Casita Builders in Arizona: Exploring the Southwest’s Favorite Backyard Home

In Southern Arizona, casitas have long been a thoughtful way to add both function and charm to a property. Whether you’re hoping to create space for visiting family, generate rental income, or simply make your home more flexible, a well-designed casita can serve many meaningful purposes.

Let’s take a closer look at what makes casitas such a valued feature in the Southwest—and how choosing the right builder can help bring your vision to life.

What Is a Casita—and Why Are They So Popular in Tucson?

A casita (Spanish for “little house”) is a fully functional living space built on the same property as a main custom home. Also known as an accessory dwelling unit (ADU) or guest house, casitas provide a private area for guests, extended family, or even a rental tenant. In Tucson and across Southern Arizona, the tradition of the casita is tied to the region’s history of multigenerational living, hospitality, and smart use of land.

Today, with changing family needs and rising property values, homeowners are rediscovering the functionality and flexibility of these charming tiny homes.

  • “You and your team made it possible – all the way from help creating the plans, drafting the architectural drawings, and of course building our spaces. Your professional approach built confidence from the beginning. Everyone that worked on our project added to a great final product. Finishing the project for the same price that you quoted at the beginning was a pleasant surprise. Tieraona and I appreciated how you kept us informed, and completed work with the quality that you promised at the beginning of the process. You can count on us to recommend your company.”

  • “Aaron designed plans for my wife and me that combined a 3-room casita with attached 2-car garage. His comprehensive knowledge and attention to the smallest details were enormously helpful. From structural considerations to aesthetics, from siting to permitting, he made a complex process simple, providing multiple iterations until the vision we had for this space was realized. His focus on cost-savings as well as quality were greatly appreciated. Aaron was a pleasure to work with and we highly recommend him.”

  • “The construction process was smooth and Aaron’s team was in constant communication with us. They provided us with proper expectations and then met or exceeded them. This gave us a great sense of ease for we have remodeled before with a different contractor and it was constant anxiety. Aaron & Co finished the project about two weeks early than promised and kept the project within our provided budget, including the changes that we requested. The final product turned out beautifully and the service rendered was outstanding.”
