ADU Company in Orange, CA

Kitchen remodeling in Orange usually means working inside a 1920s Craftsman bungalow or a 1950s ranch with dimensions that don’t match modern cabinet depths, and Harvest ADU Builders has served Orange since 2012, so we know those rooms well. Most Orange kitchens we see were designed for a different era: shorter counters, one or two outlets, and a stove alcove that limits ventilation. We plan around lath-and-plaster walls, older floor framing, and the hot Santa Ana afternoons that make ventilation and shade a real part of the design conversation. Call (866) 538-0916 when you’re ready to talk through your kitchen, and we’ll give you an honest read on what the space can do.

Why Orange Homes Are Different

Orange is not a clean-lot new-build city. The Old Towne Orange Historic District around the Plaza and Chapman University holds one of the largest concentrations of pre-1930 Craftsman and Victorian bungalows in Southern California, and that changes how a kitchen remodel is planned and permitted. Walls are rarely square after a century of settling. Floor joists are often true dimensional lumber, not modern engineered stock, which affects how we route plumbing and electrical. Many homes are on larger lots, but mature orange-era street trees and narrow driveways on the older parcels constrain delivery access and dumpster placement.

Climate matters too. Orange sits in the semi-arid Santa Ana foothill transition, so we design kitchens for hot, dry summers rather than heavy rain. Deep roof overhangs keep direct sun off south-facing windows, but inside the house, ventilation and good airflow matter more than most homeowners expect. A kitchen that traps heat from a range or oven becomes unpleasant by late afternoon. We plan hood venting and window and door placement around that reality. Permits in the historic district can also trigger design review, even for interior work if the house is a designated Mills Act property, so we build permitting time into the schedule from the start.

Our Main Orange Services

Two projects dominate the calls we get from Orange homeowners: building an ADU in the backyard, and remodeling a bathroom in the main house. Here’s how each one plays out in this city.

ADU Builders in Orange

Most ADU projects in Orange are detached backyard cottages tucked behind century-old houses, often near the alley-loaded garages that dot the older neighborhoods. Historic-district review can shape setbacks, massing, and even window proportions, so we approach the permitting phase as seriously as the framing. We build with prefab brands like Abodu and Dvele, and we also handle Tuff Shed conversions for homeowners who want a more budget-conscious path. From shell to move-in ready, we handle the entire structure, including the kitchen and bathroom, so you’re not coordinating a second contractor.

Bathroom Remodeling in Orange

Bathroom remodeling in Orange frequently means working within a 5-by-8 footprint that hasn’t changed since the house was built. Older bungalows and ranch homes often have cast-iron drain lines and limited subfloor access, so we plan for plumbing upgrades rather than hoping the existing pipes will hold. The Santa Ana heat means bathrooms benefit from proper exhaust ventilation, which many older Orange homes lack entirely. We handle the full scope: demo, plumbing, waterproofing, tile, fixtures, and finish work, all in-house. For details on bathrooms specifically in Orange, see Bathroom Remodeling in Orange.

Kitchen Remodeling in Orange

Kitchen remodeling in Orange comes down to this: the room was built for a way of living that no longer matches how the household actually cooks, stores food, and gathers. We work mostly in homes from 1900 through the 1960s, where cabinet boxes are shallow, counter space is limited to one short run, and ventilation is usually a recirculating hood that does almost nothing on a hot Santa Ana afternoon. The goal is a kitchen that works for the way you live now, without fighting the house’s original character. We handle the full scope, from design through plumbing, electrical, cabinetry, counters, and finish work, and our Kitchen Remodeling approach is built around matching the right layout to the right budget.

Full Gut and Reconfiguration

Signs you need it

The current layout can’t support two people cooking at once, the range sits against a wall with no landing space, and the sink faces a blank wall instead of the room.

What it costs in Orange

A full gut and reconfiguration in Orange typically runs $45,000 to $85,000, depending on whether we’re moving plumbing and electrical or keeping the wet wall in place.

How we do it

We demo to the studs, reframe as needed, relocate plumbing and electrical, then build back with new drywall, cabinetry, counters, flooring, and a properly vented hood.

Cabinet Refacing and Countertop Replacement

Signs you need it

The cabinet boxes are solid but the faces are worn, dated, or the wrong color, and the counters are chipped, stained, or too low for comfortable prep work.

What it costs in Orange

Refacing and new counters in Orange generally fall between $12,000 and $28,000, with solid surface and quartz landing on the higher end of that range.

How we do it

We remove the old doors and drawer fronts, apply new veneer or paint to the boxes, install new doors and hardware, and set new countertops over the existing cabinet run.

What Kitchen Remodeling Costs in Orange

Item Typical range in Orange
Full gut and reconfiguration $45,000 – $85,000
Cabinet refacing and countertops $12,000 – $28,000
Minor update (paint, hardware, lighting, backsplash) $6,000 – $15,000

Historic-district design review and older framing that needs structural correction are the two biggest price drivers in Orange. We write fixed, line-item quotes before work starts, so the number you approve is the number you pay.

How long does a kitchen remodel take in Orange?

A full kitchen remodel in Orange typically takes 6 to 10 weeks, depending on permit review in the historic district and what we find inside the walls once demo starts. We give you a written schedule before work begins.

Will a kitchen remodel in Old Towne require historic review?

Interior kitchen work usually does not trigger historic review unless the house is a designated Mills Act property, and even then, interior changes are generally treated more flexibly than exterior alterations. Call (866) 538-0916 and we’ll help you check your property’s status.

What Orange Customers Say

★★★★★ 4.8 from 4+ reviews

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

— Kristen Fletcher

"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."

— Vikram Sharma

"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."

— Heather Rhodes
