Remodeling Company in Alum Rock, CA
Home renovation in Alum Rock means working with mid-century stucco-and-wood-frame homes on alluvial fan terrain at the base of the hills, where drainage, retaining walls, and unpermitted additions shape nearly every project. San Bruno Construction has served Alum Rock since 2016 as the single contractor who coordinates every trade, material order, and permit step, so a remodel doesn’t turn into a part-time job for the homeowner. Whether it’s a kitchen update, a hillside retaining-wall repair tied into an addition, or converting a long-ago informal second unit into a legal ADU, we handle the full scope. Call (866) 472-1908 for a free estimate on your Alum Rock project.
Why Alum Rock Homes Are Different
Alum Rock is an unincorporated pocket of east San Jose, and that single fact changes more about a remodel than most homeowners expect. Permits here run through Santa Clara County rather than the city of San Jose, and the county’s review process has its own quirks, especially on older parcels where a garage was converted or a room was added decades ago without paperwork. We regularly start a “simple” kitchen remodel in Alum Rock and end up filing for legalization of a prior addition before the new work can pass inspection.
The housing stock itself is largely 1950s through 1970s stucco and wood-frame, with a scattering of pre-war farmhouses that were grandfathered in when the orchards gave way to subdivisions. Those mid-century homes sit on the alluvial fan below the Alum Rock hills, which means two things: expansive clay soils that move with winter moisture, and stormwater that sheets off the steep slopes above the neighborhood and finds its way into foundations. Foundation seepage, hillside erosion, and retaining-wall failures show up right after the first heavy rains of the season, and any renovation that touches a foundation, a hillside wall, or exterior drainage has to account for that water path.
Many Alum Rock parcels also carry informal second units, attached or detached, that predate current ADU codes. That’s actually an opportunity: legalizing and upgrading those units under today’s ADU rules is often faster than building new, and it adds real value. The catch is the county-versus-city jurisdiction split, which trips up contractors who only work inside San Jose city limits. We know which desk the plans need to land on.
Styles & brands we work with
Our Main Alum Rock Services
Two services account for most of the calls we field from Alum Rock homeowners: full general-contractor coordination on larger jobs, and whole-home or major-room remodeling. Here’s what each looks like on the ground in Alum Rock.
General Contractor in Alum Rock
When an Alum Rock project spans multiple trades – say a kitchen that flows into a roofline repair, or a garage conversion tied to a new retaining wall – someone has to own the schedule, the permit file, and the material orders. That’s the general contractor role, and on unincorporated county parcels it matters even more, because the county wants one responsible party on the paperwork. We coordinate the licensed trades, sequence the work around Alum Rock’s wet-season drainage issues, and keep the project moving without the homeowner playing phone tag with five different crews.

Home Remodeling in Alum Rock
Mid-century Alum Rock homes have good bones but dated layouts: closed-off kitchens, single bathrooms doing too much work, and additions that were never properly tied into the roofline or foundation. A remodel here means reworking those spaces while respecting what the stucco and wood-frame structure can carry, especially on slope-adjacent lots where foundation work is common. We plan the remodel around the county permit path from day one, so a project that starts as a kitchen update can absorb a bedroom addition or a legalized second unit without stalling.

Home Renovation in Alum Rock
Home renovation in Alum Rock is rarely a one-room project. The 1950s through 1970s housing stock was built tight and dated, and the alluvial-fan terrain means foundation and drainage issues surface after the winter rains, right when homeowners are already thinking about upgrades. What starts as a kitchen or bathroom update often grows to include water mitigation, a retaining-wall repair, or bringing an old informal addition up to code. That’s the job we’re built for: one contractor coordinating every phase, from countertops to rooflines to ADUs, with the county permit path handled from the start. This is the full-scope work we do under our Home Renovation service, and the pricing below reflects what Alum Rock homeowners actually face.
Home Renovation Contractors
Signs you need it
Multiple rooms are dated, the layout fights how your family actually lives, and you’re tired of juggling three different trade calls for what should be one project.
What it costs in Alum Rock
A whole-home renovation in Alum Rock typically runs $45,000 to $130,000 depending on square footage, structural work, and whether unpermitted prior work needs legalization.
How we do it
We start with a site walk to map the scope, pull the county permit file on the parcel, sequence demolition and rough-in work around the trades, then manage finishes and final inspection as one accountable contract.
Home Improvement Contractors
Signs you need it
You have a list of smaller upgrades – vanity swaps, countertop replacement, paver work, a new fence – that never seem worth hiring out separately.
What it costs in Alum Rock
Scoped as individual projects, these Alum Rock improvements range from $800 for a backsplash up to $18,000 for a paver driveway, with most exterior improvements falling between $3,500 and $11,000.
How we do it
We bundle the improvements into one work order, bring the right licensed trade for each phase, and coordinate material delivery so the job doesn’t stall between trades.
What Home Renovation Costs in Alum Rock
| Item | Typical range in Alum Rock |
|---|---|
| Kitchen remodel | $14,000 – $45,000 |
| Bathroom remodel | $9,000 – $28,000 |
| Home addition | $45,000 – $130,000 |
| ADU construction | $90,000 – $220,000 |
How long does a home renovation take in Alum Rock?
Plan on 8 to 16 weeks for a single major room and 4 to 8 months for whole-home or addition work. County permit review on unincorporated parcels can add 2 to 6 weeks before work starts, and winter rain can pause exterior phases. Call (866) 472-1908 for a schedule tied to your specific scope.
Will a renovation in Alum Rock require a permit?
Almost always, yes. Alum Rock parcels fall under Santa Clara County permitting, and the county looks carefully at older properties with informal additions. We handle the permit file, the drawings, and the inspections as part of the contract, so legalization work gets folded in rather than becoming a surprise. Call (866) 472-1908 to talk through your parcel.

What pushes a number toward the top of these Alum Rock ranges? Older parcels where a foundation or drainage repair has to happen before the cosmetic work, unpermitted prior additions that need legalization drawings, and hillside retaining-wall work that runs into engineered-solution territory. What doesn’t happen is a surprise change order: we write fixed line-item quotes before work starts, and we don’t revise them mid-job.

FAQs About Remodeling Company in Alum Rock
We can usually begin site work within 1 to 2 weeks of a signed contract, depending on the scope and whether county permit review is already moving. Larger projects that need drawings and permit approval start when the county clears the file, which we track and push. Call (866) 472-1908 for a current start window on your project.
Yes. Alum Rock is unincorporated county land, so we file with Santa Clara County, not the city of San Jose. We prepare the drawings, submit the package, respond to plan-check comments, and pull the final permits, so you’re not left reading a county website at midnight. Call (866) 472-1908 with your parcel number and we can tell you which review path applies.
That’s the entire model. We act as the single general contractor across all phases – interior, exterior, hardscaping, and ADU or prefab installation – so you get one schedule, one contract, and one point of contact. We coordinate the licensed trades; we don’t ask you to sequence the electrician around the roofer. Call (866) 472-1908 to map your project with us.

What Alum Rock Customers Say
"He was upfront about a soil issue that added cost early rather than absorbing it and surprising us at the end."
— Nathan Barrett"Excellent build. Costs came in about six percent over the original contract, driven mostly by material price movement during the build, which he documented each time."
— Todd Sutton"Every inspection passed first time. The building department clearly knows him and that made the whole process easier."
— Daniela Salazar
