ADU Company in Newport Beach, CA
Kitchen remodeling in Newport Beach runs $38,000 to $95,000 for a full gut renovation, with most homeowners landing between $50,000 and $70,000 depending on cabinet grade, appliance package, and whether load-bearing walls move. The houses here range from 1940s Balboa Island cottages with galley kitchens to 1990s Newport Coast estates with oversized islands, so no two jobs quote the same. If you’re planning a kitchen update or a full ADU build, call Cottage ADU Builders at (866) 808-7312 for a free estimate.
Why Newport Beach Homes Are Different
Newport Beach housing stock spans nearly a century of construction, and the era of your home dictates what your remodel will uncover. Post-war beach cottages on the Balboa Peninsula and Balboa Island often have kitchens under 100 square feet with outdated electrical panels, corroded galvanized plumbing, and framing that predates current seismic codes. Mid-century ranch homes in Dover Shores and Westcliff tend to have better bones but awkward closed-off floor plans that trap the ocean breeze. Larger custom homes in Newport Coast and Harbor View were built with quality materials but now show dated layouts and appliances from the early 2000s.
The salt air off the Pacific is the silent variable in every Newport Beach job. Exposed metal fasteners, hinges, and appliance surfaces corrode faster here than they do ten miles inland. We spec marine-grade stainless hardware on exterior-facing components and avoid materials that swell or delaminate in persistent humidity. If your kitchen sits against an exterior wall, expect us to inspect for salt-driven moisture intrusion behind the original vapor barrier before we touch the drywall.
Our Main Newport Beach Services
Newport Beach homeowners call Cottage ADU Builders for two things more than anything else: detached and attached ADUs for rental income or family housing, and bathroom remodels that update aging coastal homes. Here’s what each looks like in this city.
ADU Builders in Newport Beach
ADU construction in Newport Beach is a design-and-entitlement project before it’s a building project. Much of the city sits inside the Coastal Zone, which triggers a Coastal Development Permit, and several planned communities add HOA architectural review on top of city review. On Balboa Island and the Peninsula, many lots are legally nonconforming, which often makes a garage conversion the simplest path to a permitted unit. We handle the full sequence: feasibility, plans, CDP submittal where required, site prep, factory or stick-frame build, and utility hookups. ADU Builders in Newport Beach work with Cottage on projects from 400-square-foot studios to 1,200-square-foot two-bedroom units.
Bathroom Remodeling in Newport Beach
Bathroom remodels here run into the same salt-air corrosion and tight floor plates as kitchens, but the moisture load is higher. Older Peninsula homes often have bathrooms with no mechanical ventilation, which means we’re frequently adding exhaust fans, replacing water-damaged subfloor, and waterproofing to current code before tile goes in. Bathroom Remodeling in Newport Beach covers everything from a guest bath refresh in a Harbor View home to a master bath gut renovation in Dover Shores.

Kitchen Remodeling in Newport Beach
Kitchen remodeling in Newport Beach typically costs $38,000 to $95,000, with the spread driven by cabinet construction, appliance brands, and whether you’re keeping the existing footprint or relocating plumbing and gas lines. Homes in the older beach tracts often need electrical service upgrades before a modern kitchen can pass inspection, a line item that inland remodels rarely carry. The full scope of Kitchen Remodeling work we handle includes layout redesign, cabinet replacement, countertop fabrication, appliance installation, flooring, lighting, and the plumbing and electrical behind all of it. Cottage ADU Builders has served Newport Beach since 2012.
Galley Kitchen Expansion
Signs you need it
Your Balboa Island or Peninsula kitchen is a narrow corridor with less than 30 inches of walkway, and two people cannot work in it at the same time.
What it costs in Newport Beach
Galley kitchen expansion and remodel work in Newport Beach typically runs $52,000 to $85,000 when it involves removing a wall, relocating plumbing, and reconfiguring the work triangle.
How we do it
We confirm which walls are load-bearing, design an open plan that respects the original cottage footprint, upgrade the electrical panel, and rebuild the kitchen around a functional island or peninsula where lot dimensions allow.
Full Kitchen Gut Renovation
Signs you need it
Your cabinets are delaminating from decades of salt air, the layout no longer works for how you cook, and appliances are original to a 1980s or 1990s build.
What it costs in Newport Beach
A full kitchen gut renovation in Newport Beach typically ranges from $65,000 to $95,000 including demolition, custom or semi-custom cabinets, stone counters, new appliances, flooring, and finish plumbing and electrical.

We strip to studs, inspect and remediate any moisture or pest damage, rerun electrical and plumbing to current code, then install cabinets, counters, tile, flooring, lighting, and appliances in sequence so you’re never waiting on a missing trade.

Prices in Newport Beach push upward when a project requires a Coastal Development Permit, HOA architectural review, or electrical service upgrade in an older beach cottage. Foundation work on tight Peninsula lots with rear-alley access also carries premium labor costs you won’t see in newer inland neighborhoods.

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