ADU Company in Highgrove, CA
Kitchen remodeling in Highgrove usually means working inside a mid-century home on a quarter-acre lot, where the original layout fought the Inland Empire heat instead of working with it. Costa Mesa ADU Builders has served Highgrove since 2012, handling full kitchen renovations alongside ADU construction and bathroom remodels, so homeowners get one contractor across every part of the project. Highgrove’s unincorporated Riverside County status changes how permits move, how utilities connect, and what a kitchen remodel should account for. Call (833) 589-8273 for a free estimate on any of the work described here.
Why Highgrove Homes Are Different
Highgrove is one of the last unincorporated pockets of Riverside County where quarter-acre-plus lots are the norm rather than the exception. That matters for two reasons. First, the county building department governs permits, not a city counter, which means inspections and plan reviews follow Riverside County’s process and timeline. Second, many of these older parcels still rely on wells or septic systems, and that directly shapes what an ADU or a major interior remodel can legally connect to.
The housing stock itself skews mid-century: single-story homes with original kitchens, detached garages, and floor plans built before central air was standard. Summer temperatures regularly top 100 degrees, and Santa Ana winds sweep through the brushy parcels east of town. A kitchen remodel here is not just about cabinet boxes and counters. It is about designing ventilation and cooling that hold up through August, and selecting materials that do not warp or fade in direct sun. Detached garages and outbuildings also mean many Highgrove kitchens sit adjacent to structures that get converted into ADUs later, so rough-in decisions made during a remodel matter down the line.
Our Main Highgrove Services
Most Highgrove homeowners call us about two things: adding an ADU on their oversized lot, or bringing a dated bathroom up to modern standard. Both are handled under one contract, start to finish.
ADU Builders in Highgrove
Highgrove’s large-lot, county-governed parcels make it one of the few places in the region where a detached ADU actually fits without a variance fight. We compare prefab and site-built options across seven manufacturers, including Mighty Buildings, Boxabl, and Plant Prefab, to match the right structure to your lot, septic constraints, and budget. Detached garage conversions are common here given how many older homes already have them sitting underused. ADU Builders in Highgrove covers the full scope from site prep through interior finishes.
Bathroom Remodeling in Highgrove
Bathrooms in Highgrove’s mid-century homes tend to be small, with original cast iron plumbing and single-vanity layouts that no longer work for a family. We handle the full gut-and-replace, including subfloor repair under old tile, re-venting, and layout changes that steal space from an adjacent closet. Because many parcels here are on septic, we coordinate with Riverside County on any waste-line scope before walls open. Bathroom Remodeling in Highgrove details the process and typical timelines.

Kitchen Remodeling in Highgrove
Kitchen remodeling in Highgrove means opening up a room that was built for a different climate and a different way of living. The original kitchens in these mid-century homes were closed off, under-ventilated, and never designed for the heat that sits on this part of Riverside County from June through September. We see the same pattern on almost every job: a cramped galley layout with a recirculating range hood, tile counters from the 1960s, and no insulation in the exterior walls. Our work focuses on ventilation, heat-resistant surfaces, and layouts that connect the kitchen to the rest of the home without losing storage. We also coordinate kitchen work with ADU projects so rough-in decisions are made once, correctly, for both structures. For a deeper look at our process, see Kitchen Remodeling.
Full Kitchen Renovation
Signs you need it
Your kitchen layout cannot support a modern cooktop without overloading circuits, the cabinets are delaminating from decades of dry heat, or the room stays unusable in summer without a window unit.
What it costs in Highgrove
A full kitchen renovation in Highgrove typically runs $45,000 to $85,000 depending on layout changes, appliance tier, and whether load-bearing walls come out.
How we do it
We demo to studs, rewire and re-plumb to current code, reframe for the new layout, install insulation and proper range ventilation, then finish with cabinetry, counters, flooring, and a final Riverside County inspection.
Kitchen Cabinet Replacement
Signs you need it
Your cabinet boxes are separating at the joints, the doors no longer close square, or you are storing more on the counters than inside the cabinets.
What it costs in Highgrove
Cabinet replacement here generally lands between $12,000 and $30,000, with stock, semi-custom, and full custom tiers driving most of that spread.
How we do it
We remove existing boxes without damaging drywall, level the new bases, set cabinets in a single day, then return for countertop templating and final alignment once everything settles.

Septic or well constraints rarely change the kitchen number by much, but they can add county review time. We quote line-item pricing upfront so you know exactly what each component costs before anything is ordered.
Does a kitchen remodel in Highgrove require county permits?
Yes, any structural, electrical, plumbing, or mechanical change requires permits through Riverside County, not a city counter. We pull all permits and handle inspections as part of the contract. Call (833) 589-8273 to discuss your scope.
Can you remodel my Highgrove kitchen while also building an ADU?
Yes, and it usually saves money because site mobilization, dumpsters, and permit bundles are shared across both projects. We stage the work so the kitchen stays functional until the swap day. Call (833) 589-8273 for a combined estimate.

We give fixed pricing with no change orders, so the number we quote is the number you pay.

FAQs About ADU Company in Highgrove
Most Highgrove projects start within two to four weeks of a signed contract, depending on permit review timelines at Riverside County. Prefab ADU orders add manufacturer lead time, typically six to fourteen weeks. Call (833) 589-8273 to check current scheduling.
That depends on the parcel. Riverside County environmental health reviews each ADU proposal against the existing septic capacity and well output before approving a connection. We handle that assessment during design so there are no surprises at permit stage. Call (833) 589-8273 for a site-specific read.
Highgrove is unincorporated, so all building permits, plan checks, and inspections go through Riverside County rather than a city hall. The process is often more flexible on large-lot setbacks, but reviews can take longer during peak seasons. We manage the entire county submittal and inspection sequence for you.
