Quick Answers About Paradise Valley, AZ ADUs
Market Context
Paradise Valley has a median home value of $3,200,000. Adding an ADU typically increases that by 20% — approximately $640,000 in added equity. A 1-bedroom ADU in Paradise Valley rents for approximately $1,494/month in the Maricopa County rental market , yielding a 5.5% cap rate on the investment. Occupancy averages 94% in this market.
Top Paradise Valley neighborhoods for ADU investment include Clearwater Hills, Paradise Canyon Foothills & Club Estates, Mummy Mountain Estates, Camelback Country Estates, Jokake Camelback Properties. Secluded hillside enclave with acre-plus lots and proximity to Camelback Mountain, supporting premium casita builds for high-end renters. Phoenix Magazine's top-ranked Valley neighborhood features large estate lots near Camelback, ideal for detached ADUs serving resort/downtown professionals.
Permit Process
Permit applications are reviewed by the Community Development Department . Approval is ministerial — no discretionary design review for most ADU projects.
Paradise Valley's Hillside Building zones cover a huge share of the town, and if your lot sits on one, the Community Development Department will require a separate Hillside Development Permit before your ADU plans even get looked at — this means a site visit, slope analysis, and often a visibility study to prove the structure can't be seen from neighboring ridgelines or Camelback and Mummy Mountain. Because the town caps building height and disturbance area based on natural grade rather than a flat lot line, many homeowners have to hire a surveyor to establish exact slope percentages before an architect can even finalize the ADU footprint. On top of that, since STRs aren't allowed here, plan on the town asking for a signed affidavit confirming the ADU won't be rented separately from the main house — skipping this is a common reason applications get bounced back.
"In my experience, when the timeline and cost-per-sqft fields are blank like this, it usually means the platform never had reliable Paradise Valley-specific data to begin with rather than the town being unusually fast or cheap — I'd call the Community Development Department directly and get two or three local contractor quotes before assuming anything about your budget or schedule. What the data also doesn't capture is that even in the roughly 1-in-10 homes here without an HOA, Paradise Valley's own hillside and lot-coverage standards can be just as restrictive as a private HOA's design review."
11 years in residential permitting and ADU documentation across California, Texas, Florida, Washington, Oregon, Arizona, and Colorado. This guide was researched and verified against Paradise Valley's building department records and current 2026 Arizona's HB 2720 ADU law.
Property Eligibility
Is My Paradise Valley, AZ Property Eligible for an ADU?
Paradise Valley homeowners are governed by Arizona's HB 2720 and HB 2928 (2025). Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Paradise Valley under Arizona's HB 2720 and HB 2928 (2025). No owner-occupancy requirement in Paradise Valley — you can rent both units as investment properties. Arizona doesn't set a fixed statutory review-day count — confirm the current timeline with the Community Development Department.
Multi-Family Property
Additional ADUs on multi-family and duplex lots may qualify under Arizona's HB 2720 and HB 2928 (2025) — the exact number and type allowed depends on Paradise Valley's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 10% of Paradise Valley homes are in an HOA. Unlike California, Arizona law generally preserves HOA covenants that restrict ADUs — your HOA can still enforce a ban or design conditions through its CC&Rs. Our drawings include HOA submission formatting.
Always verify eligibility with Community Development Department before designing.

* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate.

Local Zoning Rules
2026 Paradise Valley ADU Rules
Paradise Valley's 2026 ADU ordinance caps new units at 1,000 sq ft and 16 ft of height — in the typical range most ADU floor plans are designed around. Setbacks run wide — 20 ft side / 20 ft rear — which pushes the buildable envelope toward the center of the lot. Paradise Valley doesn't trigger the extra engineer-stamp requirement we see in higher seismic-risk or hurricane-code cities — a standard code-compliant ADU under the size cap can typically be designed and submitted without an architect or engineer stamp, though any load-bearing change to the existing house still needs one.
Permit fees vary by project valuation — in line with what most homeowners budget for permitting through Community Development Department. Submit directly to the department online — link below.
| Regulation | Paradise Valley Allowance |
|---|---|
| Max ADU Size | 1,000 sq ft |
| Max Height | 16 ft |

| Owner Occupancy | Not required |
