Tiny Homes in Arizona

Arizona’s 2024–2025 legislative cycle delivered the most significant tiny home policy shift in the state’s history. HB 2720 requires 16 cities to allow ADUs by right on single-family lots — no variance, no public hearing, no special permit. HB 2928 extends the same framework to unincorporated county land as of January 2026. For buyers, that means two high-confidence paths: a foundation ADU in a major metro, or in some counties, a park model or THOW placement on private land.

Where to Place a Tiny Home in Arizona

Phoenix metro is the easiest entry point for foundation ADUs. Phoenix published updated guidance reflecting HB 2720 and allows multiple ADU configurations on qualifying lots. The 200 sq ft minimum and 6’4” ceiling height are the primary size constraints. THOWs classified as RVs cannot occupy standard residential lots permanently — Desert’s Edge RV Park (Phoenix, 220+ sites) is the largest urban THOW placement option in the metro.

Tucson and Pima County offer the most mature tiny home permitting framework outside Phoenix. Pima County formally adopted 2018 IRC Appendix Q and publishes explicit guidance distinguishing between foundation tiny homes, de-wheeled chassis, and mobile chassis — each is treated differently by zone. Tucson’s November 2024 UDC amendment allows two casitas per parcel (up to 1,000 sq ft). Tiny Homes of Tucson quotes $95,000–$195,000 for completed casitas. Rincon Country West (1,100 sites) and Sentinel Peak (downtown, full-time residents welcome) are the primary THOW/park model communities.

Flagstaff and Coconino County define any home under 600 sq ft as a “tiny house” and have adopted 2018 IRC Appendix Q. Wildfire zone requirements add a community input layer to ADU approvals. Village Camp Flagstaff and Woody Mountain Campground are the main THOW options. LuxTiny in Lakeside (White Mountains, 45 spaces) is Arizona’s most prominently marketed dedicated tiny home community — lot leases start at $379/mo including water, sewer, and trash; homes start at $64,900 to purchase.

Rural Arizona offers the lowest cost but the most variable rules. Mohave County allows travel trailers as temporary residences during construction. Yavapai County is the most restrictive of the common rural destinations — lot rental for THOW occupancy is explicitly prohibited under county ordinance; only property owners may occupy. Raw land in Coconino and Mohave counties is available owner-financed from ~$200/mo over 5 years.

Key Regulations to Know

Arizona does not have a formal statutory definition of “tiny home” — the 2024 attempt (HB 2096) failed 27–31. In practice, your unit falls into one of four legal categories: site-built dwelling (IRC), accessory dwelling unit (ADU under HB 2720/2928), park model RV (A.R.S. § 33-2102, 320–400 sq ft, RVIA-certified), or travel trailer (under 320 sq ft, RV classification). Each category triggers different permit, zoning, and occupancy rules.

For ADUs in the 16 HB 2720 cities, municipalities may not require matching exterior design, setbacks greater than 5 feet from rear/side lines, additional parking, or owner-occupancy of the primary dwelling (unless the ADU is used as a short-term rental after September 14, 2024). HOA CC&Rs are explicitly not overridden — check before you build.

Permit timelines vary: Phoenix is 8–12 weeks ($1,000–$2,500); Pima County/Tucson is 6–10 weeks ($800); Flagstaff is 6 weeks ($700); Scottsdale runs 10 weeks ($1,200). Utility hookup costs add $9,000–$34,500+ depending on rural vs. urban placement.

For THOW registration, contact the Arizona MVD at azmvdnow.gov. Register before transporting or placing the unit; some counties require a separate placement permit once the unit is sited.
