ADUs vs. short-term rentals in Greece
Short-term rentals allowed with local rules for Town of Greece. Short-term rentals require a Town permit under § 162A-7 of Chapter 162A, Rental Properties — the Rental Properties Law of the Town of Greece, adopted 4-15-2014 by L.L. No. 2-2014 and amended in its entirety 7-15-2014 by L.L. No. 4-2014. The chapter carries a general rental property permit at § 162A-4 and a distinct short-term rental property permit at § 162A-7, with enforcement presumptions at § 162A-8. The requirement sits outside Zoning Chapter 211, which is why a zoning-only search misses it. 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 Greece at (585) 723-2443 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.
