ADU Company in Irvine, CA

Kitchen remodeling in Irvine means working inside one of the most tightly master-planned cities in California, where 1960s through 2000s tract homes carry consistent floor plans but aging finishes, and where HOA design review can shape even interior-adjacent decisions like range hood venting or window changes. The warm, dry Mediterranean climate pushes homeowners toward ventilation, shade, and surfaces that hold up to constant sun exposure. Westminster ADU Builders has served Irvine since 2016, and we’ll walk you through the exact process, honest pricing, and the permits and approvals that actually apply here.

Why Irvine Homes Are Different

Irvine is a master-planned city built almost entirely by the Irvine Company, and that singular origin shapes nearly every remodeling job. The housing stock is overwhelmingly Spanish-revival stucco and tile-roof tract homes organized into villages like Woodbridge, Northwood, Turtle Rock, Westpark, and the newer Great Park neighborhoods. Those villages operate under CC&Rs that often outpace city code on visible exterior changes, which means a kitchen remodel that touches a window opening, vent termination, or any street-facing wall can trigger both a city permit and a separate HOA architectural review.

Lot sizes here were standardized block by block, so many homes share nearly identical footprints. That consistency helps us move faster on layout planning because we’ve seen the same floor plans repeat across Northwood and Westpark. But it also means kitchens in Irvine homes from the 1980s and 1990s were built to original tract specs: fluorescent soffit lighting, raised-panel oak cabinets, and no dedicated venting in some cases. Clay soils and engineered fill under many older villages can cause slab movement over decades, which shows up as hairline cracks in tile and counters. We account for that when we spec flooring and prep work. The same plan can pass Irvine’s building counter without issue and still stall in a village architectural committee, which is why we sequence those approvals early and keep documentation consistent.

Our Main Irvine Services

Homeowners in Irvine most often call Westminster ADU Builders for two projects: building an accessory dwelling unit on a tight village lot, or remodeling the bathroom in a home that hasn’t been touched since the 1980s or 1990s. Both pull in city requirements and HOA realities, and both benefit from a contractor who already knows Irvine’s specific approval layers.

ADU Builders in Irvine

ADUs in Irvine run through both the city’s ADU ordinance and, in most villages, an HOA architectural review that can restrict rooflines, height, and visibility from the street. Many detached ADUs here squeeze into compact rear yards on lots sized to the original tract plan, which is why garage conversions are common where lot coverage is already maxed out. ADU Builders in Irvine details the prefab and site-built paths, the brand options from Abodu, Cover, and Dvele, and the full build process from foundation through the final kitchen and bath.

Bathroom Remodeling in Irvine

Bathrooms in Irvine’s older villages often carry the original tract finishes: fiberglass tub surrounds, single-sink vanities, and builder-grade tile. Remodeling here means addressing aging waterproofing, improving ventilation for Irvine’s hot summers, and matching a Mediterranean-influenced interior that fits the home. HOA review rarely touches interior bathrooms unless you’re moving plumbing or adding a window, which keeps the process straightforward. Bathroom Remodeling in Irvine covers design guidance, full construction, and the finishes that hold up in this climate.

Kitchen Remodeling in Irvine

Kitchen remodeling in Irvine means taking an original 1960s-to-2000s tract kitchen, typically built with raised-panel oak cabinets, laminate counters, and fluorescent soffits, and rebuilding it for how people actually cook and gather now. The city’s warm, dry climate makes ventilation and heat management real priorities: a poorly vented range turns a Great Park kitchen into an oven by July. Westminster ADU Builders manages the full kitchen remodel from design guidance through construction and finish work, including Kitchen Remodeling services. We handle the Irvine permit and any village HOA review that touches the project, whether it’s a vent relocation or an exterior wall opening. One team, one contract, from demolition to finished counters.

Cabinet and Countertop Replacement

Signs you need it

Doors are warped or delaminating from years of Irvine’s dry heat, drawer slides bind, or the layout wastes the limited floor plan these tract kitchens were built around.

What it costs in Irvine

Replacing cabinets and countertops in Irvine typically runs $18,000 to $45,000 depending on cabinet grade, countertop material, and whether the layout changes.

How we do it

We measure every opening, order cabinetry and slab material to the existing footprint or revised layout, demo the old boxes and counters, install new cabinets level and secured to the studs, template and set the countertops, and finish with plumbing reconnection and a clean pass.

Full Kitchen Renovation

Signs you need it

The footprint no longer works for your household, appliances are in the wrong places for how you cook, or the original 1980s-90s finishes have reached the end of their lifespan.

What it costs in Irvine

A full kitchen renovation in Irvine, including layout changes, new appliances, flooring, lighting, and finishes, typically ranges from $40,000 to $90,000.

How we do it

We confirm the layout against your existing plumbing and electrical, file the Irvine permits and any needed HOA review, demo to the studs where required, relocate utilities as the plan calls for, rebuild walls and flooring, and set cabinets, counters, appliances, and finish work in sequence.

What Kitchen Remodeling Costs in Irvine

Item Typical range in Irvine
Cabinet and countertop replacement $18,000 – $45,000
Full kitchen renovation with layout changes $40,000 – $90,000
Appliance and fixture replacement with minor updates $8,000 – $22,000

How long does a kitchen remodel take in Irvine?

Cabinet and countertop replacements usually finish in 2 to 3 weeks. A full renovation with layout changes and utility moves typically runs 6 to 10 weeks, with HOA review adding time at the front if exterior vents or windows change.

Will I need HOA approval for a kitchen remodel in Irvine?

If the project stays inside your walls, no. If you move or add a vent termination, enlarge a window, or change any street-facing opening, your village architectural committee will likely require review. We sequence that early so it doesn’t stall the build. Call (833) 620-3521 for a specific answer on your village.
