Short-term rentals
Short-term rentals allowed with local rules. Short-term rentals are regulated under Article XIIIB of Zoning Chapter 235, added 9-16-2025 by L.L. No. 9-2025 and amended in 2026 by L.L. Nos. 5-2026 and 6-2026. § 235-76.50 states a general prohibition and § 235-76.52 then requires a permit, so the use is available only on the terms the article sets; § 235-76.51 presumes a dwelling unit is an STR from advertising and § 235-76.54 sets the operating standards. Because the article was amended twice in 2026, confirm the current text. 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 Irondequoit at (585) 336-6020 before listing.
