Fast, Reliable Home Remodeling Across Alum Rock
Home remodeling in Alum Rock runs anywhere from $5,000 for a single-bathroom refresh to $220,000 for a full ADU build, with most mid-sized kitchens landing between $14,000 and $45,000. What makes Alum Rock different from the incorporated San Jose neighborhoods ten minutes down Alum Rock Avenue is the permitting path: you’re in unincorporated Santa Clara County, which changes how every permit gets pulled, inspected, and signed off. We know those county requirements cold because we work them constantly on the older mid-century homes and slope-adjacent parcels that define this part of the 95127 ZIP. If you’re planning a remodel, addition, or garage conversion, call Noel and our team at (866) 472-1908 and we’ll tell you exactly what your project needs before you sign anything.
Why San Bruno Construction Is Alum Rock’s Preferred Home Remodeling Company
We’ve earned our reputation in Alum Rock by being honest about what a remodel actually takes on these older, unincorporated parcels. Homeowners around the Alum Rock Avenue corridor and up toward the foothills call us because we handle the county-versus-city permit question before it becomes a change order. We coordinate every licensed trade from demolition to final paint, so you’re not chasing three different subcontractors while the county inspector is standing on your driveway. Our clients in Alum Rock consistently tell us the same thing: the quote matched the final invoice, and someone actually answered the phone when the framing inspection got moved.
Noel Carvalho runs our Alum Rock projects with a general contractor’s eye for sequencing. That matters on hillside lots where drainage, retaining walls, and foundation work have to be scoped before the pretty stuff. We bring access to more than 50 vetted product brands, so the budget discussion is never forced into whatever a subcontractor prefers to install. You get real options from KraftMaid, Wellborn, Cambria, and Silestone, and we coordinate delivery so materials arrive when the crew is actually ready for them, not three weeks early or two weeks late.

Home Remodeling Companies in Alum Rock
Home Remodeling Companies in Alum Rock fall into two camps: city-based outfits that treat this neighborhood like any other San Jose jobsite, and contractors who actually understand that 95127 is unincorporated county land with a different set of rules. We’re the second kind. A remodel here starts with confirming jurisdiction, checking the parcel for old additions that were never permitted, and looking at the drainage and slope conditions before we quote a single cabinet pull. That upfront work saves you from the classic Alum Rock surprise, which is discovering halfway through the demo that your rear addition needs legalization sign-off before the county will pass the rough inspection.
Most Alum Rock remodels on mid-century homes run $14,000 to $45,000 for a kitchen, $9,000 to $28,000 for a bathroom, and $45,000 to $130,000 for a home addition. The range is wide because a 1960s stucco-and-wood-frame house with original wiring and no shear wall costs more to open up than a home that got a panel upgrade in the 1990s. We scope all of that before you sign.
Permit Scoping and Legalization
Before we write the contract, we pull the county records, walk the property, and flag anything that was built without sign-off. Legalizing an old unpermitted addition is a standard part of our Alum Rock remodels, and we budget the inspection fees, engineering, and corrections into the original scope of work.
Hillside and Drainage Work
On slope-adjacent parcels, the remodel quote has to include foundation drainage, grading, and sometimes retaining-wall repair. The first winter storm will expose any corner you cut on drainage, and by then the subfloor and drywall are already in. We do the drainage work first, not as an afterthought.
Whole House Remodel in Alum Rock
A Whole House Remodel in Alum Rock is rarely just a cosmetic update. On the older parcels off Alum Rock Avenue and up toward the hills, it’s usually a structural rework: opening load-bearing walls, replacing the panel, addressing water intrusion at the foundation, and bringing square footage up to county code while you’re already in the walls. Whole-home remodels on these mid-century homes typically run between $45,000 and $130,000 depending on square footage, structural corrections, and material choices from lines like KraftMaid for cabinetry and Cambria for countertops. The number moves fast when engineering comes into play, so we scope the structural requirements during our first site walk, not after demo starts.
On a slope-adjacent parcel off Alum Rock Avenue, our crew opened up a 1960s stucco-and-wood-frame kitchen remodel and found the rear addition had never been permitted. We scoped the legalization into the same scope of work, pulled the county permits, and got inspection sign-off on the new rough-in before the drywall closed. We set allowances in writing for KraftMaid cabinetry and a Cambria countertop so the change order stayed clean when the load-bearing wall needed a beam.
Sequencing on Occupied Homes
When you’re living in the house during a whole-home remodel, the sequence matters more than anything. We phase the work so you always have a functioning bathroom and a place to cook, and we keep the site locked and swept at the end of every day.
Structural Corrections Before Finish Work
Older Alum Rock homes often need shear-wall reinforcement, beam replacement, or foundation repairs behind the drywall. We open the walls, show you what’s there, and get the structural sign-off before a single cabinet or countertop gets installed.
Trusted Brands We Service in Alum Rock
We stock and coordinate the brands our Alum Rock customers actually ask for, including KraftMaid and Wellborn cabinetry and Cambria and Silestone countertops. Because these homes are older and often have non-standard openings, we measure twice and order once, with real lead times built into the schedule. Our supplier relationships among 50-plus vetted brands mean we can offer premium and mid-range options without the markup games, and replacement parts show up fast when a hinge or a stone slab needs to be reordered. That keeps your Alum Rock project moving instead of stalled on a backordered drawer front.

AfterCommon Home Remodeling Problems We See in Alum Rock Homes
- County-versus-city permit confusion. Alum Rock sits in unincorporated Santa Clara County, which means a remodel that would go through San Jose permitting a mile west goes through county channels instead. Contractors who don’t check jurisdiction first end up with stalled inspections and angry homeowners.
- Unpermitted additions from decades past. The mid-century homes here often have second units, bumped-out kitchens, or enclosed patios that were built informally long ago. A remodel frequently turns into a legalization job, and that requires separate inspection sign-off from the county.
- Hillside water intrusion after winter storms. The steep hills above Alum Rock shed water fast, and the first storms of the year expose foundation seepage, erosion, and retaining-wall problems. If drainage wasn’t scoped before the remodel, the water finds the new subfloor.
- Long material hauls and tight access. Many Alum Rock parcels sit on long, steep driveways where a standard delivery truck can’t turn around. We plan material drops and equipment access before the draw schedule is set, so cabinets and countertops don’t arrive on a truck that can’t reach the house.

FAQs About Home Remodeling in Alum Rock
You need a Santa Clara County permit because Alum Rock is unincorporated county land, not part of the incorporated City of San Jose. The county has its own plan-check, inspection, and sign-off process that differs from the city’s. We confirm jurisdiction and handle the full county permitting path on every Alum Rock project. Call (866) 472-1908 and we’ll tell you exactly which agency has authority over your parcel.
Yes, and we do it often. The remodel scope includes legalizing the old addition through county inspection, which means exposing the work, correcting whatever doesn’t meet code, and getting it signed off before the new rough-in closes. We budget the legalization into the same contract so it’s not a surprise change order. Call (866) 472-1908 to have us pull the records and tell you what your specific property needs.
We scope foundation drainage, surface grading, and any retaining-wall repairs before we touch the interior finishes. Water from the steep hills above Alum Rock moves fast in the wet season, so drainage gets addressed as the first phase of work. We’d rather catch a drainage problem before the subfloor goes down than after the first winter storm. Call (866) 472-1908 for a free site evaluation.
Yes, including prefab ADUs from brands like Abodu, Dvele, Mighty Buildings, Boxabl, and Plant Prefab. Detached structures on unincorporated acreage involve county setbacks, septic and well-spacing requirements, and access planning for material deliveries, all of which we scope before you sign a contract. We coordinate the full build, including the prefab delivery and site prep. Call (866) 472-1908 to talk through what fits on your parcel.
The single biggest dispute prevention is scoping the permit path, legalization work, drainage, and access before the contract is signed. We write allowances in the contract for major material selections like KraftMaid cabinetry and Cambria countertops, so when a load-bearing wall needs a beam in an older home, the change is already accounted for. Call (866) 472-1908 and we’ll show you what a properly scoped Alum Rock remodel quote looks like.
