ADU Company in Pomona, CA

Kitchen remodeling in Pomona means working with homes built between 1900 and 1970, and that changes everything about the job. Craftsman bungalows near downtown have small, compartmentalized kitchens with walls that may or may not be structural. The 1950s and 60s stucco tracts east of the 57 have galley layouts and original wiring that rarely meets today’s code for appliance circuits. Add Pomona’s hot inland summers, and ventilation, insulation, and appliance heat output become real design factors, not afterthoughts. Colonial ADU Builders handles the full kitchen remodel, from permit drawings to the final appliance install, with our own crews. Call (877) 265-9846 for a free estimate.

Why Pomona Homes Are Different

Pomona’s housing stock is older and deeper than most of the San Gabriel Valley. The pre-war Craftsman and California bungalow stock around Lincoln Park and the downtown core sits on deep, narrow lots with detached garages off the alley. Those kitchens were built for iceboxes and gas ranges with a single light fixture overhead. When we open the walls, we typically find knob-and-tube remnants, galvanized supply lines, and floor framing that has settled unevenly over 90 years. The 1950s through 1970s stucco tracts in the 91766 and 91768 ZIP codes are different: post-and-beam or slab foundations, original copper that is often at the end of its life, and kitchens sized for a table that no longer fits how people cook.

Climate drives decisions here more than most homeowners expect. Pomona regularly sees summer days over 100°F, and the Santa Ana winds in the fall are dry and relentless. A kitchen without a properly sized range hood or ventilation system traps heat and cooking exhaust. We plan for higher-capacity venting, heat-resistant countertop materials, and window treatments that block western exposure. Homes in the foothill edges, especially north of the 10 toward the 91797 ZIP, also need siding, window, and vent selections that hold up to ember exposure during high-wind fire weather. These are exactly the conditions that separate a Pomona kitchen remodel from a generic one.

The permit process in Pomona is workable, but it rewards preparation. The city enforces California’s energy code strictly, so older homes often need a panel or service upgrade before a kitchen can legally pass inspection. If a house still has a 60-amp or 100-amp panel, adding an electric range, microwave, or dedicated appliance circuits will trigger the upgrade. We pull permits on every kitchen remodel we do in Pomona, and we coordinate the electrical, plumbing, and structural inspections so homeowners do not have to decode the city’s plan check comments themselves.

Our Main Pomona Services

Pomona homeowners call us most often for two things: building an ADU on a deep lot or converting an alley-facing garage, and remodeling a bathroom in an older home that has outlived its original plumbing. Both jobs share the same Pomona realities: older foundations, tight setbacks, and the need to coordinate permits carefully.

ADU Builders in Pomona

Pomona’s ADU work is dominated by the rear-alley garage. Most of the older single-family blocks, especially in 91766 and the streets north of Holt, have detached garages that open onto the alley. Those structures already have a roof, a footprint, and often a subpanel, which makes conversion faster and less disruptive than a ground-up build. The trade-off is that many of these garages were built as unpermitted or lightly permitted structures, so we spend time evaluating the slab, framing, and electrical before committing to a plan. Colonial ADU Builders is brand-agnostic: we compare prefab options from seven manufacturers against a site-built approach and recommend what actually fits the lot.

Bathroom Remodeling in Pomona

Bathrooms in Pomona’s older homes are usually small, often 5 by 7 feet or less, with cast-iron drain lines that have been corroding for half a century. Remodeling them properly means opening the floor, replacing the waste and vent piping, and re-waterproofing the shower pan to modern standards. In homes from the 1950s and 60s, we also find original tile set in mud beds that weigh far more than the framing was designed to carry. We handle the entire remodel in-house: demo, rough plumbing, tile, fixtures, and finish. The result is a bathroom that works, vents properly in Pomona’s heat, and will not leak into the crawlspace.

Kitchen Remodeling in Pomona

Kitchen Remodeling in Pomona

Kitchen remodeling in Pomona is not a cosmetic refresh. On the bungalow-era homes, it usually means removing a load-bearing wall or two to open the kitchen into the dining room, upgrading the electrical service, and re-plumbing the supply and drain lines for a modern appliance layout. On the mid-century tract homes, it typically means gutting a narrow galley, relocating the refrigerator wall, and building cabinetry that uses every inch of a 9-by-12-foot footprint. In both cases, Pomona’s summer heat and older duct systems make ventilation and appliance selection a bigger part of the conversation than most remodelers are willing to have.

Because we are Kitchen Remodeling specialists with in-house crews, the same team that tears out the old kitchen also hangs the drywall, sets the cabinets, tiles the backsplash, and installs the range hood. There is no hand-off to a third-party finish crew. If the home also needs an ADU or a bathroom remodel, those trades are already on the same schedule.

Galley Kitchen Reconfiguration

Signs you need it

Your 1950s or 1960s Pomona kitchen is a single narrow corridor with counters on both sides, one person can barely work in it, and the original oven and cooktop locations block the only natural light.

What it costs in Pomona

A galley kitchen reconfiguration in Pomona typically lands between $45,000 and $75,000, with the higher end applying to homes that need structural work to move or remove a wall.

How we do it

We verify which walls are load-bearing, pull permits, relocate plumbing and electrical to the new layout, then build out the new kitchen with our own finish crews, including custom or semi-custom cabinetry, countertops, and a properly sized vent hood.

Full-Gut Kitchen Remodel

Signs you need it

The kitchen in your pre-war Pomona bungalow still has the original layout with a single sink, no dishwasher, and a floor that slopes toward the crawlspace, and you want a completely new room rather than a patch job.

What it costs in Pomona

A full-gut kitchen remodel in Pomona starts around $65,000 and can reach $110,000 or more depending on the structural repairs, service upgrade, and finish level.

How we do it

We strip the room to the studs, repair or reinforce the framing, upgrade the electrical panel and wiring, replace the plumbing rough-in, then rebuild the kitchen with modern insulation, ventilation, and a layout that works for how your household cooks.

What Kitchen Remodeling Costs in Pomona

Item Typical range in Pomona
Galley kitchen reconfiguration $45,000 – $75,000
Full-gut kitchen remodel $65,000 – $110,000+
Kitchen cabinet replacement only $18,000 – $35,000

How long does a kitchen remodel take in Pomona?

A typical Pomona kitchen remodel runs 8 to 12 weeks from demo to final inspection, though structural work, panel upgrades, or unexpected framing repairs on older homes can add 2 to 3 weeks. We give you a written schedule before demo starts and update it as inspections clear.

Will a Pomona kitchen remodel require an electrical panel upgrade?

It usually does on homes built before 1980. If you are adding an electric range, microwave, or dedicated appliance circuits and your panel is 100 amps or less, Pomona’s plan check will require a service upgrade. We include that in the estimate up front, not as a change order later.

Brands We Service in Pomona

Colonial ADU Builders works with multiple manufacturers rather than pushing one. On Pomona ADU and exterior projects, we regularly specify our brands: Boxabl for compact, fast-set units, Plant Prefab for architect-led panelized designs, and James Hardie for fiber-cement cladding that holds up to Pomona’s heat and fire weather. Parts and finish materials are ordered per project, with local supply runs coordinated around the build schedule.

Pricing for ADU Company in Pomona, CA

Service Typical range in Pomona
Galley kitchen reconfiguration $45,000 – $75,000
Full-gut kitchen remodel $65,000 – $110,000+
Kitchen cabinet replacement only $18,000 – $35,000
ADU garage conversion $85,000 – $150,000

Bathroom update (cosmetic) $12,000 – $25,000

Pomona pricing is pushed upward by two things: the age of the housing stock and the city’s code enforcement. Older homes routinely need panel upgrades, foundation repairs, or full drain-line replacement before finish work can start, and those costs hit early in the job. Newer homes in the 91768 ZIP tend to price lower because the underlying systems are still sound. Every estimate we give is a fixed, written, line-item price. We do not issue change orders unless you approve a change.

★★★★★ 4.8 from 4+ reviews

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

— Todd Rhodes

"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."

— Elena Torres

"Every invoice was tied to a completed milestone, so I always knew what I was paying for."

— Beatriz Mendoza
