ADU Company in Portola Hills, CA
Kitchen remodeling in Portola Hills means working with 1980s and 1990s Mediterranean-style homes on terraced hillside lots, where the original layouts were built for a different era of living. We’re Home Base ADU Builders, and we handle kitchens, bathrooms, and ADUs as a single contractor, which matters when you’re coordinating a hillside build or renovation. If you’re weighing a kitchen remodel alongside an ADU, call (866) 403-9834 for a free estimate, and we’ll walk through what’s actually possible on your specific lot.
Why Portola Hills Homes Are Different
Portola Hills sits in the Santa Ana Mountain foothills, above the marine layer that keeps coastal Orange County mild. That means hotter summer afternoons and real Santa Ana wind exposure, so any indoor project needs to account for cooling loads and fire-conscious material choices. Most of the housing stock went up in the 1980s and 1990s as Spanish and Mediterranean tract homes – stucco exteriors, tile roofs, two-story plans – on graded lots with limited flat yard space. Many foundations are post-tension slabs or raised systems cut into the slope.
The HOA layer here is unusually active for Orange County. Most tracts have CC&Rs governing exterior changes, view corridors, and hillside easements. A kitchen remodel that moves a window, changes a vent location, or expands an exterior wall can trigger architectural review just as quickly as an ADU would. That’s not a reason to avoid the work. It’s a reason to plan the submittal correctly the first time.
Our Main Portola Hills Services
Two services generate most of our calls from Portola Hills homeowners: ADU construction and bathroom remodeling. Both are handled by our team directly, and both get the same upfront, line-item pricing.
ADU Builders in Portola Hills
ADUs on Portola Hills lots are constrained less by the City of Lake Forest setback rules than by HOA view-and-slope easements. Nearly every build we’ve planned here has involved architectural review submittals and sightline studies before a permit was even applied for. Attached conversions and garage conversions usually make the most sense given the limited flat rear-yard area. You can read the full breakdown on our ADU Builders in Portola Hills page.
Bathroom Remodeling in Portola Hills
Bathrooms in these 1980s-era homes tend to share walls with bedrooms and closets, with original fiberglass surrounds and dated tile layouts. Hillside drainage matters too – we check venting and subfloor condition before touching finish work. For specifics on scope and cost, see Bathroom Remodeling in Portola Hills.

Kitchen Remodeling in Portola Hills
Kitchen remodeling in Portola Hills typically means opening up a closed-off 1980s floor plan while working around load-bearing walls, hillside foundation constraints, and HOA rules that can affect exterior venting and window changes. The original kitchens in this tract housing are small by current standards, often with soffits, fluorescent lighting, and a peninsula that blocks the natural path through the house. Our Kitchen Remodeling process covers layout, permits, cabinetry, countertops, and finish work under one contract.
Full Kitchen Gut
Signs you need it
Water-damaged cabinet bases, failed tile countertops, inadequate wiring, or a layout that hasn’t worked since the day you moved in.
What it costs in Portola Hills
A full gut remodel in Portola Hills typically runs $65,000 to $115,000, depending on layout changes, cabinet grade, and whether we’re moving plumbing or gas lines.
How we do it
We remove everything to studs, address any subfloor or wall damage, then rebuild with new electrical, plumbing, insulation, drywall, cabinetry, counters, and finishes.
Cabinet Refacing
Signs you need it
Your cabinet boxes are still sound but the doors and drawer fronts are worn, faded, or outright dated.
What it costs in Portola Hills

How we do it
We measure and order replacement fronts in your chosen material and finish, then install new hardware, hinges, and drawer glides without disturbing the existing cabinet boxes.

What Portola Hills Customers Say
"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Luis Garcia"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."
— Robert Hayes"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Colleen Pruitt
