ADUs vs. short-term rentals in Wappingers Falls

Short-term rentals allowed with local rules for Village of Wappingers Falls. Only a hosted short-term rental is allowed: the resident must live in the detached single-family house as a primary residence and be there during the rental.

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.
