The typical Smithtown home was built in 1967, 3 years older than the Suffolk County median of 1970. Housing age matters for garage doors because it decides the opening size, whether the door still runs on extension springs, and how much headroom the track has.
Smithtown’s housing
The Smithtown hamlet’s homes are mostly from the 1960s on: median 1967, and only about 25% predate 1960 (Census). About 89% are detached, about 89% are owner-occupied, and the median value is about $705,000. About 34% of households have three or more vehicles, among the highest shares we track.
Smithtown vs its neighbors
Smithtown’s housing is newer than Commack’s next door: about 25% of Smithtown homes predate 1960 versus about 31% in Commack, and Smithtown’s median home is three years younger (1967 vs 1964). It’s much newer than Northport, where about 29% of homes predate 1940 compared with about 6% in Smithtown. In practice that means fewer extension-spring conversions here and more work on two-car torsion doors and their openers. At about 34% of households with three or more vehicles, against about 29% for Suffolk, doors here run more cycles than the county average, so ask about high-cycle springs (about $50 more per pair on one published Long Island list).
