Saratoga ADU Requirements and Permit Rules

These four City of Saratoga rules shape the size, height, placement, and parking of a detached ADU on a single-family lot.

Detached ADU, Single-Family Lot · Source: City of Saratoga

Maximum Size
1,000–1,200 sq ft
1,200 sq ft when the ADU sits outside the side and rear setbacks, and 1,000 sq ft when it uses the 4 ft setbacks.
Side and Rear Setbacks
4 ft
No less than 4 ft at the side and rear. The front setback of your zoning district still applies.
Height
16 ft
16 ft, or 18 ft within a half mile of major transit. Add 2 ft to match the main home's roof pitch.
Parking
1 space
One off-street space, waived within a half mile of public transit or when the ADU is built along with a new home.

Why Saratoga homeowners build with Apex Homes
SMARTER THAN MOVING

You Don't Need a New Home. You Need a Second One.

Saratoga's hillside lots and top-rated schools have kept it one of the most stable, low-turnover housing markets in the county. Families tend to stay for decades, so the case for a second unit here is usually about keeping family close, not chasing rent.

Same Address, More Space

No new mortgage, no new school district, no goodbye to the Saratoga neighbors you know. Just more space, right where you are.

Certainty You Won't Get From a Move

No bidding wars, no move-in surprises, no guessing what a new house actually needs. Just a fixed price, on the Saratoga property you already know.

A Home of Their Own, Steps From Yours

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.

What Your Backyard Is Costing You

Every year that yard sits unused in Saratoga is space your own family could be using, not just rent left on the table.

$3,200–$4,300/mo

What a well-built two-bedroom ADU could realistically earn as a rental, if that's the route you take, in one of the county's most affluent rental submarkets.

Six figures

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 Saratoga home.

Multigenerational

Without it, aging parents, adult kids, or long-term guests are stuck choosing between crowding your home or leaving the Saratoga school district altogether.

None of that has to stay true. Here's what changes once you build.
