Arizona Building Contractors
Description
Arizona Building Contractors, LLC is a locally owned ADU contractor serving homeowners throughout Tucson, Marana, and Oro Valley. Unlike large national builders or high-volume construction companies, they operate as a Tucson-based general contractor with direct familiarity with the local market, permitting offices, and zoning requirements across Southern Arizona.
Their work focuses on designing and building accessory dwelling units that help homeowners create additional living space, generate rental income, or support multigenerational living arrangements. As an experienced accessory dwelling unit builder, Arizona Building Contractors handles the entire process internally — from planning and permitting through final construction.
ADU and Casita Construction Services
Arizona Building Contractors builds several types of secondary dwelling units and home additions depending on the property layout, zoning constraints, and homeowner goals.
Detached ADUs and Backyard Casitas
Detached ADUs are standalone structures built separately from the main residence. These units are commonly used as:
- Rental properties
- Guesthouses
- Backyard cottages
- Housing for aging parents or adult children
- Private workspaces or studios
Their detached casita projects are designed to integrate naturally with the existing property while maintaining privacy and independence from the primary home.
Attached In-Law Suites
For lots where a detached structure may not be practical, Arizona Building Contractors also builds attached ADUs and in-law suites that share a wall with the primary home while functioning as independent living spaces.
Garage Conversions
Existing garages can often be converted into fully functional accessory dwelling units. Arizona Building Contractors evaluates whether a garage conversion makes sense structurally, financially, and from a zoning perspective before moving into design and permitting.
Full Home Additions
In addition to standalone ADUs, the company also handles larger residential additions that expand the livable footprint of the home while maintaining architectural consistency with the existing structure.
Local Experience in Tucson and Pima County
One of the company’s strengths is its familiarity with local building departments and zoning regulations throughout:
- Tucson
- Marana
- Oro Valley
- Pima County
ADU construction in Southern Arizona involves navigating setback requirements, lot coverage rules, utility coordination, and municipal permitting processes that vary between jurisdictions. Arizona Building Contractors uses its local experience to help homeowners avoid common delays and approval issues that can slow projects down.
Full-Service Project Management
Arizona Building Contractors manages all major phases of the project under one coordinated process. Their services typically include:
- Initial feasibility discussions
- Design coordination
- Permit applications
- Foundation and structural construction
- Electrical, plumbing, and HVAC coordination
- Interior and exterior finishing
- Final walkthrough and project completion
Clients work with a single team throughout the process, helping simplify communication and reduce the challenges that often come with coordinating multiple contractors independently.
A Practical Approach to ADU Construction
Most homeowners who contact Arizona Building Contractors are looking to accomplish one or more of the following:
- Add long-term property value
- Generate rental income
- Create flexible housing for family members
- Build a private guesthouse or casita
- Add functional living space without relocating
The company works with homeowners to determine which ADU type makes the most sense based on the lot, budget, and intended use before construction begins.
As a licensed and fully insured contractor, Arizona Building Contractors positions itself as a straightforward, locally grounded option for homeowners considering a granny flat, casita, garage conversion, or detached accessory dwelling unit in the Tucson area.
