Han’s Builder Construction is a family-run building company working across San Jose and the Bay Area. For more than twenty years we have handled rebuilds, additions and remodels — from the first shovel of dirt to the last piece of trim.
We keep the company small on purpose. That means the person who walks your project and gives you a price is the same person standing on your job every morning.
We visit the site, listen to what you want, and talk through what is realistic — with a straight answer on cost and schedule.
Drawings, engineering and city permits handled for you, so the job starts legally and never gets shut down mid-way.
One crew, one point of contact. Daily clean-up, clear progress updates and a schedule we actually keep.
We walk the finished job with you, fix anything on the punch list, and hand over a home we are proud to put our name on.
Most of our work comes from repeat clients and referrals — that only happens when people trust you.
Owner-operated since day one. Allen is on the job, not just at the estimate.
Fully licensed California contractor with general liability and workers-comp coverage.
Written, itemised estimates. Change orders only in writing, only with your approval.
