ADUs vs. short-term rentals in Warwick
Short-term rentals allowed with local rules for Village of Warwick. Local Law 7 of 2024 added Chapter 115 Short-Term Rentals (effective ~Jan 2025); STR requires a permit, and non-owner-occupied STRs require a Special Use Permit. 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.
