ADU Company in Santa Ana, CA
Kitchen remodeling in Santa Ana usually means working inside a 1910s – 1950s stucco bungalow or a mid-century tract house where the original layout was built for a different era of cooking. We’re Classic ADU Builders, and we handle the full spectrum of accessory dwelling unit construction across Santa Ana, from Tuff Shed conversions off rear alleys to architect-designed modular units from Plant Prefab and Abodu. The same crew that builds your ADU shell can finish the kitchen inside it, which is why Santa Ana homeowners call us for both. Reach us at (877) 265-5587 for a free estimate.
Why Santa Ana Homes Are Different
Santa Ana’s housing stock is older and denser than most of Orange County. The core neighborhoods in 92701, 92702, and 92703 are built on a pre-war streetcar-era lot pattern: long, narrow parcels where houses front the street and garages sit at the rear lot line off paved alleys. Thousands of these lots are legally nonconforming by today’s zoning standards, which means a detached ADU often needs to replace or convert that rear garage rather than break new ground. The existing garage is frequently sitting on an old asphalt or dirt pad with no proper footing, so a conversion almost always means new foundation work first.
Climate matters too. Santa Ana sits inland behind the coastal hills, so summers run hotter and sunnier than beach-adjacent cities, and the dry offshore Santa Ana winds push real wind loads onto any new roofline. Mild winters mean ADUs don’t need heavy insulation, but they do need shade, cross-ventilation, and exterior materials that hold up to intense UV and dry heat. James Hardie fiber cement siding is our standard for that reason here.
Our Main Santa Ana Services
Santa Ana homeowners call us most often about two things: building an ADU on a rear-alley lot, and remodeling the bathrooms inside older homes that were built before modern plumbing expectations. Here’s how each works in this city.
ADU Builders in Santa Ana
Most Santa Ana ADU projects start at the rear lot line. The older core is full of detached one- and two-car garages off alleys, and converting or replacing one is usually the fastest permitted path to a rental unit or multigenerational suite. We check existing framing, verify the slab condition, and raise ceiling heights where code requires it before framing begins. We’ve built with Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab, so the conversation starts with your lot’s constraints, not a sales pitch for one product. Read more on our ADU Builders in Santa Ana page.
Bathroom Remodeling in Santa Ana
Bathrooms in 1920s Craftsman cottages and 1950s stucco tract houses were built small, often with cast-iron plumbing that has outlived its useful life. A remodel here means working around existing floor joists, correcting sloped floors, and sometimes relocating fixtures within a footprint that was never designed for a modern vanity or a walk-in shower. Because we also build ADUs, we handle bathroom work inside the unit as part of the same contract, not as a handoff to a second contractor. See the full scope on our Bathroom Remodeling in Santa Ana page.

Kitchen Remodeling in Santa Ana
Kitchen remodeling in Santa Ana usually means opening up a galley kitchen inside a 1920s bungalow or a 1950s tract house that still has its original footprint, original plumbing, and maybe one wall you can’t move without a structural engineer. The goal is almost always the same: more counter space, better flow, and a layout that works for how people actually cook now, without losing the character of the house. We do full kitchen remodels as standalone projects and as the interior finish for ADUs we build, which is where our Kitchen Remodeling experience pays off most. Every Santa Ana kitchen job starts with checking the existing slab or raised foundation, the age of the drain lines, and whether the wall between kitchen and dining room is load-bearing.
Full Kitchen Gut and Rebuild
Signs you need it
Your cabinets are delaminating, the layout forces a one-person kitchen, and the electrical panel can’t support modern appliances.
What it costs in Santa Ana
A full gut and rebuild with mid-range finishes typically runs $45,000 to $75,000 in Santa Ana, with higher-end work starting around $90,000.
How we do it
We demo to studs, correct any floor slope, rough in new plumbing and electrical, install cabinetry and countertops, then finish with backsplash, flooring, and appliance hookups under one contract.
ADU Kitchen Build-Out
Signs you need it
You’re adding an ADU and want the kitchen fully finished before the unit is rented or occupied by family.
What it costs in Santa Ana
An ADU kitchen build-out typically runs $18,000 to $35,000 depending on appliance tier and whether the unit is a Tuff Shed conversion or a modular system like Plant Prefab or Abodu.
How we do it
We coordinate cabinet dimensions with the ADU shell, run dedicated circuits for the range and refrigerator, install compact appliances, and finish with surfaces that meet Santa Ana’s rental-inspection standards.
Cabinet Refacing and Countertop Replacement
Signs you need it
The cabinet boxes are solid but the doors are dated, and the countertops are chipped laminate or cracked tile.
What it costs in Santa Ana
Cabinet refacing with new countertops generally runs $12,000 to $22,000, depending on linear feet and material choice.
How we do it
We replace doors, drawer fronts, and hardware, then template and install new countertops, leaving your existing layout and plumbing in place.

Will my Santa Ana home need electrical upgrades for a new kitchen?
Most pre-1960 homes in Santa Ana have 100-amp panels, and a modern kitchen with an induction range or double ovens usually requires 200-amp service. We inspect the panel at the estimate and include the upgrade in the quote if needed. Call (877) 265-5587 to schedule a free estimate.

What Santa Ana Customers Say
"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."
— Beatriz Morales"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Eric Tran"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Steve Mercer
