ADU Company in Irvine, CA
Kitchen remodeling in Irvine means working inside homes built between the 1970s and today, mostly Mediterranean and Spanish-revival stucco with tile roofs, where the original kitchens were sized for a different era of living. Irvine’s warm, dry climate keeps remodeling work moving year-round, but the real challenge is the master-planned village layout: many kitchens sit over concrete slab foundations that make moving plumbing or gas lines more involved than in older pier-and-beam homes. Costa Mesa ADU Builders has served Irvine since 2012, and we handle everything from a first-floor kitchen on a slab to kitchens in homes where the HOA wants design review before the first cabinet comes out. Call (833) 589-8273 to schedule your free kitchen estimate.
Why Irvine Homes Are Different
Irvine is a master-planned city built almost entirely by the Irvine Company. That matters for remodeling and ADU work in ways most homeowners don’t see coming. The villages, Woodbridge, Northwood, Turtle Rock, and the neighborhoods around the Spectrum and Great Park, each have their own HOA architectural review boards, and those boards can reject a plan that the city already approved. Before the city permit stage even begins, an ADU or a major exterior change often needs HOA design committee sign-off, and each village’s CC&Rs treat setbacks, roof material, and exterior color differently. Most Irvine lots are post-1970 tract parcels with tight rear setbacks and little to no alley access. Attached two-car garages are the norm, driveways are short, and rear yards are often small. That means an ADU here usually goes over or in place of a garage, or tucks into a narrow rear setback, not sprawling across a big lot the way it might in an older city. Add in the intense summer sun and heat gain on west-facing walls and tile roofs, and an Irvine project needs insulation, shading, and cooling designed in from the start, not bolted on later.
Our Main Irvine Services
Irvine homeowners call us most often for two things: building an ADU and remodeling a bathroom. Both happen inside the same HOA and lot-constraint realities, and both benefit from a contractor who already knows how each village works.
ADU Builders in Irvine
An Irvine ADU lives or dies on HOA CC&R approval and design-review compatibility. We’ve built across the villages and know the questions each board asks about rooflines, setbacks, and exterior finishes. Our work spans both prefab and site-built methods, so you get a genuine comparison: a panelized or modular unit like a Mighty Buildings or Boxabl product that goes up faster, or a stick-built ADU matched to your existing stucco and tile. Given the lot sizes and garage placements common in Irvine, most clients end up with a garage conversion ADU or a detached unit sited in the narrow rear setback. See the full service breakdown at ADU Builders in Irvine.
Bathroom Remodeling in Irvine
Bathrooms in Irvine’s tract homes share a few traits: original tile surrounds that are decades old, standard alcove tubs, and slab foundations that make relocating a toilet or shower drain more deliberate. We remodel bathrooms across Irvine’s ZIP codes, including 92602 and 92603, handling everything from a guest bath refresh to a primary bath reconfiguration. Where the bathroom shares a wall with a planned ADU, we can sequence both scopes under one contract so the plumbing rough-in happens once, not twice.

Kitchen Remodeling in Irvine
Kitchen remodeling in Irvine usually means unwinding a 1970s-to-1990s galley or U-shaped kitchen in a stucco tract home, often on a concrete slab, where the plumbing and gas lines are exactly where the original builder put them. Irvine’s climate means the kitchen also has to survive direct sun on the west side of the house without turning into a heat trap, so we build in ventilation, shading, and efficient cooling as part of the layout, not an afterthought. Our Kitchen Remodeling work covers the full scope, from cabinet replacement to a full reconfiguration, and because we also build ADUs, a new kitchen in the ADU and a refreshed kitchen in the main house can happen in the same project phase.
Cabinet and Countertop Replacement
Signs you need it
Cabinet boxes are water-damaged, doors sag, drawer slides are failing, or the layout wastes the narrow kitchen footprint common in Irvine’s tract homes.
What it costs in Irvine
Cabinet and countertop replacement in Irvine typically runs $18,000 to $55,000 depending on cabinet line, countertop material, and whether the existing layout stays put.
How we do it
We measure the existing footprint, order cabinets to fit Irvine’s typical kitchen sizes, and remove and replace in sequence so you keep a working kitchen as long as possible.
Full Kitchen Reconfiguration
Signs you need it
The kitchen is closed off from the living space, has a load-bearing wall in the wrong place, or the sink and range are squeezed against a slab foundation that makes relocating utilities a two-to-four-week addition to the schedule.
What it costs in Irvine
A full kitchen reconfiguration in Irvine typically runs $35,000 to $90,000 depending on structural work, utility relocation, and finish level, with slab penetrations driving the higher end.
How we do it
We open the walls, reframe as needed with an engineer’s stamp for any structural change, relocate plumbing and gas on the slab, and rebuild the kitchen around the new layout.
What Kitchen Remodeling Costs in Irvine
| Item | Typical range in Irvine |
|---|---|
| Cabinet and countertop replacement | $18,000 – $55,000 |
| Full kitchen reconfiguration | $35,000 – $90,000 |
| Kitchen plus adjacent laundry or pantry | $28,000 – $70,000 |
Does a kitchen remodel in Irvine require HOA approval?
Interior kitchen work that doesn’t change the exterior footprint or roofline usually doesn’t trigger HOA design review. If your reconfigure adds a window, changes a wall that affects the exterior, or extends into new square footage, your village’s CC&Rs likely require HOA sign-off before the city permits.
Can I remodel my Irvine kitchen and add an ADU at the same time?
Yes, and it’s often the smartest sequence if both projects touch plumbing or electrical. We can rough in the ADU and the kitchen remodel under one contract, which means one permit package, one design team, and one site schedule instead of two contractors stepping on each other.
Brands We Service in Irvine
We work across seven prefab ADU manufacturers so the recommendation fits your lot and budget, not our preferred vendor. In Irvine, that often means comparing a Panel-style build from Plant Prefab or a compact Boxabl unit for tight rear setbacks, or a Tuff Shed structure for a garage replacement. Parts for the brands we regularly place are sourced regionally, keeping lead times predictable. See the full roster on our brands page.
