Licensed & insured · 15+ years local · Free estimates — just call
An ADU — a complete, independent living unit with its own kitchen, bath, and entrance — is one of the smartest ways to add long-term value, house family, or generate rental income, and Florence's lot sizes make it achievable. The larger and semi-rural parcels around Magic Ranch and Arizona Farms often have the room a full ADU needs, while newer Merrill Ranch properties and even historic downtown lots can sometimes accommodate one. As a licensed and insured general contractor, we manage the entire Florence ADU process: feasibility, design, permits, utilities, and construction. The key questions here are always lot-specific — zoning, setbacks, and whether the property is on septic — and we answer them up front so you know what your Florence property can actually support before you spend a dollar on design.

ADUs (Accessory Dwelling Units) in Florence: What Local Homeowners Should Know
The defining Florence ADU consideration is septic. Many of the town's larger and rural lots are served by septic systems rather than municipal sewer, and because a true ADU is a fully independent dwelling with its own kitchen and bath, it adds meaningful load. That often means evaluating whether the existing septic system can handle the additional bedrooms and fixtures or needs expansion — a real cost and feasibility factor we assess before anything else. We also look at utility runs, separate metering options, grading, and site access on larger parcels. Getting these rural realities right at the feasibility stage is what separates a smooth Florence ADU project from an expensive surprise.
Permitting and lot rules complete the picture. An ADU in Florence runs through the Town of Florence for permits and inspections, with Pinal County considerations on some rural parcels, and zoning and setbacks govern whether a detached or attached ADU is allowed and how large it can be. We handle all of it, including a garage-to-ADU conversion where that is the better fit for the lot. On the design side, we match the ADU to the property — clean and modern in Merrill Ranch, character-sensitive near historic downtown, practical and durable on a rural lot — and build it with separate-entrance, rental-ready, or multi-generational configurations depending on your goals. Costs in Florence generally sit at or below the East Valley average, which helps the numbers work.
ADUs (Accessory Dwelling Units) Costs in Florence
Remodeling costs in Florence generally sit at or a little below the broader East Valley average, which is part of the town's appeal. 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, finishes, and site conditions.

Project Spotlight: A rental-ready ADU near Arizona Farms
On a larger lot out toward Arizona Farms, the owners wanted a full ADU for rental income. Because the property was on septic, our first step was confirming the system could support an independent unit — it needed an upgrade, which we built into the plan honestly rather than discovering it later. We designed a detached ADU with a full kitchen, bath, private entrance, and its own parking, ran separate utilities, and matched the exterior to the main home. Fully permitted through the Town of Florence and built to last, it is now a comfortable, independent unit generating steady income on land that was sitting unused.
Permits & HOAs for ADUs (Accessory Dwelling Units) in Florence
Florence's larger and rural lots bring a few added considerations. Properties outside the reach of municipal sewer often rely on septic systems, so an addition, casita, or ADU that adds bathrooms or bedrooms may involve septic capacity, site work, and additional review — sometimes at the Pinal County level as well as the Town of Florence. We assess your lot early, factor any septic and site-work realities into the scope, and fold it all into a single fixed-price quote so a larger rural project does not come with surprises.

Florence Neighborhoods We Serve
We serve homeowners across all of Florence, from the historic, character-rich streets of Downtown Florence to the newer Del Webb homes of Anthem at Merrill Ranch, the established neighborhood of Magic Ranch, and the larger semi-rural lots out toward Arizona Farms. Because Florence spans everything from century-old adobes to brand-new master-planned homes and rural acreage, we adjust our approach, finishes, and site planning to fit each property — and we handle permits through the Town of Florence and Pinal County across ZIP code 85132, so wherever you are in town, we already understand the local requirements.
Why Florence Homeowners Choose Gilbert GC
Florence's split personality — historic downtown on one side, a fast-growing Del Webb community and rural lots on the other — is exactly why it pays to hire a general contractor comfortable across all of it. A crew that only knows new builds can be out of its depth in a century-old adobe, and a crew that only does quick cosmetic work can miss what a larger rural project truly requires. We work across the full range of Florence homes and know how to get the best result from each.
