The Difference Is in the Details
Building in Mountain View means working with a contractor who understands the local market, the local permits, and the local expectations for finish quality. Here is what sets San Jose ADU & Room Addition apart.
Local Permit Expertise
We know Mountain View's building department, plan-check workflow, and zoning quirks. Permits move faster because we submit complete, code-correct drawings the first time.
One Accountable Team
No subcontractor finger-pointing. Project managers, carpenters, plumbers, and electricians, all coordinated by us. One point of contact from kickoff to final walkthrough.
Fixed Quotes, No Surprises
You get a detailed, line-item proposal before signing anything. Change orders only happen when you request them, and they are priced transparently in writing.
Premium Finish Quality
Tight reveals, clean tile work, plumb walls, even paint. The finish work is what Mountain View homeowners notice, and what makes a remodel hold up for the next 20 years.
Clean Job Sites
Floor protection, daily cleanup, dust containment, and a locked, organized site every evening. Many of our Mountain View clients continue to live in their homes during construction.
Real Warranty Backing
Our workmanship warranty is written, transferable on resale, and we stand behind it. If something needs attention after we finish, we come back.
What Mountain View Homeowners Say About Us
Real reviews from real Mountain View clients, neighbors of yours who have lived through the project and would do it with us again.
"Our 1940s home a few blocks off Castro Street needed everything: new foundation work in spots, full kitchen, two baths, and new windows. The team coordinated every trade themselves. We could walk to dinner during construction and come back to a clean, locked site every evening."
"We bought a mid-century post-and-beam home in Monta Loma and were terrified of ruining it with a remodel. The team understands these houses. They kept the exposed beam ceiling, replaced the radiant slab where it was failing, added insulation properly, and our home now feels modern but still authentically mid-century."
"Built a 720 sq ft detached ADU in our Cuesta Park backyard. They handled the Mountain View permits, utility meter, and sewer connection. All of it. Our adult daughter moved in three weeks after final inspection. The finish quality is just excellent."
