Buying in Washington Heights: the questions with sourced answers
Each answer is built from Washington Heights’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 Washington Heights?
Median year built in zip 10032: 1938 (Manhattan: 1951). Of 23,178 units, 62% predates 1940; 5% is from 2000 on. Next come the 1940s at 11% and the 1960s at 8%. 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: 105 years old. (ACS)
How are homes in Washington Heights heated? Is an oil tank likely?
45% utility gas, 27% electricity; fuel oil 21% against 15% county-wide. NYSDEC logs 1 petroleum spill at private homes in Washington Heights since 2008, 0 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 Washington Heights mostly houses or apartments, owned or rented?
46% buildings of 20 to 49 units, 34% buildings of 50 or more units, 12% buildings of 10 to 19 units; 8% owner-occupied (Manhattan: 25%). With 80% 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. Lou’s jobs here included a condominium. (ACS)
Is radon a concern in Washington Heights?
Manhattan (reported by borough): 131 basement tests, average 2.09 pCi/L, 16 at 4 or above (12%). First-floor tests there: 68, average 2.7. The highest basement reading was 49.5 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 Washington Heights flooded? Is the house in a flood zone?
4 flood-insurance claims from zip 10032 since 1978: 181st 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 Washington Heights?
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 Washington Heights compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Washington Heights (zip 10032) 1938, 21%, 8%; Highbridge (zip 10452): built 1955, oil 17%, 3% owner-occupied; Morris Heights (zip 10453): built 1954, oil 20%, 5% owner-occupied; Harlem (zip 10027): built 1943, oil 17%, 16% owner-occupied. (ACS)
Which code, water and sewer rules apply in Washington Heights?
The New York City Construction Codes, the NYC Department of Buildings records, NYC water and sewer and the offering-plan rules for co-ops and condos: county-wide, written once. They are the same for every town in Manhattan, so they are set out there with their sources instead of on each page.
How much does a home inspection in Washington Heights 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.
