Solar Permitting for Homes

What is SolarAPP+?
SolarAPP+ (Solar Automated Permit Processing+) is an automated online permitting platform that allows licensed contractors to apply for permits for standard residential rooftop solar and energy storage systems.
State law requires most cities and counties in California to adopt this system to streamline the permitting process for certain types of residential solar projects.
Before applying for an automated solar plan review and solar permit, projects must meet certain requirements.
SolarAPP+ is designed to provide a code-compliance check for the majority of residential, roof-mounted, retrofit photovoltaic systems.
To see which systems are eligible, review the SolarAPP+ eligibility requirements. Only projects that meet these requirements are eligible to use the automated SolarAPP+ portal for instant permitting.
If the system is ineligible, please follow the guidelines in the Submittal Checklist.
Once all submittal items are complete, applications can be submitted through the Online Permit Center.
