Arizona ADU Builder & General Contractor

Prime Builders AZ is a licensed Arizona general contractor (AZ ROC #354956) specializing in accessory dwelling units (ADUs), backyard casitas, guest houses, pool houses, and garage conversions.

Our casita models range from efficient 325 sq ft studios to spacious 800 sq ft two-bedroom homes, with all-inclusive pricing starting at $69,900 and monthly financing options from $492/month for qualified buyers. Whether you're building a rental ADU for passive income, a guest house for family, or a poolside lounge, we provide transparent pricing, realistic timelines, and a free on-site assessment to confirm what your lot allows before you commit.
Thanks to Arizona's ADU-friendly legislation (including HB 2720), homeowners in Phoenix, Mesa, Scottsdale, Gilbert, Chandler, Glendale, Tempe, Queen Creek, Peoria, Surprise, Goodyear, and Avondale can now add legal, permitted ADUs to most single-family lots. We handle the zoning research, setbacks, and permit paperwork so your project moves from design to move-in in as little as eight weeks of construction.
