ADUs vs. short-term rentals in Callicoon
Short-term rentals allowed with local rules for Town of Callicoon. Short-term rentals require an annual Town permit. 179. The chapter's stated purpose is to enable the Town to monitor short-term residential rentals, it defines them as properties used as short-term transient rentals, and it requires the homeowner to keep records of rental dates and guest numbers. It also provides that a short-term rental may not adversely affect the residential character of the neighborhood — no advertising sign, no unreasonable noise. A permit is issued subject to approval by the Code Enforcement Officer, with a safety inspection; occupancy is not capped generally but the maximum must be declared on the application. 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 Callicoon at (845) 482-5390 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.
