ADU Company in Muscoy, CA
Kitchen remodeling in Muscoy usually means working with a mid-century home that was built before modern electrical loads, on a larger lot where the kitchen might open to a converted garage or a future ADU. The heat here on the valley floor is intense, so ventilation and cooling are part of the design conversation, not an afterthought. Guest House ADU Builders handles kitchen work with the same ADU-specialist lens we bring to every Muscoy project. Call (833) 863-7015 for a free estimate.
Why Muscoy Homes Are Different
Muscoy is an unincorporated San Bernardino County island, which means ADU and remodel permits here run through the County, not the City of San Bernardino next door. That distinction catches a lot of homeowners off guard. They assume the city’s rules apply, then discover the County has its own review path, its own inspectors, and its own timeline. We work with the County process directly, so the permitting sequence is something we plan for from day one rather than learning on the job.
The housing stock shapes the work, too. Most Muscoy homes are older single-story builds, many from the 1950s and 1960s, with detached garages and outbuildings on flat, generous lots. Those lots are exactly why detached ADUs and kitchen additions are more feasible here than a few blocks south in the denser San Bernardino grid. But the same homes often have 100-amp panels, original framing, and kitchens last touched when laminate counters were new. A remodel here starts with the electrical reality, not the backsplash.
Summer in Muscoy is hot, and Santa Ana winds are real. We spec range hoods that actually pull air, cooling that can handle the valley floor, and materials that don’t warp or swell in dry heat. On kitchen jobs near the wildland edge, we pay attention to ember-resistant detailing just like we would on an ADU exterior.
Our Main Muscoy Services
Muscoy homeowners call us most often about two things: adding a unit to a large lot and upgrading a bathroom in a home that hasn’t been touched in decades. Here’s how each works in Muscoy specifically.
ADU Builders in Muscoy
Muscoy’s lot pattern is the reason ADUs work here. The flat, oversized parcels make detached units and garage conversions genuinely practical, often with room for a rear setback that would never pencil out on a city lot in San Bernardino. The first thing we check on a Muscoy ADU is sewer and water: much of this area runs on septic and wells, and that capacity question is the make-or-break before anyone draws plans. We compare prefab options from Cover, Dvele, and Boxabl against site-built, and we match the system to your lot and budget. ADU Builders in Muscoy is the full breakdown of how we approach builds here.
Bathroom Remodeling in Muscoy
Older Muscoy homes tend to have small bathrooms with cast-iron plumbing that’s seen better days. A bathroom remodel here often means re-piping, waterproofing for a house that sits through hot dry summers, and bringing the electrical up to code for things like exhaust fans and heated floors. We handle the whole scope, from demo to trim, and coordinate with the same County inspections we already know from ADU work. If your bathroom shares a wall with a future ADU or a converted garage, we plan the plumbing stubs so the projects don’t fight each other. Bathroom Remodeling in Muscoy covers the full range of what we do.

Kitchen Remodeling in Muscoy
A kitchen remodel in Muscoy usually starts with a mid-century house that’s never had a major kitchen update. That means we’re opening walls that still have original wiring, discovering plumbing that isn’t vented the way it should be, and working around the lot access and County inspection realities that shape everyday construction here. The heat also plays a role: a well-planned ventilation system and HVAC supply into the kitchen matter more on the inland valley floor than they do near the coast. We approach every Muscoy kitchen job with the same discipline we bring to ADU work, because the systems are what make or break the room. Our full Kitchen Remodeling service covers everything from minor updates to full reconfigurations.
Cabinet and Countertop Replacement
Signs you need it
Doors that won’t stay square, delaminating faces, particleboard that has swelled from years of heat cycling, or counters that have outlived their seams are all signs it’s time in a Muscoy home.
What it costs in Muscoy
Cabinet refacing in Muscoy typically runs $4,000 – $9,500, while full custom cabinet installs land between $7,000 – $20,000, and countertop replacement ranges $2,000 – $6,500 installed.
How we do it
We measure, order from local cabinet suppliers that stock for inland delivery schedules, prep the existing boxes or pull them entirely, then set the new cabinets and counters with hardware and alignment that holds up to dry heat.
Full Kitchen Renovation
Signs you need it
When the layout doesn’t function for how you actually cook, the electrical can’t support modern appliances, or the room needs to open toward a future ADU or rear yard, it’s a full renovation, not a facelift.
What it costs in Muscoy
Full kitchen renovations in Muscoy typically start around $15,000 and run $25,000 – $50,000 depending on scope, with load-bearing changes and utility upgrades pushing toward the higher end.
How we do it
We pull County permits, upgrade the panel and circuits before closing any walls, re-route plumbing for the new layout, hang drywall, and then install flooring, cabinets, counters, tile, and fixtures in sequence.

How long does a kitchen remodel take in Muscoy?
Most Muscoy kitchen remodels run 4 – 8 weeks from demo to final inspection. Cabinet-only jobs can finish in 2 – 3 weeks; full renovations with electrical and layout changes take longer, especially with County inspection scheduling. Call (833) 863-7015 for a timeline on your specific scope.

We price everything upfront, in writing, so there are no surprises after the permit is pulled. The number on the estimate is the number on the invoice unless you change the scope.
