ADU Company in Colton, CA

Kitchen remodeling in Colton usually means working inside a mid-century stucco home where the original footprint was built around a compact galley or closed-off kitchen, not the open-plan layouts common in newer Inland Empire subdivisions. We handle the whole job, from reconfiguring walls to replacing cabinets and counters, and we coordinate the permit work Colton’s building department requires. Newport Beach ADU Builders has served Colton since 2016. Call (844) 934-0236 for a free estimate on your kitchen remodel.

Why Colton Homes Are Different

Colton is a small, older Inland Empire railroad town hemmed in by freeways and rail yards, so most remodeling work here happens in established 92324 neighborhoods where homes were built in the 1950s and 1960s. The housing stock is dominated by single-story stucco tract and ranch homes, many with detached garages at the rear of the lot. When we open up a Colton kitchen, we’re usually dealing with original framing, older electrical panels, and floor plans that walled the kitchen off from the living area.

The hot, dry summers matter too. A Colton kitchen that gets afternoon sun through an unshaded west-facing wall will bake, so we pay attention to insulation, window placement, and ventilation when we remodel. Winter rains bring a different problem: older stucco homes here often have flat or low-slope roof sections that drain poorly, and a leak above the kitchen ceiling is a common reason homeowners call us in the first place. We check the roof and drainage around the kitchen area before we start, because a new kitchen under a leaking roof is a waste of money.

Most Colton lots are tighter than what you find in newer subdivisions nearby. That affects how we stage materials, where we put the dumpster, and how we sequence a remodel when there’s no side yard to spare. It’s the kind of constraint that only shows up when you build here regularly, and it’s why a contractor who knows Colton’s older streets will plan differently than one who works mostly in new construction.

Our Main Colton Services

Colton homeowners reach out to us most often for two things: adding an ADU to an existing lot and updating bathrooms in older homes. Both involve Colton’s permit process and both benefit from a contractor who knows mid-century construction.

ADU Builders in Colton

Adding an ADU in Colton usually starts with a detached rear garage or an underused section of the backyard. The rear detached garage off the alley is the classic Colton starting point, because narrow alleys and shallow lots mean the setback and lot-coverage math, not design preference, usually decides whether the unit fits. We walk the site, check the existing structure, and give you a straight answer on what Colton’s zoning will allow. ADU Builders in Colton.

Bathroom Remodeling in Colton

Older Colton bathrooms tend to be small, with original cast-iron plumbing and tile set over mud beds. We remove them down to the studs when needed, replace the rough plumbing, and rebuild with waterproofing that holds up to hard Inland Empire water. Because many Colton homes sit on raised foundations, we can often reroute drain lines without major concrete work. Bathroom Remodeling in Colton.

Kitchen Remodeling in Colton

Kitchen remodeling in Colton often means taking a closed-off galley kitchen in a 1950s or 1960s stucco ranch and opening it to the living area, replacing everything from the original wiring to the cabinet layout. The older homes here were not built for modern appliances, large fridges, or the kind of venting a gas range needs, so the job usually includes panel upgrades, new circuits, and rerouted plumbing. This is where our kitchen and bath remodeling division keeps the project under one contractor relationship, from Kitchen Remodeling plans to finished counters.

Galley to Open-Plan

Signs you need it

The kitchen is walled off from the living area, the refrigerator blocks a walkway, and the only natural light comes from a single small window over the sink.

What it costs in Colton

Opening a load-bearing wall and reconfiguring a Colton galley kitchen typically runs $45,000 to $75,000 depending on structural work and finish level.

How we do it

We assess which walls are load-bearing, spec the beam, pull the Colton permit, reframe, reroute mechanicals, and finish the new open space to match the rest of the home.

Full Gut and Rebuild

Signs you need it

The cabinets are original, the electrical is ungrounded, the floor is sagging, and the layout no longer works for how your family cooks.

What it costs in Colton

A full gut kitchen rebuild in Colton, including new subfloor, wiring, plumbing, cabinets, counters, and appliances, runs $55,000 to $90,000.

How we do it

We demo to the studs, update the subfloor and rough framing, run new electrical and plumbing, install new drywall, cabinets, counters, and trim, then handle the final inspection and cleanup.

What Kitchen Remodeling Costs in Colton

Item Typical range in Colton
Galley to open-plan (structural) $45,000 – $75,000
Full gut and rebuild $55,000 – $90,000
Cabinet and counter replacement only $18,000 – $35,000

Prices in Colton run higher when a wall removal exposes hidden issues like undersized floor joists, termite damage, or a kitchen wall that was never properly flashed against the roof. That is exactly why we write fixed-price, line-item quotes after we see the framing, not before. Call (844) 934-0236 for an exact number on your kitchen.

How long does a kitchen remodel take in Colton?

Most Colton kitchen remodels take 6 to 10 weeks from demolition to final inspection, depending on structural work and what the city inspection schedule looks like. Cabinets with long lead times can extend that. Call (844) 934-0236 for a schedule based on your specific layout.

Do you pull the Colton permit for a kitchen remodel?

Yes, we pull every Colton permit ourselves and schedule the inspections. Any remodel that moves walls, changes the electrical panel, or reroutes plumbing requires city review, and we handle that paperwork as part of the job.

What Colton 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."

— Heather Ackerman

"Garage conversion to a one bedroom unit. He handled the plans, the city submittal, and every round of corrections. Took six months from first meeting to final inspection and he never once made the permit process my problem."

— Diego Castillo

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

— Malik Nash
