ADU Company in Muscoy, CA
Kitchen remodeling in Muscoy means working with homes built between the 1940s and 1970s, many on septic systems and large lots that have never seen a major renovation. We’re Home Base ADU Builders, and we handle kitchen remodels, ADU construction, and bathroom work across Muscoy’s 92405 zip code with an eye on the heat, the wind, and the county permitting path. Call (866) 403-9834 to talk through your project and get a free estimate.
Why Muscoy Homes Are Different
Muscoy is an unincorporated San Bernardino County island surrounded by the City of San Bernardino, which means every ADU or major remodel goes through the County planning and building department, not the City. That single fact changes timelines, permit fees, and which state ADU standards apply. A homeowner on one side of the street might fall under City rules while the neighbor across the way answers to the County. We’ve been working with Muscoy homeowners since 2016 and know which path applies before we ever submit drawings.
The housing stock here runs older and modest. Most homes are mid-century single-family builds on large lots, often with unpaved or partially improved driveways and yards. Many still run on septic rather than sewer, which means a kitchen remodel that moves plumbing or adds square footage can trigger a county septic review before the building permit clears. Muscoy summers regularly push past 100°F, and Santa Ana winds sweep down from the Cajon Pass, so we size insulation, windows, and cooling for real heat loads and specify wind-resistant roofing details. These are not generic California conditions. They’re specific to Muscoy, and they shape every estimate we write.
Our Main Muscoy Services
Most Muscoy homeowners call us first about two projects: adding an ADU to a large lot, or remodeling a bathroom in an older home. Here’s how each one works in this specific market.
ADU Builders in Muscoy
Adding an ADU in Muscoy usually starts with a septic conversation. Because so many lots here rely on individual septic systems rather than sewer, the county often requires a percolation or capacity review before approving a detached unit. The good news is that Muscoy lots tend to be big, which gives you room for a detached ADU with real separation from the main house. We work across the full range: Tuff Shed-based conversions for budget-driven projects, and higher-end prefabs from Abodu, Cover, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. Each has different site requirements, and we’ll tell you which one fits your lot. ADU Builders in Muscoy covers the full breakdown.
Bathroom Remodeling in Muscoy
Bathroom remodels in Muscoy often uncover plumbing that has been in the ground for fifty-plus years. Cast iron drains, outdated venting, and floor joists that have shifted in the dry Inland Empire climate are common. We plan for those discoveries with line-item estimates that tell you what’s contingency and what’s fixed. For homes on septic, we coordinate with the county on any fixture count changes, since adding a bathroom or expanding one can affect system capacity. Bathroom Remodeling in Muscoy has the full scope and local pricing detail.

Kitchen Remodeling in Muscoy
Kitchen remodeling in Muscoy usually means opening up a cramped mid-century layout without overbuilding for the neighborhood. The heat matters here: we specify ventilation and cooling upgrades that actually move air, and we plan cabinet and counter materials that won’t warp in a house that hits 95°F indoors before the AC catches up. A kitchen remodel is also the most common trigger for a septic review in Muscoy, because moving a sink or adding a dishwasher changes the waste line and fixture count. We handle that paperwork as part of the job. See our full Kitchen Remodeling service hub for the broader approach we bring to every project.
Full Kitchen Renovation
Signs you need it
Your Muscoy kitchen has original 1960s cabinetry, the layout traps two people in a corner, or the appliances sit where the sunlight hits hardest and the room overheats by mid-morning.
What it costs in Muscoy
A full kitchen renovation in Muscoy generally runs $18,000 to $35,000 depending on layout changes, material grade, and whether we’re moving plumbing on a septic-connected home.
How we do it
We start with a measured site visit, check the existing plumbing and electrical against County requirements, then demo, frame any layout changes, and rebuild with new cabinetry, counters, flooring, and fixtures in sequence.
Cabinet Replacement and Refacing
Signs you need it
Your cabinet boxes are solid but the doors sag, the finish is worn through, or you want a different look without tearing out walls and redoing the whole room.
What it costs in Muscoy
Cabinet replacement or refacing in Muscoy typically falls between $6,000 and $14,000, with refacing at the lower end and full replacement with new hardware at the higher end.
How we do it
We measure every opening, order doors and drawer fronts to fit the existing boxes, replace or reface in place, and install new hardware with alignment and soft-close adjustments.
What Kitchen Remodeling Costs in Muscoy
| Item | Typical range in Muscoy |
|---|---|
| Full kitchen renovation | $18,000 – $35,000 |
| Cabinet replacement / refacing | $6,000 – $14,000 |
| Countertop replacement | $4,500 – $9,500 |
Prices rise in Muscoy when we’re moving a sink or gas line on a septic-connected home, because that triggers county review and possibly a septic capacity check. Our estimates are line-item and fixed once we’ve done the site visit, so you won’t get a change order for something we should have caught up front.
How long does a kitchen remodel take in Muscoy?
A full kitchen remodel in Muscoy typically takes 6 to 10 weeks from demo to final walkthrough. Septic review or County permit back-and-forth can add 2 to 4 weeks before work starts. Call (866) 403-9834 and we’ll give you a realistic timeline for your specific scope.
Will my Muscoy kitchen remodel trigger a septic review?
Yes, if we’re moving a sink, adding a dishwasher, or changing fixture count, the county often requires a septic review. We handle that filing as part of the permit package. Call (866) 403-9834 for a free estimate that includes the county path specific to your lot.

What Muscoy Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Colleen Pruitt"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Priya Mehta"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
