ADU Company in Riverside, CA
Casita ADU Builders has served Riverside since 2013, and the call we get most often starts with a kitchen that no longer works for the household – cramped ranch-house layouts, exhausted 1970s cabinetry, and appliances that can’t keep up with a Riverside summer. We specialize in ADU construction, with in-house kitchen and bathroom remodeling that finishes every interior detail under one contract. From prefab delivery to finished kitchen and bath, one team handles it all. Call (877) 658-7475 for a free estimate.
Why Riverside Homes Are Different
Riverside’s ADU and remodeling work happens in infill backyards, not new subdivisions. The typical project sits behind a mid-century ranch house on a 7,000-square-foot lot in Arlington, La Sierra, or Magnolia Center, where the constraint is usually lot coverage, setbacks, and utility routing through a yard never designed for a second dwelling. The housing stock leans heavily toward 1950s-to-1970s single-story tract homes, many with attached two-car garages or detached rear garages facing alleys. Those older detached garages often sit on shallow or absent foundations, with aging electrical panels and undersized main service that need upgrading before an ADU can be fed.
Riverside’s inland climate changes the build math, too. Summer heat pushes well past 100°F, and Santa Ana winds arrive hot and dry. That means ADUs and interior remodels here need real cooling loads, deep roof overhangs, and fire-resistant detailing on wind-exposed walls – not the mild-coast assumptions that work in neighboring LA or Orange County. Alley-facing rear garages in the older central neighborhoods are a genuine advantage: many Riverside ADUs get vehicular access and utility routing from the alley instead of trenching through the main house’s backyard, which can cut site costs meaningfully compared to inland cities whose lots don’t back onto alleys.
Our Main Riverside Services
Two services dominate Riverside homeowner calls: ADU design and construction, and interior remodels that prepare the existing home or finish a new ADU. Here’s what each involves locally.
ADU Builders in Riverside
Riverside’s pro-ADU ordinance posture and the UC Riverside student-rental market keep detached units and garage conversions in steady demand. We work across all the leading prefab brands so you choose the right ADU, not just the one we happen to sell. Shed conversion, modular, or site-built, we match the build type to your lot, budget, and timeline. In older central Riverside, alley access and utility routing often decide whether a detached rear-garage conversion pencils out. ADU Builders in Riverside covers the full process.
Bathroom Remodeling in Riverside
Riverside bathrooms from the 1960s and 1970s come with original cast-iron drains, mud-set tile, and ventilation never sized for inland heat. Our in-house bathroom remodeling team handles the full interior finish on ADUs and remodels of the primary home alike, so the bath is completed under the same contract as the build. No handoffs, no gaps. Bathroom Remodeling in Riverside explains what we do and what it costs.

Kitchen Remodeling in Riverside
Kitchen remodeling in Riverside usually means opening a closed 1960s ranch kitchen into something functional for a household that’s grown, or building a full kitchen inside a new ADU where none existed. Many older Riverside homes have kitchens laid out for one cook, with limited counter space, original galvanized plumbing, and electrical service too small for modern appliances. Our in-house team handles the entire kitchen build-out, and since we specialize in ADUs, we’re the same crew that can finish a kitchen in your new unit without handing you off to a second contractor. Kitchen Remodeling is our core interior service, and Riverside’s specific conditions shape how we price and build every job.
Full Kitchen Remodel
Signs you need it
Your Riverside kitchen has original 1960s or 1970s cabinets, one narrow counter, and electrical that trips when the microwave and toaster run together.
What it costs in Riverside
A full kitchen remodel in Riverside typically runs $25,000 to $55,000 depending on finish level, layout changes, and whether we’re upgrading the main panel to feed the new appliance load.
How we do it
We confirm the existing electrical and plumbing conditions, finalize cabinet and counter selections, then handle demolition, rough-in, drywall, flooring, cabinet install, counter fabrication, and appliance hookup as one crew under one contract.
ADU Kitchen Build-Out
Signs you need it
You’re building a detached ADU or converting a garage in Riverside, and the unit needs a complete kitchen designed for a small footprint with real cooking capability.
What it costs in Riverside
A compact ADU kitchen build-out in Riverside typically runs $15,000 to $30,000, with the higher end including full-height cabinetry, stone counters, and a gas or induction range wired and plumbed from scratch.
How we do it
We design the kitchen around the ADU’s floor plan and utility locations, route plumbing and electrical from the main service, then install cabinetry, counters, appliances, and backsplash as part of the overall build schedule.
What Kitchen Remodeling Costs in Riverside
| Item | Typical range in Riverside |
|---|---|
| Full kitchen remodel | $25,000 – $55,000 |
| ADU kitchen build-out | $15,000 – $30,000 |
| Cabinet refacing and counter replacement | $8,000 – $18,000 |
How long does a kitchen remodel take in Riverside?
A full kitchen remodel in Riverside usually runs six to ten weeks from demo to final walkthrough. ADU kitchen build-outs follow the unit’s construction schedule, so timing depends on whether we’re doing a prefab delivery or a site-built or shed-conversion project.
Will my Riverside kitchen remodel trigger a panel upgrade?
Often, yes. Many 1950s-to-1970s Riverside homes have 100-amp panels that cannot safely feed a modern kitchen plus an ADU. We can assess this during the estimate, so there are no surprises once work starts.
Brands We Service in Riverside
We’re brand-agnostic by design. In Riverside, homeowners choose from Abodu, Cover, and other leading prefab manufacturers, plus Tuff Shed for shed-conversion ADU projects. Exteriors use James Hardie fiber-cement, a finish built to weather decades and still look the part. See our brands for the full roster.

What Riverside Customers Say
"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."
— Aisha Prince"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Maria Martinez"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."
