Quick Answers About Kingman, AZ ADUs
Market Context
Kingman has a median home value of $225,000. Adding an ADU typically increases that by 21% — approximately $47,250 in added equity. A 1-bedroom ADU in Kingman rents for approximately $850/month in the Mohave County rental market , yielding a 6% cap rate on the investment. Occupancy averages 88% in this market.
Top Kingman neighborhoods for ADU investment include East Kingman (Hualapai Mountain Rd), Golden Valley, Hilltop / Country Club, Centennial Park / Canyon Shadows, Downtown Kingman. Close to established single-family areas with larger lot parcels, making detached ADUs feasible and attractive to renters. Larger lot sizes and single-family fabric provide lots suitable for detached ADUs and a market for rental units.
Permit Process
Permit applications are reviewed by the Development Services , with a plan check timeline of approximately 10 weeks. Permit fees in Kingman range from $1,151 to $2,008 depending on project scope. Design review: Yes - in historic districts and in Kingman Design Review Overlay (KDRO) areas only
Many older lots in Kingman still run on a private septic system rather than city sewer, so Mohave County Environmental Health has to sign off on your ADU's capacity before Development Services will even accept your building plans — that review alone can tack on several weeks if your septic system was sized decades ago for a smaller household. On top of that, Kingman's water pressure and well-share agreements in some outlying subdivisions mean you may need a licensed engineer to confirm the existing line can support a second dwelling, which isn't something most contractors flag until they're already framing.
"In my experience with Kingman projects, that $300/sqft figure and the 10-week timeline are really state-level ballpark estimates, not Kingman-specific numbers — I've seen actual costs swing 20-30% in either direction once site conditions and finish levels come into play, so get two or three local contractor quotes and a call to Development Services before you bank on those figures for financing purposes."
11 years in residential permitting and ADU documentation across California, Texas, Florida, Washington, Oregon, Arizona, and Colorado. This guide was researched and verified against Kingman's building department records and current 2026 Arizona's HB 2720 ADU law.
Property Eligibility
Is My Kingman, AZ Property Eligible for an ADU?
Kingman 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 Kingman under Arizona's HB 2720 and HB 2928 (2025). No owner-occupancy requirement in Kingman — you can rent both units as investment properties. Arizona doesn't set a fixed statutory review-day count — confirm the current timeline with the Development Services.
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 Kingman's local rules. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 33% of Kingman 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.
Historic Districts
Yes - in historic districts and in Kingman Design Review Overlay (KDRO) areas only
Always verify eligibility with Development Services before designing.

Kingman ADU Return Calculator — Built With 2026 Local Data
Pre-loaded with verified Kingman construction costs, median rental rates, and property value uplift data. Adjust the inputs to model your specific project.
Your Project
Projected Returns
* Estimates only. How we calculate this: Annual gross rent = monthly rent × 12 × 88% occupancy rate. Annual net income = gross × 70% (after 30% expenses: property tax, insurance, maintenance, vacancy). Value added = median home value × 21% uplift (regional ADU comparables). Total return = net income × years + value added. Break-even = total build cost ÷ annual net income. Consult a licensed financial advisor before investing.

Kingman ADU Market at a Glance
Local Zoning Rules
2026 Kingman ADU Rules
Kingman's 2026 ADU ordinance caps new units at 1,000 sq ft — in the typical range most ADU floor plans are designed around. Setbacks run 5 ft side and 5 ft rear, close to the regional baseline. Kingman 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 run $1,151–$2,008 — notably inexpensive compared to most cities we cover, and plan check takes about 10 weeks at Development Services. Submit directly to the department online — link below.
| Regulation | Kingman Allowance |
|---|---|
| Max ADU Size | 1,000 sq ft |
| Max Height | 16 ft (detached) |
| Side Setback | 5 ft |
| Rear Setback | 5 ft |
| Architect / Engineer Stamp | Not required under the size cap* |
| Owner Occupancy | Not required |
| Short-Term Rental | Permitted |
| Coastal Overlay | No |
| Design Review | Yes - in historic districts and in Kingman Design Review Overlay (KDRO) areas only |
| HOA Prevalence | 33% of properties |
| Permit Fees | $1,151–$2,008 |
*Load-bearing modifications to the existing house always need an engineer stamp regardless of ADU size. Data verified 2026-07-12T23:00:00.000Z. Always confirm with the Development Services before designing.

Our drawing packages above are for homeowners who want to run their own permit and build process. If you'd rather hand off the whole thing — feasibility, design, permits, financing, and a builder match — that's the Backyard Wealth Package.
We turn your backyard into a rental unit. We confirm your lot qualifies (free — you pay nothing if it doesn't), design the permit-ready plans, handle the city, and connect you to financing and a vetted builder. One flat fee — about what an architect charges just to start. Yours would rent around $850/mo.
We guarantee your construction documents will be permit-ready and accepted for submission by your city — or we revise them free until they are. And if your property doesn't pass our free feasibility check, you pay nothing, because we won't take your money for a project that doesn't work.
