ADU Company in Brea, CA
Foundry ADU Builders handles kitchen remodeling in Brea with an ADU-first mindset, which matters more than you’d think on mid-century ranch lots. Most Brea kitchens sit inside homes built from the 1950s through the 1970s, so the framing, electrical, and plumbing all predate modern code. That means a kitchen remodel here isn’t just swapping cabinets. It’s upgrading circuits, reworking drain lines, and often removing a load-bearing wall to open the floor plan. Call (866) 251-7857 for a free estimate.
Why Brea Homes Are Different
Brea’s housing stock runs heavy on single-family ranch homes from the 1950s through the 1970s, particularly in the older tracts south of Lambert Road and around the Brea Mall area. These homes have real working kitchens, but they were built when a 60-amp panel and two countertop outlets were considered plenty. We run into aluminum branch wiring more often here than in newer cities, and the original cast-iron drain lines under slab are usually at the end of their useful life by the time a kitchen remodel happens. The hot, dry summers also mean any kitchen remodel should address ventilation and cooling loads. A 1950s kitchen with no proper range hood and a single window on the west wall will cook the rest of the house from June through September. On top of that, Brea’s hillside neighborhoods bring slope and grading considerations that flat-lot cities like Fullerton or La Habra don’t deal with. We plan for those realities up front rather than discovering them mid-project.
Our Main Brea Services
Brea homeowners usually reach out to us about one of two things: building an ADU from the ground up, or bringing an older bathroom up to something their family can actually live with. Here’s how each one works in Brea.
ADU Builders in Brea
Brea has made itself one of North Orange County’s most ADU-friendly cities, and the older ranch lots south of Lambert Road are well suited for detached units and garage conversions. We build across the full spectrum: factory-built modular units from brands like Boxabl and Mighty Buildings, design-forward prefab from Abodu and Cover, and traditional site-built construction. Hillside properties with protected oak trees add grading and root-zone considerations that we handle during the permitting phase. Foundry ADU Builders has served Brea since 2018. See ADU Builders in Brea for the full scope of work.
Bathroom Remodeling in Brea
Bathrooms in Brea’s 1950s and 1960s ranches tend to be small, and many still have the original tile set in a thick mortar bed. The work usually involves gutting to the studs, replacing the subfloor, and moving walls when the lot allows it. We carry the same crew from ADU construction through the bathroom interior, which keeps the schedule and the budget predictable. Find details at Bathroom Remodeling in Brea.

Kitchen Remodeling in Brea
Kitchen remodeling in Brea comes down to fixing what 60-year-old construction left behind while making the room work for how people actually cook now. Homes in the older tracts south of Lambert Road and near the Brea Mall area often have galley kitchens with a single circuit for all the countertop outlets. You can’t run a microwave and a toaster at the same time without tripping a breaker, and the original cast-iron drain lines usually need replacement while the walls are open. We handle the full Kitchen Remodeling scope: layout, electrical, plumbing, cabinets, counters, and finish work, without passing you off to a second contractor.
Full Gut and Reconfiguration
Signs you need it
Your Brea kitchen still has the original 1950s or 1960s footprint, the cabinet boxes are particleboard that’s swelling at the base, and the room can’t fit two people without shoulder-checking each other.
What it costs in Brea
A full gut and reconfiguration in Brea typically runs $500 to $1,200 per square foot, with most mid-century ranches coming in at $45,000 to $85,000 depending on how many walls move and how much electrical has to be rebuilt.
How we do it
We strip the room to framing, reframe load-bearing openings with proper headers, run new circuits back to the panel, replace the cast-iron drain lines, then rebuild the space with new cabinets, counters, flooring, and appliances.
Cabinet and Countertop Replacement
Signs you need it
Your cabinets are structurally sound but the doors are delaminating, the hinges are worn out, and the laminate counters are chipped or burned in several places.
What it costs in Brea
Cabinets in Brea run $150 to $500 per linear foot installed, countertops run $50 to $150 per square foot, and a mid-sized kitchen with new cabinets and counters typically lands between $20,000 and $40,000.
How we do it
We remove the old cabinets and counters, check the wall framing for plumb and level, install the new cabinet boxes and face frames, then template and install the countertop material you’ve selected.
What Kitchen Remodeling Costs in Brea
| Item | Typical range in Brea |
|---|---|
| Full kitchen gut and remodel | $45,000 – $85,000 |
| Cabinet replacement (per linear foot) | $150 – $500 |
| Countertop replacement (per sq ft) | $50 – $150 |
How long does a kitchen remodel take in Brea?
Most full Brea kitchen remodels take 6 to 10 weeks from demo to final walkthrough. The timeline stretches when we’re replacing cast-iron drain lines, rewiring entire circuits, or waiting on city inspection slots. Call (866) 251-7857 to get a realistic schedule for your kitchen.
Will the price change once the kitchen work starts?
No, not from us. We price the job up front with a written line-item proposal, and the number doesn’t move unless you change the scope. If we find termite damage or failing drain lines inside a wall, we flag it, show you photos, and give you a change order before touching it. Call (866) 251-7857 for an exact quote.
Brands We Service in Brea
We work across the ABODU lineup, from Tuff Shed conversions to design-forward Abodu and Cover prefab units, and we use James Hardie fiber cement for exterior cladding where fire resistance and durability matter. Parts and materials for these brands are available through our local suppliers without the long lead times that stall other Brea projects.

In Brea, prices push higher when we’re working on a hillside lot that needs grading and retaining, when protected oak trees require root-zone surveys and foundation redesign, or when a 1950s panel has to be swapped for a 200-amp service before the new circuits go in. The price we quote is the price you pay because we write a fixed line-item proposal before any work starts, not a ballpark that moves later.

We work throughout Brea, from the mid-century tracts south of Lambert Road to the planned communities near the Brea Mall and the hillside streets where grading and tree protection shape every foundation decision.

FAQs About ADU Company in Brea
We can usually schedule a Brea estimate within the same week you call. Hillside lots with protected oaks or lots that need grading sometimes take an extra site visit before we can give you a fixed number, but the initial walkthrough is free. Call (866) 251-7857 to get on the schedule.
Yes. We pull permits with the City of Brea and coordinate any HOA or CC&R review, which matters most in the newer planned communities where architectural review boards can slow things down. We submit the drawings, respond to plan-check comments, and schedule inspections until the job is signed off. Call (866) 251-7857 with your address and we’ll tell you what applies.
Yes, and that’s actually how we prefer to work. Running one crew on the ADU shell while a second team handles the kitchen means the project finishes sooner and the dumpster, permits, and site logistics only have to be coordinated once. Call (866) 251-7857 and we’ll walk you through a combined schedule.

What Brea Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Brandon Wong"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."
— Holly Reed"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Shannon Gallagher
