ADU Company in Orange, CA

Kitchen remodeling in Orange usually means working inside a 1910s Craftsman bungalow in Old Towne or a 1960s tract home near the 55, and the two jobs require very different approaches. We’re Newport Beach ADU Builders, and we’ve served Orange since 2016 as a full-service ADU and remodeling contractor. That means we handle the kitchen, the bath, and the ADU under one contract, so you’re not juggling three companies for one property. Call (844) 934-0236 for a free estimate on any of it.

Why Orange Homes Are Different

Orange is one of the few Orange County cities with a large stock of pre-war single-family homes on generous lots in the Old Towne historic district, so ADU work here is dominated by designing detached units and garage conversions that respect Old Towne’s historic design-standards overlay while still meeting state ADU law. That’s a balancing act you won’t face in neighboring Anaheim or Santa Ana. Old Towne and the surrounding streets are filled with 1910s to 1940s Craftsman and Spanish Colonial bungalows on deep lots, many with detached single-car garages at the rear. Those garages are often the only legal buildable spot for an ADU, but historic-district design review on roof pitch, siding, and windows can add weeks before a permit moves. We plan for that review timeline and match bungalow detailing up front, so the unit looks like it belongs.

The rest of Orange is mostly 1950s to 1970s tract homes on smaller lots, where the conversation shifts to attached conversions and interior remodels. Inland North Orange County heat means ADUs here need real cooling and shading rather than the coastal-passive approach used a few miles west. The dry Santa Ana wind season also raises fire-hardening questions for rear-yard units, which is why we spec James Hardie fiber-cement siding on most Orange builds. It holds up better than cheaper siding in high-heat, low-moisture conditions.

Our Main Orange Services

Orange homeowners call us most often about two things: adding an ADU to a deep Old Towne lot or rear garage, and remodeling bathrooms in older homes where plumbing and layout need real rethinking. Here’s what each involves locally.

ADU Builders in Orange

Most Orange ADU projects start at the rear of the lot, where a detached single-car garage from the 1920s or 1930s is doing nothing useful. We convert those garages or build new detached units behind them, working inside Old Towne’s historic-design overlay from day one. State ADU law gives you rights, but the city’s design review still moves at its own pace. We submit drawings that already match bungalow roof pitches, window proportions, and siding details, which keeps the review from stalling. We’re authorized builders for Abodu, Cover, Dvele, Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, and James Hardie products, so factory-built and site-built options are both on the table.

Bathroom Remodeling in Orange

Bathrooms in Orange’s older homes are often 5-by-8 rooms with cast-iron plumbing that’s been in the ground since the Coolidge administration. Remodeling here usually means reconfiguring the footprint, updating drain lines, and adding ventilation that handles inland summer heat without turning the room into a sauna. We handle the full bathroom remodel under the same contract as your ADU or kitchen work, which matters when you’re updating a primary bath and adding an ADU at the same time. One crew, one schedule, one point of accountability. Details are on our Bathroom Remodeling in Orange page.

Kitchen Remodeling in Orange

Kitchen remodeling in Orange is a different animal depending on whether you’re in a 1920s Old Towne bungalow with a galley kitchen that’s never been touched, or a 1960s tract home where the layout is workable but everything is worn out. In bungalows, we’re usually finding knob-and-tube remnants, sagging floors under old appliances, and kitchens that were never designed for a refrigerator wider than 30 inches. In tract homes, the job is more straightforward: gut, reconfigure, reinstall with modern systems. Either way, Orange’s inland heat means ventilation and cooling matter more than they do in coastal kitchens, and we spec range hoods and HVAC tie-ins accordingly. We handle the full kitchen remodel as part of our Kitchen Remodeling service, and we can fold it into the same contract as an ADU build so you’re not coordinating two contractors on one property.

Full Galley Kitchen Gut

Old Towne bungalows almost always have narrow galley kitchens where storage is minimal and original plumbing is at the end of its life. This job means opening the space, replacing everything behind the walls, and reworking the layout so the kitchen functions at modern standard without gutting the home’s historic character.

Signs you need it

Floor joists squeak or dip near the range, cabinets are original and water-stained, and you can’t open the oven and dishwasher at the same time without blocking the walkway.

What it costs in Orange

A full galley kitchen gut with new plumbing, electrical, cabinetry, counters, and appliances in Orange typically runs $45,000 to $75,000 depending on structural repairs and finish level.

How we do it

We demo to the studs, repair or sister any compromised floor framing, rough in new plumbing and electrical, then rebuild with full-height cabinetry, a vented range hood, and layout that opens the galley without moving load-bearing walls.

Cosmetic Kitchen Refresh

Many Orange tract homes from the 1960s and 1970s have kitchens with solid bones but tired surfaces. This job keeps the existing layout and updates the finishes, fixtures, and lighting so the room looks and works current without a full gut.

Signs you need it

Cabinets are structurally sound but dated or peeling, counters are chipped laminate or old tile, and the sink and faucet are original or leaking.

What it costs in Orange

A cosmetic kitchen refresh in Orange typically falls between $18,000 and $30,000, depending on counter material, cabinet refacing versus replacement, and plumbing fixture upgrades.

How we do it

We reface or paint existing cabinet boxes, install new countertops and backsplash, replace the sink and faucet, swap dated light fixtures, and add under-cabinet lighting and a properly vented hood.

Kitchen Layout Reconfiguration

Some Orange kitchens are stuck with a layout that worked in 1965 but fights the way anyone cooks now. This job moves sink, range, or island positions within the existing footprint, or opens the kitchen to a dining area by removing a non-load-bearing partition.

Signs you need it

The work triangle is broken, the range is jammed against a side wall, there’s no place for more than one person to prep, or the kitchen is walled off from the family space.

What it costs in Orange

Reconfiguring a kitchen layout in Orange ranges from $30,000 to $50,000, with the final number driven by how much plumbing and electrical has to move.

How we do it

We verify which walls are load-bearing, reroute plumbing and electrical for the new positions, install the reconfigured cabinetry and appliances, and patch and finish the opened spaces so the room flows into the adjacent living area.

What Kitchen Remodeling Costs in Orange

Item Typical range in Orange
Cosmetic kitchen refresh $18,000 – $30,000
Kitchen layout reconfiguration $30,000 – $50,000
Full galley kitchen gut $45,000 – $75,000

Two things push kitchen prices up in Orange more than most cities. First, Old Towne permits trigger design review when the kitchen is part of a larger project touching exterior walls. Second, older bungalow framing often needs structural repair once we open the walls. We give upfront written quotes with line items, and the price we bid is the price you pay, no change-order games.

How long does a kitchen remodel take in Orange?

A cosmetic refresh runs two to three weeks. A full gut with structural repair runs six to ten weeks in Orange, longer if a historic-design review timeline overlaps. We schedule the permit path before demo begins so the work isn’t stalled mid-project. Call (844) 934-0236 for a timeline specific to your house.

Will my kitchen remodel trigger Old Towne design review?

Interior kitchen work alone does not require historic-design review. If your project touches exterior walls, windows, or rooflines, review kicks in. We file interior and exterior scopes separately when possible so the kitchen keeps moving while design review runs its course. Call (844) 934-0236 and we’ll tell you which path your house falls into.

Brands We Service in Orange

We build and install across the brands Orange homeowners already know: Tuff Shed for budget-tier conversions, Cover and Abodu for design-forward prefab, and James Hardie siding for fire-hardened, low-maintenance exteriors on every build where it fits. Parts and finish materials stock fast through our local suppliers, and we match the brand to your lot, not the other way around. See the full lineup on our brands page.

Pricing for ADU Company in Orange, CA

Service Typical range in Orange
Cosmetic kitchen refresh $18,000 – $30,000
Kitchen layout reconfiguration $30,000 – $50,000
Full galley kitchen gut $45,000 – $75,000

In Orange, the biggest price drivers are structural surprises inside old bungalow walls and any historic-design review that shapes exterior-facing work. We quote fixed prices after a site walk, and that quote does not move unless you change the scope. That’s a promise, not a sales line.

Neighborhoods We Serve in Orange

We work in every Orange ZIP code: 92859, 92862, 92863, and 92864. Old Towne and its surrounding historic blocks make up the bulk of our ADU and kitchen work, but we’re regularly in the tract-home neighborhoods east of the 55 and the unincorporated edges of the city as well.

  • Old Towne Orange
  • Orange Park Acres
  • El Modena
  • Santiago Hills
  • Mabury Park

For most Orange jobs, we can have someone at your door for a site walk within a few business days of your call. Old Towne projects get a little extra time on the front end because we review the historic-design overlay before we quote.

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."

— Diego Castillo

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

— Malik Nash

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

— Steven Nguyen
