ADU Company in Montclair, CA
Kitchen remodeling in Montclair usually means reworking a 1950s or 1960s galley kitchen inside a tract home that was never designed for the way families cook today. Fullerton ADU Builders has served Montclair since 2017, and we’ve learned that these older homes hide surprises behind the drywall: undersized electrical, cast-iron drain lines, and load-bearing walls that sit right where homeowners want an open plan. We handle the whole job, from the first demo pass to the final cabinet pull, and we coordinate with the same city planning counter that Montclair homeowners deal with on ADU permits. Call (877) 801-4497 to schedule a free estimate.
Why Montclair Homes Are Different
Montclair is a small, fully built-out city in the Pomona Valley. Nearly all single-family lots in 91763 date to the post-WWII boom, which means the housing stock is predominantly 1950s to 1970s single-story tract homes with detached or attached one- and two-car garages on narrow lots. That changes the work. A kitchen remodel here is almost never a clean tear-out on a blank canvas. We’re working around load-bearing walls that were framed with old-growth lumber, subpanels that were installed when a kitchen had two countertop outlets, and floor plans that split the kitchen off from the living space with a wall the homeowner now wants gone.
Inland Pomona Valley heat shapes the choices too. A Montclair kitchen that faces west or south bakes in the afternoon, so we pay attention to window placement, range hood ventilation, and whether the refrigerator is fighting a sun-loaded wall. Narrow side yards and long driveways are common in these older tracts, which matters when we’re staging deliveries for cabinets, appliances, and countertop slabs. Sometimes a slab has to be carried in from the driveway because a crane or flatbed can’t reach the back. And every permit runs through the city as a case-by-case review on a 1950s tract parcel, not a by-right formality. That’s simply how Montclair works, and we plan for it from the first site visit.
Our Main Montclair Services
Montclair homeowners call us about two projects more than anything else: adding an accessory dwelling unit to an already-paved lot, and renovating a bathroom in a house where the plumbing is original. Both are covered here, with dedicated pages for each.
ADU Builders in Montclair
ADU work in Montclair is almost never on empty land. It’s squeezing a detached unit or a garage conversion onto a tight, already-paved lot, and every project runs through a city planning counter that treats ADUs as a case-by-case overlay on 1950s tract parcels rather than a by-right formality. We’ve handled that process enough times to know what Montclair’s reviewers look for, from setback interpretations on narrow side yards to utility connection points that are older than the homeowner.

Bathroom Remodeling in Montclair
Bathroom remodels in these homes often mean replacing cast-iron drain lines and galvanized supply pipes while the walls are open. That’s normal for 1950s and 1960s tract construction in Montclair, and it’s exactly the kind of condition a generalist contractor misses until the tile is already off. Our scope covers the full bathroom: tub or shower replacement, vanity and counter, lighting and exhaust, and flooring. We match the finish level to the house and the neighborhood so the remodel feels like it belongs. See the dedicated page for local pricing and timelines. Bathroom Remodeling in Montclair

Kitchen Remodeling in Montclair
Kitchen remodeling in Montclair is the single highest-impact upgrade you can make to a 1950s or 1960s tract home. The kitchens in these houses were built small and closed off, with minimal counter space, no room for a dishwasher, and electrical service that predates modern appliance loads. Inland heat pushes those rooms hard in the summer, especially when a west-facing wall turns the kitchen into the hottest room in the house. We rework the layout, upgrade the electrical and plumbing, and specify materials that hold up to the Pomona Valley climate: James Hardie fiber cement exteriors on adjacent walls where we’re adding square footage, proper range hood ventilation, and insulation that actually handles a 95-degree afternoon. Fullerton ADU Builders brings the same brand-agnostic approach to kitchens that we use on ADUs, meaning we match the materials and layout to your house and how you cook, not to a showroom’s inventory. For the full service breakdown, see Kitchen Remodeling.
Galley Kitchen Layout Changes
Signs you need it
Your Montclair kitchen is a long, narrow galley with one narrow path, no landing space near the stove, and a refrigerator that blocks the back door when it’s open.
What it costs in Montclair
A galley kitchen rework in Montclair typically runs $25,000 – $45,000, depending on how much of the existing wall structure has to stay and how far we have to move the plumbing or electrical.
How we do it
We map the load path, open the wall where it’s safe, move the sink and range to create a working triangle, and rebuild the cabinet run with deeper lower cabinets and full-height uppers that fit the existing footprint.
Kitchen Electrical and Ventilation Upgrade
Signs you need it
Your Montclair kitchen has two-prong outlets, one overhead light, and a range hood that just blows air back into the room or vented to nowhere.
What it costs in Montclair
An electrical and ventilation upgrade for a 1950s or 1960s Montclair kitchen typically falls between $8,000 and $15,000, depending on panel capacity and how far the vent run has to travel to reach an exterior wall.
How we do it
We replace the subpanel feed if needed, add dedicated circuits for the range, refrigerator, dishwasher, and countertop outlets, then run a properly ducted range hood to the exterior with a damper that handles Pomona Valley heat.
Full Kitchen Gut and Rebuild
Signs you need it
The kitchen floor has sagged, the cabinets are separating from the walls, and the plumbing and electrical are a patchwork that no longer meets Montclair’s current code requirements.
What it costs in Montclair
A full gut and rebuild in Montclair runs $45,000 – $70,000, including new subfloor where needed, all rough-in work, drywall, paint, cabinets, counters, and finish plumbing and electrical.
How we do it
We strip the room to the studs, replace the damaged framing and subfloor, re-rough the plumbing and electrical to current code, then rebuild with insulation rated for inland heat, a new window or two for cross-ventilation, and finishes matched to the rest of the house.
What Kitchen Remodeling Costs in Montclair
| Item | Typical range in Montclair |
|---|---|
| Galley kitchen layout change | $25,000 – $45,000 |
| Electrical and ventilation upgrade | $8,000 – $15,000 |
| Full kitchen gut and rebuild | $45,000 – $70,000 |
How long does a kitchen remodel take in Montclair?
A typical Montclair kitchen remodel takes 6 to 10 weeks, with the electrical and plumbing rough-in usually passing inspection by week three. The city’s case-by-case permit review on older tract parcels can add a week or two at the front end, so we file early and build that time into the schedule. Call (877) 801-4497 for an exact timeline on your kitchen.
Will my Montclair kitchen remodel price change once work starts?
Our quotes are fixed for the scope we write down. The price only moves if you change the scope, or if demolition reveals a condition no one could have seen, like a failed cast-iron drain line under the slab, and we walk you through that before any change order is signed. Call (877) 801-4497 for a free estimate.

The two things that push a Montclair price up fastest are the condition of what’s already there: cast-iron drains, undersized panels, and slabs that have shifted in the valley heat. The second is access: when a rear-yard ADU can only be staged from a narrow side yard or a long driveway, that adds crane time and hand-carry labor. We give you a fixed, written line-item price before work starts, and we don’t change it unless you change the scope or we both see something in the ground that no one could have predicted.

What Montclair Customers Say
"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Marisol Guzman"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."
— Greg Reed"Detached unit in the back yard. Utilities trenched, separate meter, and it passed final on the first inspection."
— Erin Ziegler
