ADUs vs. short-term rentals in Port Jervis
Short-term rentals allowed with local rules for City of Port Jervis. Transient occupancy regulated via use categories in Zoning Ch. 535: 'tourist home' (≤4 rooms, §535-4) and B&B/tourist accommodations (§535-37); 'dwelling unit' excludes transient occupancy. Amended through L.L. 4-2024. 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.
