Bay Shore’s mixed housing
Bay Shore covers a lot of ground, from older homes near the bay to postwar and later subdivisions to the north. The Census shows the mix: the median home dates to 1965, about 15% predate 1940, about 54% are single-family detached, and about 63% are owner-occupied. About 11% of households have no vehicle.
What that means for garage doors
- Older homes near the water often have detached garages, narrow openings and salt-worn hardware.
- Postwar and later homes inland have attached single and two-car garages with standard doors.
- Multi-family and rental properties sometimes have shared or older garages that need repair-first decisions.

Homes close to the Great South Bay see more salt in the air, which speeds up rust on cables, springs and bottom brackets.
