Short-term rentals
Short-term rentals allowed with local rules. Transient lodging requires a Town operating permit under Chapter 281, Transient and Nontransient Lodging, adopted 8-13-2019 by L.L. No. 3-2019. § 281-2 makes an operating permit a condition of continued use, with application, inspection and fee requirements at §§ 281-3 through 281-5. Westchester County's 3% hotel occupancy tax also applies to short stays. 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 Town of Cortlandt at (914) 734-1010 before listing.
