Buying in Williamsbridge: the questions with sourced answers
Each answer is built from Williamsbridge’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 Williamsbridge?
Median year built in zip 10466: 1952 (Bronx: 1954). Of 26,303 units, 35% predates 1940; 6% is from 2000 on. Next come the 1950s at 21% and the 1960s at 14%. 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. (ACS)
How are homes in Williamsbridge heated? Is an oil tank likely?
59% utility gas, 19% fuel oil or kerosene; fuel oil 19% against 24% county-wide. NYSDEC logs Bronx home oil spills under the borough, not Williamsbridge. 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 Williamsbridge mostly houses or apartments, owned or rented?
20% two-unit buildings, 18% detached houses, 14% attached single-family houses; 41% owner-occupied (Bronx: 20%). Two- to four-unit buildings are 33%; a multi-family house means shared systems, separate meters and what each unit controls. Lou’s jobs here included a two-family house. (ACS)
Is radon a concern in Williamsbridge?
Bronx (reported by borough): 101 basement tests, average 1.73 pCi/L, 8 at 4 or above (8%). First-floor tests there: 43, average 1.13. The highest basement reading was 20.9 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 Williamsbridge flooded? Is the house in a flood zone?
36 flood-insurance claims from zip 10466 since 1979, most in 2007 (6): 119th 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 Williamsbridge?
The NYC Department of Buildings. Look the address up on BIS or DOB NOW. 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 Williamsbridge compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Williamsbridge (zip 10466) 1952, 19%, 41%; Woodlawn (zip 10470): built 1945, oil 28%, 43% owner-occupied; Pelham Manor (zip 10803): built 1938, oil 21%, 81% owner-occupied; Kingsbridge (zip 10463): built 1955, oil 20%, 35% owner-occupied. (ACS)
Which code, water and sewer rules apply in Williamsbridge?
The New York City Construction Codes, the NYC Department of Buildings records and NYC water and sewer: county-wide, written once. They are the same for every town in Bronx, so they are set out there with their sources instead of on each page.
How much does a home inspection in Williamsbridge 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.
