ADUs & Garage Conversions in Orange County
Add living space, rental income, or room for family — built to code and handled from permit to final inspection.
Whether you want a detached ADU in the backyard or a garage converted into a livable unit, Socal Home Renovation handles the whole process. We run full crews across Orange County and San Diego and manage design, permits, foundation, framing, and finish work from start to finish.
Why Build an ADU
An accessory dwelling unit is one of the highest-return projects you can add to a Southern California property.
Rental Income
A finished ADU can be rented out for steady monthly income, often covering a meaningful part of your mortgage in Orange County and San Diego markets.
Room for Family
Aging parents, adult kids, or guests get their own private, self-contained space on your property — close by, but independent.
Added Property Value
Permitted, livable square footage adds real long-term value to your home and expands what your property can do for you.
How We Build It
Ground-up ADU or garage conversion, the process runs in three phases.
Design & Permits
We plan the layout, prepare the drawings, and pull permits with the city. California ADU law has opened up what is allowed, and we handle the approvals so you don't have to navigate them.
Foundation & Framing
Footings, foundation, and framing for a new build — or converting the existing garage structure. Inspections are scheduled and handled by our team at each stage.
Move-In Ready
The unit comes together: kitchen, bathroom, flooring, lighting, and paint, all finished to the same standard as the main house. We complete the punch list and hand you a space that's ready to live in.
Final pricing depends on size, site conditions, and finishes. Garage conversions are quoted separately based on the existing structure. Estimates are free.

What Our Clients Say
We hired Socal Home Renovation to convert our detached garage into an ADU for my mom. With her health, having her close to us mattered, and we're so glad we did it. Ron was patient through the design, took us to showrooms to pick finishes, and kept us updated with photos in a group text the whole way. About 5 months start to finish, well organized. Highly recommend.
Maryam H. · Mission Viejo
We completed our ADU project in my parents' home in Costa Mesa and it was a great experience overall. Ron handled the project from planning, design and permit throughout the construction. Huge benefit to work directly with the owner and not a project manager or salesman. Two weeks after completion the unit has been rented.
Leo N. · Costa Mesa
Just finished a garage conversion in Lake Forest and couldn't be happier working with Ron, who handled everything from start to finish. Accuracy in each detail! Looking forward to do more work with him and his team soon.
