Buying in Carle Place: the questions with sourced answers
Each answer is built from Carle Place’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 Carle Place?
Median year built in zip 11514: 1954 (Nassau County: 1955). Of 1,758 units, the 1950s built the most, 46%; 6% is from 2000 on. Next come the 1940s at 26% and the 1960s at 7%. 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: 18 years old. (ACS)
How are homes in Carle Place heated? Is an oil tank likely?
74% utility gas, 19% fuel oil or kerosene; fuel oil 19% against 28% county-wide. NYSDEC logs 44 petroleum spills at private homes in Carle Place since 1993, 18 since 2015. 5 were logged in 2012, the year of Hurricane Sandy. A gas conversion can leave a tank behind. An abandoned tank is most likely in a house that was converted from oil. Buried tanks are outside the standards New York sets for a home inspection, so the seller’s answer matters. (ACS, NYSDEC)
Is Carle Place mostly houses or apartments, owned or rented?
75% detached houses, 10% buildings of 20 to 49 units, 7% two-unit buildings; 76% owner-occupied (Nassau 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 Carle Place?
Town of North Hempstead: 194 basement tests, average 1.65 pCi/L, 16 at 4 or above (8%). Nassau County: 6% of 837. First-floor tests there: 48, average 0.88. On the share at 4 or above, it ranks 3rd of the county’s 5 towns and cities. The highest basement reading was 7.5 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 Carle Place flooded? Is the house in a flood zone?
14 flood-insurance claims from zip 11514 since 2007: 163rd 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 Carle Place?
The Town of North Hempstead Department of Building, Safety, Inspection & 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 Carle Place compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Carle Place (zip 11514) 1954, 19%, 76%; Mineola (zip 11501): built 1954, oil 21%, 66% owner-occupied; Williston Park (zip 11596): built 1942, oil 13%, 83% owner-occupied; Garden City (zip 11530): built 1950, oil 14%, 89% owner-occupied.

Which code, water and sewer rules apply in Carle Place?
The New York State Uniform Code, groundwater from 46 public water systems, the county sewer-connection rule and the Article XI heating-oil tank closure program: county-wide, written once. They are the same for every town in Nassau County, so they are set out there with their sources instead of on each page.
How much does a home inspection in Carle Place 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.
