ADU Company in Irvine, CA

Kitchen remodeling in Irvine means working inside homes built by the Irvine Company under village-specific design rules, where a 1980s Woodbridge kitchen and a 2015 Stonegate kitchen present entirely different plumbing, structural, and HOA approval paths. The warm, dry climate means our remodels prioritize cooling-conscious ventilation and glare-resistant finishes, not freeze-proofing. For kitchen work here, call Oakhall ADU Builders at (877) 588-6929. We’re ADU specialists first, which means we think about how your kitchen remodel might one day tie into a garage conversion or attached addition before we cut the first cabinet.

Why Irvine Homes Are Different

Irvine is a master-planned city built almost entirely by the Irvine Company under village-specific design guidelines and HOA architectural-review covenants. Every ADU or major remodel here has to clear two approvals: City of Irvine planning and zoning, including the state-mandated pre-approved ADU plan program the city adopted, and the village HOA’s architectural committee. That committee routinely imposes color, roof pitch, and setback conditions that go well beyond code. We’ve seen stucco colors pass in Woodbridge and get bounced in Turtle Rock. The dual-approval reality is sharper in Irvine than in neighboring Orange County cities because so much housing sits under active, design-conscious HOA governance.

The housing stock itself shapes the work. Older villages like Woodbridge, Turtle Rock, University Park, and Rancho San Joaquin are full of Mediterranean revival stucco homes with clay tile roofs from the 1970s through 1990s. Newer villages like Great Park, Stonegate, and Cypress Village pack three-story detached condos and motor-court homes onto tighter lots. That means ADUs here are almost always garage conversions, attached rear additions, or second-story-over-garage builds squeezed into small, HOA-regulated lots. A kitchen remodel in the same home has to respect those same village design rules, especially if it changes exterior wall openings or venting.

Our Main Irvine Services

Irvine homeowners call us most often about two things: building an ADU they can rent or use for family, and remodeling a bathroom inside that ADU or the main house. Each has its own Irvine-specific approval path.

ADU Builders in Irvine

Building an ADU in Irvine means designing a unit that clears both the city’s pre-approved plan program and your village HOA. We handle that from the first site visit, comparing garage conversions, attached additions, and second-story-over-garage builds against your lot’s actual constraints in villages like Woodbridge or Great Park. We’re brand-agnostic across Abodu, Dvele, Cover, and other prefab options, plus site-built custom units, so you get the right fit rather than the only option a single-brand dealer sells.

Bathroom Remodeling in Irvine

Bathroom remodels in Irvine’s older villages often mean dealing with original cast-iron plumbing and layouts built before dual-pane windows were standard. In newer villages, the issue is more often maximizing a compact footprint without triggering HOA review for venting or window changes. We run the whole job from demolition to tile, and because we also build ADUs, we can tie a bathroom remodel into a future garage conversion without redoing work. Details are on our Bathroom Remodeling in Irvine page.

Kitchen Remodeling in Irvine

Kitchen remodeling in Irvine usually means refreshing a 1980s or 1990s kitchen in an older village home, or reconfiguring a compact galley in a newer motor-court house. The dry, warm climate means we focus on ventilation that moves hot air out and glazing that cuts west-facing afternoon glare, not freeze protection. Because Oakhall is an ADU specialist, we also plan your kitchen so a future garage conversion or Kitchen Remodeling addition can share walls, plumbing, and permits cleanly.

Cabinet Replacement and Reconfiguration

Signs you need it

Doors that sag or no longer close, shelves bowing under normal dish loads, or a layout that forces you to walk around an island just to reach the refrigerator.

What it costs in Irvine

Cabinet replacement and reconfiguration in Irvine typically runs $12,000 to $30,000 depending on cabinet count, finish level, and whether we’re moving plumbing or electrical to support a new layout.

How we do it

We measure everything in the existing footprint, pull permits if walls or utilities move, manage HOA design review if exterior venting changes, then demo, install new cabinets, and reset counters and appliances.

Countertop and Backsplash Upgrade

Signs you need it

Chipped or scorched laminate, grout that won’t stay clean, or a dated tile backsplash dragging down an otherwise functional kitchen.

What it costs in Irvine

Countertop and backsplash upgrades in Irvine generally fall between $6,000 and $15,000 for typical kitchen sizes, with engineered stone and full-height backsplashes at the upper end.

How we do it

We template after cabinets are set, fabricate the stone or solid surface off-site, then install in a single day and seal everything against Irvine’s hard water and dry heat.

What Kitchen Remodeling Costs in Irvine

Item Typical range in Irvine
Full kitchen remodel (mid-range) $30,000 – $60,000
Cabinet replacement and reconfiguration $12,000 – $30,000
Countertop and backsplash upgrade $6,000 – $15,000

How long does a kitchen remodel take in Irvine?

Most Irvine kitchen remodels run four to eight weeks from demo to final inspection. HOA design review, when required for venting or window changes, adds one to three weeks up front. Call (877) 588-6929 for a timeline tied to your specific village.

Will the price change once work starts?

No. We write fixed line-item quotes after the walkthrough, and they don’t change unless you add scope. If we open a wall and find something unexpected, we show you photos and a written change order before touching it. Call (877) 588-6929 to schedule a free estimate.

Brands We Service in Irvine

We work across Plant Prefab, Tuff Shed, Abodu, and other major prefab brands, plus site-built custom units finished with James Hardie fiber cement. Because we’re not tied to one manufacturer, we can tell you exactly where each brand wins and where it doesn’t for your specific Irvine lot. Many structural and finish parts are available through local Orange County suppliers, which keeps lead times shorter than ordering from out of state. See our brands for the full comparison approach.

What Irvine Customers Say

★★★★★ 4.8 from 4+ reviews

"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."

— Lucia Rodriguez

"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."

— Riya Reddy

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

— Travis Norris
