ADU Company in San Bernardino, CA

Kitchen remodeling in San Bernardino usually means working inside a mid-century ranch or a pre-war bungalow, not a new build. Most of the city’s housing stock dates from the 1940s through the 1970s, so we’re regularly opening walls to find outdated wiring, cast-iron drain lines, and layouts that never anticipated a dishwasher, let alone an island. The heat matters too: a San Bernardino kitchen needs cooling loads and ventilation that coastal homes don’t. That’s where we come in. Sunburst ADU Builders handles the full-scope kitchen remodel – from panel upgrades to the finished backsplash – and we’ve served San Bernardino since 2018.

Why San Bernardino Homes Are Different

San Bernardino has some of the largest single-family lots and lowest per-square-foot home values in the Inland Empire. That math changes how we approach kitchen remodels. A homeowner here can justify a full gut renovation on a house worth $450,000 when the same project in a coastal market would feel oversized. The lots also mean many homes are wide and shallow, with kitchens that sit in the middle of the floor plan and rely on a single window for light. Opening a wall to the dining room is common work here.

The 1940s-through-1970s tract housing is the backbone of the city. Those kitchens were built small and closed off, with original electrical panels that cannot carry a modern appliance load. We regularly see 60-amp panels in homes across the 92418 and 92427 ZIP codes. Before any remodel starts, the panel usually needs a service upgrade. Older neighborhoods near the downtown core have pre-war bungalows with legacy sewer runs and floor joists that have settled. The north end has newer subdivisions, but even those often have builder-grade kitchens that are now 20-plus years old. Santa Ana winds and 100°F summer days mean range hoods should vent outside, and any window replacement has to hold up to real heat. We plan for that from the first measurement.

Our Main San Bernardino Services

Most San Bernardino homeowners call us about two things: adding an ADU to their oversized lot, or fixing a bathroom that has not been touched since the Eisenhower administration. Both jobs share the same local constraints – older main homes, panel capacity, and the need for a contractor who knows the city’s plan-check process.

ADU Builders in San Bernardino

San Bernardino’s wide, shallow 1950s and 1960s lots are practically built for detached ADUs, but setback and lot-coverage math with the existing garage can get tight. We handle that from day one. Since we are manufacturer-agnostic, we can compare a Mighty Buildings 3D-printed panel approach against a conventional stick-built unit for your specific lot, budget, and timeline. Many San Bernardino jobs also start with legalizing an old unpermitted garage conversion before adding a new unit. We walk you through the entire process. ADU Builders in San Bernardino offers the full scope – foundation to finished kitchen, one team.

Bathroom Remodeling in San Bernardino

Bathrooms in San Bernardino’s mid-century homes are small, often with original cast-iron tubs, failing tile grout, and no exhaust fan. The hot, dry climate actually makes proper ventilation more important here, not less – trapped shower steam in a 110°F attic can warp framing within a few summers. We tear out to the studs, fix what the 1970s left behind, and rebuild with proper waterproofing and ventilation. Bathroom Remodeling in San Bernardino covers full-scope bathroom work for the same team that builds your kitchen or ADU.

Kitchen Remodeling in San Bernardino

Kitchen Remodeling in San Bernardino

Kitchen remodeling in San Bernardino typically runs $32,000 to $58,000 for a mid-range full remodel, with smaller updates starting around $12,000. The biggest cost variable here is what we find when we open the walls: older homes in the 92424 and 92427 ZIP codes frequently need panel upgrades and re-wiring before any new appliances go in. We do complete kitchen remodels – Kitchen Remodeling is a core service, not an add-on – and most jobs are in homes built between 1940 and 1975, so we plan for the unknown from day one.

Cabinet Replacement and Layout Rework

Signs you need it

Cabinet doors are delaminating at the edges, drawer slides stick, or the kitchen’s work triangle puts the sink, stove, and refrigerator in three different zip codes.

What it costs in San Bernardino

Refacing runs $6,500 to $15,000; full replacement with layout changes typically lands between $15,000 and $28,000 depending on linear feet and whether we’re moving plumbing or gas lines.

How we do it

We measure, remove existing boxes carefully enough to check for water damage behind them, and install new cabinets with soft-close hardware and leveled bases – no shim stacks that fail in five years.

Countertops and Island Addition

Signs you need it

Original 1960s laminate is burned near the stove, water has swollen the substrate at the sink, or the kitchen has the floor space for an island but no existing surface worth building around.

What it costs in San Bernardino

Quartz or granite countertops run $3,400 to $9,000 installed, and adding a modest island with a stone top typically falls between $4,000 and $11,000 including base cabinets.

How we do it

We template after the cabinet work is locked in, fabricate the stone off-site to keep dust out of your house, and install with a focus on seams that stay flat through San Bernardino’s summer heat cycles.

What Kitchen Remodeling Costs in San Bernardino

Item Typical range in San Bernardino
Full kitchen remodel (mid-range) $32,000 – $58,000
Cabinet replacement + layout rework $15,000 – $28,000
Countertops (quartz/granite, installed) $3,400 – $9,000

What pushes price up in San Bernardino specifically: panel upgrades, re-wiring, moving gas lines, and fixing water damage that mid-century homes often hide behind original cabinets. We quote with a written line-item scope and fixed pricing, so you are not surprised when the wall opens up.

How long does a kitchen remodel take in San Bernardino?

Plan on 5 to 9 weeks for a full remodel, depending on whether we are moving plumbing or upgrading the electrical panel. Permits with the city add one to two weeks before demo starts.

Will the price change once work starts?

Our fixed pricing means the quote holds unless you change the scope or we uncover a structural issue hidden behind the walls. We show you photos of anything unexpected before we proceed. Call (855) 676-6807 for a free estimate.
