Why Tucson
Tucson offers a compelling mix of affordability, sunshine, and outdoor access that makes it one of the Southwest's most accessible tiny home destinations. The Sonoran Desert setting delivers 286 sunny days a year, hiking in the Santa Catalinas and Saguaro National Park minutes from downtown, and a cost of living roughly 30% below Phoenix. The city's laid-back desert culture, University of Arizona presence, and mature network of park model communities make Tucson particularly attractive for retirees, remote workers, and buyers priced out of Phoenix. Summer heat and monsoon storms are the main climate trade-offs.
Zoning & Placement
Tucson is one of the most tiny-home-friendly major cities in Arizona. The City amended its Unified Development Code (UDC) on October 22, 2024, with new accessory dwelling unit (ADU) rules effective November 21, 2024, bringing Tucson into compliance with HB 2720 (A.R.S. § 9-461.18). Under the amended UDC, property owners can build up to two casitas per parcel on a single-family lot by right, with each ADU capped at the smaller of 1,000 sq ft or 75% of the primary dwelling's gross floor area. ADUs up to 650 sq ft are allowed regardless of primary dwelling size. Side and rear setbacks are 5 feet minimum, no additional parking is required, and no public hearing or variance is needed.
Foundation tiny homes are well-supported: Pima County (which surrounds and includes most of Tucson) has formally adopted 2018 IRC Appendix Q, making Tucson one of the few Arizona jurisdictions with a dedicated tiny-home building code path. Minimum floor area is 200 sq ft with a 6'4" minimum ceiling height. THOWs (tiny homes on wheels) are classified as RVs under Arizona law — they cannot be used as permanent dwellings on standard residential lots, but can be parked long-term at licensed RV parks and park model communities such as Rincon Country West, Far Horizons, and downtown's Sentinel Peak RV Park, all of which accept full-time residents.
Permit fees run approximately $800 with a 6–10 week review timeline. HB 2928 (2025) extends similar by-right rules to unincorporated Pima County land effective January 1, 2026. HOA CC&Rs are not overridden by state law — review deed restrictions before purchasing. Verify current requirements with your local planning department before purchasing land or beginning construction.
Verify current requirements with your local planning department.
What to verify locally
- • Confirm whether your tiny home will be treated as an ADU, a site-built dwelling, or a recreational vehicle.
- • Ask about utility hookup requirements, especially sewer, electrical service, and emergency-access setbacks.
- • Check whether long-term occupancy is allowed on the lot type you are considering.
- • Verify minimum square footage requirements for your zone classification.
ADU & Backyard Tiny Homes
Under Tucson's November 2024 UDC amendment, single-family lots may have up to two ADUs (casitas) — typically one attached and one detached — as a by-right permitted use. Each ADU is capped at the smaller of 1,000 sq ft or 75% of the primary dwelling's gross floor area, but ADUs up to 650 sq ft are permitted regardless of primary size. Minimum side and rear setbacks are 5 feet; no additional parking required; no public hearing; no owner-occupancy requirement unless the ADU is used as a short-term rental after September 14, 2024. Factory-built tiny homes on permanent foundations qualify as ADUs if they meet IRC and local building code. Pima County's adoption of IRC Appendix Q gives tiny-home builders a defined permit path. Tiny Homes of Tucson publishes quoted pricing of $95,000–$195,000 for completed casitas depending on size and finish.
Where to Park
Communities, RV parks, and parking options in and near Tucson.
THOWs are classified as recreational vehicles in Arizona (A.R.S. § 33-2102) and cannot serve as permanent dwellings on standard residential lots in Tucson. Long-term THOW placement is legal at licensed RV parks and park model communities. Tucson has a mature network of these: Rincon Country West (1,100 sites, 55+), Far Horizons Tucson (300+ sites, 55+), and Sentinel Peak RV Park downtown (60+ sites, all ages, full-time residents welcome). Expected monthly costs range $450–$800 including pad rent, depending on amenities and age restrictions. Units under 320 sq ft register as travel trailers with the Arizona MVD; units 320–400 sq ft are park models requiring RVIA/ANSI A119.5 or NFPA 1192 certification. Register with MVD before transporting. Some communities require proof of certification and may charge additional fees for full-time occupancy.

Common Questions
Can I legally build a casita in my Tucson backyard?
Yes. Under the November 2024 UDC amendment, single-family lots can have up to two casitas (ADUs) by right — typically one attached and one detached. Each is capped at the smaller of 1,000 sq ft or 75% of the primary home's gross floor area, with a 650 sq ft minimum allowance regardless of primary size. No public hearing, no variance, and no additional parking is required.
Can I live full-time in a tiny home on wheels in Tucson?
Not on a standard residential lot. THOWs are classified as RVs under Arizona law and cannot be used as permanent dwellings in single-family zones. However, you can live full-time in a THOW at licensed RV parks and park model communities — Rincon Country West, Far Horizons, and Sentinel Peak RV Park all accept long-term or full-time residents.
Does Pima County allow IRC Appendix Q tiny homes?
Yes. Pima County, which surrounds Tucson, has formally adopted 2018 IRC Appendix Q — the section of the residential code specifically designed for dwellings under 400 sq ft. This gives builders a clear permit path for foundation tiny homes without needing variances, with a 200 sq ft minimum and 6'4" ceiling height.
What does a Tucson casita cost to build?
Tiny Homes of Tucson publishes quoted pricing of $95,000–$195,000 for completed casitas depending on size and finish: studios run $95,000–$112,000, one-bedroom units $114,000–$159,000, and two-bedrooms $145,000–$195,000. Permit fees (~$800) and utility hookups are additional. Expect a 6–12 month timeline.
Do Tucson HOAs have to allow casitas?
No. HB 2720 and the Tucson UDC amendment govern what the city can regulate — they do not override private HOA CC&Rs. If your property is in an HOA, review the CC&Rs before applying for a permit. Many Tucson subdivisions still restrict accessory dwellings regardless of what state and city law permit.
