-insurance claims from zip 10514 since 1978, most in 1980 (31): 63rd 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 Chappaqua?
The Town of New Castle Building Division (Development Department). Chappaqua is an unincorporated hamlet of New Castle. 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 Chappaqua compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Chappaqua (zip 10514) 1965, 48%, 88%; Pleasantville (zip 10570): built 1960, oil 41%, 86% owner-occupied; Ossining (zip 10562): built 1962, oil 33%, 61% owner-occupied; Briarcliff Manor (zip 10510): built 1970, oil 25%, 82% owner-occupied. (ACS)
Which code, water and sewer rules apply in Chappaqua?
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 Chappaqua 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.
