ADU Company in Orange, CA

Kitchen remodeling in Orange often means working inside homes built before 1960, where a gut renovation uncovers cast-iron drain lines, cloth-covered wiring, and framing that no longer matches any standard stud spacing. That’s our starting point on most Orange projects, and it’s why we price jobs differently here than we do in newer parts of the county. Whether you’re adding an ADU behind a Craftsman bungalow in Old Towne or remodeling a kitchen in a 1950s tract home east of the Plaza, you’re dealing with a house that predates modern building codes. Call us at (833) 589-8273 when you want a straight read on what your walls and foundation will actually require.

Why Orange Homes Are Different

Orange has one of the largest concentrations of pre-1950 housing in central Orange County, and it changes how we approach every project. A kitchen in a 1920s Craftsman near the Plaza often sits on a raised foundation with the original subfloor, which means leveling becomes part of the cabinet installation conversation. A detached ADU behind a 1950s ranch in the eastern neighborhoods typically needs a new electrical panel and a service upgrade before the first wall goes up, because the original 60-amp or 100-amp panel was never sized for a second dwelling with its own kitchen and laundry.

The climate also shapes our material choices in Orange. Summers run hot and dry inland, and the Santa Ana wind season raises real fire-ember concerns for detached structures. We recommend Class A fire-rated roofing on every ADU we build here, not as an upsell but as a basic precaution for a city that gets gust-driven ember showers every fall. On the interior side, we specify cooling systems that can handle a run of 90-plus-degree days without turning a 400-square-foot unit into an oven by 3 p.m.

Old Towne adds another layer. Mature citrus and avocado trees shade lots all through the historic district, and their root zones often cross the exact trench line where ADU utilities need to run. We’ve routed sewer and electrical lines around heritage trees more times than we can count, and we know when the city’s arborist review will require root barriers. None of this is typical Orange County tract work. It’s specific to Orange, and you want a crew that’s seen it before.

Our Main Orange Services

Orange homeowners call us most often for two projects: building an ADU that clears the city’s historic-review and setback requirements, and remodeling a bathroom in a house old enough that the pipes are original. Here’s how each works in Orange.

ADU Builders in Orange

Orange is genuinely distinct among Orange County cities for ADU work, because the historic core has deep lots where a rear cottage fits naturally, while state law still requires ministerial approval regardless of aesthetic review. That means we can design a detached unit that matches the scale and roofline of a 1920s bungalow and still get it permitted on a predictable timeline. We’ve built garage conversions in the historic districts and new modular units behind mid-century tract homes. The path that works depends on your lot, your tree canopy, and what your foundation can support. ADU Builders in Orange covers the full scope.

Bathroom Remodeling in Orange

Most Orange bathrooms we open up have cast-iron drain stacks and galvanized supply lines that have been in service since the Eisenhower administration. The work usually involves replacing the subfloor around the toilet flange, re-piping the shower valve, and bringing a 1950s electrical circuit up to code for a GFCI-protected bathroom. We handle that in-house, so the plumber, electrician, and tile crew answer to one contract. Bathroom Remodeling in Orange walks through the process.

Kitchen Remodeling in Orange

Kitchen remodeling in Orange runs into a specific set of conditions we don’t see in newer South County homes. The early-1900s Craftsman and Spanish Colonial bungalows in Old Towne have shallow wall cavities, unlevel floors, and plumbing that often dates to the original build, so cabinet runs need custom fillers and shimming rather than off-the-shelf boxes. The 1950s and 60s tract homes east of Tustin Avenue usually have more standard framing, but their electrical panels were sized for a single-oven era. Adding a modern induction range, a second oven, and under-cabinet lighting means a panel upgrade on most of those jobs. Whatever the era, kitchens in Orange also need cooling that can keep up with inland summer heat, especially when the cooktop and oven are running. Our crew handles every part of the remodel without subcontractor handoffs, from the first stud inspection to the final coat of paint. The kitchen work we do in Orange follows the same approach as our broader Kitchen Remodeling service, just tuned to the houses we actually find here.

Cabinet Replacement and Refacing

Signs you need it

Drawer slides bind, door hinges sag, or the boxes have swelled from decades of coastal humidity drift, and refacing the existing boxes no longer makes sense on a house where the layout is sound but the cabinets are end-of-life.

What it costs in Orange

Cabinet replacement and refacing in Orange typically runs from $12,000 to $35,000 depending on whether you’re replacing a 10-foot galley or a full perimeter kitchen with custom upper runs.

How we do it

We remove the existing boxes, shim and level the base run against old Orange subfloors, and install new cabinets on cleats and scribe moldings so the run sits flat even where the floor drops an inch over eight feet.

Countertop and Backsplash Installation

Signs you need it

Laminate tops are peeling at the seams, grout is cracking repeatedly, or you’re already opening walls for electrical work and want to replace the counters in the same phase instead of living with a half-finished kitchen.

What it costs in Orange

Countertop and backsplash work in Orange falls between $4,000 and $12,000, with the spread driven by slab material, linear feet of backsplash, and whether the old counters come out cleanly or fight you the whole way.

How we do it

We template the counters only after the base cabinets are set and leveled, cut the slab for an undermount sink on-site where the seams land cleanly, and set the backsplash on a flat substrate we’ve prepped rather than hoping the old plaster is straight.

What Kitchen Remodeling Costs in Orange

Item Typical range in Orange
Cabinet replacement and refacing $12,000 – $35,000
Countertop and backsplash installation $4,000 – $12,000
Full kitchen remodel (combined scope) $25,000 – $60,000

How much does a kitchen remodel cost in Orange?

A full kitchen remodel in Orange typically runs $25,000 to $60,000, with older homes skewing higher because of electrical panel upgrades, subfloor leveling, and plumbing replacement. The final number depends on your cabinet grade, countertop material, and what your walls reveal once they’re open. Call (833) 589-8273 for a line-item quote.

Will the price change once work starts?

Only if the work scope changes, which we document in writing before proceeding. Older Orange homes sometimes hide surprises behind plaster, so we build a contingency line into the estimate and walk you through every finding before any dollar is spent. Call (833) 589-8273 and we’ll show you exactly how our quotes are structured.

What pushes Orange pricing up is the age of the house: pre-1950 foundations often need leveling before cabinets or walls go in, and electrical service upgrades are common before any ADU or kitchen appliance package.
