ADU Company in Muscoy, CA
Most Muscoy homeowners call us about one of two things: building an ADU in the backyard, or gutting a 1970s kitchen that hasn’t been touched since the house was built. Kitchen remodeling in Muscoy has its own rhythm because so many homes are mid-century ranches and cottages with compact galley kitchens, original cabinetry, and electrical panels that predate modern appliance loads. The county jurisdiction adds another layer: permits run through San Bernardino County Land Use Services, not a city counter. If you’re weighing a kitchen remodel or an ADU with a full kitchen inside it, call (855) 594-0655 and we’ll walk you through what Muscoy actually requires.
Why Muscoy Homes Are Different
Muscoy is an unincorporated San Bernardino County island completely surrounded by the City of San Bernardino. That matters more than most people realize. Your neighbor’s lot across the street might be city jurisdiction while yours is county, which changes which building department reviews your plans, which fire authority signs off, and how long permitting takes. For ADUs and kitchen remodels alike, the county path is simply different, and you want a builder who has pulled county permits here before.
The housing stock tilts heavily toward older, modest single-story homes: mid-century and 1970s-80s ranch and cottage-style houses. Many sit on large, semi-rural lots with gravel shoulders, detached garages, carports, and outbuildings. That’s actually good news for ADU builds because the space exists, but a lot of those older parcels also carry unpermitted additions or converted garages that have to be legalized before the county will sign off on new work. Muscoy summers are hot and dry, with Santa Ana winds rolling down from the San Bernardino Mountains, so any kitchen or ADU project needs serious insulation, wind-rated roofing, and shaded outdoor transitions. We plan for that from day one.
Our Main Muscoy Services
Two services dominate the calls we get from Muscoy homeowners: full ADU construction and bathroom remodeling, often as part of preparing a home for multi-generational living or rental income. Here’s what each involves in this specific community.
ADU Builders in Muscoy
Muscoy’s large, semi-rural lots make detached ADUs a natural fit, and many properties already have detached garages or outbuildings ready for conversion. The catch is the county jurisdiction. San Bernardino County reviews your plans, county Fire does the fire plan check, and water and septic realities vary lot to lot. We’ve navigated those exact permitting paths, and because we match you to the right prefab brand or site-built plan instead of pushing one product, you get a unit that fits your lot, your budget, and the county’s requirements. See our full ADU Builders in Muscoy page for details on what’s possible.
Bathroom Remodeling in Muscoy
Older Muscoy homes tend to have small, single-sink bathrooms with original cast iron tubs and dated tile. Remodeling usually means reconfiguring the footprint, updating plumbing to modern fixtures, and solving ventilation issues that lead to moisture problems in our hot, dry climate. We handle the full interior scope, so a bathroom remodel pairs cleanly with an ADU build or stands alone as its own project. Read more on our Bathroom Remodeling in Muscoy page.

Kitchen Remodeling in Muscoy
A kitchen remodel in Muscoy usually means working inside a mid-century or 1970s-80s ranch house where the original kitchen was built for a different era: fewer appliances, less counter space, and no concept of an open floor plan. Between the hot summers that make ventilation critical and the county permitting path that can stall uninformed contractors, this is a job that rewards a team who has done it in this exact jurisdiction before. We deliver the full kitchen scope, from demolition to finished cabinetry, countertops, and appliances, without handing you off to another contractor. If you’re weighing a kitchen remodel as part of a larger plan, see our Kitchen Remodeling overview page for how we approach the work.

How we do it
We demo to the studs, reroute plumbing and electrical to code, install new cabinetry and countertops, set appliances, and finish with lighting, ventilation, and a county-ready inspection.

Signs you need it
