Families Who Already Enjoy Their Casita.
Building our casita with Sunflower was one of the best decisions we’ve made. We wanted a space for my parents, and the team understood exactly what we needed from day one. The whole process was clear, professional, and incredibly detail-oriented. Now my parents have their independence, and we have the peace of mind of keeping them close.

I started this project with the idea of renting my casita on Airbnb, and Sunflower guided me through everything — from design to permits. I was amazed by how well-optimized the space is and how quickly the investment pays off. You can tell they truly know what they’re doing and care about every detail
Olivia
I needed a private space to work from home, and Sunflower designed something that feels like a studio but with all the comfort of a full home. What impressed me most was the constant communication throughout the build and their commitment to deadlines.

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 to discuss size, materials, design, and financing options through our trusted partners. Once you decide, we guide you through every step—permits, construction, and completion—ensuring a smooth experience.
What are the requirements for adding a casita to my property in Arizona?
Under Arizona’s 2024 ADU law, most single-family lots can add a casita, but requirements vary by city. Generally, you need sufficient lot space (e.g., a backyard area meeting setback rules), compliance with local zoning (e.g., size limits up to 1,000 sq. ft. in many areas), and proper permits. Our on-site meeting assesses your property’s eligibility, and we handle permitting to ensure compliance.
Can I rent out my casita for additional income?
Yes! Arizona’s 2024 ADU law allows homeowners to rent out casitas for long-term or short-term use (e.g., Airbnb), depending on local regulations. A casita can generate significant rental income, often $1,000–$2,500 per month in Arizona, depending on location and size. We’ll discuss rental potential during our design meeting to maximize your investment.
What sizes and designs are available for my casita?
We offer customizable casitas, typically ranging from 400 to 1,000 square feet, to comply with Arizona’s ADU regulations. Designs include studio layouts, one-bedroom units, or custom configurations with features like kitchens and bathrooms. In our Phoenix office meeting, we’ll explore materials (e.g., wood, stucco) and styles (e.g., modern, traditional) to match your vision and property.
