ADUs vs. short-term rentals in Pelham

No local short-term-rental law on record - which is not the same as permission for Village of Pelham. No local STR ordinance found for the Village of Pelham as of Jun 2026; standard village codes apply. 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.
