Short-term rentals
No local short-term-rental law on record - which is not the same as permission. Fremont has not adopted a local short term rental permitting law, so no local permit requirement is confirmed for this parcel. Since no local rule is on the books, confirm with the building department before counting on renting short term.
Conditions the code attaches:
- Sullivan County room tax registration is the primary requirement for renting a home short term here.
- The building department can confirm current requirements at (845) 887-6605 before you advertise or book.
