Adding a Rooftop Solar Energy System


  • The City of Irvine offers two rooftop solar system options:

    • Same-Day Permits: PermitsDIRECT! powered by Symbium is a web-based platform that makes it possible to get permits for residential solar and battery storage systems the same day. Permits can be paid online and are issued automatically, without manual review or an in-person visit. To qualify for same-day permits, the application must be:

      • For a rooftop solar system no larger than 38.4 kilowatts.

      • For no more than one battery storage system.

      • Submitted by a licensed contractor.

  • Standard: Solar systems that are larger than 38.4 kilowatts and permit applications for more than one battery storage system do not qualify for same-day permit processing; please follow the application steps below.  

For All Other Residential Solar Applications

Your Homeowners Association may have its own approval process. Review your HOA policies and procedures before proceeding with your plans
