ADU Company in Montclair, CA
Kitchen remodeling in Montclair usually means working inside a 1950s or 1960s single-story stucco tract home where the original footprint is tight, the plumbing runs through a slab, and the rear of the house faces a detached garage that may one day become an ADU. Bungalow ADU Builders handles both pieces: we remodel kitchens and bathrooms in Montclair, and we build detached ADUs on the same rear-lot footprint those old garages occupy. Call (866) 730-4828 for a free estimate.
Why Montclair Homes Are Different
Montclair’s housing stock is overwhelmingly post-WWII single-story stucco, built between the 1950s and 1970s on flat lots that run 50 to 60 feet wide. That narrow width is the defining constraint for any ADU project here. The detached garage sits at the rear of the property, often backing onto an alley or shared driveway, and it becomes the natural conversation starter for an ADU conversion or replacement. But those garage slabs were poured as parking pads, not foundations. Many lack the footing depth and reinforcement a habitable structure requires, which means a structural retrofit happens before framing begins.
The other Montclair-specific reality is the slab-on-grade original construction. When we tie an ADU into sewer, water, or electrical, we route around the original main-line laterals rather than tunneling through them. Hot inland summers with triple-digit temperatures and Santa Ana wind events mean insulation and cool roofing are not optional upgrades in Montclair. A small ADU with poor insulation overheats by mid-morning. Winter rains can pool on older rear-lot drainage, so grading gets checked before we place a unit. These are the conditions that shape every estimate we write in 91763.
Our Main Montclair Services
Montclair homeowners call us most about two things: adding an ADU on the rear-garage footprint, and bringing an aging bathroom up to rentable or livable condition. Here is how each works locally.
ADU Builders in Montclair
Most Montclair ADU projects start with the detached garage at the rear of the lot. It is the right footprint, but it sits close to the property line, and the slab underneath usually needs structural work before anything else happens. We work with seven ADU brands, including Abodu, Cover, and Dvele, so the recommendation follows your lot and budget, not a single locked-in product. From foundation retrofit to finished interior, one team handles the entire build. ADU Builders in Montclair covers the full process, from site check to move-in.
Bathroom Remodeling in Montclair
Montclair bathrooms from the 1950s and 1960s are small, and the plumbing sits in a slab, so moving a toilet or shower drain means cutting concrete, not just rerouting pipes through a crawlspace. We plan around that from the first site visit. Our team also finishes the bathrooms inside ADUs we build, so the same crew that frames the unit sets the tile and installs the fixtures. Bathroom Remodeling in Montclair walks through the most common local projects and what they involve.

Kitchen Remodeling in Montclair
A kitchen remodel in Montclair is almost always a workaround project: the original 1950s or 1960s kitchen is small, the plumbing and electrical come up through a slab floor, and the homeowner wants more counter space, better storage, and a layout that actually functions without feeling like a hallway. The heat matters too. Montclair summers push triple digits, so a remodeled kitchen needs ventilation and cooling thought through at the start, not added as an afterthought. We also see a lot of Montclair homeowners remodeling the kitchen inside an ADU before it goes on the rental market, because a livable unit needs a real kitchen, not a hot plate and a mini fridge. Kitchen Remodeling is a core service for us, and it is often the project that turns a garage conversion into a rentable home.
Full Kitchen Remodel
Signs you need it
Cabinets are original to the house, the layout forces two people to squeeze past each other, and the counters are too low or too shallow for modern appliances.
What it costs in Montclair
A full kitchen remodel in Montclair typically runs $28,000 to $65,000 depending on cabinet grade, countertop material, and whether walls or plumbing lines move.
How we do it
We start with a site visit to map the existing slab plumbing and electrical, design the new layout around what can move without excessive concrete cutting, then build the kitchen in phases with finished carpentry and appliance installation done by our own crew.
Kitchen Cabinet Refacing
Signs you need it
The cabinet boxes are solid and square, but doors are warped, hinges sag, and the finish has worn through in high-touch areas.
What it costs in Montclair
Cabinet refacing in Montclair runs $7,000 to $16,000, which is usually half or less than the cost of replacing the entire cabinet run.
How we do it
We remove and replace doors, drawer fronts, and hardware, then apply a new veneer or paint finish to the existing boxes so the kitchen looks new without tearing out the frame and disturbing slab plumbing.
What Kitchen Remodeling Costs in Montclair
| Item | Typical range in Montclair |
|---|---|
| Full kitchen remodel | $28,000 – $65,000 |
| Kitchen cabinet refacing | $7,000 – $16,000 |
| Countertop replacement | $3,500 – $9,500 |
What pushes a Montclair kitchen remodel toward the upper end is usually slab work: moving a sink or gas line a few feet means cutting and patching concrete, which adds labor and time. We price the job upfront with a written, line-item quote, and the number you sign is the number you pay.
How long does a kitchen remodel take in Montclair?
A full kitchen remodel in Montclair usually takes 4 to 8 weeks. Slab plumbing changes, cabinet lead times, and countertop fabrication add the most time. We give you a schedule at contract and update it as each phase closes.
Can you remodel the kitchen inside an ADU at the same time as the build?
Yes. Because we handle the ADU shell and the interior finishes under one company, the kitchen goes in as part of the same schedule, not as a separate contractor handoff. Call (866) 730-4828 to talk through the combined scope.
Brands We Service in Montclair
We source from the ADU brands Montclair homeowners have already researched, including Abodu, Cover, and Dvele. For exteriors we turn to our brands like James Hardie fiber-cement siding because it holds up through inland heat and Santa Ana wind better than the cheapest cladding alternative.

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."
— Emily Yang"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Alicia Ingram"The kitchenette layout he suggested made better use of the space than the one on our original sketch."
— Kelly Schaefer
