Saratoga ADU Guide
California's ADU laws make it easier than ever to add a unit in Saratoga. Here's what every homeowner should know before building.
By-Right Approval
California's statewide ADU law makes compliant ADUs ministerial — no public hearing, no neighbor veto, and a mandatory 60-day decision. We design specifically to qualify for this by-right path in Saratoga.
What Your Lot Allows
Detached ADUs are allowed up to 1,200 sq ft, junior ADUs up to 500 sq ft, and cities must permit at least 800 sq ft with only 4-foot side and rear setbacks. Most Saratoga lots qualify — we confirm during feasibility.
Parking & Utilities
If your property is near transit or you're converting a garage, added parking is waived. New detached ADUs can have their own utility meters, address, and lease — we handle the connections and metering.
ROI in the West Valley
ADUs add significant property value and strong rental income across Santa Clara County. A backyard unit or converted garage can offset your mortgage while giving family a private, independent place to live.
Frequently Asked Questions
Got questions about building an ADU in Saratoga? We've got answers.
Yes. Every ADU requires a building permit, but California's statewide ADU law makes approval ministerial (by-right) for compliant projects — no public hearing and a 60-day decision. We prepare the full permit set and manage the City of Saratoga / Santa Clara County submittal for you.
