ADUs vs. short-term rentals in Hoosick Falls
No local short-term-rental law on record - which is not the same as permission for Village of Hoosick Falls. No local short-term-rental law found for Village of Hoosick Falls as of 2026-08-05; absence of a found law is not permission. Separately, New York State's 2025 STR registry (Ch. 99 of the Laws of 2025) requires every host statewide to register the unit through the Rensselaer County registry regardless of what the municipality allows. Confirm with the building department at (518) 686-7072 before listing. These are separate questions from whether you can build an ADU — a unit you're allowed to add isn't automatically one you're allowed to rent nightly, so check both.
