ADU Company in Montclair, CA
Kitchen remodeling in Montclair usually means working inside a 1950s or 1960s single-story stucco home where the original galley kitchen was built for a different era of living. Most of these homes have never been structurally updated, so we regularly open walls to find single-zone wiring, cast-iron drain lines, and framing that needs reinforcement before new cabinets go in. We handle the full kitchen scope in-house, from demolition to finish plumbing and electrical. If you’re planning an ADU at the same time, we coordinate both projects so the kitchen and the new unit share one schedule and one responsible team. Call (866) 538-0916 to talk through what your Montclair kitchen needs.
Why Montclair Homes Are Different
Montclair is built out almost entirely of post-war tract homes, and that single fact shapes every kitchen remodel we do here. The lots are modest, typically around 6,000 square feet, and the houses are single-story stucco with the kitchen tucked into the middle or rear of the floor plan. What that means in practice: load-bearing walls are common, ceiling heights are often a tight 8 feet, and the original electrical panel is usually a 100-amp unit that was never designed for modern appliances, induction cooktops, or the mini-split systems many Montclair homeowners want now.
The climate adds another layer. Inland San Gabriel Valley summers push well into the 90s and 100s, so a kitchen remodel here isn’t just about cabinets and counters. Ventilation matters. A range hood that actually moves air matters. And if you’re converting a detached garage into an ADU and adding a kitchenette, that older slab and uninsulated framing mean the mechanical work has to be planned carefully before finishes ever start. Homes off Holt and Arrow, especially the older blocks with alley-loaded rear garages, tend to have the tightest layouts and the most creative remodeling opportunities.
Our Main Montclair Services
Montclair homeowners call us most often about two things: building a new ADU on the back of the lot, and remodeling the bathroom inside the main house. Both jobs pull from the same in-house crews and the same understanding of how these 1950s and 1960s homes are put together.
ADU Builders in Montclair
Montclair is a garage-conversion city. The detached rear garage, accessed by an alley or a long driveway, is usually the only viable ADU footprint on these modest lots. We work with that reality: older slabs that need leveling, uninsulated framing that needs a full thermal envelope, and single-zone wiring that has to be separated and upgraded. Whether the project is a ground-up unit or a Tuff Shed-based conversion, we handle the planning, permits, and build through one team. ADU Builders in Montclair covers the full scope for this city.
Bathroom Remodeling in Montclair
Original Montclair bathrooms are small, often 5 by 8 feet, with cast-iron tubs and single-sink vanities. When we remodel them, the usual questions are whether to keep the tub, how to add storage without expanding the footprint, and how to bring ventilation up to code for a house that gets this hot. We handle the entire bathroom scope in-house, which matters when the same crew is also finishing an ADU on the property. Bathroom Remodeling in Montclair explains what a typical project involves.

Kitchen Remodeling in Montclair
Most Montclair kitchens are original galley layouts, around 10 by 12 feet, with a load-bearing wall on one side and a window over the sink facing the side yard. The job here almost always starts with the mechanicals: upgrading the 100-amp panel, replacing cast-iron drain lines, and adding dedicated circuits for a modern appliance package. Because summer heat is relentless, we also plan for a real ventilation hood and, in many cases, a mini-split or ducted cooling upgrade so the kitchen stays usable in August. We bring the full Kitchen Remodeling scope to Montclair: design, demolition, framing, plumbing, electrical, cabinetry, countertops, and finish work under one roof.
Full Gut Renovation
Signs you need it
The original cabinets are delaminating, the floor has soft spots near the sink, or you can see single-zone wiring feeding every outlet in the room.
What it costs in Montclair
A full gut renovation of a Montclair kitchen typically runs $55,000 to $85,000 depending on layout changes and appliance choices.
How we do it
We strip the room to studs, upgrade the electrical and plumbing, reframe for load-bearing changes, then rebuild with new insulation, drywall, cabinetry, counters, and finishes.
Cabinet and Countertop Replacement
Signs you need it
The cabinet boxes are solid but the doors are worn, or the layout works and you just want a surface upgrade without moving walls.
What it costs in Montclair
A cabinet and countertop replacement in Montclair typically runs $18,000 to $35,000 depending on material grade and linear footage.
How we do it
We remove the old doors, boxes where needed, and countertops, then install new cabinetry, stone or quartz surfaces, a tile backsplash, and a fresh sink and faucet.

Two things push kitchen remodel prices up in Montclair: the electrical panel upgrade that almost every 1950s home needs, and any structural work on load-bearing walls when homeowners want to open the kitchen to the living area. We give you a fixed, written line-item quote before work starts, and that number does not change unless you add scope.

A full gut renovation in Montclair usually takes 6 to 10 weeks from demolition to final walkthrough. Cabinet and countertop replacements run 3 to 5 weeks on average. Call (866) 538-0916 to schedule a free estimate and we’ll give you a realistic timeline for your specific kitchen.
Do you pull permits for a Montclair kitchen remodel?
Yes. We handle the full permit package with the City of Montclair, including electrical and plumbing permits. Any remodel that moves plumbing or adds circuits requires city inspection, and we schedule and pass those inspections as part of the job. Call (866) 538-0916 for a free estimate that includes permit costs.
Brands We Service in Montclair
We work across the full spectrum of construction methods, so the brand conversation starts with what fits your lot and budget. For Montclair garage conversions, Tuff Shed structures are a practical starting point when the existing slab and framing are sound. For ground-up ADUs on a cleared back lot, Boxabl and Plant Prefab offer factory-built precision that shortens on-site time. We finish exteriors with our brands including James Hardie siding and trim, which holds up to the Inland Empire sun better than standard fiber cement alternatives.

In Montclair, the biggest price driver on ADU work is the condition of the existing detached garage: older slabs that have settled, single-zone wiring that needs a full re-feed, and the lot-coverage math on narrow 6,000 square foot parcels. Whatever the scope, we quote a fixed price before we start and we do not hit you with change orders for work we already inspected.

What Montclair Customers Say
"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."
— Vikram Sharma"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."
— Heather Rhodes"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
