ADU Company in Montclair, CA
Kitchen remodeling in Montclair usually runs $35,000 to $85,000 for a full gut renovation, with most of our clients in the 91763 ZIP taking three to six weeks from demo to final walkthrough. Montclair homes built between the 1950s and 1970s bring a distinct set of conditions: post-tension slabs, original galvanized plumbing, and stucco walls that hide surprises until you open them up. We’re Home Base ADU Builders, and we’ve served Montclair since 2016, matching homeowners to the right remodel scope rather than a one-size quote. Call (866) 403-9834 for a free estimate that reflects your actual house, not a regional average.
Why Montclair Homes Are Different
Montclair sits entirely within the 91763 ZIP at the foot of the San Gabriel Mountains, and the housing stock reflects a specific era of San Bernardino County growth. Most homes went up between the 1950s and 1970s as modest single-story stucco tract houses on unusually generous lots. The deep backyard setback is the ADU asset here, but for kitchen work, the lot size matters less than what’s inside the walls. Original copper supply lines and cast-iron drain stacks are reaching the end of service life, and older 100-amp electrical panels often need an upgrade before any modern kitchen can pass inspection.
The climate adds another layer. Inland Empire foothill summers push toward 100°F, and the dry Santa Ana wind events mean kitchens get harder use than coastal homes: refrigeration runs longer, exhaust systems pull more air, and finish materials need to handle temperature swings. Countertop selection matters in ways it doesn’t in Claremont or Upland’s newer stock. We also see a consistent pattern in Montclair kitchens: original footprint, no ventilation to the exterior, and a soffit above the upper cabinets hiding either ductwork or wasted space. Working around those constraints without wiping out the budget is what separates a Montclair kitchen that works from one that just looks new.
Our Main Montclair Services
Montclair homeowners call us most often about two projects: building an ADU in the backyard and bringing an aging bathroom up to standard. Both require the same core skill: working inside houses that predate modern code without turning every job into a full rebuild.
ADU Builders in Montclair
Montclair’s detached garages at rear corners and the deep flat lots behind mid-century tract homes create a particular ADU opportunity: a new detached unit along the rear property line, connected to a garage you still use for parking. The pre-1978 construction date on most Montclair homes means any garage conversion triggers lead and asbestos handling requirements, which is why we scope carefully before quoting. Montclair’s lack of an alley system means rear ADUs run into second-story privacy negotiations with neighbors, and the wildland-urban interface near the foothills can bring defensible-space roofing requirements. We match the build method to the lot: Tuff Shed-based conversions for budget paths, Dvele or Abodu prefabs for premium detached units. ADU Builders in Montclair covers the full comparison.
Bathroom Remodeling in Montclair
Montclair bathroom remodels often involve the same pre-1978 conditions as kitchens: original cast-iron waste lines, failing shower pans, and wall tile set over drywall rather than cement board. The hot, dry Inland Empire climate means ventilation upgrades do more here than in coastal cities, since trapped moisture leads to mold faster in a house that already runs warm. We finish bathrooms with the same James Hardie fiber-cement thinking we use on ADU exteriors: materials that handle temperature swings without warping or degrading. Bathroom Remodeling in Montclair has the full scope for that work.

Kitchen Remodeling in Montclair
Kitchen remodeling in Montclair most often means working inside a 1950s-to-1970s tract home where the original kitchen footprint still has the old soffit, no exterior venting route, and a slab foundation that makes relocating the sink or gas line a real cost decision, not a simple swap. In the hot foothill summers, exhaust ventilation and appliance placement matter more than in coastal cities, because a kitchen that can’t move heat out becomes unusable by July. Kitchen Remodeling is the full service hub to see how we handle the build end to end.
Gut Renovation with Layout Change
Signs you need it
The existing layout traps you against the refrigerator when the dishwasher door is open, or the kitchen has no path to a dining area without walking through an appliance swing zone.
What it costs in Montclair
Full layout changes typically run $55,000 to $85,000 in Montclair because slab work for moving plumbing and the panel upgrade for new appliances both hit that era of tract home.
How we do it
We demo to the studs, reroute plumbing and electrical with permits pulled, open the layout, install the new cabinet run and counters, then finish with flooring and paint through final inspection.
Cabinet and Countertop Update
Signs you need it
The cabinet boxes are sound but the doors sag, the counters are laminate that’s delaminating at the seams, and you want a different material without changing the footprint.
What it costs in Montclair
Cabinet and countertop refreshes usually land between $35,000 and $55,000 depending on material grade, with quartz and stone pushing toward the upper end.
How we do it
We measure the existing footprint, order the new doors or full boxes, replace counters with the material you selected, and install the finished run in place without touching the slab.

Does a kitchen remodel in Montclair require a permit?
Yes. Any change to electrical, plumbing, or the gas line requires a city permit in Montclair. We pull those permits and handle the inspections. Call (866) 403-9834 to learn what your specific scope will trigger.
Will moving my sink or gas line drive up the cost?
Yes, because Montclair’s slab foundations mean cutting concrete to relocate plumbing, and most 91763 homes need a panel upgrade for the added load. Call (866) 403-9834 for a line-item quote before you commit to a layout.

What Montclair Customers Say
"Knew the local setback and parking rules cold, which saved us from designing something that would never have been approved."
— Priya Mehta"Sound insulation between the unit and the main house is better than I expected. You genuinely cannot hear the tenant."
— Luis Garcia"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."
— Robert Hayes
