General Contractor in Cupertino, CA

Kitchen and bathroom remodels, additions, ADUs and garage conversions for Cupertino homes.

Remodeling and Construction in Cupertino

Cupertino homeowners tend to stay put. Between the schools and what it now costs to move within Silicon Valley, remodelling the house you own is usually the better maths than buying a different one — and that shows up in the kind of work we get asked for here: thorough, permanent, done once.

Much of Cupertino's housing stock dates from the fifties through the seventies, on flat lots with generous frontage. The bones are good. What they typically need is a kitchen that opens to living space, bathrooms that use their footprint properly, and the systems behind the walls brought up to date.

D One Builders is a licensed general contractor (CSLB #1028049) working across the South Bay. We handle kitchen remodels, bathroom renovations, home additions, ADUs, garage conversions and custom homes for Cupertino property owners.

Kitchen remodels

The most common Cupertino project by some distance. Cupertino kitchens are frequently a closed room with a doorway, and the value is in removing what separates it from everything else — which is a structural question before it is a design one.

Bathroom renovations

Primary suites and hall baths that have never been touched since the house was built. There is usually more room to gain than the existing layout suggests.

Additions, ADUs and garage conversions

Flat lots and deep frontages make Cupertino well suited to both additions and second units. A garage conversion is often the fastest and cheapest route to a legal second unit.

Why Cupertino Owners Work With Us

We price the whole job. Including what an older house is hiding. An estimate that ignores it is not a lower price, it is a deferred one.

You always know where the job stands. A real schedule, regular updates, and a direct line to the people actually building it.

We are close by. Cupertino sits inside our regular service area alongside San Jose and Los Gatos.

Cupertino questions

How much does a kitchen remodel cost in Cupertino?

Kitchen remodels in Cupertino generally start around $70,000 for a well-executed refresh and pass $150,000 for a full gut with layout changes, custom cabinetry and stone surfaces. The variable that moves the number most is what is behind the walls — older homes here often need electrical and plumbing work that a finish-only estimate ignores.

Do you build ADUs in Cupertino?

Yes. We build detached ADUs, attached units and garage conversions throughout Cupertino. California requires cities to review compliant ADU applications ministerially, which makes them more predictable to permit than a typical remodel.

How long does a Cupertino remodel take?

A kitchen or bathroom typically runs three to five months from demolition to final, with design and permitting before that. Additions and ADUs run six to twelve months end to end. We give you a real schedule at the start and tell you when it moves.

Are you licensed and insured?

Yes — CSLB #1028049, licensed and insured, and we handle permitting and inspections directly with the city rather than leaving it to you.
