ADU Company in Montclair, CA
Kitchen remodeling in Montclair usually means reworking a compact 1950s-to-1970s kitchen inside a single-story tract home, often while the rest of the house keeps running. We’re Colonial ADU Builders, and we handle that work with our own crews, from moving gas and drain lines to installing cabinets and countertops. If your Montclair kitchen feels closed off from the living space or still runs on its original wiring, call us at (877) 265-9846. We’ll walk you through what’s realistic for your lot and your budget. This page covers what Montclair kitchens cost to remodel, the sub-jobs inside a typical project, and how we keep the work moving.
Why Montclair Homes Are Different
Montclair is a small, fully built-out city in the Pomona Valley, and most of its housing stock dates from the 1950s through the 1970s. That means single-story tract houses on modest lots, many with the original floor plan still intact. A kitchen in one of these homes was built for a different era: smaller appliance footprints, one or two circuits, and almost no task lighting. When we open walls in Montclair, we routinely find galvanized supply lines, cloth-wrapped wiring, and drain lines that were never sized for a modern dishwasher and garbage disposal.
The climate matters too. Montclair gets hot inland summers, and west-facing kitchens heat up fast in the late afternoon. Remodeling is the right moment to add real ventilation, upgrade insulation, and plan for how heat from the range and oven moves through the house. A kitchen that feels hot and stuffy at 5 p.m. is usually a passive-cooling and ventilation problem, not just an HVAC problem. We plan for that during layout, not after cabinets are installed.
Our Main Montclair Services
Montclair homeowners call us most often about two things: building an ADU on a small lot, and remodeling a bathroom that’s still stuck in its original era. Both jobs demand the same local know-how around setbacks, older plumbing, and tight access. Here’s how each one works in Montclair.
ADU Builders in Montclair
Montclair lots are small, and many garages sit at the rear of the property with alley access. That makes garage conversion the dominant ADU strategy in this city, though detached rear-yard units also work where the setbacks allow. We evaluate the lot, check utility routing, and match the project to one of seven prefab manufacturers or go site-built if that fits better. From foundation to finished kitchen, it’s one team and one contract. See ADU Builders in Montclair for how we handle these projects in this specific city.
Bathroom Remodeling in Montclair
Bathrooms in Montclair’s post-war homes are usually small, with the original cast-iron tub, a single vanity, and floor tile set over plywood that has seen five decades of moisture. We handle the whole remodel in-house: demo, plumbing, waterproofing, tile, and fixtures. No subcontracted crews. On Montclair lots, a bathroom remodel often shares the same drain and vent lines as the kitchen, so scheduling both at once can save money. Read Bathroom Remodeling in Montclair for the full breakdown.

Kitchen Remodeling in Montclair
Kitchen remodeling in Montclair generally means taking a closed-off, single-wall or L-shaped kitchen in a 1950s-to-1970s tract home and opening it up without compromising the structure. These homes were built with load-bearing walls between the kitchen and living room, so removing a wall usually means adding a beam or header. The climate drives decisions too: Montclair’s hot inland summers call for ventilation, heat-conscious appliance placement, and materials that don’t warp or swell. Most Montclair kitchens we remodel need panel upgrades, since the original 100-amp service can’t handle a modern induction range, microwave, and dishwasher at once.

Full Kitchen Remodel
Signs you need it
The layout still works against you: one person can cook, the refrigerator blocks a doorway when open, and there’s no room for two people to pass.
What it costs in Montclair
A full kitchen remodel in Montclair typically runs $35,000 to $65,000, depending on whether walls move and how far the plumbing has to shift.
How we do it
We demo to studs, re-route plumbing and electrical, patch the slab or floor, rebuild the layout, then install cabinets, counters, appliances, and finishes in sequence with our own crew.
Cabinet Replacement and Refacing
Signs you need it
Door hinges are failing, drawer slides bind, or the boxes have absorbed decades of grease and moisture but the layout itself still works.
What it costs in Montclair
Cabinet replacement and refacing in Montclair typically runs $8,000 to $20,000, with the final number depending on linear footage and whether the boxes can be saved.
How we do it
We measure the existing layout, order doors and drawer fronts or full boxes to fit, then swap them out and adjust hardware so every drawer glides clean.
Countertop and Backsplash Upgrade
Signs you need it
Your countertops are chipped, stained, or dated, and the backsplash is original tile that has lost its grout.
What it costs in Montclair
A countertop and backsplash upgrade in Montclair typically runs $4,000 to $12,000, depending on material choice and total square footage.
How we do it
We template the existing counters, pull the old surface, reinforce the base cabinets, and install the new stone or solid surface with the backsplash in one pass.

Most full kitchen remodels in Montclair take six to ten weeks from demo to final walkthrough, depending on cabinet lead times and what the walls reveal. A cabinet or countertop-only job can finish in two to three weeks. Call (877) 265-9846 for a schedule based on your actual scope.

Yes. Montclair enforces California ADU law but still requires local permits for structural, electrical, plumbing, and mechanical work. Kitchen remodels that move gas lines or walls need plan review too. We handle the entire permit package and schedule inspections with the city. The permit process in Montclair is straightforward for compliant scopes, but utility easements and setback compliance can add plan-review time.

What Montclair Customers Say
"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
