What Is an ADU?

A Smart Addition to Any Property.

An ADU — Accessory Dwelling Unit — is a self-contained secondary residence built on the same lot as your primary home. In Arizona, they’re often called casitas, guest homes, or backyard cottages.

Perfect for hosting family, generating rental income, housing aging parents, or adding long-term value. With recent changes to Arizona law, permitting has never been simpler — and ProLux Homes handles the entire process for you.

Arizona ADU Law Update

Arizona Made It Easier to Build ADUs — Here’s What That Means for You

Recent Arizona legislation (SB 1117 and related bills) significantly streamlined the ADU permitting process. Most municipalities are now required to allow ADUs on single-family lots — fewer obstacles, relaxed setbacks, shorter timelines, and reduced fees. ProLux Homes stays current on all Arizona ADU regulations so you don’t have to. We handle permits, inspections, and compliance from start to finish.

ADU Frequently Asked Questions

In Arizona, “casita” and “ADU” are used interchangeably — both refer to a self-contained secondary dwelling on the same property. Also called guest homes. They all mean the same thing: a fully functional living space with its own entrance, kitchen, bathroom, and bedroom(s).

Most single-family properties in Arizona can accommodate an ADU thanks to recent state legislation. Feasibility depends on lot size, setbacks, and local codes. ProLux Homes offers a free site assessment to determine what’s possible on your property — no obligation.

ADU costs in Arizona typically range from $90,000 to $200,000 depending on size, configuration, and finishes. ProLux Homes provides a detailed, transparent estimate after your initial consultation — no vague ranges, no hidden fees.

From permit approval to keys in hand, ProLux Homes typically completes an ADU in approximately 120 days. Permitting takes 2–6 weeks depending on your municipality. We start permitting immediately after you sign.

Yes. Arizona law permits ADU rentals on most single-family properties. Long-term and short-term rentals (Airbnb) are generally allowed, though short-term rules vary by city. Phoenix-area ADUs typically rent for $1,500–$2,000/month.

An ADU typically increases your property’s assessed value, which can modestly increase taxes. However, rental income almost always far outweighs any tax increase. We recommend speaking with a local CPA for specifics.
