One team handles the entire process under one roof, so you don't have to coordinate a separate architect, permit expediter, and contractor yourself.
Moving is expensive, stressful, and unnecessary when the space you need already exists on your own lot. With Apex Homes, you can house family, add income, and increase your property's value, all without changing your address.
No new mortgage, no new school district, no goodbye to the neighbors you know. Just more space, right where you are.

Every year that yard sits unused in San Jose is rent, equity, and space someone in your family could actually be using.
Left on the table. That's what a well-built two-bedroom ADU could be earning you right now, driven by steady demand from San Jose's tech employers.
In equity your property isn't capturing yet. A legal, permitted ADU is one of the few upgrades that adds this much value to a San Jose home.
Without it, aging parents, adult kids, or long-term guests are stuck choosing between crowding your home or leaving San Jose altogether.
None of that has to stay true. Here's what changes once you build.
Every floor plan includes architectural drawings, structural engineering, and Title 24 compliance.
Apex Homes builds ADUs across 20+ Silicon Valley and Bay Area cities. Find your city below for local pricing, regulations, and permitting timelines.
"I'm usually stingy with five-star reviews, but Apex Homes absolutely rocks. From the first call, they treated my scattershot sketches like gold: polished the design, wrangled the permits so I never saw City Hall, and kept every penny transparent."
