ADU Company in Highgrove, CA
Kitchen remodeling in Highgrove often means working inside a 1960s or 1970s ranch home where the original layout, wiring, and plumbing are still in place. The half-acre lots give homeowners room to expand a footprint, but the county’s unincorporated status means any structural change has to clear Riverside County planning review, not a city counter. That makes kitchen work here as much about paperwork and existing-condition detective work as it is about cabinets and counters. We handle both sides of that equation. Call (844) 934-0236 for a free estimate.
Why Highgrove Homes Are Different
Highgrove sits in unincorporated Riverside County, wedged between Riverside and Moreno Valley, and that changes how every permit gets pulled. There is no Highgrove building department. ADU and kitchen projects run through County of Riverside Planning and Building & Safety, which means county setbacks, fire-hazard review on hillside lots in the Box Springs foothills, and a records process that digs into every square foot of existing structure. We regularly find pre-1980 unpermitted patio enclosures, garage conversions, or room additions that the county will want reconciled before it approves new work. That is the unglamorous part of the job, and it is the part that determines whether a project takes eight weeks or eight months.
The housing stock is mostly single-story ranch homes built between 1955 and 1980 on large lots, many half an acre or more. Detached garages sit at the back of the parcel. Sheds, patios, and carports got enclosed over the decades, often without permits. For a kitchen remodel, that means we are frequently correcting substandard wiring, undersized circuits, or plumbing that was never inspected. The county will want those items brought to current code before it signs off on the new kitchen. We plan for that from day one, so the homeowner is not blindsided mid-project.
Climate is the other factor. Summer highs in Highgrove routinely pass 105°F, and afternoon winds come through the foothills with enough force to matter during exterior wall work. A kitchen remodel here means specifying ventilation that actually moves hot air, insulation that holds up to sustained heat, and window or door placements that do not turn the west-facing wall into an oven. Those are not luxury upgrades; they are the difference between a kitchen that works and one that fights the climate.
Our Main Highgrove Services
Highgrove homeowners call us about two things most often: building an ADU on the back half of the lot, and remodeling the bath inside the main house or the new unit. Both run through the same county permitting process and the same contractor relationship.
ADU Builders in Highgrove
Detached ADUs make sense on Highgrove’s large lots, where a garage at the back of the parcel can become a legal rental unit or a place for aging parents. The catch is that many of those garages were built before 1980 and never brought up to code, and some lots have unpermitted additions the county will flag during ADU review. We work backward from the county’s requirements, reconcile what is there, then match the right build method to the lot. ADU Builders in Highgrove covers the full process from records research to final inspection.
Bathroom Remodeling in Highgrove
Original bathrooms in Highgrove’s ranch homes are small, typically a tub-shower combo, a single vanity, and a ventilation fan that has not worked since the 1990s. Adding a second bath or expanding the primary bath usually means moving drain lines through a slab foundation, which is straightforward but requires county inspection. We handle the permit, the plumbing, and the finish work. Bathroom Remodeling in Highgrove explains the process and what it costs on this side of Riverside County.

Kitchen Remodeling in Highgrove
Kitchen remodeling in Highgrove usually starts with a 1960s or 1970s layout that no longer matches how the household cooks, plus wiring and plumbing that predate modern code. The half-acre lots and ranch footprints give room to open the kitchen to a dining area or add a peninsula without a full addition. What the work requires is a contractor who understands County of Riverside permitting, fire-hazard review on hillside parcels, and the reality that many of these homes have unpermitted patio or garage enclosures the county will want addressed before it approves the kitchen permit. We plan for all of it. For more on our full process, see Kitchen Remodeling.
Full Gut Renovation
Signs you need it
The original 1960s or 1970s cabinets are failing, the layout walls are load-bearing masonry or aged framing, and the wiring is either ungrounded or overloaded by modern appliances.
What it costs in Highgrove
A full gut renovation in Highgrove typically runs $18,000 to $35,000 depending on whether structural changes, slab plumbing moves, or code corrections are required.
How we do it
We demo to the studs, correct the wiring and plumbing, reframe or reinforce any load paths, hang drywall, then install new cabinets, counters, flooring, and fixtures through the county inspection sequence.
Cabinet and Counter Replacement
Signs you need it
The cabinet boxes are swelling or the frames are sound but the doors, drawer slides, and countertops are worn out, and the layout actually works.
What it costs in Highgrove
Cabinet and counter replacement in Highgrove generally runs $8,000 to $18,000 depending on material grade, linear footage, and whether we need to match or replace any surrounding millwork.
How we do it
We remove the existing fronts and countertops, check the cabinet boxes for square and load, install new doors, hardware, and stone or quartz surfaces, and schedule the county inspection if any plumbing or electrical connections moved.
What Kitchen Remodeling Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Full gut renovation | $18,000 – $35,000 |
| Cabinet and counter replacement | $8,000 – $18,000 |
| Island addition (reframing included) | $7,000 – $15,000 |
Prices push upward in Highgrove when the county requires correction of unpermitted prior work, when the hillside lot triggers fire-hazard review on exterior wall openings, or when the slab plumbing has to be relocated. We quote a fixed price up front, and it does not change once work starts unless the county’s plan check reveals something the homeowner chose to hide at intake.
How long does a kitchen remodel take in Highgrove?
A full gut renovation typically runs 6 to 10 weeks in Highgrove. County plan check and the existing-permit reconciliation work on older parcels can add 2 to 4 weeks before demolition starts. Call (844) 934-0236 for a timeline specific to your property.
Will the county make me fix unpermitted work before my kitchen permit is issued?
Often yes. If a converted patio or enclosed garage is attached to the kitchen footprint, Riverside County will usually require it be legalized or removed as a condition of the new permit. We identify that risk during the first site visit, not after demolition. Call (844) 934-0236 for a free assessment.

We build and install from a curated set of manufacturers, including Plant Prefab, Tuff Shed, and Abodu, and we use James Hardie fiber-cement siding on most custom exterior work. See our brands for the full lineup and which ones fit Highgrove’s fire-hazard and heat conditions.

What Highgrove Customers Say
"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Malik Nash"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Steven Nguyen"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 Ackerman
