Contra Costa County Department of Conservation and Development is excited to provide solar contractors the option to use SolarAPP+ to obtain solar building permits faster for qualified projects.
SolarAPP+ is a software program designed to provide a code-compliance check for the majority of residential, roof-mounted, retrofit photovoltaic systems. An overview of guidelines for the program are provided on the County's SolarAPP+ website.
To use SolarAPP+, projects must meet the eligibility requirements and be located within the County's service area. The County's service area for building permits include the unincorporated areas of Contra Costa County, plus the cities of Clayton, Hercules, Lafayette, Moraga, and Orinda.
