ADUs vs. short-term rentals in Wesley Hills
Short-term-rental status not confirmed for Village of Wesley Hills. Short-term rental status not confirmed for the Village of Wesley Hills — Chapter 230 does not address transient rental, and no separate local STR law was found in a 2026-07-21 search of village and county sources. Absence of a found law is NOT permission: call the Building Department at (845) 354-0400 to confirm 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.
