ADU Construction and Garage Conversions

Since California introduced legislation in 2020 making it easier to build accessory dwelling units, demand for ADU construction has grown considerably. Doza Build works as an ADU contractor helping homeowners take advantage of this opportunity, whether through a garage conversion or a newly built structure on their property.

For homeowners with an underused garage, a garage conversion to ADU can be a practical way to create an independent living space or generate rental income. Doza Build handles the construction side of these conversions and can also connect clients with experienced design and engineering partners who specialize in ADU planning and permitting submissions.

For those without a garage, Doza Build also constructs detached ADUs and attached ADUs from the ground up. This includes connecting plumbing to the main line and managing all aspects of the build. Their goal is to make the process straightforward for the homeowner, handling the construction complexity so clients don't have to.

An accessory dwelling unit is a self-contained secondary housing unit on a single-family residential lot. It includes its own kitchen, bathroom, and sleeping area. Homeowners typically build ADUs to generate rental income, house family members such as aging parents or adult children, or add long-term value to their property. Recent state-level legislation in California has made most single-family properties eligible to build at least one ADU, though local zoning rules, setbacks, and utility availability still vary by municipality.

The ADU Building Process

Doza Build's approach to ADU projects generally follows a structured process:

  1. Initial consultation and site assessment — evaluating the property, discussing the homeowner's goals, and reviewing local zoning requirements.
  2. Design and planning — working with architectural partners to develop plans that meet both the client's needs and local building codes.
  3. Permit acquisition — preparing and submitting the necessary documentation to local planning and building departments. If Doza Build's partner architect is involved, they manage this process directly.
  4. Construction — managing all aspects of the physical build, from foundation to finishes.
  5. Final inspection and handover — ensuring the completed unit meets code requirements before delivery.

The overall timeline for an ADU project can range from roughly 8 to 18 months depending on the scope. Design and planning typically takes 1 to 2 months, permitting can take anywhere from 3 to 8 months depending on the local jurisdiction, and construction itself generally runs 3 to 6 months. Costs vary based on size, design complexity, materials, site-specific factors, and permitting fees. Doza Build provides itemized estimates following an initial consultation and feasibility review.

For homeowners considering whether their property qualifies, Doza Build offers a free estimate and site evaluation to assess eligibility and discuss the most suitable ADU options for the specific property.

"When I decided to build an ADU on my property, I had no idea where to begin, permits, design, budgeting, everything was completely unfamiliar. Thats when I hired Doza Build Construction, and from day one, Ralph and Mike made the entire process smooth and stress free. They guided me step by step, helping me navigate city approvals and submit the necessary plans with confidence. They provided a clear and accurate estimate, and the final cost was very close to their original estimate any overage came from my own decisions, like upgrading to premium tile for the bathroom shower walls. I had contacted two other contractors who quoted similar prices, but it was Ralph and Mikes professionalism, transparency, and genuine friendliness during our first meeting and throughout the project that truly set them apart. I couldnt have asked for a better team to bring my vision to life. I added nearly 749sf to my property a 2 bedroom 2 bath home very spacious with 10 foot high ceilings to make it look bigger. If you need an ADU built the right way with less stress they can help you."

"We had an excellent experience working with Ralph from Doza Build Construction on our full house remodel. From the beginning, Ralph was professional, communicative, and incredibly knowledgeable. He kept us informed throughout the process, addressed any questions or changes promptly, and made sure every detail was done right. The quality of workmanship is outstanding, and our home feels completely transformed. A full remodel can be stressful, but Ralph and his team made it smooth and well-organized. We highly recommend Doza Build Construction to anyone looking for reliable, high-quality remodeling work."

"Having bought a home after 15 years, we had a vision to convert our newly purchased gem into a home. We contacted a different contractor, but he didnt really envision what we had in mind. We were then given the opportunity to contact Ralph, through a family member and sought a second opinion. Ralph and his team listened and delivered what we had envisioned for our now forever home. The level of professionalism, commitment, and communication were impeccable and we are grateful for all the hard work and effort that was given."
