Zoning
Boise permits STR (<30 days) in nearly all residential zones (R-1, R-2, R-3, R-O) and all commercial zones. Idaho Code §63-1801 (2017) is one of the strongest state-level STR preemption laws in the US — cities cannot prohibit STR by zoning class or use, only regulate for health/safety. Required: Boise STR permit + Idaho State Tax Commission STR registration + designated local contact + safety self-certification.
