Building in Sunnyvale
Every city in our area is its own jurisdiction with its own review process. What's true in one does not carry across the city line — which is why this page exists rather than a single generic service-area page.
Sunnyvale's housing stock is heavily mid-century single-story on regular lots, which is close to ideal for a detached ADU — usable rear yard, straightforward access, and utilities that don't have to cross the whole property.
We work throughout Sunnyvale — whether you're in Downtown Sunnyvale, Ortega Park, Cherry Chase, or Birdland, the build is the same standard.
Permits. Work in Sunnyvale is permitted through the City of Sunnyvale Building Division. We carry the submittal and the plan-check corrections — that is our job, not yours.

What a Sunnyvale project costs
We publish our real ranges rather than making you book a call to find them out, and our minimum project size is $20,000. What moves a number in Sunnyvale is rarely the finishes — it is the site, the utilities and what turns up once something is opened.
Public record
Permits and ADU rules in Sunnyvale
These are links to the city's own pages, not our summary of them. We carry the submittal and the plan-check corrections on a project we build, so this is not information you have to act on yourself. It is here because you should be able to check it either way.
Sunnyvale splits ADUs into a streamlined route needing only a building permit and a non-streamlined route that needs a Miscellaneous Plan Permit from Planning first. Which one you land in is worth settling before anyone draws anything.
Pre-approved ADU plans. Sunnyvale publishes a gallery of pre-approved ADU plans that homeowners can build from. Since AB 1332 took effect on January 1, 2025, California cities have had to run a pre-approved ADU plan program and post the approved plans publicly. Where a usable plan exists it can take real time and design cost out of a project, because the design has already been reviewed and only the site-specific work is left.

Links checked August 2026 and pointing at government pages. Cities change both their pages and their rules, so confirm anything current with the City of Sunnyvale Building Division. We deliberately do not publish Sunnyvale permit fees or review times here: those move, they vary by project, and a number that is out of date is worse than no number at all.
