ADU Company in Brea, CA

Kitchen remodeling in Brea means working with homes built between the 1950s and 1970s, where original layouts were designed for a different era of cooking and gathering. We plan around the city’s mix of flat tract lots and hillside properties, because a 92821 ranch home on a slab and a 92823 hillside build on a raised foundation have completely different constraints. Our team handles the full scope from demolition to finish, and we’re the same contractor Brea homeowners call for ADUs and bathroom remodels. Call (877) 265-7231 to schedule a free estimate.

Why Brea Homes Are Different

Brea’s housing stock splits along a clear line, and that line changes how we approach every kitchen. The older 92821 neighborhoods off Central Avenue and Brea Boulevard are full of 1950s and 1960s ranch homes with compact galley kitchens, often tucked between a load-bearing wall and the garage. Those walls are frequently structural, so opening the kitchen into the living room requires a beam specification before we touch a single cabinet. The 92822 and 92823 areas move into newer construction, but the hillside lots in 92823 bring their own friction, including engineered plans for any load change and careful attention to drainage when we extend a kitchen toward the rear yard.

Climate matters too. Brea’s Santa Ana winds and intense summer sun mean we spec finishes and ventilation that hold up under heat and dust, and range hoods sized for real cooking, not just code minimums. The occasional winter rain is less of a concern inside the kitchen, but any exterior wall we open needs proper flashing and moisture barrier work, especially on the windward side of a hillside home. These are the conditions that make a Brea kitchen remodel different from one in a coastal city with marine air and a newer housing stock.

Our Main Brea Services

Most Brea homeowners call us for one of two reasons: they want to add an ADU in the backyard, or they want to upgrade a bathroom that hasn’t changed since the original build. Both are projects we handle regularly across all three Brea ZIP codes.

ADU Builders in Brea

Adding an ADU in Brea is a different exercise depending on which side of the city you live on. In the flat 92821 tracts, detached garages on alleys are prime conversion candidates, but the city’s setback and lot-coverage rules often require a variance. In 92823, the sloped lots make grading, retaining walls, and delivery access the dominant cost drivers. We work across prefab and site-built methods, matching each lot to the system that actually fits. ADU Builders in Brea covers the full breakdown of what works where in this city.

Bathroom Remodeling in Brea

Bathrooms in Brea’s older tract homes are small, often original to the 1960s, and built on slab foundations that make moving drain lines a real cost consideration. Hillside bathrooms in 92823 have different issues, including floor leveling and waterproofing on homes that shift with the terrain. We handle both conditions, and we coordinate the work with any kitchen or ADU project so sequencing doesn’t stall progress. Bathroom Remodeling in Brea has the local cost details and timelines.

Kitchen Remodeling in Brea

Kitchen remodeling in Brea comes down to two recurring jobs: opening up the closed-off galley kitchens in the 1950s through 1970s tract homes of 92821, and modernizing the newer but dated kitchens in 92822 and 92823. The older homes almost always have a load-bearing wall between the kitchen and living area, which means a beam and structural plans before the space can be opened. The newer homes are less likely to need structural work, but they often carry builder-grade cabinets and appliances that have reached the end of their useful life. We handle both types, and we plan each project around the home’s era and foundation type rather than applying a generic layout. Our full Kitchen Remodeling service covers the complete process from layout to finish.

Galley Kitchen Opening

Signs you need it

The kitchen is closed off from the dining or living area, and you can’t be in the same room as guests or family while cooking.

What it costs in Brea

Opening a galley kitchen in Brea typically runs $45,000 to $85,000 depending on whether the wall is load-bearing and what finish level you choose.

How we do it

We assess the wall for load, spec a beam with an engineer, remove the wall and any soffits, then rebuild the new opening with trim, flooring, and ceiling work to match.

Full Kitchen Renovation

Signs you need it

Cabinets are delaminating, the layout doesn’t support how you cook, or the appliances and plumbing are original to the home.

What it costs in Brea

A full kitchen renovation in Brea generally lands between $60,000 and $120,000, with hillside homes in 92823 trending toward the upper end due to access and structural variables.

How we do it

We demo the existing kitchen, relocate plumbing and electrical as needed, install new cabinets and counters, tile the backsplash, and finish with appliances and lighting.

Cabinet and Counter Replacement

Signs you need it

The cabinet boxes are sound but the doors, faces, and counters are worn, chipped, or simply the wrong material for how the kitchen is used.

What it costs in Brea

Cabinet and counter replacement in Brea typically runs $18,000 to $45,000 depending on linear footage and material, with slab lots in 92821 usually at the lower end of that range.

How we do it

We measure the existing layout, order the new doors, faces, and counters, remove the old surfaces, install the new cabinets and counters, and reconnect the sink and appliances.

Galley kitchen opening $45,000 to $85,000
Full kitchen renovation $60,000 to $120,000
Cabinet and counter replacement $18,000 to $45,000

How long does a kitchen remodel take in Brea?

Most Brea kitchen remodels run 4 to 8 weeks, with structural openings on the older tract homes taking longer because of beam fabrication and inspection scheduling at the city.

Do you pull permits for kitchen work in Brea?

Yes. We pull all required permits with the City of Brea before work begins, and we handle the inspection scheduling and any corrections directly with the building department. Call (877) 265-7231 for details.

Brands We Service in Brea

We spec the brands that hold up in Brea’s heat and wind. James Hardie fiber-cement exteriors are our default for any ADU or addition wall, and we’ve built with Plant Prefab, Abodu, and Tuff Shed systems across the city’s flat and hillside lots. Our brands page explains what each system does best.

What pushes a Brea price up is the same thing that makes the city interesting: the slope. Hillside 92823 jobs carry grading, retaining wall, and crane or delivery access costs that flat 92821 lots never see. We give every Brea homeowner a written line-item quote before work starts, and that number doesn’t change unless you change the scope.

What Brea Customers Say

★★★★★ 5.0 from 4+ reviews

— Alicia Ingram

"He gave us a realistic rental number for the finished unit rather than the optimistic one, and it's renting for about what he said."

— Danika Prince

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