ADUs vs. short-term rentals in Wappingers Falls

Short-term rentals allowed with local rules for Village of Wappingers Falls. Short-term rentals require a Village permit under Chapter 124, Short-Term Rentals, adopted 12-13-2023 by L.L. No. 3-2023. § 124-3 requires the permit, § 124-4 sets its term and §§ 124-5 through 124-7 govern application, renewal and issuance. New York State's 2025 short-term rental registry (Ch. 99 of the Laws of 2025) separately requires every host statewide to register the unit regardless of local law. Confirm with Village of Wappingers Falls at (845) 297-8773 before listing.
