Vacation rentals must shut down by order of the County.

"County officials say these short-term rentals must cease operations immediately; bookings for the foreseeable future must be canceled; no new arrivals may be processed; no reservations should be accepted until the state and county’s orders are rescinded; and any guests currently in rentals must be told to return home. Violation of state and county health orders are crimes punishable by fines, imprisonment, or both."
