ADUs vs. short-term rentals in West Haverstraw
No local short-term-rental law on record - which is not the same as permission for Village of West Haverstraw. No local short-term-rental law found as of 2026-08-26. Zoning Chapter 250 does not address transient rental. Nothing in that chapter is short-term-rental specific, so it neither authorises nor forbids a short stay — but the permit obligation applies to rentals generally and should be assumed to apply. Absence of a found STR law is not permission. 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 West Haverstraw at (845) 947-2800 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.
