An ADU is one of the biggest opportunities in Gilbert right now, and the reason is the lots. Gilbert's master-planned communities were built out from the 1990s through the 2010s on generous suburban parcels, and many of those homes have the side yard or backyard room a true accessory dwelling unit needs. Unlike a casita, which is a guest structure, an ADU is a fully independent home — its own kitchen, bathroom, and private entrance — which is exactly what makes it work for aging parents, adult kids, or long-term rental. Arizona has expanded ADU allowances in recent years, but what your specific Gilbert lot can support still comes down to zoning, setbacks, and your community's rules. That's why every Gilbert ADU we build starts with a straight feasibility check before you commit a dollar, so you know what's actually buildable on your property.
An ADU is a complete, independent home on your property — its own kitchen, bathroom, and entrance. It's one of the smartest ways to add long-term value, house family, or generate rental income.
We manage the entire ADU process: feasibility, design, permits, utilities, and construction. Arizona's ADU rules have opened up major opportunities, and we help you make the most of your lot.
We proudly serve Gilbert neighborhoods including Val Vista Lakes, Power Ranch, Seville, Agritopia, Morrison Ranch, Layton Lakes. From your first call to the final walkthrough, you get transparent fixed pricing, full permit handling, and workmanship we stand behind.

ADUs (Accessory Dwelling Units) in Gilbert: What Local Homeowners Should Know
The first Gilbert-specific reality is feasibility, and it has two layers. The Town of Gilbert issues the building permits and sets the zoning and setback rules that govern whether a detached or attached ADU fits on your lot — and on top of that, most of Gilbert sits inside master-planned communities like Power Ranch, Seville, and Val Vista Lakes that require HOA architectural review for a new structure. A separate dwelling changes the footprint and is visible on the property, so it almost always triggers a submittal covering placement, rooflines, and exterior finishes. We run the feasibility check first, confirm what the Town and your HOA both allow, and prepare submittals designed to be approved the first time.
The second reality is what an ADU actually costs and returns in Gilbert. A full detached ADU with its own kitchen and bath commonly runs $150,000 to $300,000 or more depending on size and finishes, while a garage or attached conversion lands lower because the structure already exists. The most common Gilbert configuration is a detached one-bedroom unit tucked into a larger backyard, matched to the main home's stucco and roofline so it reads as original. Whether you can rent it, and on what terms, depends on your zoning and HOA — so we frame rental income as a real possibility to verify during feasibility, never a guarantee.
Gilbert Homes We Work On
Gilbert's housing stock skews newer than most of the East Valley. The bulk of the city was built out from the 1990s through the 2010s in large master-planned communities, which means many homes share popular builder floor plans — open-ish kitchens, big primary suites, and three-car garages on generous suburban lots. That consistency is actually an advantage for remodeling: we've worked on these floor plans many times and know exactly how to open a wall, extend a kitchen, or convert a garage in them.
ADUs (Accessory Dwelling Units) Costs in Gilbert
Remodeling costs in Gilbert track with the broader East Valley. As planning ranges, a mid-range kitchen remodel typically runs $30,000–$60,000, a full bathroom remodel $18,000–$35,000, and a walk-in shower conversion $8,000–$20,000. Room additions generally start in the tens of thousands and rise with square footage, while a detached casita or ADU commonly runs $150,000–$300,000+ depending on size and finishes.

Project Spotlight: A detached ADU on a Power Ranch lot
A Power Ranch family wanted independent space for a parent who values privacy but wanted to stay close. Their larger lot had room in the backyard for a true detached ADU — a one-bedroom unit with a full kitchen, a full bath, and its own private entrance, not just a guest casita. We confirmed setbacks with the Town of Gilbert, prepared the community's architectural submittal up front so HOA approval never stalled the build, and matched the main home's stucco, roofline, and paint so the unit looks original. Independent, code-compliant, and built to serve the family for decades.
Permits & HOAs for ADUs (Accessory Dwelling Units) in Gilbert
Gilbert is a city of master-planned communities, which means many projects also need HOA architectural review on top of the town permit — especially anything visible from the street like additions, casitas, exterior color changes, or new windows. Communities such as Power Ranch, Seville, and Val Vista Lakes each have their own guidelines, and we're experienced at preparing submittals that get approved the first time so your timeline doesn't slip.
