Ada County may set STR occupancy limits, but only up to the same maximum that building code allows for any non-transient residence. Idaho Code 67-6539 bars stricter guest caps aimed only at short-term rentals.
Idaho Code 67-6539(3)(d) permits a county or city to require that maximum occupancy limits for STRs not exceed the non-transient residential limits in the International Building Codes as adopted by the Idaho building code board. In practice, occupancy is tied to the dwelling's building-code capacity, not a special STR headcount. Ada County cannot impose lower, STR-only occupancy caps. Occupancy typically scales with bedrooms, egress and square footage under the adopted residential/building codes; confirm your dwelling's rated capacity with Ada County Development Services.
Exceeding building-code occupancy can prompt code-enforcement action under the applicable building and safety codes; there is no STR-specific overcrowding penalty beyond those codes.
