Joliet's municipal code does not contain specific provisions for tiny homes. Tiny homes built on permanent foundations are treated as standard dwelling units and must comply with all International Residential Code requirements as adopted under Section 8-175, including minimum habitable room sizes, ceiling heights, egress requirements, and utility connections. Tiny homes on wheels (THOWs) are classified as recreational vehicles under the zoning ordinance and subject to the same parking and storage restrictions as RVs under Section 19-150 and Section 47-5.3, meaning they cannot be parked on city streets and must be stored on a proper driveway. THOWs cannot be used as a permanent residence on residential property without meeting all building code requirements for habitable space. Illinois HB 2373 (2024) addressing ADUs may provide additional flexibility for small accessory dwellings.
Unpermitted construction subject to fines up to $750. THOWs used as permanent residences without compliance may be ordered removed.
