The Division of the State Architect (DSA) revised the Interpretation of Regulations (IR) IR 16-8: Solar Photovoltaic and Thermal Systems Review and Approval Requirements.

IR 16-8 has been updated with minor revisions to the structural provisions, and to the Fire and Life Safety requirements in Section 6. The revision in Section 6 clarifies designs for structures with and without uses underneath and clearance criteria for photovoltaic installations not encroaching into dedicated fire lanes.\

Please direct any questions regarding IR 16-8 to George Barnes, Principal Fire and Life Safety Officer at George.Barnes@dgs.ca.gov.
