Idaho Falls, ID Short-Term Rentals: Occupancy Limits (2026)

The City of Idaho Falls does not publish a per-guest maximum occupancy specifically for short-term rentals. The one explicit operational limit in the city's Short-Term Rentals FAQ is on simultaneous bookings rather than headcount: "A short term rental cannot involve more than one guest party at a time." In practice this means a host may not rent separate rooms of the same dwelling to multiple unrelated parties at once, treating the home like a boutique hotel; the entire STR is rented to a single guest party for the stay. Beyond that rule, occupancy is governed by the generally applicable standards that apply to any residence: the city's zoning ordinance, building code, and housing/property-maintenance code, plus the underlying dwelling's design. Idaho Code 67-6539 reinforces this by directing that a short-term rental "shall be classified as a residential land use for zoning purposes subject to all zoning requirements applicable thereto," so the same density and dwelling-unit rules that apply to a normal household apply to the STR. The FAQ also restricts where an STR may occur in a way that bears on occupancy: an STR may not be located in an accessory structure not specifically designed for human habitation, and may not operate from a recreational vehicle or travel trailer except in an approved travel trailer court. Operators should confirm the safe occupancy of their specific dwelling under the applicable building and fire codes, which is the standard Idaho cities use for sleeping-room capacity.
