Primary-Residence-Only Rule
Idaho Falls does not require a short-term rental to be the operator's primary residence. The city's STR FAQ allows STRs in all zones permitting residential use with no owner-occupancy or primary-residence condition. Idaho Code 67-6539 bars cities from rules that effectively prohibit STRs, and a primary-residence-only mandate would conflict with that, so non-owner-occupied investor STRs are permitted in Idaho Falls.
