ADU Company in Santa Ana, CA
Kitchen remodeling in Santa Ana means working with homes built between the 1920s and 1950s, where original layouts were designed for a different era of cooking and family life. We opened our Santa Ana service area in 2017 because homeowners here kept asking the same question: how do you modernize a Spanish Revival or Craftsman kitchen without erasing the character that makes these houses worth owning? The answer is a remodel that respects the original bones while replacing outdated plumbing, wiring, and cabinetry. Call (855) 341-3461 for a free estimate on your Santa Ana kitchen.
Why Santa Ana Homes Are Different
Santa Ana is one of Orange County’s densest and most renter-heavy cities, and its older single-family lots near downtown in 92701, 92703, and 92704 are dominated by large rear yards and pre-1960s bungalows. That pattern shapes every kitchen remodel we do here. The housing stock tilts heavily toward 1920s through 1950s single-story stucco bungalows, Craftsman cottages, and Spanish Revival homes on narrow lots, many with detached garages fronting alleys. Inside these homes, kitchens were typically built small, closed off from living space, and wired for appliances that drew a fraction of what a modern range, hood, and refrigerator demand.
The local climate matters too. Warm, dry, semi-arid Santa Ana weather, including the hot offshore winds that give the city its name, means kitchens here need ventilation that actually moves hot air out during October heat spikes. We also see dust intrusion on rear-facing kitchens during wind events, so we pay attention to sealing and filtration details that wouldn’t come up in a coastal city. When we open walls in Santa Ana kitchens, we routinely find knob-and-tube wiring, galvanized supply lines, and undocumented prior work. A good remodel here is as much about correcting what’s behind the drywall as it is about choosing cabinets and countertops.
Our Main Santa Ana Services
Two services account for most of the calls we field from Santa Ana homeowners, and each has its own dedicated page with full pricing and process detail.
ADU Builders in Santa Ana
Santa Ana’s alley-facing detached garages in neighborhoods like Floral Park, French Park, and Lacy are the sweet spot for ADU conversions, but many were built before modern electrical codes and have been used as unpermitted living space or workshops. Bringing an old backyard garage up to code before it can legally become an ADU is a big part of the job here. We work across seven prefab platforms plus site-built construction, so the recommendation fits your lot, budget, and timeline rather than any single product line. ADU Builders in Santa Ana covers garage conversions, detached rear units, and the permit path in 92701, 92703, and 92704.
Bathroom Remodeling in Santa Ana
Bathrooms in Santa Ana’s pre-1960s homes tend to be compact, with original cast-iron plumbing and floor joists that have settled over eighty-plus years. We handle the full scope, from waterproofing and shower pan replacement to layout changes that make a small bath function like a larger one. Because Santa Ana sees wind-driven dust and dry heat, we recommend ventilation upgrades that keep moisture and particulates from building up in a windowless interior bath. Bathroom Remodeling in Santa Ana has the full breakdown of what these jobs involve and what they cost.

Kitchen Remodeling in Santa Ana
Kitchen remodeling in Santa Ana usually means taking a small, closed-off room in a 1920s to 1950s bungalow or Spanish Revival and making it work for how people actually cook now. The homes we work on in 92701, 92703, and 92704 were built when a kitchen was a service space, not the center of the house. We open walls, correct outdated wiring and plumbing, and rebuild kitchens that handle modern appliance loads without losing the character of the original architecture. Our Kitchen Remodeling process starts with a free estimate and a written line-item quote, so you know exactly what you’re paying for before demolition begins.
Cabinet and Layout Upgrades
Signs you need it
Your cabinets are original to the house, the hinges are failing, and the layout forces you to walk around an island that was never supposed to be there.
What it costs in Santa Ana
Cabinet refacing in Santa Ana typically runs $7,000 to $16,000, while custom cabinetry installations range from $150 to $300 per linear foot depending on material and finish.
How we do it
We measure the existing footprint, map where plumbing and electrical will move, present a fixed line-item quote, then handle demolition, framing, cabinet installation, and trim to a finished kitchen.
Countertop and Backsplash Installation
Signs you need it
Your countertops are chipped, stained, or made of a material that scorches and scratches, and the backsplash is original tile that no longer seals.
What it costs in Santa Ana
Countertop installation in Santa Ana generally falls between $50 and $150 per square foot for materials like quartz or granite, with full slab projects ranging from $2,000 to $5,000.
How we do it
We template the existing counters, remove old material down to the cabinet substrate, install the new surface with proper overhang and sink cutout, then set the backsplash and seal every seam.
Full Kitchen Electrical and Plumbing Correction
Signs you need it
Your breakers trip when you run the toaster and microwave together, or the supply lines under the sink are galvanized and corroding.
What it costs in Santa Ana
Electrical rewiring for a Santa Ana kitchen typically runs $3,000 to $8,000, and plumbing corrections range from $1,500 to $4,500 depending on access and the age of the original rough-in.
How we do it
We open the affected walls, run new dedicated circuits for appliances, replace supply and drain lines with code-compliant materials, and close, patch, and texture before finish work begins.

Will a kitchen remodel in Santa Ana require new electrical service?
It depends on the age of the home and what the existing panel supports. Many 1920s through 1950s Santa Ana homes have 100-amp panels that cannot handle a modern kitchen’s load, and we’ll tell you during the estimate if you need an upgrade before the remodel begins.
How long does a Santa Ana kitchen remodel take?
Most full kitchen remodels in Santa Ana run four to eight weeks from demolition to final walkthrough, depending on whether we’re moving plumbing, correcting wiring, or dealing with undocumented prior work. Call (855) 341-3461 for a timeline specific to your home.
