What the Grand View-on-Hudson code indicates by district
The table below shows how each district treats ADUs, alongside the lot and setback standards that govern a second unit. District boundaries and conditions vary, so treat this as a starting point and confirm the district that applies to your parcel.

ADUs vs. short-term rentals in Grand View-on-Hudson
Short-term rentals prohibited for Village of Grand View-on-Hudson. Short-term rental is not an available use in Grand View-on-Hudson, on the face of the Zoning Law. Chapter VI-E is a closed list: 'Only those uses listed for each zone as being permitted shall be permitted. Any use not specifically listed as being permitted shall be deemed to be prohibited.' No lodging, transient-accommodation or rental use is listed in either zone; Chapter VI-B states there is no commercial or business district anywhere in the Village; Chapter VI-C bars occupancy by more than one family; and the Home Occupation definition in Chapter IV expressly excludes 'transient accommodations.' Note that this is the closed-list clause doing the work — the Village has no local law that names short-term rentals, so confirm with the Village at (845) 358-2919 before relying on it either way. Separately, since 2025 New York State requires every short-term-rental host to register the unit with the State through the county registry. 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.
