ADU Company in La Habra, CA

Kitchen remodeling in La Habra usually means working inside a 1950s or 1960s ranch home where the original footprint was built for a different era of cooking, storage, and family traffic. We remodel kitchens in houses from 90631 to 90633, and the job almost always involves upgrading the electrical panel, reworking plumbing that’s been in the slab for sixty years, and designing around the same hot, dry summers that push homeowners toward better ventilation and cooling. If you’re planning an ADU and a kitchen remodel at the same time, call (866) 251-7857 and we’ll map out both scopes before anyone swings a hammer.

Why La Habra Homes Are Different

La Habra is a built-out city. Most of the housing stock went in between the 1950s and 1970s, which means single-story ranch and traditional stucco homes on lots that are flat, deep, and often ringed by block walls. That layout is great for ADU placement. It also means the work comes with a specific set of conditions: 100-amp or smaller electrical panels that need upgrading before you add a second unit or a modern kitchen, clay sewer laterals that can be original, and mature citrus trees that have been growing since the Eisenhower administration. In the neighborhoods near historic downtown and along Whittier Boulevard, a lot of properties back onto alleys or have detached garages already set back from the street. That’s an ADU contractor’s best-case scenario because the unit can go up without eating the driveway or the front yard. The climate matters too. La Habra summers are hot and dry, and Santa Ana winds push through in the fall. Insulation, window placement, and cooling design aren’t afterthoughts here; they’re the difference between a comfortable unit and one that runs the AC constantly from June through October. The mild winters do make foundation and heating decisions simpler than in colder inland cities, which helps keep costs down on the build side.

Our Main La Habra Services

Most La Habra homeowners call us about two things: building an ADU in the back half of their lot, or remodeling a bathroom in a house that hasn’t been touched since the original build. Here’s what each job looks like here.

ADU Builders in La Habra

La Habra’s ADU market is defined by converting the deep, flat backyards of mid-century single-story tracts into second units under California’s streamlined ADU laws. Most of what we do here is garage conversions and backyard cottages, often on lots where a mature orange tree and a block wall shape the buildable area. Detached two-car garages from the 1960s are prime candidates, especially where the house has alley access. We work across the full spectrum: factory-built modular units from Mighty Buildings and Boxabl, design-forward prefab from Abodu and Cover, and conventional site-built construction when the lot calls for it. Read the full breakdown at ADU Builders in La Habra.

Bathroom Remodeling in La Habra

Bathrooms in La Habra ranch homes tend to be small, with original tile, cast-iron plumbing, and ventilation that was barely adequate in 1965. We remodel them with an eye toward the same homes’ future ADU use: better waterproofing, modern fixtures, and layouts that work for aging-in-place family members or tenants. The scope often includes moving a wall to steal space from an adjacent closet, replacing the shower pan, and updating the exhaust fan so humidity doesn’t sit in the walls.

Kitchen Remodeling in La Habra

Kitchen remodeling in La Habra means working within the footprint of a 1950s or 1960s ranch kitchen: original galley layouts, limited counter space, and cabinets that have been painted over three times. The heat is a real factor too. A kitchen that can’t vent properly makes the whole house harder to cool from July through September, and when the Santa Anas blow through, dust finds every unsealed gap. Our team handles the full scope, from panel upgrades and slab plumbing work to cabinet layout, ventilation, and finish carpentry. Foundry also carries this work beyond the ADU itself through our Kitchen Remodeling service line, so the same crew finishing your unit can build out the kitchen inside it.

Galley Kitchen Expansion

Signs you need it

You can’t open the oven and the dishwasher at the same time, or two people can’t work in the kitchen without trading places.

What it costs in La Habra

Expanding a galley kitchen in La Habra typically runs $45,000 to $75,000 depending on whether you’re removing a load-bearing wall and how much plumbing relocating is involved.

How we do it

We assess the load path, work with our structural engineer on the beam or header, relocate plumbing and electrical, then rebuild the kitchen with the new footprint and ventilation.

Full Kitchen Renovation

Signs you need it

Cabinet boxes are sagging or water-damaged, the layout fights the way you actually cook, and the flooring and lighting are original to the home.

What it costs in La Habra

A full kitchen renovation in La Habra runs $60,000 to $95,000, with the higher end covering custom cabinetry, stone counters, and panel upgrades.

How we do it

We demo to the studs, upgrade the electrical and plumbing, insulate and drywall, install new cabinets and counters, then handle flooring, lighting, and appliance placement.

Kitchen Remodel With Panel Upgrade

Signs you need it

The home still has a 100-amp or smaller panel, or the kitchen remodel adds circuits, an electric range, or an ADU subpanel to the same service.

What it costs in La Habra

A panel upgrade paired with a kitchen remodel in La Habra adds $4,000 to $8,500 to the project, depending on the service size and whether the main line needs replacement.

How we do it

We pull the permit, coordinate with Southern California Edison on the service drop, install the new panel and grounding, then route the new kitchen circuits and any ADU subpanel.

Will the price change once work starts?

What La Habra Customers Say

★★★★★ 4.8 from 4+ reviews

"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

"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."

— Marisol Delgado
