ADU Company in Highgrove, CA
Kitchen remodeling in Highgrove is a different animal than it is in newer Riverside-area tracts. Most of the homes here were built in the mid-century era and haven’t seen a cabinet or counter update since the original construction, which means we’re regularly working with dated layouts, undersized electrical panels, and plumbing that predates modern code. Holloway ADU Builders has served Highgrove since 2016, and our team handles everything from the first demolition swing to the final cabinet adjustment. If you’re sizing up a kitchen renovation on one of Highgrove’s half-acre lots, call us at (855) 617-6356 for a free estimate.
Why Highgrove Homes Are Different
Highgrove sits in the unincorporated county pocket between Grand Terrace and Colton, and the homes reflect a different era of Inland Empire building. Most stock dates from the 1950s through the early 1980s: ranch-style and modest custom builds on lots that routinely run half an acre or larger. That’s a planning advantage for major additions, but it also means the infrastructure is old. We regularly find galvanized supply lines, 100-amp panels that can’t support a modern kitchen’s appliance load, and structural framing that predates current shear-wall requirements.
The big differentiator here is the county layer. Highgrove doesn’t have its own building department. Every permit runs through Riverside County, and many properties are on private wells and septic systems rather than municipal utilities. For kitchen work, the septic piece matters less than it does for a detached ADU, but the county review process still shapes timelines and scope decisions. Homeowners who hear “California makes it easy” discover that Riverside County’s plan check and inspection sequence sets the real pace. We know that sequence, and we build schedules around it rather than pretending it doesn’t exist. Climate is the final variable. Highgrove gets genuine Inland Empire heat, with summer runs over 100 degrees and Santa Ana winds in the fall. Kitchen ventilation, window selection, and AC-adjacent design details get more attention here than they would in the coastal cities that most national design blogs assume you live in.
Our Main Highgrove Services
Highgrove homeowners call us about two things more than anything else: adding a detached ADU to a large county lot, and bringing a tired mid-century bathroom up to modern standard. Both run through the same Riverside County permitting reality, and both benefit from a contractor who’s done this before in the unincorporated zone.
ADU Builders in Highgrove
Highgrove’s lot sizes make detached ADUs genuinely feasible, but the county’s septic and site-plan requirements add a layer that smaller, sewer-served cities never deal with. We walk clients through perc tests, leach-field capacity, and county setback rules before they commit to a brand or build method. Holloway works with Abodu, Dvele, and Mighty Buildings among others, and we also handle Tuff Shed conversions for entry-level budgets. ADU Builders in Highgrove is where the full breakdown lives. One team from foundation to finished kitchen, with the county layer handled from day one.
Bathroom Remodeling in Highgrove
Most Highgrove bathrooms are original to houses built forty to seventy years ago. That means single vanities, tub-shower combos with failing valves, and floor framing that has to be opened up before new tile goes down. We handle the plumbing, waterproofing, and finish work as one scope, and we make sure the county inspection passes the first time. Bathroom Remodeling in Highgrove covers cost ranges and the remodel sequence in detail.

Kitchen Remodeling in Highgrove
Kitchen remodeling in Highgrove usually means reworking a galley or closed-off kitchen inside a home built between 1955 and 1985. The original layouts were designed for a different era: no island, minimal counter space, and a wall separating the kitchen from the living area. Today’s homeowners want open sight lines, a working island, and appliances that don’t trip a breaker every time the microwave and toaster run together. That’s the job we do most. Holloway’s Kitchen Remodeling practice covers the full scope, and on this page we’ll walk through the specific sub-jobs Highgrove homes tend to need.
Cabinet and Countertop Replacement
Signs you need it
Doors are delaminating at the hinges, drawers stick or won’t close square, and the existing countertop has cracks, burns, or a seam that’s failed.
What it costs in Highgrove
Full cabinet and countertop replacement in Highgrove generally runs $14,000 to $38,000 depending on cabinet line and stone selection.
How we do it
We remove the old boxes and tops, level the base runs, install new cabinetry, template and install the counters, and finish with hardware and a punch-list pass.
Whole-Kitchen Renovation
Signs you need it
The layout doesn’t work, the plumbing and electrical are past their useful life, and you’re changing the kitchen’s footprint or opening a wall.
What it costs in Highgrove
A complete Highgrove kitchen renovation typically costs $36,000 to $82,000, including drywall, flooring, cabinetry, counters, and new electric runs.
How we do it
We demo the existing space, reframe the openings, run new plumbing and electrical, patch and level floors, install cabinets and counters, then finish with backsplash and trim.
What Kitchen Remodeling Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Cabinet and countertop replacement | $14,000 – $38,000 |
| Whole-kitchen renovation | $36,000 – $82,000 |
| Kitchen + interior finish package | $20,000 – $60,000 |
How long does a kitchen remodel take in Highgrove?
Most Highgrove kitchen remodels run six to ten weeks from demo to final. County inspections add days at predictable points, so we schedule them early and build the timeline around the inspector’s availability, not the reverse. Call (855) 617-6356 for a schedule based on your scope.
Will the county permit review delay my Highgrove kitchen project?
Riverside County plan check typically takes two to four weeks for a standard kitchen remodel with no structural changes. Alterations to load-bearing walls or major electrical service upgrades extend that. We submit complete drawings the first time, which keeps the review round to a single pass in most cases.
Brands We Service in Highgrove
We work with the major prefab and modular ADU manufacturers, including Abodu, Cover, and Dvele, and we specify James Hardie fiber cement exteriors on most site-built and shed-conversion projects. See our brands for a full overview of what each one brings to a Highgrove lot.

Two things push pricing up in Highgrove more than anything else. First is septic capacity: when a detached ADU needs a leach field expansion or a new perc test, the civil work adds cost before any structure goes up. Second is the age of the existing utility runs. Kitchens in 1960s Highgrove homes frequently need a service panel upgrade to support the appliance load. We quote fixed pricing with no change orders, and every estimate is a written line-item document, not a verbal ballpark.

FAQs About ADU Company in Highgrove
Yes. We manage the drawing package, the Riverside County permit submittal, construction, and the inspection sequence as one scope. You’re not coordinating an architect, a contractor, and a permit expediter separately. One point of contact covers the whole job.
Most do. Riverside County requires permits for electrical, plumbing, and any structural changes, which covers nearly every kitchen remodel we touch. Cabinet-only replacement with no utility work can sometimes skip permits, but we’ll tell you honestly which path applies to your scope before any work begins.
We do, and we’re familiar with the county’s septic review layer. For a kitchen or bathroom remodel, septic capacity rarely blocks the project. For a detached ADU on a septic lot, capacity can shape the size and placement of the unit. We’ll flag that early so you’re not surprised later.

What Highgrove Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Cole Schaefer"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."
— Heather Reed"Every invoice was tied to a completed milestone, so I always knew what I was paying for."
— Justin Kim
