(b) A city or county shall administratively approve applications to install solar energy systems through the issuance of a building permit or similar nondiscretionary permit. Review of the application to install a solar energy system shall be limited to the building official's review of whether it meets all health and safety requirements of local, state, and federal law. The requirements of local law shall be limited to those standards and regulations necessary to ensure that the solar energy system will not have a specific, adverse impact upon the public health or safety. However, if the building official of the city or county makes a finding, based on substantial evidence, that the solar energy system could have a specific, adverse impact upon the public health and safety, the city or county may require the applicant to apply for a use permit.
(c) A city, county, or city and county may not deny an application for a use permit to install a solar energy system unless it makes written findings based upon substantial evidence in the record that the proposed installation would have a specific, adverse impact upon the public health or safety, and there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact. The findings shall include the basis for the rejection of potential feasible alternatives of preventing the adverse impact.
(g) (1) On or before September 30, 2015, every city, county, or city and county, in consultation with the local fire department or district and the utility director, if the city, county, or city and county operates a utility, shall adopt an ordinance, consistent with the goals and intent of subdivision (a), that creates an expedited, streamlined permitting process for small residential rooftop solar energy systems.
