Idaho HB166 Protects Your Right to Build

Idaho House Bill 166 prohibits any city or county from imposing an outright ban on accessory dwelling units. That means Filer must have a permit process for ADUs — and as of July 2023, your HOA cannot block you either (on owner-occupied properties). Learn more about Idaho ADU law →
