ADU Company in Brea, CA
Kitchen remodeling in Brea usually means working inside a 1960s or 70s ranch where the original layout still has a wall between the kitchen and the living room. We open those spaces, replace the single-panel electrical service that can’t handle modern appliances, and rebuild around the way Brea families actually use their kitchens today. Home Base ADU Builders has served Brea since 2016, and we’re the only contractor most of our clients need from foundation to finished kitchen, including ADU construction and bathroom work. Call (866) 403-9834 for a free estimate.
Why Brea Homes Are Different
Brea’s housing stock is post-war and 1960s-70s tract housing, mostly single-story stucco-on-wood-frame ranches and smaller two-story plans. Lots run 6,000 to 8,000 square feet, which is generous by Orange County standards, and that’s why detached ADUs and garage conversions dominate here. But the older stock also means converted garages often hit the original slab, a single-panel electrical service, and plumbing that has to be brought up to current code before any finished space can pass inspection.
The other thing that shapes every Brea job is the climate. The city sits in the inland north-county foothills just below Carbon Canyon, so summers run meaningfully hotter than coastal Orange County. Santa Ana wind events bring dry heat and fire-weather exposure, especially toward the canyon-adjacent edge near Brea Olinda. Detached ADUs in Brea want real insulation, shaded south and west walls, and Class A roofing with ember-resistant detailing. Those aren’t upgrades we try to sell; they’re code-informed decisions for this specific location.
Our Main Brea Services
Brea homeowners call us about two things more than anything else: building an ADU behind a ranch house on the flat grid near downtown Brea Boulevard, and remodeling bathrooms in homes where the original 1960s tile is still doing its job but the plumbing behind it is not.
ADU Builders in Brea
Brea adopted local ADU ordinances early and permissively, with state-law-aligned standards for detached units, conversions, and junior ADUs. Most of our Brea ADU work is garage conversions or rear-lot detached units behind 1960s ranches, where the recurring friction is lot coverage and rear setback rather than the unit itself. Site-plan review is where these jobs live or die, and we handle that end to end. We match you to the right ADU, not the one we have in stock. ADU Builders in Brea covers our full process, from permit submittal through final inspection.
Bathroom Remodeling in Brea
Brea bathrooms from the 1960s and 70s tend to hide cast-iron drain lines and galvanized supply piping inside walls that have never been opened. A cosmetic refresh turns into a plumbing replacement more often than homeowners expect, and we plan for that from the first walkthrough. We also handle the layout questions that come up constantly in smaller Brea ranches: whether to steal space from a closet, how to add a second sink without moving the toilet stack, and how to waterproof properly for a hillside-adjacent home. Bathroom Remodeling in Brea has the full scope.

Kitchen Remodeling in Brea
Kitchen remodeling in Brea comes down to two realities. The first is the housing era: most kitchens here were built in the 1960s and 70s, with closed-off layouts, original electrical panels that cannot support a modern appliance load, and plumbing that predates current code. The second is the climate: Brea’s inland heat means ventilation and cooling matter more here than they do in coastal kitchens, and we plan for that in every layout. We offer the full Kitchen Remodeling scope, from a simple cabinet and counter refresh to a full down-to-the-studs rebuild.
Cabinet and Countertop Refresh
Signs you need it
Your cabinets are structurally sound but the doors are delaminating, the hinges are failing, or the layout just fights you every time you cook.
What it costs in Brea
A cabinet refacing or replacement plus new countertops in Brea typically runs $12,000 to $35,000 depending on cabinet count and material.
How we do it
We remove the old doors and counters, assess the cabinet boxes, install new doors, drawers, and hardware, then template and set the new countertops, usually within two to three weeks.
Full Kitchen Gut and Rebuild
Signs you need it
The layout is closed off from the living space, the electrical panel can’t support current appliances, or the plumbing and subfloor need real repair, not a patch.
What it costs in Brea
A full gut kitchen remodel in Brea typically falls between $45,000 and $90,000, driven by the electrical upgrade, plumbing reroute, and cabinetry level.
How we do it
We demo to the studs, upgrade the electrical service and plumbing to current code, reframe for the new layout, then install insulation, drywall, flooring, cabinets, counters, and fixtures as one continuous job.
What Kitchen Remodeling Costs in Brea
| Item | Typical range in Brea |
|---|---|
| Cabinet refacing or replacement with new counters | $12,000 – $35,000 |
| Full kitchen gut and rebuild | $45,000 – $90,000 |
| Electrical service upgrade (panel and wiring) | $3,500 – $6,500 |
What pushes cost up in Brea is usually the age of the home. When we open a 1965 ranch wall and find aluminum wiring or a corroded cast-iron drain line, the scope changes. We give you a written line-item quote before work starts, and we do not change the price once the job is underway unless you change the scope.
How long does a kitchen remodel take in Brea?
Most Brea kitchen remodels run four to eight weeks depending on whether we’re moving plumbing or walls. A cabinet and counter refresh finishes faster, usually two to three weeks. Call (866) 403-9834 for a schedule based on your specific kitchen.
Will the price change once work starts?
No. We quote a fixed price from a line-item scope, and we honor that number unless you add work. Hidden conditions like old wiring get discussed with you before we proceed, never billed as a surprise. Estimates are free.
Brands We Service in Brea
Home Base ADU Builders works hands-on with Plant Prefab, Tuff Shed, Abodu, and the rest of our roster, and we use James Hardie fiber-cement exteriors on Brea ADUs because they hold up to the inland heat and Santa Ana exposure better than vinyl or wood siding. See our brands for the full comparison, and we’ll help you match the right one to your Brea lot.

We respond to Brea estimate requests within one business day and typically schedule the walkthrough within the same week. Our office is in Fountain Valley, so Brea is a short drive. Call (866) 403-9834 to set a time.
Yes. Brea requires permits for ADUs, kitchen remodels that touch electrical or plumbing, and structural changes. We pull all permits, schedule the inspections, and handle corrections if the city flags anything. You do not need to deal with Brea’s building department directly.
If your Brea neighborhood has an HOA, we prepare the architectural submittal package they need, including site plans, elevations, and material specs. HOAs in Brea cannot block a legal ADU under state law, but they can regulate aesthetics, so we handle that conversation for you.

What Brea Customers Say
"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Luis Garcia"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."
— Robert Hayes"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Colleen Pruitt
