Quick Answers About Goodyear, AZ ADUs
Market Context
Goodyear has a median home value of $415,000. Adding an ADU typically increases that by 21.0% — approximately $87,150 in added equity. A 1-bedroom ADU in Goodyear rents for approximately $1,408/month in the Maricopa County rental market , yielding a 6.8% cap rate on the investment. Occupancy averages 92.0% in this market.
Top Goodyear neighborhoods for ADU investment include Historic Goodyear, Palm Valley, Estrella Mountain, Canyon Trails, North Goodyear. Older mid‑century single‑family lots with larger yards make detached ADUs feasible and lower construction cost barriers. Large single‑family lots near I‑10 and amenities provide space for detached ADUs and strong owner/renter demand.

Permit applications are reviewed by the Development Services Department , with a plan check timeline of approximately 9.0 weeks. Permit fees in Goodyear range from $3,200 to $9,500 depending on project scope. Design review: Yes - in areas subject to adopted design guidelines (e.g., residential design review districts/PADs and master-planned communities)

Property Eligibility
Is My Goodyear, AZ Property Eligible for an ADU?
Goodyear homeowners benefit from California's state ADU law — one of the most permissive frameworks in the country since 2020. Here's what applies to your property before you start designing.
Single-Family Home
Permitted on single-family lots in Goodyear under California state law. No owner-occupancy requirement in Goodyear — you can rent both units as investment properties. Ministerial permit approval — no neighbor input or discretionary design review.
Multi-Family Property
Up to 2 detached ADUs plus JADUs (Junior ADUs) within the existing main structure are permitted under California state law. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
Approximately 33% of Goodyear homes are in an HOA. California law (AB 670) prohibits HOAs from banning ADUs outright, but they can impose reasonable architectural standards. Our drawings include HOA submission formatting.
Always verify eligibility with Development Services Department before designing.
