ADU Company in San Bernardino, CA

Kitchen remodeling in San Bernardino works differently than in coastal markets. The city’s 1950s-70s tract homes carry original layouts, aging plumbing, and electrical panels that often need upgrading before a single cabinet goes in. Harvest ADU Builders handles the full kitchen scope, from slab-on-grade plumbing moves to finish carpentry, so you’re not coordinating three separate crews. We build ADUs here too, including kitchen and bathroom finishing inside the new unit. Call (866) 538-0916 when you’re ready to plan.

Why San Bernardino Homes Are Different

San Bernardino sits at the base of the San Bernardino Mountains, which means hot, dry summers with regular triple-digit days and Santa Ana wind events. Any ADU or kitchen build here needs real cooling, not a token wall unit, and insulation that holds up under sustained heat. Homes in the older grid neighborhoods around 92405 and 92410 are mostly single-story stucco over wood frame, with composition shingle roofs and detached two-car garages. Many still run on original 100-amp panels, which changes the budget conversation fast.

The deep lots are a genuine advantage. Rear-alley access in parts of 92405 and 92410 makes detached ADUs and garage conversions feasible without tearing up the front yard. But slab-on-grade construction is common, which affects how you run new drain lines for a kitchen or bathroom. We see this constantly: the structure is the easy part. The utility service upgrade, the panel swap, and the trenching for new plumbing are what actually define the cost and timeline in San Bernardino.

Our Main San Bernardino Services

San Bernardino homeowners call us most about two things: building an ADU on an oversized lot, and remodeling an aging bathroom inside the main house. Both share the same local reality: older panels, slab foundations, and a need for work that passes San Bernardino’s permit review without surprises.

ADU Builders in San Bernardino

San Bernardino’s deep lots and rear garages make ADUs one of the smartest equity plays in the Inland Empire. We handle detached units, garage conversions, and prefab installations matched to your lot and budget rather than a brand we happen to stock. The SB 9 lot-split angle is real here, and so is the utility upgrade conversation that comes with older 100-amp panels. Read the full breakdown at ADU Builders in San Bernardino.

Bathroom Remodeling in San Bernardino

Bathrooms in San Bernardino’s mid-century homes are small, originally built for a different era, and often sit on slab foundations that make moving a drain more involved than it looks. We replace old cast-iron lines, rework layouts, and finish to modern standards without pretending a 1960s bathroom can be flipped in a weekend. The full scope is on this page: Bathroom Remodeling in San Bernardino.

Kitchen Remodeling in San Bernardino

Kitchen remodeling in San Bernardino usually means opening up a closed-off galley in a 1950s-70s tract home, replacing original plumbing that’s outlived its useful life, and adding cooling capacity that actually handles August heat. Slab foundations and aging electrical panels are the two things that shape scope more than cabinet choice in this city. Our in-house team handles the full Kitchen Remodeling scope, from demolition to finished backsplash, so you’re not herding separate trades.

Full Kitchen Renovation

Signs you need it

Your kitchen still has its original 1960s layout, the cabinets are delaminating, and the electrical can’t support modern appliances without tripping breakers.

What it costs in San Bernardino

A full kitchen renovation in San Bernardino typically runs $35,000-$75,000, with slab plumbing moves and panel upgrades pushing toward the higher end.

How we do it

We complete demolition, rework the plumbing and electrical, install new cabinets and counters, and finish with flooring, paint, and trim in one coordinated sequence.

Kitchen Update with Cabinet Refacing

Signs you need it

Your cabinet boxes are structurally sound but the doors are worn, and you want a fresh look without gutting the room.

What it costs in San Bernardino

Cabinet refacing and a light kitchen update in San Bernardino generally costs $15,000-$30,000 depending on door style and hardware.

How we do it

We reface existing cabinet boxes with new doors and veneers, replace hardware, and update counters or backsplash where the budget allows.

What Kitchen Remodeling Costs in San Bernardino

Item Typical range in San Bernardino
Cosmetic update (paint, hardware, backsplash) $8,000-$15,000
Cabinet refacing and light update $15,000-$30,000
Full renovation with layout changes $35,000-$75,000

How long does a kitchen remodel take in San Bernardino?

A full kitchen remodel in San Bernardino usually takes 6-10 weeks. If we’re cutting into slab for plumbing moves or upgrading a panel, expect the longer end. We sequence the work so your kitchen is never torn apart longer than it has to be.

Will my San Bernardino kitchen need a panel upgrade?

Many San Bernardino homes built in the 1950s-70s still run on 100-amp panels that can’t feed a modern kitchen. If your remodel adds a microwave, induction cooktop, or second oven, the panel usually needs to go to 200 amps first.

Brands We Service in San Bernardino

We work with Boxabl, Plant Prefab, and Tuff Shed conversions, and we finish exteriors with James Hardie materials that hold up to San Bernardino heat and foothill wind. Parts and panels are ordered to the job site, not drop-shipped from a warehouse across the country. See our brands for the full rundown.

What San Bernardino Customers Say

★★★★★ 4.8 from 4+ reviews

"The kitchenette layout he suggested made better use of the space than the one on our original sketch."

— Marco Reyes

"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."

— Kristen Fletcher

"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."

— Vikram Sharma
