ADUs vs. short-term rentals in Stony Point
Short-term rentals prohibited for Town of Stony Point. Prohibited. Stony Point bars rentals of less than 29 days in its residential zones, and transient rental of a dwelling unit is not an enumerated permitted use in any district under Chapter 215; the Town has no registry or permit pathway. Source: Rockland County Business Journal municipality-by-municipality summary of local STR rules (Jan 2025). Confirm current status with the Building Department at (845) 786-2716 before listing a property. Separately, since 2025 New York State requires every short-term-rental host to register the unit with the State through the county registry, regardless of what the municipality allows. 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.
