ADUs vs. short-term rentals in Montebello
Short-term rentals restricted for Village of Montebello. Restricted — a short-term rental is not an as-of-right use. Village Code Ch. 104-1 (amended 2-18-2021 by L.L. No. 1-2021) makes it unlawful to rent rooms to TRANSIENT occupants without a license from the Village Clerk-Treasurer, and that license cannot issue until the Planning Board grants a Special Permit under Ch. 195. Rentals to NONTRANSIENT occupants for 30 days or more do not require the license — so the practical effect is that stays under 30 days need a special permit. Verified against the Village Code 2026-07-21. Confirm with the Building Department at (845) 368-2211 before listing a property. Separately, since 2025 New York State requires every short-term-rental host to register the unit with the State through the county registry, regardless of what the municipality allows. 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.
