ADU Company in Orange, CA
Kitchen remodeling in Orange, CA usually runs $28,000 to $65,000 for a full ADU kitchen, and the job here is different from most cities because so many of the homes we work in were built before 1960. Old Towne bungalows near the Plaza have small footprints, plaster walls, and plumbing stacks that were never designed for a second dwelling unit’s kitchen load. Foundry ADU Builders has served Orange since 2018, and we spend a lot of time making 1950s galley kitchens and carriage-house conversions work as real, code-compliant cooking spaces. Call (866) 251-7857 for a free estimate.
Why Orange Homes Are Different
Orange splits into two very different housing stocks, and the ADU kitchen work follows that split. The Old Towne core around the Plaza is full of pre-1920s Victorians, Craftsman bungalows, and Spanish Colonial Revival cottages, many of them under a historic preservation overlay. That review process can dictate rooflines, window proportions, and even setback placements on anything visible from the street, which means an ADU kitchen often has to fit inside a converted rear garage rather than a new footprint. Detached garages at the rear lot line are common in those downtown blocks, so the kitchen frequently lands in a structure that started as a carriage house with no plumbing, no insulation, and a slab that was never meant to carry an appliance circuit.
Out toward east Orange and the 92867 and 92868 corridors, the picture changes. Those are 1950s through 1970s single-story tract homes on generous lots, where rear-yard ADUs with attached or separate kitchens are far more straightforward. The climate works in our favor: warm inland summers and mild winters mean cooling is a bigger concern than heating, and roof drainage matters more than freeze protection. We spec shaded patio access and efficient mini-split systems on almost every Orange ADU kitchen we build.
Our Main Orange Services
Most Orange homeowners reach out to us about two things: building the ADU itself, and finishing the bathroom that makes it functional as a rental or a place for family. Both require the same permits, the same historic review awareness near the Plaza, and the same single-contractor follow-through.
ADU Builders in Orange
We handle the full ADU build in Orange, from the foundation through the shell to the finished interior. On Old Towne lots, that often means converting a rear detached garage into living space that clears the historic design review board, while east Orange parcels usually allow for a brand-new detached unit with a clean setback. We work across prefab, modular, and site-built methods, so the build path matches your lot and review constraints rather than forcing one system onto the property. ADU Builders in Orange covers the full construction scope.
Bathroom Remodeling in Orange
A rental ADU in Orange needs a bathroom that can handle repeated daily use by tenants, while a multigenerational unit often needs grab-bar blocking and zero-threshold shower pans. We run new drain lines on downtown garage conversions and manage the venting and waterproofing details that Orange’s winter rains make non-negotiable on a detached structure. The same crew that framed the ADU handles the bathroom finish work, so there is no handoff between contractors. Bathroom Remodeling in Orange details the range of bathroom work we perform.

Kitchen Remodeling in Orange
Kitchen remodeling in Orange is really two jobs. On an Old Towne ADU conversion, we are usually fitting a full kitchen into a former rear garage or a carriage house footprint, working around plaster, tight side-yard setbacks, and a historic review that may restrict exterior changes. On an east Orange rear-yard unit, the kitchen goes into new construction, and the priorities shift to layout efficiency, appliance selection, and making the space feel larger than it is. Foundry ADU Builders performs Kitchen Remodeling that matches the build method you chose for the ADU, because a prefab kitchen and a site-built kitchen are not the same job.
ADU Kitchen Buildout
Signs you need it
The ADU shell is up but the interior is bare, and you need a working kitchen before the unit can be rented or occupied.
What it costs in Orange
An ADU kitchen buildout in Orange typically runs $28,000 to $65,000 depending on appliance tier, cabinet grade, and whether the space was originally plumbed.
How we do it
We rough in the plumbing and electrical, pass the Orange county inspection, then install cabinetry, counters, appliances, and finish the space to occupancy.
Galley Kitchen Conversion
Signs you need it
The existing 1950s galley kitchen is too narrow, poorly lit, or fails to meet current code for a second dwelling unit’s cooking area.
What it costs in Orange
A galley kitchen conversion in Orange ranges from $24,000 to $48,000, with the lower end covering a like-for-like refresh and the upper end including full reconfiguration.
How we do it
We open the walls to assess the plumbing stack and framing, then rework the layout to fit modern appliances and ventilation within the original footprint.

How long does an ADU kitchen take in Orange?
A full ADU kitchen in Orange takes four to eight weeks once the shell is closed in and inspections are scheduled. Historic review near the Plaza can add a few weeks to the front end even before construction starts. Call (866) 251-7857 for a timeline tied to your specific lot.
Will the price change once work starts?
No. We write line-item quotes, and the price is fixed unless you alter the scope. Old Towne inspections can occasionally require additional strapping or drain upgrades, and we flag those as change orders before any work happens, never after.

What pushes price up in Orange is almost always the historic review process near the Plaza: matching rooflines, window styles, and setback requirements on a 1920s Craftsman-adjacent lot can add design and materials costs that a standard east Orange tract lot never sees. Our quotes are line-item and fixed before we pull the permit, so you know the number going in.

What Orange Customers Say
"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Shannon Gallagher"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Marisol Delgado"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Brandon Wong
