San Jose sets its own limits for detached ADUs on single-family lots, and these four decide what fits in your backyard.

One team handles the entire process under one roof, so you don't have to coordinate a separate architect, permit expediter, and contractor yourself.
These four Apex Homes plans have already passed City of San José review. Pick one, and your permit only has to clear your lot.

APEX HOMES USA, INC has 4 plans on the City’s pre-approved ADU list: the 746, 749, 797, and 991 sq ft designs.
The City reviews your lot either way. With a pre-approved plan, the building is already approved, so there is less to design, submit, and wait for.

Before, any change to a pre-approved plan could send it back for a regular permit review. Apex Homes come with San Jose’s ONLY option list: the upgrades clients ask for most, with no new review.
More natural light, better airflow, and an easy step out to the yard, so the ADU feels bigger than its footprint.
Daylight from above when a two-story main house or a nearby wall shades the ADU's windows.
A practical answer for sloped or uneven lots, drainage and moisture concerns, less stable soil, or tricky utility access.
From initial design to final move-in, we handle every detail of your ADU journey with expertise and care.
Apex Homes reviews your lot's zoning, setbacks, and utility hookups, then delivers a tailored recommendation within 48 hours, at no cost.
In 1–2 weeks, our design team builds your custom floor plan with 3D renderings, material selections, and structural engineering.
Apex Homes handles your permit applications and city plan checks, with a 98% approval success rate.
Site prep through final trim, with premium materials and craftsmanship, typically 4–6 months.
A full inspection and punch list review before you get the keys, usually within 1–2 weeks.
One team, all-in-one: design, permits, and construction, without you having to coordinate a separate architect, expediter, or contractor.
Book a Free ConsultationMoving is expensive, stressful, and disruptive. A new mortgage at today's rates. A bidding war you might not win. A new neighborhood to learn, new schools, new everything. And even after all that, there's no guarantee the next house actually fits your family any better than this one does.
Add the room your family needs without a new mortgage, a new school district, or goodbye to the neighbors you know. It's built right where you already live.
Skip the bidding wars and move-in surprises. You get a fixed price and a known outcome, on the property you already know.
Give parents getting older or kids moving back their own front door and their own space, close enough to see every day.
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 ADU could be earning you right now, driven by strong rental demand across San Jose.
The typical resale-value increase a legal, permitted ADU adds to a San Jose home, on top of the rental income it can generate along the way.
Without it, aging parents, adult children, or live-in caregivers are stuck choosing between crowding your home or living elsewhere.
Design-builders, general contractors, and prefab vendors each cover part of the job. Apex Homes covers all of it, in-house.

"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."
