ADUs vs. short-term rentals in Croton-on-Hudson
Short-term rentals allowed with registration for Village of Croton-on-Hudson. A short-term rental requires Village registration. Chapter 186 defines a SHORT-TERM RENTAL at § 186-4 and includes it in RENTAL UNIT, and § 186-11 provides for a short-term rental unit certificate on a term distinct from an ordinary rental unit registration. Village Resolution 294-2025, adopted 12-17-2025, set the rental-registry fees and prices the short-term rental unit separately from the triennial $25 ordinary rental unit. Westchester County's 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 Village of Croton-on-Hudson at (914) 271-4783 before listing. 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.
