ADU Company in Newport Beach, CA
Kitchen remodeling in Newport Beach usually means reshaping a 1950s or 1960s galley inside a home that sits close to the Pacific, where marine air pushes salt into every cabinet hinge and appliance connection. Sunstone ADU Builders handles this work as a dedicated ADU and interior specialist, not a general remodeler dabbling in kitchens. If you’re planning an ADU with a rental-ready kitchen or upgrading the main house while you’re at it, call (855) 949-1913 for a free estimate.
Why Newport Beach Homes Are Different
Newport Beach housing stock splits into two very different animals. East-side neighborhoods built between 1955 and 1970, especially in the 92660 and 92663 ZIPs, are mostly single-story tract homes with small galley kitchens, original post-and-beam framing, and wiring that predates modern appliance loads. Over on Balboa Peninsula and Balboa Island, the 92661 and 92662 lots are famously narrow, the cottages sit close to the alley, and many garages were framed with lumber that’s absorbed decades of salt air.
That salt air is the big variable most inland builders never think about. Marine-layer humidity off the Pacific means cabinet hardware, appliance exteriors, range hoods, and light fixtures rust noticeably faster than they would in Irvine or Fountain Valley. We spec marine-grade fasteners and moisture-resistant materials as standard on Newport Beach kitchen work. The same logic applies to exterior ADU cladding: we specify James Hardie fiber cement siding on most structures because it stands up to coastal humidity better than wood lap siding and gives you a real fire-resistant barrier.
Our Main Newport Beach Services
Two jobs dominate the phones here: building ADUs and remodeling bathrooms. Both require working through Newport Beach’s coastal permit layer, and both benefit from a contractor who knows how Balboa Island setbacks differ from east-side tract lots.
ADU Builders in Newport Beach
Most Newport Beach ADUs are garage conversions or second-story additions over an existing garage, not ground-up cottages. The reason is simple: lot coverage rules on the peninsula and Balboa Island leave almost no room for a detached structure, and coastal zone review complicates any new footprint. We’re authorized builders for prefab brands including Boxabl and Plant Prefab, and we also build traditional stick-frame ADUs where the site calls for it. See the full breakdown on our ADU Builders in Newport Beach page.
Bathroom Remodeling in Newport Beach
Bathroom work in Newport Beach homes often means correcting decades of moisture exposure: rusted fasteners behind walls, failing grout, and ventilation that never kept up with marine fog. We handle the full bathroom scope under the same contract as your ADU structure or as a standalone remodel. Bathroom Remodeling in Newport Beach covers what a typical peninsula bathroom remodel involves and how we sequence the work.

Kitchen Remodeling in Newport Beach
A kitchen remodel in Newport Beach is less about aesthetics and more about undoing what salt air and 60-year-old framing have done to the room. The typical 1950s east-side galley kitchen has a single outlet circuit that can’t support a modern induction cooktop, cabinets whose hinges have been corroding for decades, and a layout built for a family that cooked differently. We rebuild these kitchens to be truly Kitchen Remodeling work that holds up to coastal conditions, and we do it with the same in-house crew that handles ADU interiors, so there’s no handoff to a second contractor.
Cabinet Replacement and Refacing
Signs you need it
Cabinet hinges that bind or show green corrosion, doors that no longer close square, or melamine surfaces that have swollen at the edges from ambient moisture.
What it costs in Newport Beach
Cabinet replacement in Newport Beach typically runs $12,000 to $35,000 depending on kitchen size and cabinet grade; refacing runs $7,000 to $16,000.
How we do it
We remove the old boxes, assess wall framing for moisture damage, install marine-grade cabinet bases, and mount doors with stainless steel hinges rated for coastal air.
Countertop and Backsplash Installation
Signs you need it
Laminate counters that have bubbled at the seams, tile grout that stays dark with mildew, or a backsplash that has pulled away from the wall behind the range.
What it costs in Newport Beach
Mid-range quartz countertops in Newport Beach kitchens typically run $4,500 to $9,000 installed, while a full tile backsplash adds $1,800 to $4,200.
How we do it
We template the counters after cabinets are set, cut and install the stone, and run the backsplash with epoxy grout that resists the marine humidity better than standard cement grout.
Appliance Upgrades and Layout Changes
Signs you need it
You’re plugging a toaster and a microwave into the same outlet because the kitchen has two circuits total, or the refrigerator blocks the only walkway when its door is open.
What it costs in Newport Beach
A kitchen layout change that moves plumbing and electrical typically adds $8,000 to $25,000 to the remodel, on top of appliance costs.
How we do it
We map the current circuits, run new dedicated lines for the cooktop and wall oven, move the sink drain inside the existing wall where possible, and rework the layout so appliance doors clear every walkway.

Will a kitchen remodel in Newport Beach require coastal permits?
