ADU Rental Income in Arizona: Phoenix, Scottsdale & Tucson Rates (2026)
What Arizona homeowners actually earn renting an ADU — 2026 rent ranges for Phoenix, Scottsdale, and Tucson, what an Arizona ADU costs to build, cap rates, and the statewide HB 2720/2928 rules that make it possible.
How Much Does an ADU Rent for in Arizona?
Arizona is one of the more affordable major ADU markets to build in, and the state's two statewide laws — HB 2720 (2024) and HB 2928 (2025) — now guarantee ADUs by right on nearly every single-family lot in the state. That combination of lower build costs and strong legal footing makes Arizona ADUs some of the fastest-paying-off in the country.
Arizona ADU rental rates (2026):
| Market | Studio/1BR ADU | 2BR ADU |
|---|---|---|
| Phoenix | $1,200–$1,800/mo | $1,600–$2,400/mo |
| Scottsdale | $1,500–$2,200/mo | $2,000–$2,800/mo |
| Tucson | $950–$1,400/mo | $1,300–$1,900/mo |
These figures track with what we publish in the full ADU rental income guide and power the Arizona defaults in our ADU ROI Calculator.
What an ADU Costs to Build in Arizona
Arizona ADUs run $96,000–$180,000 statewide per our ADU cost report, among the most affordable of the major ADU markets thanks to lower labor and land costs than the coasts:
- Garage conversion: $70,000–$110,000 — reuses the existing structure and foundation, the fastest route to a rentable unit
- New detached ADU: $140,000–$220,000 — full new construction; finish level and lot access (especially on larger county parcels) push toward the top
- Junior ADU (interior conversion): $25,000–$45,000 — the cheapest way into the Arizona rental market, since there's no new structure at all

Arizona ADU Cap Rates and Break-Even
Example: Phoenix 1BR detached ADU ROI
- Project cost: $160,000 (detached, 650 sq ft)
- Monthly rent: $1,500
- Annual net income (after 10% expenses): $16,200
- Cap rate: 10.1% — break-even: roughly 9.9 years
Example: Phoenix JADU ROI
- Project cost: $35,000 (interior conversion, no new structure)
- Monthly rent: $1,000
- Annual net income (after 10% expenses): $10,800
- Cap rate: 30.9% — break-even: roughly 3.2 years
The same tradeoff shows up here as in every other market: a detached ADU brings in more total rent, but a JADU returns more per dollar invested because there's no foundation, framing, or roof to pay for.

Arizona ADU Zoning and Permitting
Arizona ADUs are governed by two statewide laws that override local bans:
- ADUs allowed by right: HB 2720 (2024) requires cities with 75,000+ residents — Phoenix, Scottsdale, Tucson, Tempe, and most others — to allow at least one attached and one detached ADU by right on single-family lots. HB 2928 (2025) extended nearly identical rules to counties, effective January 1, 2026.
- Setbacks capped at 5 ft: both laws cap rear and side setbacks at 5 feet in qualifying cities and counties, well below many pre-2024 local codes.
- No design-matching mandates: cities can't require the ADU to match the main house's exterior.
- Renting is protected: local governments can't restrict renting the ADU separately from the main house.
- Size limit: generally 1,000 sq ft or 75% of the primary dwelling, whichever is less, under the statewide baseline — some cities allow more.
- Permit timeline: 60–120 days statewide; Phoenix tends to run 60–90 days, while Scottsdale and Tucson often take 90–120 days.

How Phoenix Compares to Other Arizona Markets
| Market | 1BR Rent | 2BR Rent |
|---|---|---|
| Phoenix | $1,200–$1,800/mo | $1,600–$2,400/mo |
| Scottsdale | $1,500–$2,200/mo | $2,000–$2,800/mo |
Scottsdale commands the highest rents in the state, reflecting its higher household incomes and tighter rental supply, though build costs there run a bit higher too given lot sizes and finish expectations. Tucson is the value play — meaningfully lower rents, but also lower build costs, so cap rates land in a comparable range to Phoenix.

Frequently Asked Questions
How much can I earn renting an ADU in Arizona?
Most Arizona ADU owners see $950–$2,800/month depending on market and unit type, or roughly $11,400–$33,600/year in gross rental income. Net income after typical expenses (vacancy, maintenance, property management) runs about 85–90% of gross.
Is building an ADU in Arizona worth it?
For most owners, yes — Arizona's lower build costs relative to coastal states mean cap rates often land in the high single digits to low double digits for a detached unit, and JADU conversions can break even in as little as 3–4 years. HB 2720 and HB 2928 also mean you're entitled to build by right in nearly every city and county in the state, removing the discretionary-rezoning risk that slows projects elsewhere.
Do I need a permit to build an ADU in Arizona?
Yes. Permitting runs through your city or county planning department, and Arizona's statewide laws mean most lots are entitled to at least one ADU by right rather than through a discretionary rezoning. Ask about pre-approved plan sets where available to shorten the process.
What's the cheapest way to add rental income with an ADU in Arizona?
A Junior ADU (interior conversion), typically $25,000–$45,000 in Arizona — it uses existing space within the home, so there's no foundation, framing, or roof cost. See our Junior ADU guide for the full breakdown, including how it compares to a garage conversion or new detached unit.
