15.04.010 - Title.

This chapter shall be known and may be referred to as the "Modoc County Roof-Top Solar Provisions."

(Ord. No. 352, 11-24-2015)

Exceptions & meaning →

15.04.020 - Purpose.

The purpose of the chapter is to adopt an expedited, streamlined solar permitting process that complies with the Solar Rights Act and Section 65850.5 of the California Government Code to achieve timely and cost-effective installations of small residential rooftop solar energy systems. The chapter encourages the use of solar systems by removing unreasonable barriers, minimizing costs to property owners and the county, and expanding the ability of property owners to install solar energy systems. The chapter allows the county to achieve these goals while protecting the public health and safety.

H. "Restrictions that do not significantly increase the cost of the system or decrease its efficiency or specified performance" means:

  1. For water heater systems or solar swimming pool heating systems: an amount exceeding ten percent of the cost of the system, but in no case more than one thousand dollars, or decreasing the efficiency of the solar energy system by an amount exceeding ten percent, as originally specified and proposed.

15.04.070 - Permit review and inspection requirements.

A. The county building and safety department shall adopt an administrative, nondiscretionary review process to expedite approval of small residential rooftop solar energy systems within 30 days of the adoption of this chapter. The building and safety department shall issue a building permit or other nondiscretionary permit [the same day for over-the-counter applications or within one to three business days for electronic applications, of receipt of a complete application and meets the requirements of the approved checklist and standard plan. A building official may require an applicant to apply for a use permit if the official finds, based on substantial evidence, that the solar energy system could have a specific, adverse impact upon the public health and safety. Such decisions may be appealed to the county planning commission.

B. 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 of 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 county board of supervisors.

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 county on another similarly situated application in a prior successful application for a permit. The county 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. The county shall not condition approval of an application on the approval of an association, as defined in Section 4080 of the Civil Code.

G. If an application is deemed incomplete, a written correction notice detailing all deficiencies in the application and any additional information or documentation required to be eligible for expedited permit issuance shall be sent to the applicant for resubmission.

H. Only one inspection shall be required and performed by the building and safety department for small residential rooftop solar energy systems eligible for expedited review. A separate fire inspection may be performed if an agreement with the local fire authority does not exist to perform safety inspections on behalf of the fire authority.

I. The inspection shall be done in a timely manner and should include consolidated inspections. An inspection will be scheduled within two business days of a request and provide a two-hour inspection window.

J. If a small residential rooftop solar energy system fails inspection, a subsequent inspection is authorized but need not conform to the requirements of this chapter.
