Home Additions in Orange County & San Diego
More room without moving — built to code and handled from permit to final inspection.
Whether you need a ground-floor room addition, a second story, or a primary suite, 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 Add On Instead of Moving
In Orange County and San Diego, buying the extra space usually costs more than building it.
Keep Your Location
Your schools, your commute, your neighbours. Adding on gets you the space you need without giving up the address you chose.
Space That Fits Your Family
A primary suite, a bigger kitchen, another bedroom or a second story — built around how your family actually lives.
Added Property Value
Permitted, livable square footage adds real long-term value to your home and counts toward its size on record.
How We Build It
Ground-floor addition or second story, the process runs in three phases.
Design & Permits
We plan the layout, prepare the drawings, and pull permits with the city. Setbacks, height limits and structural review all get handled, so you don't have to navigate them.
Foundation & Framing
Footings, foundation, and framing tied into the existing structure. Inspections are scheduled and handled by our team at each stage.
Finished and Integrated
Drywall, flooring, lighting and paint, matched to the rest of the house so the addition reads as part of the original home rather than an attachment. We complete the punch list and hand it over ready to use.
Final pricing depends on size, site conditions, and finishes. Second story additions 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
Ron and his team updated our kitchen — painting cabinets, tiled backsplash and new countertops — painted the entire house, replaced several windows and retiled our bathrooms. The quality of work was outstanding, and the price was excellent. Communication was seamless.
