ADUs vs. short-term rentals in Peekskill
No local short-term-rental law on record - which is not the same as permission for City of Peekskill. A proposed STR ordinance was withdrawn after significant public opposition from hosts; no local STR ordinance found as of Jun 2026, though standard zoning and housing codes apply.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.
