ADU Company in San Bernardino, CA

Kitchen remodeling in San Bernardino means working with 1940s through 1970s single-story stucco homes, shallow slabs, aging electrical panels, and intense inland heat that punishes cheap materials. We’re Home Base ADU Builders, and we’ve handled San Bernardino residential projects since 2016. Our focus stays on three things: accessory dwelling units, kitchen remodeling, and bathroom remodeling. Call (866) 403-9834 when you’re ready to talk through your kitchen.

Why San Bernardino Homes Are Different

San Bernardino’s housing stock runs heavily toward mid-century single-story stucco-over-wood-frame tract homes and postwar builds, with a pocket of pre-war bungalows closer to downtown. That means kitchen work here rarely starts with a clean slate. We’re typically opening walls to find original 60-amp or 100-amp panels, cloth-wrapped wiring, cast-iron drain lines, and slab floors that were poured without the reinforcement modern tile and stone want to sit on. The city’s hot semi-arid climate adds another layer: summers routinely push past 100F, and Santa Ana winds kick dust and dry heat through older window and vent penetrations. Kitchens here need ventilation that actually moves hot air out, insulation that holds cooling loads down, and finishes that won’t warp when indoor humidity swings between air conditioning and dry wind events. In the numbered-street neighborhoods and the older grid blocks around downtown and the 215, we consistently find unpermitted past work – a patio enclosure turned breakfast nook, a moved gas line nobody pulled a permit for. That history changes scope, and it’s exactly the kind of thing we plan for from the first site walk.

Our Main San Bernardino Services

The two projects San Bernardino homeowners call us about most are ADU construction and bathroom remodeling.

ADU Builders in San Bernardino

San Bernardino’s wide, flat lots in the older grid neighborhoods make detached backyard ADUs and garage conversions far more common here than the side-yard infill you’d see in denser LA County cities. Most of our San Bernardino ADU work involves tying into aging electrical panels and plumbing, evaluating shallow garage slabs off the alley, and planning cooling loads for 100F-plus summers. We match you to the right ADU path – prefab or custom, budget-conscious or premium – rather than pushing one product. ADU Builders in San Bernardino covers the full breakdown.

Bathroom Remodeling in San Bernardino

San Bernardino bathrooms from the 1940s through 1970s were built tight and utilitarian – three-foot showers, single vanities, and original cast-iron stacks that are now at the end of their service life. Our bathroom remodeling in San Bernardino handles the realities of those older homes: slab-level plumbing access, venting corrections, and moisture control for a climate that swings from dry heat to cool mountain-adjacent nights. Bathroom Remodeling in San Bernardino has the full scope and pricing.

Kitchen Remodeling in San Bernardino

Kitchen remodeling in San Bernardino is rarely a cosmetic update. The city’s housing era – mostly 1940s to 1970s single-story stucco – means we’re routinely opening walls to find outdated wiring, undersized plumbing, and slab conditions that need correction before cabinets and tile go in. Add the inland heat, and the work becomes as much about ventilation, insulation, and cooling-load planning as it is about countertops and cabinet faces. Home Base ADU Builders has served San Bernardino since 2016, and this is the kind of work we do every week. If you’re comparing scope and method before committing, start with Kitchen Remodeling for the broader picture, then read on for how we price and plan locally.

Full Kitchen Renovation

Signs you need it

Your kitchen’s layout fights you daily, cabinet boxes are sagging or water-swollen, and the electrical panel can’t support the appliances you actually use.

What it costs in San Bernardino

In San Bernardino, a full kitchen renovation typically runs $28,000 to $65,000 depending on cabinet grade, countertop material, and how much wiring and plumbing correction the house needs.

How we do it

We open the walls, correct wiring and supply lines to current code, re-insulate for the inland heat, then set cabinets, counters, tile, and ventilation as one coordinated crew.

Cabinet and Countertop Replacement

Signs you need it

Boxes are structurally sound but faces are dated, drawer glides are failing, or laminate counters are peeling at the seams from years of dry heat.

What it costs in San Bernardino

Mid-range kitchen cabinet and countertop replacement in San Bernardino spans $8,000 to $22,000, with the final number driven by linear feet and stone or quartz selection.

How we do it

We measure, order, and swap in staged phases so the sink and cooktop are down for days, not weeks, and we re-level everything to San Bernardino’s typical slab deviations.

Kitchen Island Addition

Signs you need it

Your kitchen has the floor space for an island but lacks a prep surface, seating, or a second sink zone, and the existing layout wastes the room’s footprint.

What it costs in San Bernardino

A kitchen island addition in San Bernardino runs $5,200 to $16,000 when it’s built into an existing kitchen, with electrical and plumbing runs accounting for a meaningful share.

How we do it

We locate and route slab penetrations for power and water, frame the island to your work triangle, then finish with the same counters and millwork as the perimeter run.

What Kitchen Remodeling Costs in San Bernardino

Item Typical range in San Bernardino
Full kitchen renovation $28,000 – $65,000
Cabinet and countertop replacement $8,000 – $22,000
Kitchen island addition $5,200 – $16,000

How long does a kitchen remodel take in San Bernardino?

A full San Bernardino kitchen remodel takes 4 to 8 weeks on average. Cabinet-only work runs 1 to 2 weeks. Older homes with electrical panel swaps or slab-level plumbing correction push toward the longer end. Call (866) 403-9834 for a schedule specific to your house.

Will my San Bernardino kitchen remodel pass inspection?

We pull permits, schedule inspections, and correct unpermitted past work as part of the scope. San Bernardino inspectors focus heavily on electrical upgrades, gas line placement, and ventilation. Call (866) 403-9834 to walk through your kitchen’s specific history.

What San Bernardino Customers Say

★★★★★ 4.8 from 4+ reviews

"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."

— Robert Hayes

"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."

— Colleen Pruitt

"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."

— Priya Mehta
