Sunnyvale sits between two of the Valley's largest employers, and rents here run among the highest in Santa Clara County. Lots tend to run smaller than in neighboring cities, so getting the floor plan right matters more here than almost anywhere else Apex builds.
No new mortgage, no new school district, no goodbye to the Sunnyvale 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 Sunnyvale 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.
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 Sunnyvale yourself.
We manage every step of design, permitting, and construction, so you don't have to navigate the City of Sunnyvale's process on your own.

Book a Free ConsultationUp to 1,000 sq ft, plus a Junior ADU up to 500 sq ft. Side and rear setbacks run 4 ft minimum; height caps at 16 ft, or 18 ft within a half-mile of a transit stop. Your free feasibility study confirms the exact numbers for your lot.
Existing multi-family properties may add up to eight detached ADUs, never exceeding existing unit count; new multi-family construction is capped at two detached ADUs.
Every year that yard sits unused in Sunnyvale is rent, equity, and space someone in your family could actually be using.
Left on the table. That's a realistic range for a well-built two-bedroom ADU in Sunnyvale, one of the tightest rental markets in the county.
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 Sunnyvale home.
Without it, aging parents, adult kids, or long-term guests are stuck choosing between crowding your home or leaving Sunnyvale 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, with compact layouts built for Sunnyvale's smaller lots.
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."

A look at completed Apex Homes ADU builds across the Bay Area.
service includes:
A 991 sq ft 3-bed / 2-bath detached ADU in San Jose, fully condo-converted under AB 1033 and ready for separate sale — either the main house or the ADU can be acquired, financed, and resold on its own.
service includes:
Set on a corner lot in San Jose, this 983 sqft, two-story ADU is positioned at the rear of the property. It's a placement that lets a growing family live together today, and converts just as easily to a rental down the road.
service includes:
A 749 sq ft, 2-bed / 2-bath detached ADU in San Jose, built turnkey alongside a full remodel and ADU-title-conversion of the existing main house. The owner ends up with two independent rental units on a single 7,800 sq ft lot.
service includes:
A 1,200 sq ft, 3-bed / 2-bath detached ADU added to a duplex lot in central San Jose — taking the property from two income units to three, with the new ADU placed at the rear of a deep narrow lot and four mature trees preserved through construction.
Design-builders, general contractors, and prefab vendors each cover part of the job. Apex Homes covers all of it, in-house.
