ADU Company in Orange, CA

Kitchen remodeling in Orange means working inside homes built between the 1920s and the 1960s, where the original footprint was never designed for how families cook and gather today. We’re Casita ADU Builders, and while our name says ADU, our in-house kitchen remodeling team exists because nearly every detached ADU we build in Orange also needs a complete kitchen, and most homeowners would rather keep one contract than juggle two crews. The older ranch and Craftsman homes here carry narrow galley kitchens, low ceilings, aging electrical panels, and layouts that fight you at every turn. Call (877) 658-7475 when you’re ready to see what your Orange kitchen can become.

Why Orange Homes Are Different

Orange is not Santa Ana and it’s not Anaheim. The city still holds one of Orange County’s largest concentrations of pre-1960 single-story ranch homes and early-1900s Craftsman bungalows, particularly inside and around the Old Towne Historic District. That housing stock changes the work. A 1955 ranch kitchen in the 92865 ZIP code typically has a service panel rated for about half of what a modern induction range, dishwasher, and ADU subpanel demand. A Craftsman home inside the Old Towne overlay often has original fir framing, plaster walls, and a floor plan never meant for an open-concept island. Kitchens here are smaller, darker, and more structurally constrained than what you find in newer south Orange County tracts.

The climate matters too. Orange summers run hot and dry, and Santa Ana wind events push dust into every gap around windows and vents. That makes ventilation, range hoods, and heat-tolerant finishes more than aesthetic choices. We also see mature orange and avocado trees shading rear kitchen additions, which is lovely until the root zone intersects your sewer line or foundation trench. When we remodel a kitchen in Orange, we plan for the house’s actual age, the panel’s actual capacity, and the specific side of the historic overlay line your property sits on.

Our Main Orange Services

Most Orange homeowners first reach out about one of two things: building an ADU in the backyard, or remodeling a bathroom inside the main house, often as part of an ADU project or a multigenerational living setup. Here’s what each looks like in Orange specifically.

ADU Builders in Orange

Orange’s generous lot sizes and the city’s recent ADU ordinance updates make detached rear-yard units and garage conversions the two most workable project types. If your home sits in Old Towne, the design review process will pay close attention to roofline compatibility and window proportions, and we navigate that review as a routine part of the job. Outside the historic overlay, a 1950s tract lot often gets a prefab or panelized ADU approved without the same level of scrutiny. We work across Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab so your unit matches your lot, your budget, and the review standard your property actually faces.

Bathroom Remodeling in Orange

Bathrooms in Orange’s older homes tend to be small, with original cast-iron plumbing, limited venting, and tile set over drywall that was never meant to carry decades of humidity. A 1958 tract bathroom often hides a failing shower pan or a floor joist that’s been quietly rotting under the toilet flange. We handle the full remodel in-house, which matters when you’re renovating a hall bath alongside a new ADU and don’t want coordination gaps between the two projects. See Bathroom Remodeling in Orange for what this looks like in your specific home.

Kitchen Remodeling in Orange

Kitchen remodeling in Orange usually starts with a house built in the 1950s or 1960s whose original kitchen is still working against the current owner. The room is narrow, the cabinets hit the ceiling at 7 feet, the range is boxed into a corner, and the dining wall blocks what should be the most-used room in the house. Our in-house Kitchen Remodeling team handles the structural and finish work without handing you off to a second contractor, which matters when a kitchen remodel in Orange also involves moving plumbing, upgrading the panel, or tying into a new ADU’s electrical feed.

Full Kitchen Gut and Relayout

Signs you need it

The existing layout forces you to walk through the cooking zone to reach the refrigerator, or the sink is completely cut off from the rest of the work triangle.

What it costs in Orange

A full gut and relayout in Orange typically runs $28,000 to $65,000 depending on whether you move plumbing, open walls, or upgrade the electrical panel.

How we do it

We demo to the studs, reframe openings, reroute plumbing and electrical, hang drywall, and set the new cabinet and appliance layout to match the way you actually cook.

Cabinet, Counter, and Finish Refresh

Signs you need it

The cabinet boxes are sound but the doors are worn, the counter is chipped or stained, and the kitchen reads as the 1982 original even though the house has otherwise been updated.

What it costs in Orange

Refacing or replacing cabinets, adding a new counter, and updating hardware and fixtures in Orange generally lands between $9,000 and $22,000.

How we do it

We pull the existing doors and counters, install new cabinet fronts or full replacement boxes, set the counter slab, and finish with hardware, sink, and faucet in one pass.

What Kitchen Remodeling Costs in Orange

Item Typical range in Orange
Full kitchen gut and relayout $28,000 – $65,000
Cabinet, counter, and finish refresh $9,000 – $22,000
Appliance and lighting package (range, hood, dishwasher, recessed lighting) $4,500 – $11,500

Two things push Orange kitchen pricing higher than you might expect. First, the age of the panel. If your 1957 home still runs a 100-amp service, adding an induction range, a proper range hood, and counter receptacles can force a panel upgrade that changes the total price. Second, Old Towne properties under historic review may require custom millwork or window sizing that a 1965 tract home never triggers.

How long does a kitchen remodel take in Orange?

A refresh with new cabinets, counters, and finishes usually takes 3 to 5 weeks. A full gut that moves plumbing and walls typically runs 6 to 10 weeks, plus any review time if the property falls inside the Old Towne overlay.

Will a kitchen remodel trigger a panel upgrade in my Orange home?

It often does on houses built before 1965. Modern code requires dedicated circuits for most appliances, so if your panel is still at 100 amps or less, budget $2,500 to $5,000 for the upgrade as part of the project. Call (877) 658-7475 for an exact read on your home.

What Orange Customers Say

★★★★★ 4.8 from 4+ reviews

"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."

— Robert Gallagher

"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."

— Aisha Prince

"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."

— Maria Martinez
