ADU Company in Pomona, CA

Kitchen remodeling in Pomona usually means working inside a 1920s to 1970s stucco home with older wiring, a panel that’s already maxed out, and a floor plan built for a different era of living. The Pomona Valley’s hot inland summers and occasional winter frosts also shape the work: appliances need real ventilation, and materials need to handle temperature swings without failing. Foundry ADU Builders handles kitchen remodels in Pomona as part of ADU construction or as standalone projects, and we’ve done enough of them to know where these older Pomona homes fight back.

Why Pomona Homes Are Different

Pomona’s housing stock is a mix of 1920s through 1970s single-story stucco tracts and Spanish-revival homes, most on generous R-1 lots with detached or alley-facing garages. That sounds like a simple canvas until you open the walls. Many of these homes still carry knob-and-tube or early cloth-wrapped wiring. Electrical panels are frequently 60 or 100 amps, nowhere near what a modern kitchen with an induction range, microwave, and dishwasher pulls. Sewer laterals are often aging clay or cast iron, and adding a second kitchen or re-plumbing a primary one can mean scoping the line to the street.

The climate adds another layer. Pomona gets stretches well over 100°F in summer, but nights can drop cold and winter frosts are real. A kitchen that works fine in coastal Orange County will overcook a Pomona home if the range hood isn’t vented properly and the attic insulation isn’t addressed while the ceiling is open. We plan for that from the first site visit.

Our Main Pomona Services

Most Pomona homeowners come to us for one of two things: building an ADU on the back half of the lot, or remodeling a bathroom inside the main house, often as part of an ADU project. Here’s what each involves locally.

ADU Builders in Pomona

Pomona’s deep lots and alley access make rear-detached ADUs and garage conversions the dominant play here. The city’s pre-approved ADU plans, combined with state law that limits local discretion on size and parking, mean Pomona homeowners can often go bigger and faster than in neighboring Claremont or San Dimas, where extra local review layers on time. We build across the full spectrum: site-built, factory-assembled modular from Mighty Buildings or Boxabl, and design-forward prefab from companies like Abodu and Plant Prefab. The right method depends on your lot, your budget, and how fast you want the unit occupied. Find the full breakdown on our ADU Builders in Pomona page.

Bathroom Remodeling in Pomona

Bathrooms in Pomona’s older homes are typically small, with cast-iron drain lines and galvanized supply pipes that have been slowly constricting for decades. Adding an ADU usually means adding a bathroom, and that’s where our in-house team carries the project from rough plumbing to tile and fixtures without handing off to a second contractor. We also remodel existing bathrooms in the main house, often for Pomona homeowners preparing for multigenerational living. Ventilation matters here more than people expect: a bathroom fan that just recirculates won’t handle Pomona’s heat, and we spec real exhaust. See Bathroom Remodeling in Pomona for specifics.

Kitchen Remodeling in Pomona

Most Pomona kitchens we open up were built before dishwashers, microwaves, and induction cooktops existed, and the electrical infrastructure tells that story immediately. Homes in the 91766 and 91768 ZIP codes especially run into undersized panels and cloth-wrapped wiring that has to come out before anything new goes in. The heat is the other constant: a Pomona kitchen needs a range hood that actually vents outside, not a recirculating unit, and insulation upgrades while the walls are open save real money on cooling bills. We build kitchens as part of ADU interiors or as standalone remodels, and the scope usually includes the structural fixes that make the finish work last. This is the same work described on our Kitchen Remodeling service page, applied to Pomona’s older housing stock.

Full Kitchen Remodel

Signs you need it

The layout fights you daily: no landing space next to the range, one narrow path through the kitchen, and storage that doesn’t fit modern appliances.

A full kitchen remodel in Pomona typically runs $45,000 to $85,000 depending on cabinet quality, appliance tier, and how much electrical and plumbing has to be replaced.

How we do it

We demo to the studs, upgrade the panel and wiring if needed, re-plumb supply and drain lines, then rebuild with new cabinets, countertops, appliances, and ventilation.

Kitchen Update – Cabinet Refacing and Countertops

Signs you need it

The cabinets are structurally sound but the doors are dated, or the countertop is worn and stained while the bones of the kitchen work fine.

What it costs in Pomona

Cabinet refacing with new countertops in Pomona typically runs $18,000 to $35,000, less than half the cost of a full tear-out.

How we do it

We replace doors and drawer fronts, re-laminate or re-veneer the boxes, swap countertops, and update hardware and sinks in place.

Brands We Service in Pomona

What Pomona Customers Say

★★★★★ 4.8 from 4+ reviews

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

— Marisol Delgado

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

— Brandon Wong

"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."

— Holly Reed
