Sullivan County, NY Short-Term Rentals: Short-Term Rental Permits (2026)

Section 182-27 of the Sullivan County Code requires every operator, including short-term rental hosts, to file an application for a certificate of authority with the Treasurer within three days of commencing or opening for business. The application must identify the unit, the operator's name, address and taxpayer identification number, and, for an out-of-state corporation, the date it obtained authority to do business in New York. The Treasurer issues the certificate, which the operator must display prominently so occupants and prospective guests can see it, and the certificate cannot be assigned or transferred; it must be surrendered to the Treasurer when the business closes or the property is sold.

Registration is valid for two years and must be renewed in January, and a short-term rental host must display the current registration number on every listing, offering or advertisement, including on online booking platforms. Listing or offering a unit as a short-term rental without a current, valid registration is unlawful and makes the person who listed it ineligible for registration for 12 months from the date the violation is determined. To operate lawfully, § 182-27D also requires the dwelling to be registered, to post an evacuation diagram and emergency phone numbers, to have a working fire extinguisher, and to comply with any additional health and safety rules the town or village where the unit sits has adopted.

Booking services are barred from collecting a fee for a unit the county has not confirmed is registered, and the county can revoke a host's registration after three violations in two consecutive years.
