ADU Company in Highgrove, CA
Kitchen remodeling in Highgrove usually starts with a mid-century ranch kitchen that hasn’t been touched since the Nixon administration: low ceilings, fluorescent soffits, and a layout built around a single cook’s workflow. We’re Guest House ADU Builders, and we handle Highgrove kitchen remodels from the first measurement to the final cabinet pull, on lots where the house is older, the electric panel is maxed out, and the county permit path runs through Riverside rather than a city counter. Call (833) 863-7015 for a free estimate.
Why Highgrove Homes Are Different
Highgrove is unincorporated Riverside County territory, so permits, setbacks, and inspections go through Riverside County’s Planning Department and Building & Safety rather than a city hall. That’s not a small detail. A Highgrove homeowner adding square footage or moving a kitchen wall deals with county zoning rules, and on the older lots along Center Street and Mt. Vernon Avenue, that can also mean septic and water-capacity questions before construction starts. The housing stock skews mid-century and older: single-story ranch and stucco-over-framed homes on generous 7,000 to 10,000-plus square foot lots, many with detached garages, workshops, and unpermitted additions that complicate kitchen work when walls conceal old wiring.
The climate adds another layer. Highgrove sits in the warm inland Riverside basin below the Box Springs Mountains. Summer afternoons push past 100°F, and Santa Ana winds can rip through in fall. A kitchen remodel here has to account for heat gain from west and southwest-facing walls, so we pay attention to window placement, ventilation, and appliance heat output. Winter frost is occasional, but when the summer monsoon drops quick heavy rain, roof drainage and grading around kitchen bump-outs matter. These are the conditions we’ve worked in since 2011.
Our Main Highgrove Services
Most Highgrove homeowners call us about two things: adding an ADU to a big lot, or upgrading an aging house that needs a kitchen or bath brought into this decade. Both run through the same county permit system, and both benefit from one contractor who knows the local path.
ADU Builders in Highgrove
Highgrove’s large lots and unincorporated county rules make it a natural ADU market, but the process has Highgrove-specific wrinkles: septic and perc testing through Riverside County Environmental Health on older parcels, county setback reviews, and water-service checks through Highgrove Mutual or successor systems. We’ve built detached units, garage conversions, and legalization cleanups on Highgrove properties, working across prefab brands like Abodu and Dvele plus site-built designs. More detail is on our ADU Builders in Highgrove page.
Bathroom Remodeling in Highgrove
Many Highgrove bathrooms sit inside mid-century homes with cast-iron drain lines and tight footprints. A bathroom remodel here often means working around unpermitted past additions, old galvanized supply pipes, and county building inspections. We handle full gut-and-replace work, walk-in shower conversions, and accessible bathroom updates, all through one team. See the specifics on our Bathroom Remodeling in Highgrove page.

Kitchen Remodeling in Highgrove
A Highgrove kitchen remodel usually means taking a 1960s or 1970s galley or U-shaped kitchen, opening it toward a dining area, replacing the soffits and fluorescent lighting, and bringing the electrical service up to what modern appliances actually draw. Many of these homes have original 100-amp panels and aluminum branch wiring, so the work starts behind the walls before the cabinets go in. This is core Kitchen Remodeling work, but with Highgrove’s county permit path and older stock, we sequence electrical, plumbing, and structural changes so the county inspection doesn’t stall the job.
Full Kitchen Gut and Replace
Signs you need it
Your cabinets are particleboard with delaminating doors, the layout traps two people at a pinch-point, and the countertops show scorch marks and water damage.
What it costs in Highgrove
In Highgrove, a full kitchen gut and replace typically runs $25,000 to $45,000 depending on cabinet grade, countertop material, and how much electrical and plumbing work the county inspection requires.
How we do it
We remove the old kitchen to the studs, rerun or upgrade electrical and plumbing as needed, patch and level the walls, then install new cabinets, counters, flooring, lighting, and appliances in a sequence that passes Riverside County building inspections at rough-in and final.
Cabinet Refacing and Countertop Replacement
Signs you need it
Your cabinet boxes are solid wood and still square, but the doors are dated, the hinges sag, and the laminate counters are chipped and stained beyond repair.
What it costs in Highgrove
Cabinet refacing with new doors, drawer fronts, hardware, and a replacement countertop generally runs $8,000 to $18,000 in Highgrove homes.
How we do it
We measure the existing boxes, order matched doors and fronts, reface the face frames and side panels, install new hardware and hinges, then template and set the new countertop material on site.
What Kitchen Remodeling Costs in Highgrove
| Item | Typical range in Highgrove |
|---|---|
| Full kitchen gut and replace | $25,000 – $45,000 |
| Cabinet refacing and countertop replacement | $8,000 – $18,000 |

Costs move higher in Highgrove when the county requires panel upgrades, when walls conceal old wiring that must be replaced, and when permits add extra inspection cycles. We quote a fixed price before work starts, and that number doesn’t change unless you change the scope.
How long does a full kitchen remodel take in Highgrove?
Plan on six to ten weeks for a full gut-and-replace kitchen in Highgrove. County inspection scheduling and the age of the home’s wiring and plumbing are the two things that most often stretch the timeline past the initial estimate.
Do you pull the county permits for a Highgrove kitchen remodel?
Yes. We pull the Riverside County building permits, schedule the inspections, and keep the job moving through rough-in and final. You will not be asked to pull your own permits. Call (833) 863-7015 for a specific quote.

What pushes prices up in Highgrove is usually not the finish work. County-required septic and perc testing on older parcels, electrical service upgrades on original 100-amp panels, and unpermitted additions that must be legalized before new work can pass inspection are the line items that move a Highgrove budget. We give a written fixed-price quote up front, with no change orders unless you change the scope.

FAQs About ADU Company in Highgrove
For kitchen and bath remodels, we can usually get the permit application filed within two to three weeks of a signed contract, depending on Riverside County’s current review queue. ADU projects take longer because the county septic and zoning review adds weeks before construction can start.
Most Highgrove properties are not in a formal HOA, but some newer pockets have deed restrictions or mutual water company requirements. We check both before the permit goes in. County permits are always required for structural, electrical, and plumbing work.
Yes, and it is often the cleaner path. One project, one permit set, one contractor for both scopes. We bundle kitchen and bath work with ADU construction so the county inspections overlap and the site work happens once. Call (833) 863-7015 to schedule your free estimate.
