What Is an Accessory Dwelling Unit? 

An ADU is a separate living space built on the same property as your main home. It can be designed as a detached casita, attached addition, garage conversion, guest suite, or private living space for family.

One Property. More Possibilities.

Create space for aging parents, adult children, guests, a home office, or potential rental income while adding long-term function and value to your property.

Straight answers to the questions Arizona homeowners ask before starting a casita project.

Frequently Asked Questions

How does the process of adding a casita with SunFlower work?+

Our process is simple and guided. It starts with a short phone call to answer your questions and gather initial details. Next, we schedule an on-site meeting at your home to assess your property and confirm building feasibility. Then, we meet — at our Phoenix office or remotely, wherever you are in Arizona — to discuss size, materials, design, and financing options with our financing team. Once you decide, we guide you through every step — permits, construction, and completion — ensuring a smooth experience.

Can I build a casita or ADU on my Arizona property?+

Many Arizona properties may be eligible for a casita or ADU, but what can be built depends on the individual property and local requirements. Zoning, lot configuration, setbacks, utilities, existing structures, HOA requirements where applicable, building codes, and local permitting rules can all affect a project. Sunflower Casitas can help homeowners evaluate their property and understand the next steps.

Can I rent out my casita?+

Where legally permitted, a casita may provide homeowners with an opportunity for additional rental income. Rental eligibility, demand, rates, and potential income vary by property, location, local regulations, and market conditions.

What sizes and designs are available for my casita?+

We offer customizable casitas in a range of layouts, including studio plans, one-bedroom units, and custom configurations with kitchens and bathrooms. Allowable size depends on your property and local requirements. In our design meeting, we'll explore materials (e.g., wood, stucco) and styles (e.g., modern, traditional) to match your vision and property.

Why should I choose SunFlower Casitas for my ADU project?+

What types of financing options are available for my casita?+

Availability depends on borrower qualification, lender approval, property eligibility, applicable terms and program availability. Our financing team reviews your situation, explains what lenders typically look at, and helps you understand the possible terms and payments.
