Kootenai County has no ordinance banning rain barrels. Rainwater collection in Idaho is governed by state water law: Idaho allows collecting rainwater and diffused surface water, but it is subject to state water rights and cannot injure existing water-right holders.
The county sets no local rule prohibiting or permitting rain barrels, so the governing law is the state. Idaho treats all water, including rainwater, as subject to the state's prior-appropriation water-rights system administered by the Idaho Department of Water Resources under Title 42. In practice, capturing rooftop runoff on your own property for yard use is allowed, but larger-scale collection that would impound or divert water and affect downstream water-right holders can require a permit. There is no Kootenai County registration or cap on residential rain barrels. Confirm larger systems with IDWR.
No county penalty for a residential rain barrel. Diverting or impounding water that injures a senior water right is a state water-law matter enforced by the Idaho Department of Water Resources.
