ADU Company in Fountain Valley, CA
Kitchen remodeling in Fountain Valley usually means working inside a 1960s or 1970s single-story ranch where the original footprint, wiring, and plumbing are all still under the same stucco they were installed with fifty years ago. That changes the job: walls hide old copper and knob-and-tube, and load-bearing decisions have to respect truss spans that were never meant for open concepts. Cottage ADU Builders handles the full scope, from permit plans to punch-list, so you’re not juggling a designer, a cabinet shop, and a plumber on your own. Call (866) 808-7312 for a free estimate.
Why Fountain Valley Homes Are Different
Fountain Valley is built almost entirely of 1960s and 1970s single-story tract homes on generous lots, most of them 6,000 to 7,000 square feet with attached two-car garages and wood-frame stucco construction. That housing stock creates a specific remodeling profile. The original kitchens are compact, often closed off from the living areas, and the plumbing is aging. But the lots themselves give you room to work: wide side yards and rear alleys are common, which means a kitchen bump-out or a full rear addition is usually possible without eating into a cramped setback.
The coastal climate also shapes how we build here. Fountain Valley gets very little rain, but the marine layer sits over the city most mornings, and Santa Ana winds can push temperatures up quickly in the fall. That means our kitchen projects don’t need heavy HVAC integration, but we do plan for cross-breezes, east-west window orientation, and insulation details that keep a west-facing kitchen from baking in October. The city’s building department enforces energy code on kitchen remodels when you touch walls or move gas lines, so we pull the permits and schedule the inspections as part of the job.
Our Main Fountain Valley Services
Most Fountain Valley homeowners call us about one of two projects: adding a detached ADU in the backyard, or updating a bath or kitchen inside the existing house. Both run through the same Fountain Valley building department, and both benefit from a contractor who knows the city’s specific planning rules.
ADU Builders in Fountain Valley
Fountain Valley has its own ADU ordinance layered on top of California state law, and the rules differ from what Huntington Beach or Westminster enforce. Detached units are capped at 16 feet in height and need a minimum 4-foot rear setback. On many 1960s lots, that rear setback is the tricky part: block-wall fences sit right on the property line, so we’re often fitting the ADU footprint between the back of the house and that wall without triggering a lot-coverage variance. We work with prefab and modular systems where they make sense, and stick-frame where they don’t. Read more about ADU Builders in Fountain Valley.
Bathroom Remodeling in Fountain Valley
Original 1960s and 1970s bathrooms in Fountain Valley are almost always small, with cast-iron tubs, outdated tile, and single-gang electrical that can’t support modern fixtures. The real work is usually behind the walls: replacing galvanized supply lines, adding GFCI circuits, and waterproofing showers to current code. Because the houses sit on post-tension slabs, moving a toilet or shower drain means cutting concrete, which we coordinate with plumbers and inspectors before floors go down. See Bathroom Remodeling in Fountain Valley for the full scope.

Kitchen Remodeling in Fountain Valley
Kitchen remodeling in Fountain Valley typically means opening a closed-off galley kitchen into the dining or living room, replacing 50-year-old plumbing and wiring, and rebuilding the space around how you actually cook. The original ranch homes here were framed with simple span trusses, so removing a wall is rarely a structural guessing game, but moving gas and drain lines across a post-tension slab requires planning, permits, and a contractor who has done it in Fountain Valley’s specific housing stock. That’s the job we do: from permit plans through cabinet install, under one contract. For a broader look at the service, see Kitchen Remodeling.
Wall Removal and Open-Concept Work
Signs you need it
You’re cooking in a narrow galley with one counter run, and the dining room feels like wasted square footage.

Wall removal and open-concept work in Fountain Valley, including beam installation and finish work where needed, typically runs $8,000 to $25,000 depending on the length of the wall, mechanical reroutes, and flooring match.
How we do it
We assess the truss direction, confirm load points, pull the structural permit, install the beam or header, reroute any plumbing or electrical, then patch and finish the ceiling and floors to match.
Full Kitchen Renovation
Signs you need it
Your cabinets are delaminating at the edges, the layout doesn’t work for two people, and the electrical can’t support a modern appliance circuit.

What Fountain Valley Customers Say
"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"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Ernesto Hernandez
