San Jose / Plans & permits

A head start with
preapproved ADU plans.

San Jose’s program lets you start with a building plan the city has already reviewed. You still need documents for your property, utility connections and site conditions.

What does preapproval cover?

Preapproval applies to the building plan. Site placement, setbacks, utility connections and other property-specific requirements still need review. Ask the vendor what is included in its service and who prepares the site submission.

Confirm the current eligibility criteria, accepted plan version and site restrictions with San Jose before relying on an expedited schedule.

  • Can the layout work with your property’s access and utility locations?
  • What design changes would require additional review?
  • Who handles site drawings, engineering and the permit application?
  • Does the price include installation and site work, or only plans?
