ADUs vs. short-term rentals in Perinton
Short-term rentals prohibited for Town of Perinton. Short-term rentals are BANNED IN EVERY RESIDENTIAL DISTRICT. § 208-28.3B, added 11-6-2024 by L.L. No. 5-2024 and amended 8-3-2026 by L.L. No. 5-2026, prohibits short-term rentals in all Apartment, Townhouse, Industrial, Planned Development District and residential zoning districts. They are available only in a Restricted Business, Commercial or Mixed Use District, and there only with a building permit and certificate. A bed-and-breakfast is a separate use under § 208-28.3A and needs a special permit from the Board of Appeals after a public hearing. 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 Perinton at (585) 223-0770 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.
