ADU Company in Highgrove, CA
Kitchen remodeling in Highgrove usually means working inside a 1950s to 1970s ranch home where the original footprint, plumbing, and electrical were never designed for modern layouts. These projects regularly involve removing load-bearing walls between cramped kitchens and dining rooms, rerouting galvanized supply lines, and upgrading panels that have not been touched in forty years. Highgrove’s unincorporated status also changes the permit path, and we’re familiar with how Riverside County handles those inspections. Call (877) 752-4191 to talk through your kitchen with someone who knows this specific housing stock.
Why Highgrove Homes Are Different
Most Highgrove kitchens sit inside single-story ranch homes built between the 1950s and 1970s, on lots that are larger than what you find in neighboring Grand Terrace or Colton. That layout creates real opportunity: widening a kitchen into a former dining alcove, converting a detached garage, or extending the back wall is often structurally and legally possible. But the same age that gives these homes character also brings predictable problems. Cast iron drain lines, undersized 100-amp panels, and original slab foundations all influence what a remodel can do and what it will cost. Some properties still run on septic, which matters when we move or add plumbing. And because Highgrove is unincorporated, projects go through Riverside County rather than a city planning desk. That can allow square footages and setbacks that incorporated cities would reject, but it also means county reviewers look carefully at flood zone maps, non-permitted prior work, and lot drainage before anything gets approved. We’ve learned to check those boxes early so a kitchen remodel does not stall at the permit counter.
Our Main Highgrove Services
Two services account for most of the calls we take from Highgrove homeowners. Both benefit from the same approach: brand-agnostic product selection, county-level permit experience, and one team accountable from start to finish.
ADU Builders in Highgrove
Highgrove’s large lots and older ranch homes make it one of the more interesting ADU markets in Riverside County, but the unincorporated setting adds a layer most builders miss. Properties can sit in flood zones, rely on septic or shared wells, or carry non-permitted garage conversions that must be legalized before the county will approve a new unit. We work through those questions before recommending a platform, whether that is a Plant Prefab panelized unit, a Tuff Shed-based conversion, or a custom build with James Hardie exteriors. ADU Builders in Highgrove covers the full process, including utility planning and county submittals.
Bathroom Remodeling in Highgrove
Bathrooms in mid-century Highgrove homes were built small, often five by eight feet with a single vanity and a tub-shower combination. Remodeling here usually means stealing space from an adjacent closet or hallway, replacing cast iron drains, and correcting ventilation that was never adequate for the semi-arid valley’s hot summers. We handle the full scope in-house, which matters because moving a toilet or shower line in a slab foundation is not a job to hand off between contractors. Bathroom Remodeling in Highgrove walks through what is possible in this housing stock.

Kitchen Remodeling in Highgrove
Kitchen remodeling in Highgrove is not a cosmetic refresh in most of these homes. The original kitchens were built small, closed off from living space, and wired for a different era of appliances. Opening a wall, moving a sink run, or adding a range hood often triggers electrical and plumbing upgrades that a general contractor would treat as change orders we plan for from the first walkthrough. Highgrove’s unincorporated county review process also means setbacks, septic setbacks, and existing non-permitted conditions get checked before any cabinets are ordered. We coordinate that entire sequence, from the first county conversation to the final backsplash, so homeowners are never left managing subcontractors. For the broader service picture, see Kitchen Remodeling.
Full-Layout Reconfiguration
Signs you need it
The kitchen is walled off from the living room, the sink faces a wall, and there is no island or peninsula but plenty of unused square footage in an adjacent room.
What it costs in Highgrove
In Highgrove, a full-layout reconfiguration that removes a wall, relocates plumbing and electrical, and opens the kitchen to living space typically runs from $55,000 to $95,000 depending on beam length, panel capacity, and county-required upgrades.
How we do it
We confirm which walls are load-bearing, spec the beam and temporary shoring, pull the county permit, reroute plumbing and electrical, install new flooring and drywall, and finish with cabinetry, counters, and trim.
Mid-Century Galley Refresh
Signs you need it
The kitchen still works but feels dated, with worn laminate counters, original cabinets, and a single overhead light that leaves the workspace dark.
What it costs in Highgrove
A mid-century galley refresh in Highgrove, keeping the existing footprint but replacing cabinets, counters, lighting, and appliances, generally falls between $28,000 and $45,000.
How we do it
We preserve the footprint, replace cabinet boxes and faces, install new stone or quartz counters, add under-cabinet and overhead lighting, and upgrade the range and hood to modern code.
What Kitchen Remodeling Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Full-layout reconfiguration | $55,000 – $95,000 |
| Mid-century galley refresh | $28,000 – $45,000 |
| Appliance and finish upgrade (same footprint, no wall changes) | $18,000 – $32,000 |
How long does a kitchen remodel take in Highgrove?
Most Highgrove kitchen remodels take six to ten weeks from demolition to final inspection. County permit review adds one to three weeks depending on current Riverside County workloads and whether existing non-permitted work needs correction first. Call (877) 752-4191 to map your timeline.
Will the price change once the work starts?
No, because we write fixed, line-item quotes after the permit review identifies what the county will require. If we uncover a hidden cast iron drain or an undersized panel, we address it during design, not mid-demolition. Call (877) 752-4191 for a written estimate.
Brands We Service in Highgrove
We work with Plant Prefab panelized systems, Abodu’s turnkey ADU line, and James Hardie fiber cement exteriors, with Tuff Shed-based conversion pathways for lots where full custom is not the right spend. Local supplier access in the Inland Empire keeps turnaround predictable. See our brands for details on each platform.

FAQs About ADU Company in Highgrove
We can typically schedule the first walkthrough within two business days and begin design immediately after. County permit review is the variable part, and Riverside County’s current ADU and remodel review times often run longer than neighboring incorporated cities. Call (877) 752-4191 to get on the schedule.
Yes. Because Highgrove is unincorporated, all structural, plumbing, electrical, and ADU work goes through Riverside County rather than a city building department. The county also checks flood zone maps, septic system capacity, and existing non-permitted work, which we identify before submittal so the review moves faster.
Yes, and it is a standard part of our Highgrove work. A new ADU or a kitchen remodel that adds plumbing often requires a septic system evaluation from Riverside County to confirm the existing system can handle the added load. We build that step into the estimate and the schedule from the first conversation.
