ADU Company in San Bernardino, CA
Kitchen remodeling in San Bernardino usually means working inside a 1950s or 1960s single-story tract home where the original footprint was built for a different era: smaller appliances, fewer circuits, and no thought of an open floor plan. Most of the kitchens we see in ZIPs 92404 and 92405 still carry original 60-amp electrical service, galvanized supply lines, and cabinetry that outlived its usefulness decades ago. We’re Sunstone ADU Builders, an ADU specialist that also handles kitchen and bathroom remodeling, typically scoped to ADU interiors or companion remodels on the primary residence. If you’re planning a rental-ready ADU or bringing your main kitchen into this century, call us at (855) 949-1913 for a free estimate.
Why San Bernardino Homes Are Different
San Bernardino’s housing stock skews heavily toward post-WWII single-story stucco tract homes on generous lots. That’s good news for anyone adding a detached ADU or expanding a kitchen footprint, but the age of these properties brings specific challenges. Many homes built before 1970 still run on 60-amp electrical panels, which cannot support a modern kitchen with an induction range, double oven, and dedicated circuits for small appliances. Galvanized plumbing is common and often pinholed or corroded where it enters the kitchen. Sewer lines in older neighborhoods are shallow, which matters when you’re moving a sink or adding a new one in an ADU.
Climate shapes the work, too. San Bernardino regularly tops 100°F in summer, and homes at the base of the San Bernardino Mountains sit in wildfire interface zones where fire-resistant construction matters. For kitchens, that means venting that can handle real heat, insulation that keeps cooling bills sane, and materials that won’t warp or delaminate when the Santa Anas blow through. The neighborhoods around 92404 and 92405, with their narrow lots and detached garages, frequently convert those garages into ADUs with compact kitchens and full bathrooms. That conversion almost always triggers an electrical service upgrade from 60 amps to 200 amps before the first cabinet goes in.
Our Main San Bernardino Services
Two services dominate the calls we get from San Bernardino homeowners: building ADUs and remodeling bathrooms inside those ADUs or in the primary home. Each has its own dedicated San Bernardino page, so here’s a quick look at what each job involves locally.
ADU Builders in San Bernardino
San Bernardino’s large stock of post-WWII single-story tract homes on generous lots makes the city a natural fit for detached ADUs. Homeowners along the older corridors are adding units for multigenerational living and rental income under California’s streamlined ADU laws. But the city’s many pre-1970 properties often trigger mandatory upgrades before framing begins: 200-amp electrical service, sewer line updates, and fire-resistant construction in high-fire zones. We’re authorized to build and install prefab ADUs from Abodu, Cover, and Tuff Shed-style structures, or go traditional stick-built, whichever fits your site. Read the full breakdown at ADU Builders in San Bernardino.
Bathroom Remodeling in San Bernardino
Older San Bernardino homes often have one bathroom on the original floor plan, and it shows its age: cast-iron drains, a tub that’s lost its finish, and a single vanity with no storage. When we build an ADU, we finish the bathroom in-house under the same contract, but we also remodel primary-home bathrooms when the scope warrants it. San Bernardino’s hard water is a factor in fixture selection and water-line replacement in pre-1970 homes. See what’s typical for this market at Bathroom Remodeling in San Bernardino.

Kitchen Remodeling in San Bernardino
Kitchen remodeling in San Bernardino means solving the problems baked into 1950s and 1960s tract homes: too few circuits, original galvanized plumbing, and layouts that were designed for a 30-inch range and a single overhead light. The payoff is a kitchen that can handle a modern family or a rental-ready ADU without tripping breakers every time the air conditioner cycles on. We scope kitchens alongside ADU construction and as standalone remodels on primary homes. For a broader look at our kitchen work, visit Kitchen Remodeling.
Full Kitchen Remodel
Signs you need it
Your kitchen still has its original cabinet layout, counters, and single circuit, and using the microwave and toaster together trips the breaker.
What it costs in San Bernardino
A full kitchen remodel in San Bernardino typically runs $32,000 to $58,000 depending on cabinet grade, countertop material, and how much electrical and plumbing work the old house needs.
How we do it
We start with a site walk to check the panel, plumbing, and framing, then produce drawings, pull permits, and build the project: demo, rough electrical and plumbing, drywall, cabinets, counters, tile, and finish plumbing.
Kitchen Refresh
Signs you need it
The cabinets are sound but dated, the countertop is worn, and you want a newer look without moving walls or replacing every appliance.
What it costs in San Bernardino
A kitchen refresh in San Bernardino comes in around $16,000 to $27,000 for refinishing or refacing cabinets, new counters, a tile backsplash, and updated fixtures.
How we do it
We strip and reface or refinish the existing cabinet boxes, install new countertops and backsplash, swap faucets and lighting, and repaint, all with minimal disruption to the rest of the house.
ADU Kitchen Build-Out
Signs you need it
You’re adding a detached ADU in San Bernardino and need a compact, code-compliant kitchen that makes the unit genuinely rentable.
What it costs in San Bernardino
An ADU kitchen build-out typically runs $14,000 to $24,000 for a compact layout with a range, refrigerator, sink, and code-required ventilation.
How we do it
We design the kitchen within the ADU footprint, run the dedicated circuits, install cabinetry and counters, and finish with appliances, all under the same ADU contract.
What Kitchen Remodeling Costs in San Bernardino
| Item | Typical range in San Bernardino |
|---|---|
| Full kitchen remodel | $32,000 – $58,000 |

How long does a kitchen remodel take in San Bernardino?
A full kitchen remodel in San Bernardino usually takes 5 to 8 weeks from demo to final inspection. Permits and the older-home electrical upgrades that often come with it can add a week or two, and we sequence those early so the ordering lead times run in parallel with construction. Call (855) 949-1913 for a schedule based on your actual scope.
Will my San Bernardino kitchen remodel trigger an electrical panel upgrade?
If your home still has a 60-amp panel, yes. A modern kitchen with a range, dishwasher, microwave, and dedicated appliance circuits needs 200-amp service, and many 1950s San Bernardino homes have never been upgraded. We inspect the panel on the first visit and include the upgrade in the fixed price if it’s needed.
Brands We Service in San Bernardino
We build and install prefab ADUs from Abodu and Cover, and we specify James Hardie fiber cement siding for exteriors that have to stand up to San Bernardino’s heat and wildfire interface exposure. We also build Tuff Shed-style structures converted to habitable units. Parts and panels for these brands are ordered through our standard channels, and we coordinate delivery to your San Bernardino site as part of the project schedule. See the full list at our brands.

FAQs About ADU Company in San Bernardino
Yes. Every ADU and kitchen project we build in San Bernardino is permitted through the city’s building department, and we pull the permits ourselves and schedule the inspections. San Bernardino’s pre-1970 housing stock means many permits also cover electrical panel upgrades and sewer work, which we handle as part of the same permit set. Call (855) 949-1913 for a conversation about what your specific property will need.
We’re state-licensed and insured, and we’ve built ADUs across San Bernardino’s wildfire interface zones where the city requires fire-resistant cladding like James Hardie fiber cement and specific venting details. The requirements depend on your parcel’s exact hazard designation, and we check that early in the estimate so it’s priced correctly from the start. We serve ZIPs 92418, 92423, 92424, and 92427.
That depends on the scope and the permit queue, but we typically schedule site walks within three to five business days and break ground within four to eight weeks after the contract is signed. Prefab ADUs can move faster because the structure is built off-site while we handle site work and the electrical and sewer upgrades in parallel. Call (855) 949-1913 for an exact timeline on your project.
