Short-term rentals
No local short-term-rental law on record - which is not the same as permission. Rush has no local short-term rental law. That is not permission: the zoning code prohibits any use its closed use list does not name, so confirm with Code Enforcement before counting on a short-term rental.
Conditions the code attaches:
- § 120-7C prohibits all uses not specifically permitted in R-20, and the other residential districts adopt the R-20 list.
- A bed-and-breakfast is an owner-present lodging use on a Planning Board special permit and does not cover a whole-house short-term rental in a residential district.
- New York State's 2025 short-term rental registry requires every host to register, whatever the local law.
- Code Enforcement can be reached at (585) 533-1312.
