Peoria distinguishes between tiny homes on permanent foundations and those on wheels. Foundation-based tiny homes may qualify as ADUs under Section 21-316, which was updated in late 2024 to comply with Arizona HB 2720. ADUs are permitted on any lot where single-family use is allowed. They must be self-contained living units with sleeping and sanitation facilities. A building permit is required, and the unit must meet International Residential Code standards. Tiny homes on wheels are classified as recreational vehicles under Peoria's zoning code and cannot serve as permanent residences. RVs may be stored on residential property subject to parking regulations but cannot be connected to utilities for habitation. Peoria's northwest Valley location includes many newer master-planned communities with HOA restrictions that may further limit tiny home and ADU options.
Using a tiny home on wheels as a permanent residence violates zoning. Building without permits results in code enforcement action.
