ADU Company in San Bernardino, CA

Kitchen remodeling in San Bernardino comes with a specific set of realities: homes built mostly between the 1940s and 1970s, scorching Inland Empire summers, and layouts that weren’t designed for how families cook and gather today. Westminster ADU Builders approaches every San Bernardino kitchen project with those conditions in mind, from the first measurement to the final cabinet pull. We’re an ADU specialist first, but the kitchens we remodel inside those ADUs and in existing San Bernardino homes get the same level of planning and craftsmanship. Call (833) 620-3521 to talk through what’s possible on your lot.

Why San Bernardino Homes Are Different

San Bernardino’s housing stock was largely built during one long surge between the 1940s and the 1970s, and that shapes nearly every kitchen we open. Homes in ZIPs like 92404, 92405, and 92411 typically have kitchens that were compartmentalized on purpose: a long narrow galley or a closed-off room with one small window. The plumbing and gas lines are old enough that any real remodel means updating them, not just covering them up. Wiring is often aluminum or undersized by modern code, and the electrical panel usually predates today’s appliance loads, so a kitchen that’s getting a new range, hood, and refrigerator frequently needs a subpanel upgrade we plan for on day one.

The climate pushes things in another direction. San Bernardino summers routinely pass 100°F, and any kitchen that lacks proper ventilation becomes a heat trap from June through September. We spec range hoods that actually move air, not the builder-grade recirculating units that came with the house. Santa Ana winds in fall mean dust gets everywhere during construction, so we seal the work zone even on smaller remodels. Homes in the foothill-adjacent stretches of 92404 and 92407 sit close enough to wildland areas that fire-resistant materials become part of the conversation when we’re choosing exteriors, windows, and venting details that connect the kitchen to the outside.

What makes San Bernardino genuinely different from its Inland Empire neighbors is how many mid-century homes sit on large lots with the original floor plan intact. That’s good news for anyone considering a kitchen expansion into what used to be a porch or a garage-adjacent utility room. It’s also a reminder that slab foundations and older framing don’t always line up square anymore, which is exactly the kind of thing we account for before cabinets are ordered.

Our Main San Bernardino Services

San Bernardino homeowners call us for two projects more than anything else: building accessory dwelling units and remodeling bathrooms. Both are jobs where the city’s older housing stock and hot, dry climate change the right approach.

ADU Builders in San Bernardino

San Bernardino is one of the few Inland Empire cities that has openly embraced state ADU law, which means converting a detached garage or adding a backyard casita is actually realistic here without fighting the planning department for a year. The challenge is that many of those older garages in ZIPs like 92404 and 92405 were built on shallow footings with no insulation, so a “simple” garage conversion often requires a foundation upgrade and new electrical service before framing even starts. We’ve worked through enough of those to know where the surprises hide and how to price for them honestly. ADU Builders in San Bernardino covers the full breakdown of prefab versus site-built paths, permitting, and realistic timelines.

Bathroom Remodeling in San Bernardino

Bathrooms in San Bernardino’s 1950s and 1960s homes are usually small, with cast-iron plumbing that’s near the end of its service life and tile set over drywall that was never meant to get wet. A remodel here is less about cosmetic updates and more about correcting water damage that’s already started where you can’t see it. The dry climate doesn’t help: it can hide slow leaks for years until the subfloor tells you something’s wrong. We handle bathroom remodels inside new ADUs and existing homes with the same team, which means no handoffs between contractors. Bathroom Remodeling in San Bernardino explains the typical scope, costs, and what to expect in older houses.

Kitchen Remodeling in San Bernardino

A kitchen remodel in San Bernardino usually means opening a closed-off 1950s or 1960s kitchen, replacing plumbing and wiring that have been in place for sixty years, and designing around the reality of three-digit summer temperatures. We plan for the things you can’t see: old slab penetrations, undersized panels, and ventilation that actually keeps the room habitable in August. As our Kitchen Remodeling overview explains, every project starts with the lot, the budget, and how the family uses the space, not with a catalog of cabinets.

Full Kitchen Renovation

Signs you need it

Your kitchen’s doors stick, the layout forces two people into a single narrow aisle, and every summer dinner becomes a race against the heat when the oven goes on.

What it costs in San Bernardino

Full kitchen renovations in San Bernardino typically run from $28,000 to $90,000, with the older homes in 92404 and 92405 often landing on the higher side once electrical and plumbing are brought current.

How we do it

We start with a structural and systems check, build out the new layout with all rough plumbing and electrical to current code, then install the new finishes, ventilation, and fixtures before a final walk-through and cleanup.

Kitchen Cabinet and Countertop Refresh

Signs you need it

Your cabinet boxes are still solid, but the doors are warped, the drawer slides have gone soft, and the countertop shows years of knife marks and heat rings.

What it costs in San Bernardino

A cabinet refinish or reface with new countertops in San Bernardino typically falls between $9,500 and $25,000, depending on whether you’re refacing, replacing doors, or going with full new boxes.

How we do it

We measure and order doors or full cabinet sets, pull everything down to the studs if needed, then reinstall with new hardware, fresh counters, and tightened, aligned drawer faces.

Small Kitchen and Galley Upgrade

Signs you need it

You have a narrow galley kitchen that belongs in another decade, and your goal is to make it brighter and more functional without adding square footage you don’t have.

What it costs in San Bernardino

Galley and small kitchen remodels in San Bernardino typically start around $12,000 and run up to $30,000 when they include new cabinetry, backsplash, countertops, and a vented hood.

How we do it

We work the existing footprint hard: full-height cabinets where they’ll fit, a properly vented hood, layered lighting that makes the room feel wider, and materials that hold up to daily use in a hot kitchen.

What Kitchen Remodeling Costs in San Bernardino

Item Typical range in San Bernardino
Full kitchen renovation $28,000 – $90,000
Cabinet reface with new countertops $9,500 – $25,000
Small galley kitchen remodel $12,000 – $30,000

What pushes a San Bernardino kitchen toward the top of those ranges is almost always the state of the hidden systems: older homes in 92411 and 92405 regularly need new subpanels, upgraded gas lines, and rerouted drain lines, and those run well ahead of any finish choice. We quote line-item prices before work begins and we don’t issue change orders when we discover a plumbing or wiring issue that should have been obvious to any experienced remodeler walking the site.

How long does a full kitchen remodel take in San Bernardino?

A full kitchen remodel in San Bernardino typically takes six to ten weeks, depending on what we find behind the walls and under the floor. Older homes with slab plumbing and outdated electrical panels take longer than a straightforward cabinet replacement in a newer 92407 home. Call (833) 620-3521 for a timeline based on your specific kitchen.

Will my kitchen remodel require a permit in San Bernardino?

Yes, any kitchen remodel that moves plumbing, electrical, or walls requires a permit from the City of San Bernardino. A like-for-like cabinet and countertop swap may not, but we handle the permitting process on every job that needs it. Call (833) 620-3521 for a straight answer on your project.

Brands We Service in San Bernardino

Our ADU work brings us into regular contact with panelized and prefab systems from our brands, including Cover, Dvele, and Mighty Buildings. For San Bernardino projects, we stock common fasteners, flashing, and installation hardware locally so factory-built components don’t sit waiting on a parts order. Material turnarounds stay short, which matters when the Santa Anas are forecast and a panel delivery can’t be delayed.

Pricing for ADU Company in San Bernardino, CA

Service Typical range in San Bernardino
Full kitchen renovation $28,000 – $90,000
Cabinet reface with new countertops $9,500 – $25,000
Small galley kitchen remodel $12,000 – $30,000

Kitchen remodeling prices in San Bernardino get pushed upward by two local factors more than anything else: the age of the electrical and plumbing systems in mid-century homes, and the need for serious ventilation in a city where summer highs routinely exceed 100°F. Westminster ADU Builders has served San Bernardino since 2016, and every quote we give is a fixed, line-item price before work starts, no change orders later.

Neighborhoods We Serve in San Bernardino

We work throughout San Bernardino, from the older mid-century neighborhoods around 92404 and 92405 to the newer developments on the north and east edges in 92407. Our team is familiar with the specific quirks of each area: the detached garages and shallow footings in the older central neighborhoods, the attached garages and modern framing in 92407, and the wildland-adjacent lots where fire-resistant exterior choices matter most.

  • North Park / Arrowhead area (92404)
  • Downtown and central San Bernardino (92411)
  • Del Rosa (92404)
  • Verde Farms and the north edge (92407)

Typical response time for a walk-through and estimate across these neighborhoods is a few business days from the first call.

Service Area – Cities Near San Bernardino

Westminster ADU Builders also serves the communities just beyond San Bernardino’s city limits, where the housing stock and permitting situations shift from neighborhood to neighborhood. We work regularly in Muscoy, CA, where large lots and a semi-rural feel create different ADU opportunities, and in Highland, CA, where the hillside lots change foundation approaches. Loma Linda, CA projects often involve tighter lot sizes, and Rialto, CA mixes mid-century housing with newer subdivisions. The same team covers all of these areas.
