ADU Company in Irvine, CA

Kitchen remodeling in Irvine runs between $38,000 and $95,000 for a full gut renovation in a typical master-planned Village home, with most projects landing around $55,000 to $70,000 depending on layout changes and finish level. We’re Classic ADU Builders, and we’ve spent years working inside Irvine’s tract-built housing stock, so we understand what it takes to reconfigure a 1970s Woodbridge kitchen or a 1990s Westpark cookspace without fighting the original framing. Call (877) 265-5587 for a free estimate, and we’ll walk your kitchen with you before you commit to anything.

Why Irvine Homes Are Different

Irvine’s housing is overwhelmingly Irvine Company master-planned construction from the late 1960s through the 2010s. That means stucco-over-wood-frame walls, consistent floor systems, and floor plans that repeat across entire tracts. When we open a kitchen wall in University Park, we already know what we’ll find behind it, because we’ve worked the same plan in Woodbridge and Northwood. The Villages were built fast and tight, which is good news for structural predictability but tricky when you want to remove a load-bearing wall or move plumbing more than a few feet. Older Village homes from the 1970s and 1980s often have kitchens boxed into corners with soffits concealing ductwork, while 1990s and 2000s builds opened up sightlines but used slab foundations that make drain relocation expensive. The dry, near-coastal climate means kitchen ventilation and cooling are bigger daily concerns than moisture management, though marine-layer mornings still bring humidity against exterior walls. And because nearly every detached Irvine lot sits inside a Village HOA with recorded CC&Rs, any kitchen work that touches an exterior wall, a window opening, or a gas line may trigger architectural review alongside the City of Irvine permit.

Our Main Irvine Services

Irvine homeowners most often call us for two things: building an ADU and remodeling a bathroom. Both end up in our kitchen conversations because integrated interior finish work is where a house actually becomes livable.

ADU Builders in Irvine

Adding a detached ADU in Irvine means navigating the City’s permit process and your Village HOA’s architectural review at the same time. We pull CC&Rs before we draw anything, because rear-yard setbacks, wall height, and roof material restrictions vary from Woodbridge to Portola Springs. We’ve built with Abodu, Cover, and Dvele systems on Irvine lots, and we also do custom site-built units where the yard calls for something specific. James Hardie fiber cement is our default exterior on custom builds because it holds up to Orange County sun without warping. ADU Builders in Irvine get a contractor who already knows which manufacturers clear Irvine’s planning desk fastest.

Bathroom Remodeling in Irvine

Bathroom work in Irvine’s tract homes usually means working inside a 5-by-8 or 5-by-10 footprint the original builder set decades ago. We move vanities, re-pipe showers, and re-tile floors without disturbing the slab when we can avoid it. Because most Village bathrooms share a wet wall with the kitchen or a second bath, a remodel often reveals supply lines that should have been replaced years ago. We handle that in-house rather than handing you off to a second contractor. Bathroom Remodeling in Irvine means full interior finish capability, not just a shell contractor.

Kitchen Remodeling in Irvine

Kitchen remodeling in Irvine is about updating a workspace that was designed for a different decade: boxed-in galley kitchens in Woodbridge, closed-off cookspaces in Northwood, and 2000s islands that don’t function for how people cook now. The dry heat and marine-layer humidity mean we focus on ventilation, window placement, and finishes that won’t warp when the Santa Ana winds roll through. As a full-service contractor, we handle everything from framing and drywall to cabinets, countertops, and appliance rough-in, which means one crew carries your kitchen from demo to finished space. If you’re also weighing an ADU or a bathroom remodel, our Kitchen Remodeling work dovetails with both.

Full Gut Renovation

Signs you need it

Your kitchen layout fights you every day, the cabinets are original to a 1980s build, and the plumbing or electrical has never been updated.

What it costs in Irvine

A full gut renovation in Irvine typically runs $55,000 to $95,000 depending on whether you move walls, relocate the sink, or upgrade the panel.

How we do it

We demo to studs, address any framing or wiring surprises from the original tract build, then rebuild with new drywall, flooring, cabinetry, counters, and appliance rough-in so the space is fully finished before we hand it back.

Layout Reconfiguration

Signs you need it

The existing footprint works but the flow doesn’t: the island blocks the fridge, the sink faces a wall, or the kitchen is cut off from the family room.

What it costs in Irvine

A layout reconfiguration in Irvine lands between $38,000 and $70,000 when it involves opening a wall or relocating plumbing, with slab-on-grade homes at the higher end.

How we do it

We identify which walls are load-bearing from the original Village plan, design a revision that respects the structural grid, and move only what’s necessary to open the space without a full gut.

What Kitchen Remodeling Costs in Irvine

Item Typical range in Irvine
Full gut renovation $55,000 – $95,000
Layout reconfiguration $38,000 – $70,000
Finish-only refresh (cabinets, counters, flooring) $26,000 – $48,000

How long does a kitchen remodel take in Irvine?

Most Irvine kitchen remodels run 6 to 10 weeks from demo to final walkthrough, assuming no HOA-required exterior changes or slab plumbing surprises. Large layout changes or custom cabinetry can push toward 12 weeks. Call (877) 265-5587 and we’ll give you a schedule tied to your specific scope, not a generic timeline.

Will the price change once work starts?

No, not unless you change the scope. We write fixed-price estimates after opening walls on older Irvine homes so we can see the framing before quoting. Call (877) 265-5587 for a line-item estimate that holds.

What Irvine 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."

— Marcy Miller

"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."

— Beatriz Morales

"The kitchenette layout he suggested made better use of the space than the one on our original sketch."

— Eric Tran
