ADUs vs. short-term rentals in Haverstraw
Short-term rentals allowed with local rules for Village of Haverstraw. Regulated, not freely permitted. The Village of Haverstraw REQUIRES short-term rentals to be registered and prohibits short-term rentals aggregating more than 90 days in any calendar year. NOTE: the surrounding Town of Haverstraw is a separate jurisdiction and PROHIBITS short-term rentals outright — do not conflate the two. Source: Rockland County Business Journal municipality-by-municipality summary of local STR rules (Jan 2025). Confirm the current registration requirements with the Building Department at (845) 429-0300 before listing a property. Separately, since 2025 New York State requires every short-term-rental host to register the unit with the State through the county registry, regardless of what the municipality allows. 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.
