ADU Company in Orange, CA

Kitchen remodeling in Orange means working inside homes built between 1920 and 1970, where floor plans were designed for a different era of cooking and entertaining. Our kitchen work here centers on opening cramped galley kitchens in Old Towne bungalows, replacing water-damaged cabinets in mid-century ranches, and updating layouts in the stucco tract homes that fill the neighborhoods east of the 55. Call (877) 588-6929 and we’ll walk you through a realistic plan for your specific home.

Why Orange Homes Are Different

Orange’s housing stock is older and more architecturally distinct than most of North Orange County. Central Orange is dominated by 1920s – 1940s wood-frame bungalows and Spanish Revival cottages on 6,000 – 8,000 sq ft lots, with mid-century tract homes and 1960s-70s stucco ranches filling out the neighborhoods east and north. Those pre-war homes have real dimensional lumber framing, plaster walls, and foundations that have settled for 80 to 100 years. A kitchen remodel in a 1930s Old Towne bungalow is a different job than the same remodel in a 1990s Anaheim Hills tract house. The framing is uneven. The plumbing is original or partially updated. The electrical panel is often undersized for modern appliances. None of this is a reason to avoid the project. It’s a reason to plan for it from the start, which is what we do.

Climate matters too. Inland North Orange County gets hot, dry summers and periodic Santa Ana wind events. That means venting a range hood properly matters more here than it does in coastal cities. It means choosing finishes that won’t warp or fade under direct afternoon sun. And it means thinking about how the kitchen connects to the rest of the house’s cooling load. Old Towne’s wide alleys and deep lots give Orange homeowners more flexibility than most, but the historic overlay in the Old Towne District adds design review requirements that don’t exist elsewhere in Orange County. If your home is in the historic district, we’ll factor that into the plan from day one.

Our Main Orange Services

Most Orange homeowners call us for one of two things: building an accessory dwelling unit on their lot, or remodeling a bathroom inside the main house. Both are services we handle end to end, with permits pulled and inspections passed.

ADU Builders in Orange

Orange’s wide, deep lots and rear alley access in the Old Towne Historic District make this city unusually well suited for accessory dwelling units. But the historic overlay means any ADU proposal inside that district has to clear design review and compatibility standards that don’t apply in Tustin or Anaheim. Massing, roof pitch, and window proportions all get scrutinized. We’ve navigated that process repeatedly and can tell you up front whether your lot and your home’s historic status will make the project straightforward or slow. From prefab brands like Abodu and Cover to fully custom site-built units, we’ll match the structure to your lot, your budget, and the city’s requirements. ADU Builders in Orange.

Bathroom Remodeling in Orange

Bathrooms in Orange’s older housing stock tend to be small, with original cast-iron plumbing and tile set in thick mortar beds. Demolition is slower, and waterproofing details matter more in a 1930s wood-frame home than in a newer slab-on-grade build. We handle the full remodel: replacing the old tub or shower with a properly waterproofed system, updating the vanity and fixtures, and bringing the plumbing and electrical up to current code. If your home is in the Old Towne Historic District, we’ll also coordinate any exterior-visible changes with the city’s design review process. Bathroom Remodeling in Orange.

Kitchen Remodeling in Orange

Kitchen remodeling in Orange usually comes down to one of three jobs: opening up a closed-off 1920s – 1940s kitchen, gutting and replacing a tired mid-century layout, or modernizing a 1960s-70s tract home kitchen that’s still running on original cabinets and laminate counters. The homes here weren’t built for open-concept living, so most projects involve some structural work: removing a load-bearing wall, relocating plumbing, or upgrading an undersized electrical panel. We handle the full scope, from permits and structural engineering to cabinets, counters, and finish work. If you’re weighing a full kitchen remodel against a lighter refresh, our Kitchen Remodeling resource covers the decision in more detail.

Galley Kitchen Opening

Signs you need it

The kitchen is a narrow corridor where two people can’t work without bumping elbows, and the only fix is removing the wall between it and the dining or living room.

What it costs in Orange

Plan on $35,000 to $65,000 depending on whether the wall is load-bearing and how much plumbing and electrical has to move.

How we do it

We start with a structural engineer’s assessment of the wall, pull the permit, install a beam if needed, then rebuild the kitchen as an open space with a peninsula or island.

Full Kitchen Replacement

Signs you need it

The cabinets are delaminating, the layout wastes half the floor area, and the appliances, plumbing, and electrical all need to be brought up to current code.

What it costs in Orange

Expect $45,000 to $80,000 for a complete gut and rebuild in a typical Orange home.

How we do it

We demolish to the studs, relocate plumbing and electrical as needed, install new drywall, flooring, cabinets, counters, and appliances, then handle all inspections through final sign-off.

What Kitchen Remodeling Costs in Orange

Item Typical range in Orange
Galley kitchen opening with beam $35,000 – $65,000
Full kitchen replacement $45,000 – $80,000
Cabinet and counter refresh $15,000 – $30,000

How long does a kitchen remodel take in Orange?

Most full kitchen remodels in Orange run 6 to 10 weeks from demolition to final inspection. Homes in the Old Towne Historic District can add 2 to 4 weeks for design review if exterior-visible changes are involved.

Will my Orange kitchen remodel need a permit?

Yes. Any work that moves walls, relocates plumbing, or changes electrical requires a permit from the City of Orange. We pull all permits and schedule every inspection. Call (877) 588-6929 for an exact quote on your project.

Brands We Service in Orange

We work with James Hardie fiber-cement siding for durable, fire-resistant exterior finishes on ADU projects, and we’re fluent in the Abodu, Cover, and Tuff Shed prefab platforms. That brand range means we can match a structure to your budget and your lot instead of forcing one product onto every project. Our brands page breaks down the tradeoffs.

If the home sits in the Old Towne Historic District, design review fees and compatibility requirements add another layer of cost and time.

What Orange Customers Say

★★★★★ 4.8 from 4+ reviews

"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."

— Riya Reddy

"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."

— Travis Norris

"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."

— Emily Reed
