ADU Company in Orange, CA
Kitchen remodeling in Orange is shaped by the city’s housing stock more than any single design trend, because a large share of the homes here were built between the 1890s and 1960s with floor plans that no longer match how families actually cook and gather. Fullerton ADU Builders has served Orange since 2017, and our work in this city tends to involve opening up compartmentalized kitchens in Craftsman bungalows and mid-century tract homes, upgrading old electrical and plumbing inside walls that have stood for sixty to a hundred years, and adding the square footage that today’s kitchens need without fighting the lot lines. We also build ADUs on these same Orange properties, and we know how to sequence a kitchen remodel alongside an ADU project so both jobs share one contractor, one schedule, and one set of trade crews. Call (877) 801-4497 to talk through what your Orange home can support.
Why Orange Homes Are Different
Orange is not a single housing market. The landmarked Old Towne district holds late-1800s Victorians and early-1900s Craftsman bungalows on long, narrow parcels where the rear of the lot often meets an alley rather than a wide backyard. Homeowners in these blocks face a different set of kitchen and ADU questions than homeowners in the mid-century tracts east and south of the 55, where the houses were framed in the 1950s and 1960s and the lots, while larger, still carry their own quirks like post-and-beam construction and original slab plumbing. The historic-preservation overlay in Old Towne means any exterior change, including a kitchen bump-out or a wall penetration for a new range hood, can trigger design review. Inside the house, the constraints are quieter but just as real: balloon framing, undersized floor joists, and electrical panels that were sized for a 1950s appliance load, not a modern induction cooktop and double oven.
Climate here is inland North Orange County. Warm, dry summers and mild winters mean kitchens in Orange are designed for cross-ventilation and shade, and outdoor cooking and dining areas get real use nine months of the year. We regularly specify larger window openings, deeper overhangs on any kitchen addition, and vent hoods sized for the heat output of serious cooking equipment because the indoor-outdoor relationship is different in Orange than it is in coastal cities. Mature citrus trees on many Orange lots also matter when you are planning a kitchen addition: a 40-year-old orange tree can shape the footprint of a bump-out more than any zoning line will.
Our Main Orange Services
Orange homeowners call us most often about two projects: building a new ADU on the property and remodeling a bathroom in the primary home. Both are covered below, with dedicated Orange pages that go deeper on each.
ADU Builders in Orange
An ADU in Orange is a different conversation than an ADU in most neighboring cities because of the historic-district overlay. A detached unit that sails through the planning counter in Anaheim can get kicked back in Old Towne over setbacks, roof pitch, and window proportions that must read as compatible with the surrounding Victorian and Craftsman blocks. We work that process from the first site visit, and we match the unit to the lot, not the other way around: a rear-alley garage conversion on a narrow Old Towne parcel, a prefab panel system tucked into a mid-century side yard, or a foldable unit where access is tight. Full details are on the ADU Builders in Orange page.
Bathroom Remodeling in Orange
Bathrooms in Orange’s older homes tend to be small, often five by seven feet, and many still sit on original cast-iron waste lines. A remodel here usually means reconfiguring a tight footprint, correcting decades of deferred waterproofing, and bringing a 1940s or 1950s bath up to current code without moving walls that cannot be moved. We also remodel bathrooms in the mid-century tracts, where the original tile is often set in a mud bed that has outlived its life. The full scope, including cost ranges, is on the Bathroom Remodeling in Orange page.

Kitchen Remodeling in Orange
Kitchen remodeling in Orange means working inside homes where the original kitchen was small, closed off, and built for a different era of cooking. Old Towne bungalows often have galley kitchens under eight feet wide, while the mid-century tracts east of the Plaza have kitchens with original cabinetry that predates modern appliance dimensions. The climate matters here too: Orange’s warm, dry summers push many of our kitchen projects toward better cross-ventilation, larger window openings, and direct connection to a shaded outdoor cooking or dining area. Kitchen Remodeling is a core trade for us, and in Orange it usually starts with a structural question: what can actually be moved in a house this old?
Cabinet Replacement and Layout Reconfiguration
Signs you need it
Cabinet doors no longer close square, drawer slides are worn out, or the current layout puts the refrigerator, sink, and range far enough apart that cooking in the kitchen feels like a commute.
What it costs in Orange
Cabinet replacement and layout work in Orange typically runs $15,000 to $45,000 depending on run length, finish level, and whether moving plumbing or gas lines is required to change the layout.
How we do it
We measure the existing footprint, confirm which walls are load-bearing and which are not, produce a revised floor plan, remove the old cabinets, and install new ones with the layout corrected for prep-to-cook flow.
Countertops, Backsplash, and Fixtures
Signs you need it
Countertops are chipped, stained, or delaminating, the backsplash is failing, or the sink and faucet are original to a house that has been through forty or more Orange summers.
What it costs in Orange
A surface-level kitchen refresh in Orange, including countertops, backsplash, sink, and fixtures, typically falls between $25,000 and $50,000 depending on material grade and square footage.
How we do it
We template the countertops after the cabinets are set, coordinate the stone or solid-surface fabrication, install the backsplash, and set the sink and fixtures with all plumbing corrected at the wall.
What Kitchen Remodeling Costs in Orange
| Item | Typical range in Orange |
|---|---|
| Cabinet replacement and layout reconfiguration | $15,000 – $45,000 |
| Countertops, backsplash, and fixtures | $25,000 – $50,000 |
| Full kitchen remodel (structural, plumbing, electrical, finish) | $40,000 – $90,000+ |
In Orange, the price moves with the age of the house more than the finish level. A 1920s Old Towne bungalow with balloon framing, a 60-amp panel, and cast-iron waste lines will push a remodel toward the high end because the hidden work is heavier. Fullerton ADU Builders quotes fixed prices with no change orders, so the number we give you before we start is the number on the final invoice.
How long does a kitchen remodel take in Orange?
A full kitchen remodel in Orange takes six to twelve weeks depending on structural work, permit review time, and material lead times. We provide a written schedule before we start and update it weekly as cabinets, stone, and fixtures arrive.
Do you handle the permits for kitchen remodels in Orange?
Yes. We pull all required City of Orange permits for structural, plumbing, electrical, and mechanical work, and we schedule the inspections. Historic-district properties may require additional design review, which we manage as part of the project.
Brands We Service in Orange
We specify James Hardie fiber cement cladding on ADU exteriors and kitchen additions because it holds up to the dry heat and ultraviolet exposure of inland Orange County without the maintenance demand of wood siding. For prefab ADUs, we work directly with Abodu, Cover, and Dvele, among others. See our brands for the full range.

In Orange, two things push prices up consistently: the age of the original structure and the historic-preservation review that applies to exterior work in Old Towne and other designated districts. Foundation depth, panel upgrades, and waste-line replacement are often the quiet drivers on older lots. Every estimate we give is a fixed, written, line-item price, and we do not bill for change orders that we initiated.
Neighborhoods We Serve in Orange
We work throughout the city, from the historic blocks of Old Towne out to the mid-century tracts and newer subdivisions in the 92859, 92862, 92863, and 92864 ZIP codes. Our crews are typically in Orange two to three days per week during active projects, and we schedule site visits to fit the Old Towne permit and design-review calendar rather than working against it.

FAQs About ADU Company in Orange
We are based in Fullerton, roughly fifteen minutes from most Orange neighborhoods, so site visits and active-phase trade work are scheduled on regular routes. Call (877) 801-4497 and we will set a site visit within the week for most Orange properties.
If your property sits within the Old Towne historic district or another designated overlay, exterior changes including a new detached ADU will likely require design review. We prepare the drawings and materials board to meet those standards and manage the application through approval.
Yes. Running both projects under one contractor means one permit set, one schedule, and shared trade crews rather than two separate jobs competing for the same driveway and dumpster space. It also lets us coordinate utility upgrades so the panel and water service are sized once, for both buildings, instead of twice.

What Orange Customers Say
"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."
— Tim Padgett"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Marisol Guzman"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."
— Greg Reed
