C.
An applicant's electronic signature shall be accepted on all forms, applications, and other documents in lieu of a wet signature. For purposes of this chapter, the city will accept as an electronic signature an electronic copy, such as a facsimile image or an electronic image, of an applicant's written signature.
D.
The city's building and safety inspection division in coordination with city's electric utility and fire department is authorized and directed to develop and adopt a standard plan and checklist, of all requirements with which small residential rooftop solar energy systems shall comply to be eligible for expedited review.
E.
The small residential rooftop solar system permit process, standard plan(s), and checklist(s) shall from time to time be revised to substantially conform to recommendations for expedited permitting, including the checklist and standard plans contained in the most current version of the California Solar Permitting Guidebook adopted by the Governor's Office of Planning and Research.

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.
C.
If a use permit is required, a building official may deny an application for the use permit if the official makes written findings based upon substantive evidence in the record that the proposed installation would have a specific, adverse impact upon public health or safety and there is no feasible method to satisfactorily mitigate or avoid, as defined, the adverse impact. Such findings shall include the basis for the rejection of the potential feasible alternative for preventing the adverse impact. Such decisions may be appealed to the city planning commission.
D.
Any condition imposed on an application shall be designed to mitigate the specific, adverse impact upon health and safety at the lowest possible cost.
E.
"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 defining restrictions that do not significantly increase the cost of the system or decrease its efficiency or specified performance.
F.
City shall not condition approval of an application on the approval of an association, as defined in Section 4080 of the Civil Code.
