ADU Company in Huntington Beach, CA

Kitchen remodeling in Huntington Beach comes with a specific set of conditions: 1950s and 1960s tract homes with original layouts, marine-layer humidity that warps cheap cabinet boxes, and post-war framing that rarely matches modern appliance dimensions. Foundry ADU Builders handles the full kitchen scope – from demo through finish carpentry – and we’re the same contractor Huntington Beach homeowners call when an ADU project includes a kitchen. Call us at (866) 251-7857 for a free estimate on your kitchen or ADU build.

Why Huntington Beach Homes Are Different

Huntington Beach’s housing stock splits into three distinct bands, and each one changes how we approach a kitchen or ADU interior. The 92646 and 92647 corridor is dominated by dense post-war tract homes, many built between 1955 and 1975 on 6,000-square-foot lots. These kitchens are tight, often 10×12 feet, with load-bearing walls that run through the middle of where homeowners want an island. The 92648 downtown and west-side pockets include older beach cottages and duplexes with even smaller footprints, settled foundations, and rooms that have been patched together through decades of remodels. The coastal influence matters too: salty onshore air corrodes standard cabinet hinges and drawer slides within a few years, so we specify stainless or coated hardware on every job near the sand. And because most of these post-war homes use 2×4 framing, running new electrical circuits and venting for range hoods requires opening more wall than a newer home would.

Our Main Huntington Beach Services

Huntington Beach homeowners contact us for two projects more than anything else: ADU construction and bathroom remodels that tie into those ADUs. Here’s what each involves locally.

The Coastal Commission’s jurisdiction changes the ADU conversation west of PCH. A second-story unit in the 92648 coastal zone with any view-corridor impact can stall in permit review for months, so we steer most Huntington Beach clients toward single-story detached units or garage conversions in the 92646/92647 corridor, where the post-war lots have enough depth for a rear-yard structure without triggering coastal overlay setbacks. ADU Builders in Huntington Beach work with us across prefab brands and stick-built methods, matched to your lot and permit path.

Bathroom Remodeling in Huntington Beach

Bathroom work in Huntington Beach frequently happens inside an ADU, where the space is limited and the plumbing path is already constrained by the main house’s sewer line. In 1950s tract homes, we routinely find cast-iron drain lines that need section replacement before any new fixture can be set, and in the coastal zone, every plumbing change gets extra coastal review. Bathroom Remodeling in Huntington Beach covers both standalone remodel work and ADU interior finishes.

Kitchen Remodeling in Huntington Beach

Huntington Beach kitchens from the post-war era were built for a different life: closed off, small, and wired for a few appliances. Our Kitchen Remodeling work focuses on opening the room without compromising the post-tension slab foundations common in the 92646/92647 tract homes, while specifying marine-rated finishes for homes near the ocean. The two jobs we do most in Huntington Beach are cabinet and countertop replacement and full kitchen reconfiguration.

Cabinet and Countertop Replacement

Signs you need it

Doors that no longer close flush, swollen particleboard frames from years of coastal humidity, or faces that delaminate at the edges.

What it costs in Huntington Beach

Cabinet and countertop replacement in Huntington Beach typically runs $18,000 to $40,000 depending on layout and material grade.

How we do it

We measure the existing footprint, order boxes and countertop slabs, demo the old units in a day, and install pre-assembled cabinets with ship-lap grade plywood boxes rated for humid coastal air.

Full Kitchen Reconfiguration

Signs you need it

The work triangle doesn’t exist, the kitchen can’t seat more than one person, or the room is walled off from the living space you use every day.

What it costs in Huntington Beach

Full kitchen reconfiguration in Huntington Beach usually falls between $30,000 and $65,000, with the upper end reflecting structural header installation and slab plumbing moves.

How we do it

We open the walls to confirm bearing points, frame any new opening with engineered headers, relocate plumbing and electrical, then rebuild with new cabinets, counters, and finish trim.

What Kitchen Remodeling Costs in Huntington Beach

Item Typical range in Huntington Beach
Cabinet and countertop replacement $18,000 – $40,000
Full kitchen reconfiguration $30,000 – $65,000
Appliance and plumbing rough-in update $3,500 – $8,000

Kitchens in the 92648 coastal zone cost more when the remodel triggers coastal review, which adds plan-check weeks and sometimes view-corridor mitigation. We give every Huntington Beach client a fixed written quote before work starts, and that price doesn’t change unless you change the scope.

How long does a kitchen remodel take in Huntington Beach?

Most Huntington Beach kitchen remodels take 6 to 10 weeks. Coastal-zone permits and custom cabinet lead times add the upper-end weeks. Call (866) 251-7857 to get a timeline for your specific scope.

Will you pull permits for a Huntington Beach kitchen remodel?

Yes. We pull all required Huntington Beach building permits and handle inspections. Coastal-zone projects get the additional Coastal Commission paperwork filed as part of the permit package. Call (866) 251-7857 for details on your lot’s specific permit path.

Brands We Service in Huntington Beach

Our brands page covers the full range, and our Brea yard keeps the most common trim, flashing, and panel profiles in stock.

What Huntington Beach Customers Say

★★★★★ 4.8 from 4+ reviews

"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

"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
