ADU Company in Montclair, CA
Kitchen remodeling in Montclair means working inside homes built mostly between the 1950s and 1970s, where original layouts, older wiring, and 100-amp panels are the norm rather than the exception. We’re Casita ADU Builders, and while ADU construction is our core work, our in-house kitchen remodeling crew handles the interior side of things so a garage conversion or backyard unit finishes as a complete, livable home. Montclair’s hot inland summers shape how we plan ventilation, cooling, and materials – and the small-lot reality of this 1.1-square-mile city means every square foot of a kitchen has to earn its place. Call us at (877) 658-7475 to talk through your project.
Why Montclair Homes Are Different
Montclair’s housing stock is overwhelmingly mid-century stucco tract homes on compact lots, many platted in the 1950s and 60s when a two-car garage and a modest kitchen were plenty. That era shows up in the work we do: original galvanized plumbing that has seen better decades, electrical panels sized for a different appliance load, and kitchen footprints that were not designed for today’s peninsula-and-island expectations. The climate adds another layer. Summers in this part of the San Gabriel Valley run hot and dry, with Santa Ana wind events that push dust and heat against west-facing walls. A kitchen remodel here should account for real cooling loads, which often means a dedicated circuit for a window or mini-split unit, plus finishes that hold up to temperature swings without swelling or separating.
The lot geometry drives decisions too. Montclair is largely built out, which means most kitchen projects happen inside homes where the garage sits close to the rear property line and the house fills most of its parcel. When a kitchen remodel pairs with an ADU conversion on the same lot, setback and lot-coverage questions land on the same permit counter visit. We have learned to plan both scopes together so the kitchen work does not trigger a surprise parking-replacement review or a utility-capacity problem that could have been caught at the start. That is the kind of local knowledge that saves Montclair homeowners real money and weeks of delay.
Our Main Montclair Services
Montclair homeowners call us about two things more than anything else: adding an ADU to a lot that is already mostly spoken for, and remodeling the bathrooms inside homes that have not changed since the Eisenhower and Nixon years. Here is how each works in this city.
ADU Builders in Montclair
Every Montclair ADU project starts with the same question: can this lot take a second unit without running into the 4-foot rear setback or a parking-replacement review? Most of the time the answer is yes, and the path is a garage conversion or a compact rear-yard unit built to match the existing home’s stucco lines. We work across prefab brands including Abodu, Cover, and Dvele, and we also handle Tuff Shed conversions for homeowners who want a faster, lower-cost route. Because Montclair’s lots are tight and often fully developed, the utility-capacity question (usually the 100-amp panel and the sewer lateral) is the first thing we check. ADU Builders in Montclair covers the full build process, from site assessment to final inspection.
Bathroom Remodeling in Montclair
Bathrooms in Montclair’s 1950s-70s tract homes were built small, and they were built to a standard that did not anticipate a family of four sharing one shower. We regularly see original cast-iron tubs, tile-over-mortar walls, and exhaust fans that vent into the attic instead of outside. Our bathroom work in Montclair focuses on layouts that make a small footprint work harder, ventilation that actually moves humid air out of the house, and finishes that tolerate inland heat without cracking grout lines. When the bathroom is part of an ADU, we size the rough-in, water heater, and venting to the unit’s actual load, not the main house’s. Bathroom Remodeling in Montclair walks through the options and the typical scope.

Kitchen Remodeling in Montclair
Kitchen remodeling in Montclair usually means untangling sixty years of piecemeal updates inside a house that was built with a single wall of cabinets, a 30-inch range, and no dishwasher. The typical Montclair kitchen sits on a slab foundation with original plumbing in the floor, so moving a sink or adding an island often means cutting concrete – which is why we plan the layout around what is already there unless a full reconfiguration is the whole point. Our in-house kitchen crew handles everything from demo to finish, so a kitchen inside an ADU or a main house gets the same subcontractor-free process and the same single contract. Kitchen Remodeling is our dedicated kitchen hub, and the sections below cover what Montclair homeowners ask us about most.
Full Kitchen Renovation
Signs you need it
You are working around a layout that fights you every time you cook, with cabinets that predate standard dimensions, countertops that have outlived their surface, and an electrical setup that trips a breaker when the microwave and toaster run at the same time.
What it costs in Montclair
A full kitchen renovation in Montclair typically lands between $28,000 and $55,000, with the spread driven by cabinet choice, countertop material, and how much electrical or plumbing work the original 1950s-70s structure requires.
How we do it
We open the walls enough to see what the framing and rough-ins actually look like, design the new layout around Montclair’s slab-on-grade reality, then demo, rough in, and finish under one crew and one schedule.
Cabinet Refacing and Countertop Replacement
Signs you need it
Your cabinet boxes are solid but the faces are dated, yellowed, or delaminating, and your countertops have burns, stains, or seams that have failed after decades of inland heat cycles.
What it costs in Montclair
Cabinet refacing and countertop replacement in Montclair runs $9,000 to $18,000 depending on door style, finish, and square footage of countertop.
How we do it
We reface the existing cabinet boxes with new doors and drawer fronts, remove and replace the countertops with a material rated for heat and wear, and reseat the sink and fixtures to factory spec.
What Kitchen Remodeling Costs in Montclair
| Item | Typical range in Montclair |
|---|---|
| Full kitchen renovation | $28,000 – $55,000 |
| Cabinet refacing + countertop replacement | $9,000 – $18,000 |
| Kitchen electrical upgrade (panel, circuits) | $2,500 – $6,000 |
Prices in Montclair shift most based on whether the original slab plumbing stays put, whether the 100-amp panel needs an upgrade to carry a modern appliance load, and whether the kitchen shares a wall with a garage conversion ADU that is being permitted at the same time. Every estimate we give is a written, line-item quote, and the price we quote is the price you pay unless you change the scope.
Can you remodel a kitchen and build an ADU on the same Montclair lot at the same time?
Yes, and doing both under one contract actually reduces coordination risk. We sequence the kitchen work around the ADU rough-in so the panel upgrade, sewer capacity, and lot-coverage review are handled once instead of twice. Call (877) 658-7475 to talk through your lot.
How long does a kitchen remodel take in Montclair?
Most Montclair kitchen remodels take 4 to 8 weeks depending on scope, with cabinet refacing running shorter and full layouts with slab plumbing changes running longer. Permitting adds about 2 to 4 weeks on top. Call (877) 658-7475 for a timeline based on your specific scope.
Brands We Service in Montclair
We service ADU builds from Abodu, Cover, and Dvele, and we use James Hardie fiber-cement siding on exterior applications because it holds up to Montclair’s summer heat and Santa Ana wind without warping or fading. Parts and finishes are ordered and staged locally for Montclair projects to keep turnaround tight. Our brands page covers the full manufacturer lineup and what each one does best.

FAQs About ADU Company in Montclair
We schedule Montclair site visits within one business day of your call. We meet you on-site, walk the lot or the interior, and talk through scope, access, and what is realistic for your specific home era and lot size. Call (877) 658-7475 to set a time.
Most Montclair projects require standard building permits through the city, and ADU work on narrow lots often triggers a setback, lot-coverage, or parking-replacement check at the counter. We handle permit drawings, submittal, and inspection coordination as part of the contract, so you are not the one figuring out a 4-foot rear setback question on a 1950s lot.
Yes. That is exactly how our model works. The prefab shell arrives, and our in-house kitchen and bathroom crews finish the interior under the same contract and the same project manager, so you are not coordinating a manufacturer, a shell contractor, and a separate finish crew. Call (877) 658-7475 for a free estimate on your Montclair project.

What Montclair Customers Say
"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."
— Aisha Prince"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Maria Martinez"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."
— Arjun Singh
