ADU Company in Orange, CA

Kitchen remodeling in Orange often means working inside a 1920s California bungalow where the existing footprint was never designed for a modern layout, or a 1950s ranch with a galley kitchen that opens straight into the laundry room. We’ve remodeled kitchens across Orange’s ZIP codes long enough to know that the job usually starts with the walls, not the cabinets: rewiring, re-plumbing, and undoing decades of questionable additions before the new design goes in. Whether your kitchen is in an Old Towne historic home or a midcentury tract house closer to Chapman University, call us at (877) 265-7231 for a free estimate and we’ll walk the space with you.

Why Orange Homes Are Different

The homes we work on in Orange fall into two broad camps, and each one changes how a remodel is planned. In the Old Towne Historic District and surrounding pre-1940 neighborhoods, we’re working on bungalows with plaster walls, minimal insulation, and floor plans where the kitchen was originally a closed-off service room at the back of the house. Moving a wall or widening a doorway in these homes isn’t a design decision you make on a whim, because the City’s historic review process can weigh in when changes are visible from the street. The structural work is also different: pier-and-post foundations instead of slabs, and framing members that don’t always match modern dimensions.

The second camp is the 1950s and 1960s ranch tracts that spread out from the Plaza. Those homes have bigger lots and more forgiving layouts, but the kitchen challenges are electrical and mechanical rather than structural. A ranch in the 92862 or 92867 ZIP often still has a 100-amp panel feeding everything, and adding a wall oven, a second sink, or an induction cooktop means a panel upgrade before the appliances are even ordered. Orange’s summers are hot and dry, so ventilation and cooling matter in a remodeled kitchen far more than they would in a coastal city. The Santa Ana winds in fall also mean we’re thoughtful about exterior penetrations and weather sealing around any new venting.

Our Main Orange Services

Most Orange homeowners reach out to us for one of two reasons: they want to add a detached or attached ADU in the backyard, or they want to update a bathroom that’s still living in the era the house was built. These two projects tend to surface together, especially when a family is adding on instead of moving.

ADU Builders in Orange

Building an ADU in Orange means different things depending on which block you live on. In the 1950s tracts east of the 55, we usually have room to work with: a detached unit in the rear yard, a garage conversion, or an attached addition with its own entrance. In the Historic District, the conversation changes quickly. Any roofline or second-story change that’s visible from the street can trigger a compatibility review, which shapes everything from the roof pitch to the window style. We help homeowners work through that process before a plan is finalized, and we build with James Hardie fiber-cement exteriors and other materials that hold up through the Santa Ana season. See how we approach Orange’s specific conditions on our ADU Builders in Orange page.

Bathroom Remodeling in Orange

Bathrooms in Orange’s older homes are often the smallest room in the house and the hardest to update without opening a wall or two. The 1920s bungalows typically have a single bath with a clawfoot tub or a tight shower stall, and the ranches from the 1950s and 1960s have original pink or blue tile that’s been patched and re-caulked a dozen times. We regularly replace cast-iron drain lines, repair water-damaged subfloors, and bring the electrical up to code for a proper exhaust fan. If the primary bath is the project, we coordinate it with the rest of the house so you’re not paying for a plumber to visit twice. Details on our approach are on the Bathroom Remodeling in Orange page.

Kitchen Remodeling in Orange

A kitchen remodel in Orange is really two projects in one: updating the layout and surfaces you see every day, and correcting the infrastructure hidden behind the walls that older homes so often bring with them. A 1920s bungalow near Old Towne will need a different set of decisions than a 1960s ranch out toward the Santiago Creek area, from where the range can sit relative to existing venting, to whether the panel can handle a modern appliance package. We plan both halves of the job before the first cabinet is ordered, because the infrastructure work dictates what the finished kitchen can actually be. This is the core of what we do, and you can read more about our overall approach on the Kitchen Remodeling hub page.

Full Gut Remodel

Signs you need it

The layout doesn’t function for how you cook now, the electrical is original, or there’s water damage under the sink that’s gone further than a cabinet replacement can fix.

What it costs in Orange

A full gut remodel of a kitchen in Orange typically runs from $35,000 to $65,000 depending on square footage, structural surprises, and the finish level you choose.

How we do it

We demo to the studs, upgrade the electrical and plumbing to current code, then rebuild the kitchen with new drywall, flooring, cabinetry, counters, and appliances.

Cabinet and Countertop Refresh

Signs you need it

Your layout works fine but the doors are delaminating, the hinges are worn, or the countertops are scratched and stained beyond resurfacing.

What it costs in Orange

Replacing cabinets and countertops in Orange usually falls between $12,000 and $28,000, with the spread driven by cabinet construction and countertop material.

How we do it

We take precise measurements, confirm the cabinet boxes can support the new counter weight, then install the new cabinets, counters, and a matching backsplash with sealed seams.

What Kitchen Remodeling Costs in Orange

Item Typical range in Orange
Full gut remodel $35,000 – $65,000
Cabinet and countertop refresh $12,000 – $28,000
Electrical panel upgrade (often required) $3,000 – $6,000

Will a kitchen remodel in an old Orange home cost more than in a newer one?

Usually yes. Pre-1940 homes in Orange often have plaster walls, dated wiring, and no dedicated circuits for modern appliances, so addressing these before finish work adds cost you wouldn’t see in a newer tract home. Call (877) 265-7231 and we’ll walk you through what your specific house will need.

How long does a kitchen remodel take in Orange?

Most full kitchen remodels in Orange take four to eight weeks once we start, with cabinet lead times and any historic review requirements adding time on the front end. We’ll give you a written schedule before the first crew arrives.

Brands We Service in Orange

When we build ADUs in Orange, we work across the brands homeowners are already researching, including our brands like Plant Prefab, Abodu, and Tuff Shed, with James Hardie fiber-cement specified on exteriors for durability and fire resistance. That brand-agnostic approach means the system fits your lot and budget, not our inventory.

Pricing for ADU Company in Orange, CA

Service Typical range in Orange
Kitchen full gut remodel $35,000 – $65,000
Kitchen cabinet and countertop refresh $12,000 – $28,000
Kitchen electrical panel upgrade $3,000 – $6,000
ADU site-built detached unit $250 – $450 per sq ft
Prefab ADU (Plant Prefab, Abodu systems) $200 – $350 per sq ft
Tuff Shed-based studio conversion $50,000 – $120,000
ADU garage conversion $120,000 – $200,000
Bathroom full remodel $18,000 – $40,000
Bathroom shower replacement $8,000 – $15,000
Bathroom tub-to-shower conversion $6,000 – $12,000

In Orange, the price of a kitchen remodel gets pushed up by hidden conditions in older homes: undersized sewer laterals, cast-iron drains, or a panel that tops out at 100 amps and can’t feed a modern kitchen. On the ADU side, the Historic District’s compatibility review can add time and design iterations that newer neighborhoods don’t carry. We give you a written, itemized quote before the job starts, and we don’t change that number unless you change the scope.
