Summary
Mount Vernon limits short-term rental of an entire dwelling unit to 180 days per calendar year under Section 267-98F of the Zoning Code, counting any night the property is occupied overnight as a rental day, with proof of compliance required on request.
Short-term rental of an entire dwelling unit is limited to 180 days in any one calendar year. Where only a portion of the dwelling unit is subject to the short-term rental, there shall be no limit on the number of days in any calendar year, provided that an owner or tenant is physically in residence at such dwelling during those periods that the portion of the unit is subject to short-term rental. A rental day shall be deemed to mean any day that the property is occupied for rental overnight.
Full Breakdown
Section 267-98F caps short-term rental of an entire dwelling unit, meaning no owner or tenant is in residence during the stay, at 180 days in any one calendar year. The code defines a rental day broadly as any day the property is occupied for rental overnight, so partial-day turnovers still count as a full day against the cap. To verify compliance, the property owner or tenant must, upon request, provide a statement on letterhead from any short-term rental website platform used to advertise the unit showing how many entire-unit rentals occurred that year (Section 267-98F(1)), plus a certified letter from the owner or tenant stating the total days rented through any platform or other means (Section 267-98F(2)).
The 180-day cap applies only to whole-unit rentals; Section 267-98F separately allows unlimited rental days for a portion of a unit if the owner or tenant remains in residence. The cap sits inside the broader permit system: a short-term rental permit under Section 267-97 is required before any entire-unit rental, the Building Department maintains a citywide registry of all short-term rental units updated every six months (Section 267-102), and the unit is subject to inspection by the Building Department and Fire Department at initial application and renewal (Section 267-100).
Violations & Fines
Exceeding the 180-day cap on an entire-unit short-term rental violates Section 267-98F and is enforced under Section 267-101 with the penalties of Section 267-56A: up to a $1,000 fine or 15 days' imprisonment per conviction, with each day beyond the cap counted as a separate violation, and can also support permit revocation under Section 267-97C.
