Buying in Hartsdale: the questions with sourced answers
Each answer is built from Hartsdale’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 Hartsdale?
Median year built in zip 10530: 1959 (Westchester: 1958). Of 6,795 units, the 1950s built the most, 35%; 1% is from 2000 on. Next come the 1960s at 26% and the 1970s at 11%. 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: 58 years old. (ACS)
How are homes in Hartsdale heated? Is an oil tank likely?
49% utility gas, 24% fuel oil or kerosene; fuel oil 24% against 30% county-wide. NYSDEC logs 206 petroleum spills at private homes in Hartsdale since 1992, 42 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 Hartsdale mostly houses or apartments, owned or rented?
36% detached houses, 34% buildings of 50 or more units, 8% buildings of 20 to 49 units; 86% owner-occupied (Westchester: 62%). With 42% of units in buildings of 20 or more, many purchases here are apartments: the inspection covers the unit, and the roof, plant and risers belong to the board. (ACS)
Is radon a concern in Hartsdale?
Town of Greenburgh: 258 basement tests, average 2.23 pCi/L, 25 at 4 or above (10%). Westchester: 18% of 2,826. First-floor tests there: 89, average 0.89. On the share at 4 or above, it ranks 22nd of the county’s 23 towns and cities. The highest basement reading was 21.8 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 Hartsdale flooded? Is the house in a flood zone?
102 flood-insurance claims from zip 10530 since 1978, most in 1980 (18): 72nd 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 Hartsdale?
The Town of Greenburgh 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 Hartsdale compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Hartsdale (zip 10530) 1959, 24%, 86%; Ardsley (zip 10502): built 1959, oil 21%, 84% owner-occupied; White Plains (zip 10606): built 1961, oil 25%, 38% owner-occupied; Scarsdale (zip 10583): built 1953, oil 17%, 85% owner-occupied. (ACS)
Which code, water and sewer rules apply in Hartsdale?
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 Hartsdale 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.
