ADU Company in Muscoy, CA
Kitchen remodeling in Muscoy usually means working around a house built between the 1940s and 1970s, often on a large lot with an older electrical panel, a floor plan that was never opened up, and summer heat that punishes a poorly ventilated cooking space. Newport Beach ADU Builders has served Muscoy since 2016, and we take on the full interior scope: cabinetry, countertops, layout changes, plus the kitchen and bathroom finishing that comes with an ADU. Call (844) 934-0236 to talk through your project and get a free estimate.
Why Muscoy Homes Are Different
Muscoy is an unincorporated San Bernardino County island, so ADU permits run through the County’s building and land-use department rather than the City of San Bernardino. That jurisdiction split surprises contractors and homeowners who assume the 92405 ZIP means city rules, and it governs setbacks, septic and utility review for every backyard unit here. When we remodel a kitchen in Muscoy, the same county review often comes into play if the work touches the electrical service, a load-bearing wall, or the existing foundation.
The housing stock is largely older, modest single-family homes on generous lots, many with detached garages, sheds, and unpaved or partially improved driveways and utilities. That usually means an ADU is feasible footprint-wise but requires careful siting around older septic, water, and power service. For kitchens, it means panels that may need an upgrade before you can run modern appliances, and subfloors that sometimes hide decades of layered flooring. The climate here is hot, dry inland Southern California at the base of the San Bernardino Mountains, with intense summer heat and occasional Santa Ana wind events. ADUs and kitchens both need shading, insulation, and cooling design that a coastal contractor might never think about.
Our Main Muscoy Services
Two services dominate the calls we get from Muscoy homeowners: adding a legal ADU on a county-governed lot, and updating the bathrooms inside those older homes while the property is already under construction.
ADU Builders in Muscoy
Most Muscoy ADU conversations start with untangling what’s already on the lot: an unpermitted garage conversion, an informal addition, a septic line that was never mapped. Because Muscoy is county-governed and heavily built-out with informal older improvements, a big part of ADU work here is resolving existing unpermitted structures and utility connections before a new unit can be legally permitted. We handle that process end to end, from county submittal through the final inspection. See our dedicated page on ADU Builders in Muscoy for the full scope.
Bathroom Remodeling in Muscoy
Bathrooms in Muscoy’s older homes frequently sit on original cast-iron drain lines, with moisture damage behind the tile and undersized vent fans that do nothing against inland summer heat. Because we also build ADUs, we often remodel the main-house bath at the same time the new unit goes in, keeping one contractor accountable for the whole property. Read about the specific scope on our Bathroom Remodeling in Muscoy page.

Kitchen Remodeling in Muscoy
Kitchen remodeling in Muscoy usually starts with an older home that has a cramped galley layout, a panel that won’t support modern appliances, and a cooking space that bakes through the inland summer. The work here often includes opening the floor plan, upgrading the electrical service, and designing for cross-ventilation and shade, because a hot kitchen in a San Bernardino County summer is a livability problem every single day. Our team brings the same contractor relationship from permit to punch-list, and we finish ADU kitchens under the same roof. Learn more about our full kitchen scope on our Kitchen Remodeling page.
Cabinet and Countertop Replacement
Signs you need it
Cabinet boxes that have swollen from years of heat and humidity cycles, drawer slides that no longer close, or laminate counters that have delaminated at the edges.
What it costs in Muscoy
Cabinet and countertop replacement in Muscoy typically runs $12,000 to $28,000 depending on the cabinet line and the stone or quartz grade you pick.
How we do it
We measure, order the cabinet run, tear out carefully to avoid damaging intact drywall, and set the new boxes and counters in one sequence so the kitchen is down for the shortest possible time.
Full Kitchen Layout Change
Signs you need it
A galley or closed-off kitchen that traps heat, blocks natural light, and can’t handle two people cooking at once.
What it costs in Muscoy
A layout change that opens walls, relocates plumbing and gas, and replaces finishes typically falls between $25,000 and $45,000 in Muscoy.
How we do it
We pull the structural drawings for any wall removal, move plumbing and electrical to the new positions, patch and level the floor, then install cabinets, counters, and appliances to the new plan.
What Kitchen Remodeling Costs in Muscoy
| Item | Typical range in Muscoy |
|---|---|
| Cabinet and countertop replacement | $12,000 – $28,000 |
| Full layout change with wall removal | $25,000 – $45,000 |
| Electrical panel upgrade (often required) | $2,500 – $5,000 |
Older Muscoy homes push costs up when the electrical panel needs an upgrade, when the subfloor has to be rebuilt, or when a load-bearing wall comes out and the foundation needs a new footing. We write fixed, line-item quotes with no change orders, so you know the number before we start.
How long does a kitchen remodel take in Muscoy?
A cabinet and counter replacement usually takes two to three weeks; a full layout change with wall removal and utility relocation typically runs four to seven weeks, including county inspections on the electrical and plumbing work. Call (844) 934-0236 for a schedule based on your specific kitchen.
Will I need a permit for my kitchen remodel in Muscoy?
Yes for any work that moves electrical, plumbing, gas, or load-bearing walls. Since Muscoy is under San Bernardino County jurisdiction, we pull those permits through the County building department and keep the inspections on our schedule. Call (844) 934-0236 to confirm the scope for your project.
Brands We Service in Muscoy
We’re authorized to build and install from a curated roster that includes Abodu, Cover, and Tuff Shed, and we use James Hardie fiber-cement siding on exterior work because it holds up to Inland Empire heat, wind-driven dust, and foothill fire conditions. Because we work across multiple manufacturers, we can recommend the brand that actually fits your lot and budget. See our brands for the full lineup.

What Muscoy 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."
— Diego Castillo"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Malik Nash"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Steven Nguyen
