Several Westchester villages cap unhosted short-term rentals at 90 to 120 nights per calendar year, mirroring suburban approaches used in Westport CT and parts of Long Island, while hosted stays usually face no annual limit.
Night-cap rules limit how many nights per calendar year a dwelling may be rented short-term when the owner is absent. Typical caps in Westchester villages range from 90 to 120 nights, tracked through the local building department or a contracted STR compliance vendor. Hosted stays, where the owner is present, generally do not count against the cap. Bookings beyond the cap must convert to long-term leases of 30+ days. Westchester County does not set a uniform cap. Hosts must self-report nightly bookings or face audit by the village clerk.
Exceeding the night cap triggers fines escalating from $250 to $1,500 per excess night and possible revocation of the STR permit.
