Full Breakdown
The Kootenai County Land Use and Development Code has no chapter specifically for 'tiny homes.' How a tiny home is regulated depends on its type. A tiny home on a trailer is a recreational vehicle or, under 8.4.403, a park model recreational vehicle, both subject to the RV rules of Article 3.4: RVs cannot be used as a dwelling except in narrow cases, the owner must keep a separate primary residence, and RVs must connect to an approved Panhandle Health District sewage system. A tiny home built on a permanent foundation is regulated as a single-family dwelling and must meet the building code and zone standards. A second permanent tiny home may qualify as an accessory living unit under 8.4.301.
Violations & Fines
Using an RV or park model as a full-time residence outside the code's exceptions is a violation; enforcement follows Article 8.6.
