ADUs vs. short-term rentals in Deerpark
No local short-term-rental law on record - which is not the same as permission for Town of Deerpark. No local STR ordinance found as of Jun 2026. STRs appear permitted without specific local registration requirement. 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.
