Detached living spaces — whether they’re to house a family member or serve as an extension of the home’s outdoor entertainment space — are playing a big role in Phoenix’s luxury market. In May, four of the top five Metro Phoenix home sales featured casitas or detached homes in their marketing materials.

That builds on a law that took effect last January, allowing homeowners to build accessory dwelling units on properties in cities with more than 75,000 people.
An ADU is a secondary home on the same lot as a primary residence. Detached ADUs, often referred to as “casitas” by Arizona agents and homeowners, typically require more extensive renovations, such as running power, plumbing and sanitation lines from the main house.
In the luxury market, these casitas are often an extension of the main residence with similar finishes and the same comforts — just in a smaller footprint.
As is the case with most months, Paradise Valley and Scottsdale were again home to Phoenix’s priciest transactions for May.
The top sales are based on Multiple Listing Service entries on Homes.com pulled on June 1. They do not include some off-market transactions.
