ADUs & home additions in San Jose

San Jose lots hold more than most people think. A detached ADU in the backyard can carry rental income or keep family close. A garage conversion turns dead storage into a real living unit. A room addition gives you the space you've outgrown without leaving the neighborhood you love. We design and build all of it across San Jose and the South Bay, and we carry the whole project from first sketch to final inspection.

An ADU or addition isn't redecorating. You're adding square footage, structure, and systems to your property, so the team you choose really matters. We're a family-owned contractor that has built in the South Bay since 2012, and we treat every project like it's our own home. You work directly with the owners and one experienced crew, which means clearer answers, fewer hand-offs, and fewer of the surprises that derail bigger builds.

Because design, permitting, and every trade stay in-house, the whole project runs on one schedule. Foundation, framing, plumbing, electrical, and finishes are sequenced by the same people who planned them, and we handle the City of San Jose permitting and inspections ourselves, so everything is done by the book.

San Jose has some of the most ADU-friendly rules in the state, but the fine print decides your budget and timeline: impact fees, size thresholds, setbacks, and utility connections. We know where the lines are. Sometimes the smart move is keeping a unit under the size limit that avoids impact fees. Sometimes it's a garage conversion or a JADU instead of a detached build. We'll lay out the options and plan a layout that lives well for renters or for family.

The full range is on the table: detached backyard ADUs, garage and basement conversions, junior ADUs (JADUs), and room and second-story additions that grow the house you already have. Whatever the scope, it's the same family, the same accountable crew, and a finished space that looks like it was always part of the property.
