ADU Company in Orange, CA
Kitchen remodeling in Orange means working with homes that were built long before open floor plans and modern appliance sizes existed. Many of the kitchens we open up in Old Towne’s citrus-era bungalows and the 1950s-70s tract ranches across east Orange were designed around a single cook, a narrow refrigerator slot, and zero thought given to counter seating or ventilation. Sentinel ADU Builders has served Orange since 2017, and we handle kitchen remodels alongside ADU construction and bathroom work, so whether you’re modernizing a pre-war kitchen or adding a full ADU with its own kitchen, one contractor carries the job from permit to punch-list. Call (855) 341-3461 for a free estimate.
Why Orange Homes Are Different
Orange sits in the Santa Ana River plain, inland from the coast, so summers run hotter and drier than what homeowners in Huntington Beach or Newport assume. A kitchen or ADU remodel here has to plan for real cooling load, not coastal-mild ventilation. Add the Santa Ana wind events that blow through in late summer and fall, and exterior work has to be sequenced carefully around heat and wind, especially when we’re cutting new door openings or swapping a garage into living space.
The housing stock is split in two. Old Towne and the blocks around the Plaza are dominated by pre-1940s citrus-era bungalows and Craftsman homes with detached single-car garages on rear alleys. Those garages are frequently undersized, sometimes on shared driveways, and many sit directly on a property line or within feet of a neighbor’s wall. The other half of Orange – especially east and southeast – is 1950s-1970s tract ranch homes, which are prime candidates for ADU conversions but often have tight side setbacks and kitchens that were built for a 30-inch range and no dishwasher. Both types of home demand a contractor who reads site constraints before promising a layout.
Our Main Orange Services
Orange homeowners call us most about two things: building an ADU on a lot that wasn’t designed for one, and fixing a bathroom that’s decades past its original 1970 spec.
ADU Builders in Orange
Detached garage conversions and backyard casitas dominate ADU work in Orange, especially behind Old Towne’s citrus-era bungalows where the garage opens onto a rear alley or shared driveway. The question locals ask is whose wall is the property line, and how a rear unit gets utilities and access without disturbing a historic streetscape. We work across seven prefab platforms – including Cover, Dvele, and Boxabl – alongside site-built construction, so the recommendation follows your lot, not the inventory. ADU Builders in Orange covers the full decision between prefab and custom.
Bathroom Remodeling in Orange
Many Orange bathrooms are original to a pre-1940s Craftsman or a mid-century tract home, meaning cast-iron plumbing, zero waterproofing behind the tile, and a floor plan that doesn’t support two people getting ready at once. We remodel bathrooms under the same permit and project plan as kitchens and ADUs, so if you’re adding a unit and refreshing the main house, you aren’t juggling three contractors. Bathroom Remodeling in Orange has the full scope and local pricing.

Kitchen Remodeling in Orange
Kitchen remodeling in Orange usually means one of two jobs: gutting a pre-war kitchen that was built for a single cook and no modern ventilation, or reconfiguring a 1950s-70s tract kitchen where the refrigerator and range are crammed into a narrow leg of the room. Both are common across Orange’s split housing stock – the citrus-era bungalows near the Plaza and the ranch homes through the east side. The heat matters too: inland Orange kitchens need real exhaust and cooling planning, not a coastal-mild assumption, and the Santa Ana wind season affects when we schedule exterior vent work. We plan the remodel around the lot, the house era, and how you actually use the space. Kitchen Remodeling is one of the three trades we handle under a single project plan.
Galley Kitchen Reconfiguration
Signs you need it
The kitchen is a narrow corridor, two people can’t pass each other, and every meal prep happens on the same 18 inches of counter.
What it costs in Orange
Reconfiguring a galley kitchen in Orange typically runs $25,000 to $45,000 depending on how much load-bearing wall has to move and what the plumbing stack relocation involves.
How we do it
We open the walls to confirm bearing points and existing plumbing, then redesign the layout around a single work triangle and ventilation path, pulling permits before any structural cut is made.
Full Kitchen Gut and Rebuild
Signs you need it
Water damage under the sink, cabinets that no longer close, wiring that can’t support a modern range or dishwasher, or a layout that’s never worked since you bought the house.
What it costs in Orange
A full kitchen gut and rebuild in Orange typically lands between $60,000 and $90,000, with cabinets, counters, flooring, framing, plumbing, and electrical all replaced in one permit cycle.
How we do it
We demo to the studs, correct any framing or subfloor damage, then rebuild with new rough-in plumbing, electrical, insulation, cabinetry, and finishes, with one crew and one project lead from first cut to final walkthrough.
What Kitchen Remodeling Costs in Orange
| Item | Typical range in Orange |
|---|---|
| Galley kitchen reconfiguration | $25,000 – $45,000 |
| Full kitchen gut and rebuild | $60,000 – $90,000 |
| Cabinet refacing with new counters and backsplash | $18,000 – $35,000 |
The two big price drivers in Orange are the age of the house and the state of the original plumbing and wiring. A pre-war bungalow with cast-iron drain lines and knob-and-tube remnants will push a kitchen remodel toward the top of the range faster than a 1970s tract home on copper and modern conduit, which is why we give written line-item quotes after we’ve opened or inspected the walls, not before.
Do I need a permit for a kitchen remodel in Orange?
Yes, any kitchen remodel that moves plumbing, electrical, or structural walls requires a permit through the City of Orange building division. We pull all permits and handle inspections as part of the project. Call (855) 341-3461 for an exact scope review.
What does Cabinets replacement cost in Orange?
Cabinet refacing with new counters and backsplash typically runs $18,000 to $35,000 in Orange. Full replacement falls inside the $60,000 to $90,000 gut-and-rebuild range when it’s part of a full kitchen project. Call (855) 341-3461 for a fixed line-item quote.

What pushes ADU price up in Orange more than anything is site access and setback conditions – a detached garage on a narrow alley with shared utility lines costs more to convert than a clear backyard on a 7,000-square-foot east Orange lot. We write fixed, line-item quotes before the build starts and we don’t change the price once work is underway unless you change the scope.
