Frequently Asked Questions -- Campbell, CA
Common questions about ADU construction in Campbell, CA
Can a small Campbell lot still fit a detached ADU?
It depends on setbacks and lot coverage, but many of Campbell's smaller lots are better suited to a garage conversion or JADU. We run the numbers on your specific parcel during a free feasibility review.
Why are garage conversions so common in Campbell?
Campbell's infill lots are often tighter than Los Gatos or Saratoga parcels, so reusing an existing garage footprint avoids the setback and lot-coverage constraints that limit new detached construction.
How much does a Campbell ADU cost?
Garage conversions in Campbell typically run $140,000-$220,000, while detached units (where lot size allows) run $250,000-$420,000+. We confirm which path fits your lot during a free consultation.
Do you handle Campbell's permit process?
Yes -- we prepare and submit the full application to the City of Campbell, respond to plan-check comments, and schedule every inspection through final sign-off.
