Buying in Saint James: the questions with sourced answers
Each answer is built from Saint James’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 Saint James?
Median year built in zip 11780: 1973 (Suffolk County: 1970). Of 5,907 units, the 1960s built the most, 20%; 9% is from 2000 on. Next come the 1980s at 18% and the 1970s at 18%. 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: 60 years old. (ACS)
How are homes in Saint James heated? Is an oil tank likely?
43% fuel oil or kerosene, 35% utility gas; fuel oil 43% against 45% county-wide. NYSDEC logs 142 petroleum spills at private homes in Saint James since 1988, 49 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 Saint James mostly houses or apartments, owned or rented?
77% detached houses, 10% attached single-family houses, 7% buildings of 5 to 9 units; 87% owner-occupied (Suffolk 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 Saint James?
Town of Smithtown: 64 basement tests, average 2.94 pCi/L, 8 at 4 or above (13%). Suffolk County: 8% of 576. First-floor tests there: 18, average 1.01. On the share at 4 or above, it ranks 1st of the county’s 10 towns and cities. The highest basement reading was 42.6 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 Saint James flooded? Is the house in a flood zone?
67 flood-insurance claims from zip 11780 since 1978, most in 2012 (17): 88th of the 189 zips on these pages. A claim count describes the zip, not the house; 2012 was the year of Hurricane Sandy. Flood zones follow the address. Check the address on FEMA’s map. (OpenFEMA)
Who holds the permits and certificate of occupancy in Saint James?
The Town of Smithtown 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 Saint James compare with the towns around it?
By median year built, fuel-oil share and owner-occupancy: Saint James (zip 11780) 1973, 43%, 87%; Stony Brook (zip 11790): built 1965, oil 52%, 90% owner-occupied; East Setauket (zip 11733): built 1969, oil 50%, 85% owner-occupied; Kings Park (zip 11754): built 1967, oil 39%, 86% owner-occupied. (ACS)
Which code, water and sewer rules apply in Saint James?
The New York State Uniform Code, the Suffolk County Water Authority and private wells, and the Sanitary Code rules on cesspools (no in-kind replacement since 2017) and I/A septic systems: county-wide, written once. They are the same for every town in Suffolk County, so they are set out there with their sources instead of on each page.
How much does a home inspection in Saint James 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.
