ADU Company in Highgrove, CA
Kitchen remodeling in Highgrove means working with the housing stock that defines this unincorporated Riverside County community: older, modest single-family homes on long lots where the original kitchens were built for a different era. We’re Sapphire ADU Builders, and while ADUs are our specialty, complete kitchen delivery is how we finish those units without handing you off to a second contractor. Highgrove’s hot inland climate also shapes how we approach kitchen work, from ventilation choices to materials that won’t warp or fade under months of direct sun. Call (855) 594-0655 for a free estimate on your Highgrove kitchen project.
Why Highgrove Homes Are Different
Highgrove’s 92313 sits entirely in unincorporated Riverside County, which changes the remodeling and building conversation from day one. There is no city planning counter, no local design review board, and no city-issued business license requirement. Every permit, from a kitchen remodel to a full detached ADU, goes through Riverside County’s building department. That single jurisdiction can feel simpler, but it also demands precision on submittals because there is no local front-counter shortcut when a correction is needed.
The housing stock itself pushes projects in a clear direction. Homes here tend to be older, modest single-family detached structures on low-density lots with real side and rear yards. That means detached builds and ground-up work make more sense than squeezing additions onto tight urban footprints. The long, flat lots also keep setback and lot-coverage checks straightforward, which is exactly what you want when you’re planning a kitchen expansion or a backyard unit. For kitchen work specifically, we regularly open walls in Highgrove homes and find framing layouts and plumbing runs that predate modern code expectations. Knowing that going in changes how we quote and how we schedule.
Climate is the third factor. Highgrove gets hot, with long summers that punish cheap materials. We specify finishes, cabinet hardware, and ventilation with that heat in mind, and we think about window placement and shading even on interior remodels because the sun here doesn’t stop at the exterior wall.
Our Main Highgrove Services
Most Highgrove homeowners call us about two things: building a backyard ADU, or remodeling a bathroom or kitchen inside the main house. Here’s what each looks like in this community.
ADU Builders in Highgrove
Because Highgrove is unincorporated, ADU projects here answer only to Riverside County’s ADU ordinance and county building department. No city planning layer, no local design review. That’s a real advantage for homeowners, and it’s one reason detached ADUs on Highgrove’s long lots are the natural fit. We’ve served Highgrove since 2015 and have worked through every county submittal curveball this area can produce. From foundation to finished kitchen, one team owns the whole project. ADU Builders in Highgrove is where you’ll find the full breakdown of how our process works here.

Bathroom Remodeling in Highgrove
Bathroom remodels in Highgrove’s older homes often involve moving plumbing that hasn’t been touched since the house was built, which is exactly the kind of work that surprises general contractors but doesn’t surprise us. We handle bathroom remodeling as part of complete ADU delivery and as standalone projects in the main house. The dry heat means we pay attention to ventilation and moisture control so finishes last. Bathroom Remodeling in Highgrove covers the full scope, pricing, and process for this area.

Kitchen Remodeling in Highgrove
Kitchen remodeling in Highgrove starts with a simple reality: most kitchens in this community were built in homes from the 1960s through the 1980s, and they were designed for a household that cooked less, stored less, and gathered less than families do now. The heat of the Inland Empire makes a poorly ventilated kitchen feel worse than it should, and aging plumbing and electrical rarely meet what a modern kitchen asks of them. We remodel kitchens as part of complete ADU delivery and as standalone projects in Highgrove homes, which means the same team that frames your walls also installs your cabinets, tile, counters, and appliances. No hand-offs, no second contractor, no gaps between trades. If you’re weighing a kitchen project alongside a larger property plan, our Kitchen Remodeling hub lays out the full scope of what we do.
Full Kitchen Gut and Rebuild
Signs you need it
Your kitchen has original cabinets, a floor plan that traps you in one corner, or plumbing and electrical that can’t support two appliances at once.
What it costs in Highgrove
A full kitchen gut and rebuild in Highgrove typically runs $31,000 to $71,000 depending on finish level and layout changes.
How we do it
We demo to studs, reroute plumbing and electrical for the new layout, rebuild walls and openings, install drywall and flooring, then set cabinets, counters, tile, appliances, and trim.
Kitchen Flooring and Cabinet Replacement
Signs you need it
Your cabinets are structurally sound but dated, and the floor is worn, uneven, or impossible to clean where the old layout left gaps.
