ADUs vs. short-term rentals in Wawayanda
Short-term rentals allowed with local rules for Town of Wawayanda. Wawayanda regulates short-term rentals under a December 2024 local law amending its zoning, and a short-term rental establishment needs an operating permit. 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.
