Bonner County, ID Fire Regulations: Smoke Detectors (2026)

The smoke detector requirement sits in § 11-102 B, the rehabilitation standard for pre-HUD mobile homes. It applies to mobile homes, as evidenced by proof of title, constructed before June 15, 1976, and it must be met before the Bonner County Planning Department issues the building location permit under § 11-102 A.

The detector, which can be a single station alarm device, goes on any wall in a hallway or space communicating with each bedroom area and the living area, on the living area side. When it is located in a hallway, the detector sits between the return air intake and the living area. Each detector is installed in accordance with its listing, with its top on a wall four inches to twelve inches below the ceiling. Power can come from a battery or from a permanent wiring connection to an electrical outlet box on a general electrical branch circuit, with no switch between the over current protection device protecting the branch circuit and the detector.

The rehabilitation list carries other fire and life-safety items alongside the detector. Compartments with a gas fired furnace or water heater are lined with five-sixteenths inch gypsum board unless the door opens to the exterior. Each sleeping room needs an exterior exit door or an egress window or other approved exit device with a minimum clear dimension of twenty two inches and a minimum clear opening of five square feet, with the bottom of the exit not more than thirty six inches above the floor.

Proof of compliance comes from an ICBO certified building inspector, gas utility provider, licensed electrical contractor or licensed plumbing contractor on a mobile home rehabilitation certificate form from the Planning Department, or from a certificate of compliance issued by the Administrator of the Division of Building Safety of the State of Idaho (§ 11-102 B.7).
