ADU Company in Muscoy, CA
Kitchen remodeling in Muscoy means working with homes built between the 1950s and 1970s, where closed-off floor plans, worn cabinetry, and outdated electrical panels are the norm. We’re Westminster ADU Builders, and we approach Muscoy kitchen remodels with the same discipline we bring to ADU construction: honest assessments, clear pricing, and finishes that hold up to triple-digit summers. Call (833) 620-3521 when you’re ready to talk through your kitchen.
Why Muscoy Homes Are Different
Muscoy is unincorporated San Bernardino County, which changes how permits get pulled. You’re not dealing with a city building department. You’re dealing with San Bernardino County Land Use Services, and that means every kitchen remodel that touches plumbing, electrical, or walls moves through county review. Older Muscoy homes typically have 100-amp electrical panels, which is rarely enough for modern kitchens with induction cooktops, double ovens, and dedicated circuits for refrigerators and dishwashers. We routinely see 200-amp panel upgrades as the first line item on a Muscoy kitchen job.
The housing stock itself presents specific conditions. Many of these homes sit on generous lots with mature trees, and the houses have settled over decades. Subfloors are uneven. Plumbing supply lines through concrete slabs corrode in the alkaline soil, which shows up as low water pressure at the kitchen sink. Summer temperatures that exceed 100°F for weeks at a time make ventilation design a real priority: a kitchen without proper exhaust turns the whole house into an oven. None of this is insurmountable, but a remodel that ignores these local realities will cost more later.
Our Main Muscoy Services
The two services Muscoy homeowners call us about most are ADU construction and bathroom remodeling. Both share the same local conditions: county permits, septic and electrical capacity questions, and older homes that need utility work before finish work begins.
ADU Builders in Muscoy
Muscoy’s unincorporated status and large, semi-rural lots make detached ADUs a realistic option for many properties. But the approval path runs through San Bernardino County, and that often means addressing septic capacity and water service before any foundation gets poured. We know the county’s Land Use Services process and we build both prefab and site-built ADUs, so the recommendation fits your lot, not our vendor list. Learn more on our dedicated ADU Builders in Muscoy page.
Bathroom Remodeling in Muscoy
Older Muscoy homes often have one bathroom doing too much work, and remodels here frequently uncover cast-iron drain lines and insufficient venting. Since many properties rely on septic systems, drain line condition matters more than in city neighborhoods on sewer mains. We plan bathroom remodels around the plumbing reality first, then the finishes. Our dedicated Bathroom Remodeling in Muscoy page covers pricing and scope in detail.

Kitchen Remodeling in Muscoy
Kitchen remodeling in Muscoy usually means opening up a cramped 1950s-to-1970s galley kitchen in a house that was never designed for how families cook today. The electrical panel is undersized, the plumbing is tired, and the layout traps heat in a climate where summer temperatures regularly exceed 100°F. That’s the problem we solve: a kitchen that works for the way you actually live, built to handle Muscoy’s heat and the quirks of older construction. Westminster ADU Builders specializes in ADUs and the kitchens and bathrooms inside them, so this is our core work, not a side trade. You can see how our broader approach works on our Kitchen Remodeling page.
Full Kitchen Remodel
Signs you need it
Your kitchen’s layout hasn’t changed since the house was built, you’re working around dead corners, and cabinets are delaminating from decades of heat and dry air.
What it costs in Muscoy
A full kitchen remodel in Muscoy typically falls between $45,000 and $85,000 depending on footprint, electrical scope, and finish level.
How we do it
We demo to studs, upgrade electrical to 200 amps where needed, reconfigure the layout, then install new cabinetry, countertops, flooring, and appliances with proper exhaust ventilation for Muscoy summers.
Countertop and Cabinet Replacement
Signs you need it
Your cabinets are structurally sound but the doors sag, the laminate counters are burned or swollen, and you want a functional update without moving walls.
What it costs in Muscoy
Countertop and cabinet replacement in Muscoy generally runs between $12,000 and $30,000, depending on material choices and cabinet count.
How we do it
We remove existing tops and doors, repair or replace cabinet boxes, install new doors, drawer fronts, and countertops, then re-level everything on settled Muscoy subfloors.
What Kitchen Remodeling Costs in Muscoy

| Countertop and cabinet replacement | $12,000 – $30,000 |

What pushes price up in Muscoy is panel work and concealed plumbing. A kitchen that needs a new service panel, re-piped supply lines, and a subfloor level adds real cost before the first cabinet goes in.
Can you work with my home’s old plumbing and electrical?
Yes, and we typically must. Older Muscoy homes commonly need a 200-amp panel upgrade and supply line replacement before new appliances and fixtures can be installed safely. We plan for this from the first walkthrough so there are no mid-project surprises. Call (833) 620-3521 for an exact scope.
How long does a kitchen remodel take in Muscoy?
Most full kitchen remodels in Muscoy take 8 to 12 weeks, with an extra 2 to 4 weeks if county permit review or a panel upgrade adds steps. We’ll give you a written timeline at the free estimate. Call (833) 620-3521 to schedule yours.

What Muscoy Customers Say
"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Daniel Norris"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Farah Hassan"He gave us a realistic rental number for the finished unit rather than the optimistic one, and it's renting for about what he said."
