Mount Vernon, NY Short-Term Rentals: Extended Home Share (2026)

Section 267-98F distinguishes two kinds of short-term rental under Mount Vernon's Zoning Code. Renting the entire dwelling unit is capped at 180 days per calendar year, but where only a portion of the dwelling unit is rented, such as a spare bedroom, there is no limit on the number of days in any calendar year, provided that an owner or tenant is physically in residence at the dwelling during the periods the room is being rented. This home-share path lets a resident host guests indefinitely as long as they never vacate the unit while the rented room is occupied.

The unlimited-day provision does not relieve the operator of any other requirement in Article XV: a short-term rental permit is still required (Section 267-97A), the unit must remain the operator's occupied primary residence (Section 267-96B), and the standards of Section 267-98, including the smoke detector, carbon monoxide detector, occupancy and noise-control requirements, still apply to the rented room. Whether a rental qualifies for the no-limit home-share treatment or falls under the 180-day whole-unit cap turns on the presence-in-residence requirement, and the Building Department can request records showing the number of days rented and confirming occupancy from any short-term rental website statement or a certified letter from the owner or tenant (Section 267-98F(1)-(2)).
