Tiny homes in Scottsdale, Arizona — zoning rules, THOW parking, builder costs, and what you need to know before buying.
Last researched May 2026
Scottsdale is Arizona's luxury lifestyle capital — world-class golf resorts, Old Town's arts and dining scene, McDowell Sonoran Preserve hiking, and median home values near $785,000 that are among the highest in the state. Tiny home buyers here typically use ADUs as high-end guest suites, in-law units, or private retreats on existing properties rather than as primary residences. The market supports experienced custom builders but also carries strict HOA oversight in most subdivisions. Sunshine is plentiful and winters are mild; summer highs exceed 110°F and the urban heat island effect is pronounced.
Scottsdale is a high-end Phoenix-metro city that falls under the HB 2720 mandate. As of January 1, 2025, Scottsdale must allow at least one attached and one detached ADU by right on single-family lots. ADU size is capped at the smaller of 1,000 sq ft or 75% of the primary dwelling's gross floor area, setbacks cannot exceed 5 feet from rear and side property lines, and no additional parking can be required. Historically, Scottsdale permitted detached guest houses without full kitchens rather than ADUs; the City has been the most publicly resistant Arizona municipality to HB 2720, and as of late 2025 had approved only one ADU application with no building permit yet issued. The mayor has spoken out against the law over short-term rental concerns.
Foundation tiny homes are permitted where they meet the 2018 IRC and Scottsdale Zoning Ordinance — 200 sq ft minimum with 6'4" minimum ceiling height. Maricopa County has not confirmed adoption of IRC Appendix Q, so most small dwellings proceed under standard IRC. Scottsdale permit review typically runs ~10 weeks with fees around $1,200, higher than most Arizona cities.
THOWs are RVs under A.R.S. § 33-2102 and cannot serve as permanent dwellings on Scottsdale residential lots. Full-time THOW residency is limited to licensed RV parks; Scottsdale has very few in-city RV parks, so most residents use Phoenix or Mesa-area communities. HOA CC&Rs cover most of Scottsdale and commonly restrict accessory dwellings regardless of what state law permits — this is especially important in Scottsdale given dense master-planned developments. Verify current requirements with your local planning department before purchasing land or beginning construction.

HB 2720 requires Scottsdale to allow one attached and one detached ADU by right on single-family lots as of January 1, 2025. Size cap: smaller of 1,000 sq ft or 75% of primary dwelling gross floor area. Setbacks cannot exceed 5 feet from side and rear property lines, no additional parking required. Scottsdale has been the slowest major Arizona city to process applications under the new law, so expect longer informal timelines than in Phoenix or Tucson, and confirm current ordinance status with Scottsdale Planning & Development Services before design. Scottsdale's high-end market supports a specialized tiny-home/ADU builder pool; custom projects commonly run $175,000–$325,000+ all-in, reflecting Scottsdale permit fees ($1,200+), higher utility hookup costs, and premium finish expectations.
Communities, RV parks, and parking options in and near Scottsdale.
Scottsdale has very limited in-city RV park inventory and does not permit THOWs as dwellings on standard residential lots. Long-term THOW or park model placement typically requires traveling to Mesa, Apache Junction, Phoenix, or Cave Creek area parks. Expected pad rent in the Phoenix-metro resort tier runs $700–$1,200/mo in 55+ communities, higher than the Tucson or rural Arizona market. Units under 320 sq ft register as travel trailers through Arizona MVD; 320–400 sq ft units are park models requiring RVIA/ANSI A119.5 or NFPA 1192 certification. Register before transport.

Yes, as of January 1, 2025, Scottsdale must allow at least one attached and one detached ADU by right on single-family lots. However, Scottsdale has been the slowest major Arizona city to process applications — only one ADU had been approved as of late 2025. Confirm current ordinance language and application status with Scottsdale Planning & Development Services.
State law caps ADUs at the smaller of 1,000 sq ft or 75% of the primary home's gross floor area. Setbacks cannot exceed 5 feet from side and rear property lines, and Scottsdale cannot require additional parking.
Often no. HB 2720 does not override private HOA CC&Rs, and most of Scottsdale sits in HOA-governed master-planned communities or gated subdivisions with restrictions on detached accessory structures. Review CC&Rs carefully before purchasing or starting design — this is especially important in Scottsdale.
Not on a residential lot. THOWs are RVs under Arizona law and cannot be used as permanent dwellings in Scottsdale single-family zones. The city has very few in-city RV parks — most long-term THOW placement happens in Mesa, Cave Creek, or other Phoenix-metro areas.
Turnkey Scottsdale ADUs commonly run $175,000–$325,000+ all-in, reflecting higher permit fees (~$1,200), utility hookup costs, and premium finish expectations compared to other Phoenix-metro cities. Custom high-end projects can exceed this range significantly.
