ADU Company in Sunnyslope, CA
Kitchen remodeling in Sunnyslope means working with homes built mostly in the 1950s through 1970s, where floor plans were closed off, electrical panels are often undersized, and the intense Jurupa Valley heat puts real strain on ventilation and cooling. Holloway ADU Builders handles the full scope, from moving walls to specifying finishes that stand up to 100°F summers without fading or warping. If you’re planning an ADU and want the interior finished to match, one team can carry both projects. Call (855) 617-6356 to talk through your lot and goals.
Why Sunnyslope Homes Are Different
Sunnyslope is an unincorporated Riverside County island wrapped around the City of Jurupa Valley, so nearly every ADU here is a county project, not a city one. Plans go through Riverside County’s building department and fire authority while utilities and access issues sit with neighboring Jurupa Valley. That jurisdictional split catches a lot of contractors off guard. We know the county/Jurupa Valley boundary dance, and we design for it from day one.
The housing stock itself changes what’s possible. Many Sunnyslope lots trace back to rural-suburban subdivisions with real acreage and a horse-keeping history. That means detached ADUs and converted garages are far more common here than in denser Riverside neighborhoods, where lot coverage kills the idea before it starts. But it also means we regularly find unpermitted prior additions and older utility infrastructure that needs upgrading before a second dwelling can pull power, water, and sewer. Homes in the 92509 ZIP carry decades of ad hoc fixes, and part of our job is untangling that so the county inspector sees a clean file.
Climate shapes the material choices too. Sunnyslope sits in the Jurupa Valley basin, where summer days routinely cross 100°F and Santa Ana winds push extreme fire-weather patterns through the foothills. ADUs here need serious cooling loads, reflective roofing, and ember-resistant venting on anything near the wildland edge. A cute prefab unit without the right venting simply won’t pass county fire review, and a kitchen without proper exhaust gets miserable by July.
Our Main Sunnyslope Services
Sunnyslope homeowners call us about two things more than anything else: building an ADU on their county lot, and remodeling bathrooms inside older homes or as part of finishing a new ADU. Each has its own Sunnyslope page with the full detail.
ADU Builders in Sunnyslope
Building an ADU in Sunnyslope means navigating the county/Jurupa Valley boundary line on utilities, setbacks, and fire review. We compare prefab, modular, and site-built options against your specific lot, because a horse property with septic considerations needs a different answer than a tighter 1950s parcel. From Abodu to Tuff Shed conversions, we’ve navigated every type of ADU project. ADU Builders in Sunnyslope covers the full scope, including what the county requires before you even design.
Bathroom Remodeling in Sunnyslope
Older Sunnyslope homes carry original plumbing that was never sized for modern fixtures, and many bathrooms we open up reveal cast-iron drain lines and undersized vent stacks. When the remodel is part of an ADU interior finish, the work doubles: rough-in, waterproofing, and fixture selection that matches the rest of the dwelling. Bathroom Remodeling in Sunnyslope walks through the common scope for 92509 homes, from full tear-outs to ADU bathroom builds.

Kitchen Remodeling in Sunnyslope
Kitchen remodeling in Sunnyslope usually means opening up a closed-off galley layout in a home built between the 1950s and 1970s, and doing it before the summer heat makes the job site unbearable. We handle the structural work, the cabinet and counter installation, and the Kitchen Remodeling finishes that tie into an ADU’s interior when the two projects run together. Older 92509 homes often need electrical service upgrades and better exhaust ventilation before a new kitchen can function the way it should. Here are the sub-jobs we see most.
Cabinet Replacement
Signs you need it
Face frames are pulling away from the boxes, drawer slides bind, or water damage has swollen the bases under the sink.
What it costs in Sunnyslope
Cabinet replacement in Sunnyslope typically falls between $12,000 and $28,000 depending on linear footage, door style, and whether boxes get reused or fully replaced.
How we do it
We verify the existing boxes, demo carefully to preserve walls and flooring, then install new cabinets with reinforced mounting cleats and leveled runs before counters and plumbing reset.
Countertop and Backsplash Installation
Signs you need it
Laminate is delaminating, tile grout is cracking from decades of heat expansion, or the existing counter can’t support a heavier stone surface.
What it costs in Sunnyslope
Countertop and backsplash installation in Sunnyslope runs $5,000 to $12,000 depending on material, edge profile, and how much demo is required.
How we do it
We template after the new cabinets are set, fabricate off-site, then install stone or solid-surface pieces with mechanical fasteners and sealed seams, followed by a waterproofed backsplash.
Full Layout Reconfiguration
Signs you need it
The kitchen is closed off from the dining area, the work triangle spans more than 9 feet, or the current footprint wastes the lot’s natural light.
What it costs in Sunnyslope
Full layout reconfiguration in Sunnyslope runs $45,000 to $80,000 depending on structural scope, utility relocations, and finish level.
How we do it
We draft the new layout against your lot and home’s bearing points, permit through Riverside County, then sequence demo, plumbing and electrical rough-in, drywall, and finish trades in one continuous push.

How long does a kitchen remodel take in Sunnyslope?
Most Sunnyslope kitchen remodels run six to twelve weeks from demo to final walkthrough. Larger reconfigurations that involve structural work or utility upgrades add two to four weeks, and county inspection timing can shift the schedule either direction. Call (855) 617-6356 to get a realistic timeline for your specific scope.
Will the price change once work starts?
Not unless you change the scope or we find something behind the walls that has to be corrected for code compliance, which does happen in older Sunnyslope homes. We write line-item quotes with fixed allowances for the specified finishes, and any discovered condition gets priced and approved by you before we proceed. Call (855) 617-6356 for a written quote.

What pushes price up in Sunnyslope is usually older utility infrastructure: undersized panels, cast-iron drains, or septic-to-sewer questions on horse properties that surface once we open the walls or pull county records. The upfront-price promise matters here because so many Sunnyslope homes carry hidden conditions from decades of ad hoc additions. We quote line-item, fix the allowance in writing, and don’t hit you with a change order unless you change the scope first.

FAQs About ADU Company in Sunnyslope
Yes. Since Sunnyslope is unincorporated Riverside County, every permitted kitchen remodel goes through the county building department, not Jurupa Valley’s. We handle the drawings, the submittal, and the inspections from start to final sign-off. Call (855) 617-6356 to check whether your specific scope needs a permit.
Yes, that’s the model we’re built around. One team carries the ADU structure and the interior finish work, including kitchens and bathrooms, so you’re not coordinating two contractors on the same Sunnyslope lot. This matters especially when the ADU kitchen and the main house kitchen are both on the same schedule.
We cover the entire 92509 ZIP, including all the county-island parcels wrapped around Jurupa Valley. If your property sits on the boundary, we’ll verify which jurisdiction controls your permit path before we quote, so there are no surprises at submittal. Call (855) 617-6356 to confirm your lot.

What Sunnyslope Customers Say
"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Cole Schaefer"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 Reed"Every invoice was tied to a completed milestone, so I always knew what I was paying for."
— Justin Kim
