One team handles the entire process under one roof, so you don't have to coordinate a separate architect, permit expediter, and contractor with the City of Los Altos yourself.
Los Altos is one of the most affluent, lowest-turnover cities on the Peninsula, with top-ranked schools and large, well-established lots. Homeowners here are rarely building an ADU to chase rent, it's almost always about family: aging parents, a returning adult child, or space for long-term caregiving without giving up the house.
No new mortgage, no new school district, no goodbye to the Los Altos neighbors you know. Just more space, right where you are.
No bidding wars, no move-in surprises, no guessing what a new house actually needs. Just a fixed price, on the Los Altos property you already know.
Parents, grown kids, or whoever needs it get their own front door and their own space, close enough to see every day, on a lot with real room to spare.
We manage every step of design, permitting, and construction, so you don't have to navigate the City of Los Altos' process on your own.

"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."
