5-5K-6: - PERMIT REVIEW REQUIREMENTS.

A. The following procedures apply to applications for small residential rooftop solar energy systems:

  1. The Building Official shall deem complete an application that satisfies the information requirements in the standard plan(s) and checklist(s).

  2. If the Building Official deems the application incomplete, the Building Official shall issue a written correction notice to the applicant detailing all deficiencies in the application and any additional information or documentation required so the application may be eligible for expedited permit issuance.

  3. The Building Official shall issue a building permit, the issuance of which is nondiscretionary, on the same day for over the counter applications or within one to three business days for electronic applications or in either case as soon thereafter as may be practicable upon receipt of a complete application that meets the requirements of the approved checklist and standard plan.

B. The following procedures apply to applications for solar energy systems other than small residential solar energy systems:

  1. The Building Official shall administratively approve applications to install solar energy systems through the issuance of a building permit or a similar nondiscretionary permit. Review of the application shall be limited to the Building Official's review of whether the application meets local, state and federal health and safety requirements.

  2. The Building Official may require an applicant to apply for a conditional use permit if the Building Official finds, based on substantial evidence, that the solar energy system could have a specific, adverse impact upon the public health and safety.

  3. If a conditional use permit is required, the Building Official may deny such application if it makes written findings based upon substantial evidence in the record that the proposed installation of a solar energy system 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. A "feasible method to satisfactorily mitigate or avoid the specific, adverse impact" includes, but is not limited to, any cost-effective method, condition, or mitigation imposed by the City on another similarly situated application in a prior successful application for a permit. The City shall use its best efforts to ensure that the selected method, condition, or mitigation meets the conditions of subparagraphs (A) and (B) of paragraph (1) of subdivision (d) of Section 714 of the Civil Code, as the same may be amended from time to time.

  4. Any conditions imposed on an application to install a solar energy system shall be designed to mitigate the specific, adverse impact upon the public health and safety at the lowest cost possible.

  5. The decision of the Building Official may be appealed to the Planning Agency.
