ADU and home addition project in San Jose

Adding space is one of the smartest investments a San Jose homeowner can make — whether it's a backyard ADU for rental income or family, a garage conversion, or a room addition that finally gives you the space you've outgrown. We design and build accessory dwelling units and home additions across San Jose and the South Bay, handling the whole project from first sketch to final inspection.

We're a family-owned contractor with more than 12 years in the South Bay, and we treat every project like it's our own home. With an ADU or addition you're not just remodeling a room — you're adding square footage, structure, and systems to your property, so the team you choose really matters. You work directly with the owners and one experienced crew, which means clearer communication and fewer of the surprises that derail bigger builds.

Because we manage design, permitting, and every trade in-house, the whole project runs on one schedule. Foundation, framing, plumbing, electrical, and finishes are sequenced to work together, and we handle the City of San Jose permitting and inspections so everything is done by the book.

San Jose has some of the most ADU-friendly rules in the state, but they come with details that affect your budget and timeline — impact fees, size thresholds, setbacks, and utility connections. We help you make the most of them: staying under the size limits that avoid impact fees when it makes sense, choosing between a detached ADU, a garage conversion, or a JADU, and planning a layout that lives well for renters or family.

We build the full range: detached backyard ADUs, garage and basement conversions, junior ADUs (JADUs), and room additions and second-story additions that expand your existing home. Whatever the scope, you get the same family-owned care, the same single accountable team, and a finished space that looks like it was always part of the property.
