Tiny home rules in Sahuarita, AZ β covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds β determine where they are legal and how they get permitted.
Sahuarita allows site-built tiny homes as ADUs (200 sq ft min) on permanent foundations. Tiny homes on wheels are classified as RVs. HB 2674 supports ADU-friendly zoning.
Tiny homes in Sahuarita fall into two regulatory categories. Site-built tiny homes on a permanent foundation are treated as accessory dwelling units (ADUs) or guest houses under the Land Development Code and must meet International Residential Code standards, including minimum ceiling height (6 feet 8 inches for habitable rooms), egress windows, and kitchen/bathroom plumbing. Arizona HB 2674 (2022) directed municipalities to allow ADUs in residential zones, and Sahuarita has been updating its code accordingly. Minimum size for a habitable dwelling is typically 200 square feet under Arizona building code. Tiny homes on wheels (THOWs) are classified as recreational vehicles under Arizona law and may not be used as permanent residences on residential lots. They can be parked for temporary occupancy (typically up to 30 days) with a valid RV registration. Manufactured tiny homes must comply with HUD code (federal) and receive an Arizona installation permit through the Office of Manufactured Housing. All tiny homes used as permanent ADUs need sewer or septic connection, potable water, and electrical service. In the Sahuarita area, septic system regulations through Pima County Department of Environmental Quality apply to properties not connected to the Sahuarita municipal water system.
Occupying THOW as permanent dwelling: code enforcement notice, 100 to 500 dollar fine. Unpermitted ADU construction: stop-work order, 200 to 1,000 dollar penalty. Non-HUD manufactured home placement: removal order.
