ADU Company in Aliso Viejo, CA

Kitchen remodeling in Aliso Viejo means working inside homes built during the 1980s and 1990s master-plan buildout, where original layouts are tight, soffits crowd ceiling lines, and the Mediterranean styling that defines the city often hides dated wiring and plumbing behind stucco walls. We’re Cottage ADU Builders, and we’ve served Aliso Viejo since 2012, handling everything from garage conversions to full kitchen gut-and-rebuilds in the 92656 and 92698 ZIP codes. If you’re weighing a kitchen upgrade, give us a call at (866) 808-7312 for a free estimate.

Why Aliso Viejo Homes Are Different

Aliso Viejo is about as close to a fully planned city as Orange County gets. Nearly every home sits inside an HOA, which means a kitchen remodel or ADU project has to clear architectural review before the city even looks at a permit application. We regularly work with homeowners in the Glenwood and Westridge communities who need help understanding how CC&R restrictions on exterior changes, window placement, or construction hours interact with Aliso Viejo’s municipal code.

The housing stock itself was built fast and in volume. Original kitchens in these 1980s and late-1990s homes often have 8-foot ceilings, fluorescent soffit boxes, and cabinetry that was installed before modern appliance widths became standard. Floor plans are compact, so gaining six inches of counter depth or opening a wall changes how the whole first floor functions. The coastal-inland climate means cooling matters more than heating, and homes on the eastern edge near the ridge lines can fall into wildfire-interface zones that bring their own material requirements, especially for any exterior wall or vent work tied to a kitchen or ADU.

Our Main Aliso Viejo Services

Most Aliso Viejo homeowners call us about two things: adding a second unit or refreshing the inside of one they already have. Both run through the same HOA and permit channels here.

ADU Builders in Aliso Viejo

Aliso Viejo’s HOA density shapes every ADU conversation. Detached units often run into lot-coverage limits, so many projects become garage conversions or attached junior units. We help homeowners sort prefab options against CC&R setback rules and architectural review before money gets spent. ADU Builders in Aliso Viejo covers the full process from feasibility to finish.

Bathroom Remodeling in Aliso Viejo

Bathrooms in Aliso Viejo’s original homes are small, and many share walls with kitchens or laundry rooms, which makes reconfiguring plumbing more involved than a like-for-like swap. We work with the same HOA parameters as on larger jobs because two-story townhomes in 92656 often have bathrooms over living space. Bathroom Remodeling in Aliso Viejo walks through what’s typical for these homes.

Kitchen Remodeling in Aliso Viejo

Kitchen remodeling in Aliso Viejo usually means taking a 1990s footprint, removing the soffits and fluorescent light boxes, and replacing everything down to the subfloor and drywall. Many of these kitchens sit under 8-foot ceilings, so tall-cabinet and full-height-backsplash decisions matter more than they would in newer Orange County builds. Because most Aliso Viejo homes are inside HOAs, we coordinate architectural review when a remodel touches exterior walls, vents, or windows. This is the service we perform most often here, and it pairs naturally with our Kitchen Remodeling practice across Southern California.

Cabinet and Layout Reconfiguration

Signs you need it

Your original 1990s cabinet boxes are delaminating at the door edges, and the single-door pantry no longer holds a week of groceries for a family of four.

What it costs in Aliso Viejo

Full kitchen cabinet replacement and layout changes in Aliso Viejo typically run from $25,000 to $45,000 depending on cabinet lines, counter runs, and how much wall movement is involved.

How we do it

We measure the existing footprint, build a 3D layout with your appliance sizes, strip the old boxes, then set new ones level on Aliso Viejo floors that are rarely perfectly flat after 30 years.

Countertop and Island Upgrade

Signs you need it

Tiles have cracked along grout lines where the original plywood substrate flexed, or you want a single-level island instead of the raised breakfast bar that dates these homes.

What it costs in Aliso Viejo

A quartz or porcelain counter and island upgrade here usually falls between $8,000 and $18,000, with natural stone at the higher end once fabrication and sink cutouts are included.

How we do it

We template after the cabinets are set, reinforce the island base for cantilevered overhangs, and coordinate stone fabrication while plumbing rough-in moves forward.

For the cabinets and counters most Aliso Viejo kitchens need, the numbers above reflect what we quote in practice. A full-gut kitchen in this city, with new layout, finishes, lighting, and plumbing, sits between $45,000 and $75,000. Small refresh work that keeps the footprint, like resurfacing cabinets and swapping counters, runs $15,000 to $25,000.

What Kitchen Remodeling Costs in Aliso Viejo

Item Typical range in Aliso Viejo
Cabinet replacement and layout change $25,000 – $45,000
Countertop and island upgrade $8,000 – $18,000
Full kitchen gut and rebuild $45,000 – $75,000

How long does a kitchen remodel take in Aliso Viejo?

Plan on 6 to 10 weeks for a full kitchen remodel in Aliso Viejo, with HOA architectural review adding up to two weeks before we can pull permits. Smaller counter and cabinet swaps finish in 2 to 3 weeks. Call (866) 808-7312 for a schedule based on your specific scope.

Will my Aliso Viejo HOA slow down a kitchen remodel?

Yes, if the work touches exterior walls, windows, or venting. Interior-only remodels usually bypass full HOA review, but we check your community’s guidelines before ordering materials. Call (866) 808-7312 and we’ll review your CC&Rs with you.

What Aliso Viejo 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."

— Shane 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."

— Amanda Walsh

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

— Lucia Flores
