San Jose, CA General Contractor & Remodeler

Santa Clara ADU Builders is a design-build general contractor and remodeler working across East and North San Jose. We plan, permit, and build home additions, finished basements, whole-home renovations, and kitchen and bath remodels with one accountable crew, so the team that prices your project is the same team that frames it, runs the systems, and hands it back finished.

A remodel or an addition is one of the bigger decisions a San Jose homeowner makes, and most of what decides how it turns out is settled long before any finish goes on. The layout, the structure behind the walls, the grade the house sits on, the permit set, the wiring, and the plumbing all get worked out before the cabinetry and the surfaces you actually see. That is the reason Santa Clara ADU Builders runs as a design-build company first. We plan the work carefully around the home you have and the budget you set, build every phase to current code, and finish it so the space holds up as well years from now as it does the week you move back in.

We focus on the east and north sides of San Jose, where the Evergreen and Berryessa flats, the Alum Rock corridor, and the homes climbing into the East Foothills give us a real range of lots to work with. Larger parcels leave room to build out where a household needs the space, and hillside lots reward planning the access and the structure from the very first sketch instead of discovering them halfway through. A contractor who knows how those conditions change a project scopes around them up front, which keeps the budget honest and the schedule moving.

Whether you want to push out the back of the house for a bigger kitchen and family room, finish a daylight basement under a sloped lot into real living space, add the bedrooms a growing household has outgrown, or take a dated floor plan down to the studs and rework the whole thing, the process opens the same way. We start with an honest planning conversation, write a real scope, and put the price in front of you before any work begins. Most of our projects come from one neighbor pointing us toward the next, which is exactly the way we set out to build the company.

About Santa Clara ADU Builders

Santa Clara ADU Builders is a San Jose design-build general contractor and remodeler serving homeowners on the east and north sides of the city. We plan, draw, permit, and build home additions, basement finishing, whole-home renovations, kitchen and bath remodels, and the custom carpentry that ties a project together, all with the same in-house crew. From the first walk of the property to the final inspection, one accountable team owns the project, so there is never a designer, a framer, and a finisher pointing at one another when the plan meets the real house.

We built the company around the parts of a project a homeowner cannot easily see. The framing and the connections, the wiring and the plumbing, the drainage and the structure on a graded lot all quietly decide how the work performs over the years. Anyone can make a finished room photograph well on the day it wraps. Making one that still feels solid and still works a decade later comes down to the work behind the drywall, and that is the work we refuse to shortcut.

Most of our jobs come from referrals, which is the business we wanted from the start. We are licensed and insured, we draw the plans and pull the permits, and we put the scope and the number in writing before the contract. When you call 350-220-7959, you reach the crew that actually plans and builds the project, not a salesperson and not a lead broker handing your job to whoever bids it lowest.

Why a design-build crew matters on an east San Jose remodel

When one company designs a project and another builds it, the seam between them is where things go wrong. A plan that reads beautifully on paper can run into a load-bearing wall, an undersized electrical panel, or a plumbing route nobody accounted for, and suddenly there is no clear owner of the fix. A design-build crew closes that seam. The same team that walks your home, draws the plan, and quotes the work is the team that frames the walls, runs the systems, and sets the cabinets.

That continuity counts for more on the east and north sides of San Jose, where graded lots, mixed-era homes, and an involved permit process show up regularly. We plan around the real constraints of your specific house from the first sketch, so the scope we hand you is one we already know we can build. It keeps the project from stalling, it keeps the budget from drifting, and it puts a single accountable crew on the result from the first day of demolition through the final sign-off.

It also means the decisions that drive cost and livability get made together rather than in isolation. The layout, the structure, the systems, and the finishes all pull on one another. Planning and building them as one project, instead of bidding each phase to a different trade, is what makes the finished space feel like a real part of the home rather than a set of separately quoted parts.

We build for the year after the final inspection

A home is a structure first, and the structure is what we obsess over. We open the walls to see what is actually there, frame to spec with the connections current code requires, and run the wiring, the plumbing, and the mechanical to standard. Only then do we move on to the drywall, the cabinetry, the trim, and the surfaces you live with every day.

The finishes matter too, and they have to be chosen to last. We use durable cabinetry, quality flooring, solid trim, and fixtures suited to how the space will really be used, whether that is a busy family kitchen, a finished lower level, or a new primary suite in an addition. We pick them alongside you to fit the design and the budget, never as a default upsell tacked onto the bid.

We build to current local building and energy code, with the inspections that make a home both safe and durable. The aim is simple. A space that looks as good and works as well years out as it did the day the crew packed up and the project wrapped.

Our San Jose crew handles the whole project: a general contractor to manage the trades and the permits, home additions to add the room you need, home renovation to transform a home you already love, remodeling your kitchen for the rooms you use most, custom carpentry for the built-ins and trim you see every day, and a finished basement to turn empty space below into real living space.

Beyond San Jose itself, we cover the surrounding area, including our Milpitas crew, project work in Fremont, Alum Rock general contractor, our Berryessa crew. If you searched for a general contractor near San Jose, you are in the right place, a local crew who answers.

What San Jose Homeowners Ask Us

How much does a home remodel cost in San Jose?

There is no flat rate, because no two homes or projects match. The price tracks the scope, whether it is one room or the whole house, the condition behind the walls, the finishes you choose, and how much the layout changes. On a graded or hillside lot, the structural and drainage work can move the number too. We give you an itemized, written estimate after a real in-home consultation, with the price spelled out before any work starts. Call 350-220-7959 for a free consultation and an honest figure.

Do you work on hillside and sloped lots in the East Foothills?

Yes. A graded lot changes the access, the foundation, and often the structure, which is exactly why we plan for it from the first sketch rather than discovering it mid-project. We assess the slope, the soil, the drainage, and how a crew and materials will reach the work, then scope and engineer the project around those realities. A sloped lot also frequently opens up a daylight lower level that can become real living space.

Will you handle the full plan set and the permitting?

Yes. We draw the plans, coordinate any structural and energy calculations the work requires, submit the permit set, and manage the city inspections from start to finish. Permitting in San Jose is involved, and handling all of it is part of the job, not an extra you have to chase yourself while the project sits.

Do you take on whole-home renovations as well as single rooms?

Both. We handle single-room remodels, home additions, basement finishing, custom carpentry, and full whole-home renovations, all with the same licensed design-build crew. Whether you want one room reworked or the entire house brought up to date at once, a single accountable team owns it. Call 350-220-7959 to talk through your project.
