⚠️
Heads Up — Local Complexity in Paradise Valley

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.

Expert's Note — Charlotte Pemberton, Senior ADU Consultant
"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.

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.

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.

Construction costs in Paradise Valley typically range from $200–$400 per square foot depending on project complexity, finishes, and site conditions.
What is the maximum ADU size allowed in Paradise Valley? +
Paradise Valley permits ADUs up to 1,000 sq ft. The maximum height is 16 ft. Side setbacks are 20 ft and rear setbacks are 20 ft. Arizona's HB 2720 caps state-mandated ADUs at the lesser of 75% of the primary home's floor area or 1,000 sq ft (larger lots may allow more).
How long does the ADU permit process take in Paradise Valley? +
Arizona's HB 2720 sets no fixed statewide day-count for ADU review — plan check commonly runs 4–10 weeks depending on the jurisdiction.
Do I need owner-occupancy to build an ADU in Paradise Valley? +
No — Paradise Valley does not require owner-occupancy for ADUs. You can rent both the main house and the ADU as investment properties.
What's the rental income potential for an ADU in Paradise Valley? +
In Paradise Valley, a 1-bedroom ADU rents for approximately $1,494/month. Studios average $1,549 and 2-bedroom units bring $2,000. With an occupancy rate of 94%, annual gross rent on a 1BR ADU would be approximately $16,852.
How much does it cost to get ADU drawings in Paradise Valley? +

What drawings are required for an ADU permit in Paradise Valley? +
Paradise Valley's building department requires: a site plan, floor plans, elevations (all four sides), an electrical plan, and energy compliance documentation (AZ energy code). Our Standard package includes all of these. The Premium package adds structural plans with engineer stamp — required for detached ADUs in most Arizona cities. All drawings are AZ-code compliant and formatted for local submission.
Can I convert my garage to an ADU in Paradise Valley? +
Yes. Garage conversions are one of the most cost-effective ADU options in Paradise Valley. Conversion costs start around $115,000 — significantly less than new construction. The existing footprint counts toward ADU square footage limits. Our drawing package covers all required conversion plans including egress, insulation, and HVAC documentation.
What neighborhoods in Paradise Valley are best for ADU investment? +
Clearwater Hills, Paradise Canyon Foothills & Club Estates, Mummy Mountain Estates. Secluded hillside enclave with acre-plus lots and proximity to Camelback Mountain, supporting premium casita builds for high-end renters.
Is Paradise Valley ADU-friendly? +
Paradise Valley is governed by Arizona's HB 2720 and HB 2928 (2025), which allows ADUs on qualifying lots and limits how far local zoning can restrict them. Paradise Valley allows ADUs up to 1,000 sq ft. Arizona doesn't set a fixed statutory review-day count — confirm the current timeline with the Community Development Department.
How much will an ADU increase my property value in Paradise Valley? +
ADUs in Paradise Valley typically increase property values by 20%. On a $3,200,000 home, that's an estimated $640,000 in added value. Cap rates average 5.5% in Paradise Valley.
Can I use my Paradise Valley ADU as a short-term rental (Airbnb / VRBO)? +
Paradise Valley restricts short-term rentals (under 30 days) in ADUs. The unit can be rented long-term — a 12-month lease is the most straightforward path. Arizona's SB 1350/SB 1168 generally preempt outright local STR bans, so any restriction in Paradise Valley is more likely a registration, occupancy, or safety condition — confirm current local rules.
Does Paradise Valley's seismic zone affect ADU construction requirements? +
Paradise Valley falls within Seismic Design Category B. This means ADU foundations, anchor bolts, shear walls, and hold-downs must meet Paradise Valley's locally adopted building code — Arizona has no notable statewide seismic or wind-load mandate, and no single mandatory statewide energy or building code (cities adopt their own editions) — required for detached ADUs and strongly recommended for garage conversions where the existing structure may not meet current seismic standards.
Where do I submit ADU plans in Paradise Valley? +
Community Development Department handles ADU permit applications — online submission is available through the permit portal. Permit fees in Paradise Valley range from N/A to N/A depending on project scope and valuation. Our drawing sets are formatted specifically for Paradise Valley's submittal requirements to minimize plan check cycles.
