Stanislaus County Building Permit Services and SolarAPP+ provide instant PV Solar Plan review for Residential Rooftop systems and Energy Storage Systems.

Stanislaus County has partnered with SolarAPP+ to provide contractors with a permitting option that allows them to get an expedited plan review for residential roof top solar photovoltaic and energy storage systems. The SolarAPP+ system is an automated web-based design review system that checks to ensure proposed systems comply with current California building, electrical, and fire codes.

What Projects do not qualify for SolarAPP+

How do I use SolarAPP+?

What do I do after my permit is issued?

  • Once the permit is issued you can complete the installation.
  • When the installation is complete and you are ready for inspection you will need to request an inspection by calling (209)525-7550 or use the Citizen Access Portal to schedule your inspection.

What documents do I need for the inspection?

  • Print out a hard copy of the submitted SolarAPP+ Approval Document and it will serve as an inspection checklist.

How do I make changes to approved projects after permit issuance?

  • Projects can be revised as many times as the contractor wishes prior to installation. After revisions are complete and the project is submitted, SolarAPP+ will then run another compliance check. If your updated system design is code compliant, the system will reissue your revised Approval Document and Inspection Checklist.
  • After the revised Approval Document is issued you will be required to use the County’s Citizen Access Portal to resubmit the revised Approval Document.
  • SolarAPP+ does not charge additional fees for the first three revisions (Documents B, C, D), while each subsequent revisions require a $25 project fee to SolarAPP+. If a revision requires payment of an additional fee, the Approval Document is not issued until the fee is paid.
