ADU Company in Highgrove, CA
Kitchen remodeling in Highgrove usually means opening up a cramped mid-century floor plan inside a home built between 1940 and 1975, often without disturbing the original framing or the existing slab foundation. We work on these older Highgrove homes constantly, and the job is different here than in newer Riverside subdivisions: walls hide asbestos-era materials, cabinets sit on settled floors, and the unincorporated county permit process adds a layer most city contractors never deal with. Sunburst ADU Builders handles the full scope, from demolition through finished kitchen and bathroom work, so you’re not juggling three separate crews. Call (855) 676-6807 to talk through your project and get a free estimate.
Why Highgrove Homes Are Different
Highgrove is unincorporated Riverside County, which means every ADU and kitchen remodel here follows county building rules rather than a city’s municipal code. That single fact changes how we approach every project. County staff process permits on their own timeline, and setback, height, and parking standards can differ from what a contractor working in nearby Grand Terrace or Riverside might assume. We’ve learned to schedule pre-application meetings with Riverside County planning before we finalize drawings, because catching an interpretation issue early saves weeks on the back end.
The housing stock adds another layer. Most Highgrove homes are mid-20th-century builds on generous lots, and many still have their original detached garages or accessory structures that were never brought up to code. When we remodel a kitchen in these homes, we’re typically working around older framing, settled slabs, and electrical panels that predate modern load requirements. The hot, dry inland climate also shapes the work: long summers with triple-digit heat mean we specify ventilation, shading, and efficient cooling in every kitchen design, and water-wise fixtures are a practical necessity here, not a talking point. Highgrove isn’t a tract-home community, and the houses don’t respond to one-size-fits-all solutions.
Our Main Highgrove Services
Homeowners in Highgrove call us most often about two things: building an ADU on their existing lot, and remodeling a bathroom to match the quality of the rest of the home. Both projects carry the same unincorporated county realities, and both benefit from a single team that knows the local permit path.
ADU Builders in Highgrove
Building an ADU in Highgrove almost always starts with a question: do we convert the existing detached garage or replace it? Because so many homes here have older, non-conforming accessory structures, conversion is often the fastest and most cost-effective path, but it comes with county code considerations around setbacks and height that a city contractor may not anticipate. We compare prefab, modular, and custom options side by side so the decision fits your lot, budget, and rental timeline. ADU Builders in Highgrove covers the full process, from county pre-application through final inspection.
Bathroom Remodeling in Highgrove
Bathrooms in Highgrove’s older homes often hide the same issues as the kitchens: dated plumbing, poor ventilation, and layouts that waste space. Remodeling here means planning for the area’s hard water, limited drainage slopes on older slabs, and the county inspection requirements that come with moving or adding plumbing lines. We handle the full scope, including finish carpentry, tile, and fixtures, so the finished bath matches the quality of your new ADU or remodeled kitchen. Bathroom Remodeling in Highgrove explains what a typical Highgrove bath project involves.

Kitchen Remodeling in Highgrove
A kitchen remodel in Highgrove typically runs $25,000 to $65,000 for a full mid-century tear-out with new cabinets, counters, flooring, and appliance rough-ins, though smaller refreshes fall below that range and high-end builds go higher. The homes here weren’t designed for open-concept living, so most projects involve some structural thinking: removing a load-bearing wall, relocating plumbing on a settled slab, and upgrading an electrical panel that still has cloth-wrapped wiring. We approach every Highgrove kitchen as its own small construction project, with the same attention we give to ADU builds. For a deeper look at the service itself, see Kitchen Remodeling.
Full Mid-Century Remodel
Signs you need it
Original cabinets with failing hinges, a closed-off floor plan, and outdated wiring that can’t support modern appliances signal a full remodel rather than a refresh.
What it costs in Highgrove
A full remodel with cabinet replacement, countertops, flooring, and lighting typically runs $35,000 to $65,000, with the top end including structural changes like wall removal or slab plumbing work.
How we do it
We demo to the studs, handle county inspections for any structural or electrical changes, rebuild with new cabinets, counters, and flooring, and finish with trim, paint, and appliance installation.
Cabinet and Counter Refresh
Signs you need it
Boxes are solid but doors are worn, and the layout works while the surfaces and hardware look decades old.
What it costs in Highgrove
A refresh with refaced or new doors and new countertops generally runs $12,000 to $25,000, depending on material choices and linear footage.
How we do it
We remove doors and hardware, reface or replace fronts and drawer boxes, install new counters and sinks, and re-plumb the fixture, leaving the existing layout intact.

Prices in Highgrove climb when a project involves moving plumbing on an older slab, opening load-bearing walls, or replacing original electrical panels that don’t meet current code. County permit fees and the slightly longer inspection timelines in unincorporated Riverside County also contribute. Sunburst ADU Builders gives written, line-item quotes before work starts, and we don’t hit you with change orders mid-project unless you change the scope yourself.

What Highgrove Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Hector Torres"Unit came out great and the tenant is happy. The timeline ran long, largely because of how slow the city was on plan check, though a couple of the delays were scheduling on their end."
— Jodi Reed"He was honest that our lot had a slope problem that would add real cost, before we signed anything."
— Katie Parker
