Short-term rentals
Short-term-rental status not confirmed. Short-term rental rules in Canaan are not confirmed. The zoning law's silence on short-term rentals is not permission, and a separate STR law had a public hearing in March 2025; ask the Town whether it passed and what applies before counting on the use.
Conditions the code attaches:
- The zoning law treats a bed and breakfast as an owner-occupied single-family dwelling serving no more than ten transient lodgers, with a special permit needed at three or more rooms.
- New York State's 2025 short-term rental registry requires every host to register the unit, regardless of local law.
- Confirm with the Town of Canaan at (518) 781-3144 before listing.
