Phoenix, Arizona
Casita & ADU Builder in Phoenix, Arizona
Sunflower Casitas is a licensed Arizona contractor (ROC #367652) building backyard casitas, guest houses and accessory dwelling units for Phoenix homeowners. We handle the property review, the design, the permitting, financing guidance and the construction itself, so one team is responsible from the first walkthrough to the final one.
Building a Casita in Phoenix
Phoenix lots vary enormously. A 1950s central-corridor property, a 1990s subdivision home in Ahwatukee and a newer north Phoenix build each present different setbacks, utility runs and access constraints, even when the homeowner wants the same casita. That is why we start with the property rather than the plan.
Desert construction also has its own demands: heat, sun exposure, monsoon drainage and soil conditions all shape how a casita should be built to last. Our models are designed for Arizona conditions, and every project is permitted and inspected through the jurisdiction the property sits in.
What Phoenix Homeowners Build
Backyard Casitas
A separate, self-contained space behind the main house — the most common request we get from Phoenix homeowners.
Guest Houses
Room for visiting family, aging parents or adult children, with privacy on both sides of the yard.
Accessory Dwelling Units
A full ADU with its own kitchen, bath and entrance, built and permitted as a second living space on the property.
Home Offices and Studios
A quiet, finished building separate from the house, used for work, art, fitness or a studio space.
Custom Casitas
Start from one of our models and adjust the layout, sizing and finishes to suit your lot and how you live.
Rental-Ready Spaces
Built to the same standard as the main home, for owners who intend to rent the space where local rules allow it.

What Decides Whether Your Property Qualifies
Not every Phoenix property can support a casita, and we will tell you honestly if yours looks like a difficult fit. These are the factors we look at first:
- Zoning and how the parcel is classified within the City of Phoenix or your city
- Lot size, setbacks and how much buildable space is genuinely left
- Water, sewer or septic, gas and electrical service capacity
- Access for equipment through side yards, gates and alleys
- HOA architectural requirements where a community has them
- Permit submittals, plan review and inspections for your jurisdiction
Casita Models Phoenix Homeowners Consider
Our models run from a compact backyard studio to a two-bedroom guest home. Each can be adjusted to fit the lot, and every model page shows the floor plan, square footage and layout.
Financing Guidance for Phoenix Homeowners
Many homeowners assume a casita means writing one very large check. Through our financing team, qualified homeowners can explore options that may allow them to build without paying the entire project cost upfront. What you may qualify for depends on your financial profile, your property and lender requirements.
Financing options are subject to borrower qualification, lender approval, property eligibility, applicable terms, and program availability.

We build across the Valley and the rest of the state — Scottsdale, Mesa, Gilbert, Chandler, Tempe, Glendale, Peoria, Paradise Valley, Cave Creek, Queen Creek, Surprise, Goodyear, Buckeye, and on to Tucson, Casa Grande, Maricopa, Prescott and Flagstaff.
Phoenix Casita Questions
- Can I build a casita in my Phoenix backyard?
- Many Phoenix properties can support a casita, but it is decided lot by lot. Zoning, the size of the lot, required setbacks, existing structures, utility connections, equipment access and, where one exists, HOA rules all affect what can be built. We review your specific address before anything is designed.
- Do I need a permit to build a casita in Phoenix?
- Casita and ADU construction is permitted work. The City of Phoenix reviews plans and inspects the work, and surrounding cities run their own processes. We guide homeowners through the submittals and approvals for the jurisdiction the property sits in.
- What is the difference between a casita, a guest house and an ADU?
- In everyday Arizona use they often describe the same thing: a smaller separate living space on the same property as the main home. What matters for permitting is how the structure is built and how it will be used, not which word you use.
- How much does a casita cost in Phoenix?
- There is no single price. Cost depends on size and layout, site conditions, how far utilities have to run, foundation and engineering requirements, the finishes you choose and local permit requirements. We give you a number after reviewing your property and plan rather than before.
- Do you serve cities around Phoenix?
- Yes. We work with homeowners across the Valley — including Scottsdale, Mesa, Gilbert, Chandler, Tempe, Glendale, Peoria, Paradise Valley, Cave Creek, Queen Creek, Surprise, Goodyear and Buckeye — and throughout the rest of Arizona.
- Do I have to pay for the whole casita upfront?
- Not necessarily. Qualified homeowners may be able to explore financing instead of paying the entire project cost in cash. Financing options are subject to borrower qualification, lender approval, property eligibility, applicable terms and program availability.
