(Ord. 2094 § 2, 2015)
§ 15.70.030. Purpose.¶
The purpose of the chapter is to adopt an expedited, streamlined solar energy permitting process that complies with the Solar Rights Act and AB 2188 (Chapter 521, Statutes 2014) 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 city of Hawthorne, and expanding the ability of property owners to install solar energy systems. The chapter allows the city of Hawthorne to achieve these goals while protecting the public health and safety.
(Ord. 2094 § 2, 2015)
§ 15.70.040. Applicability.¶
A. This chapter applies to the permitting of all small residential rooftop solar energy systems in the city of Hawthorne.
B. Small residential rooftop solar energy systems legally established or permitted prior to the effective date of the ordinance codified in this chapter are not subject to the requirements of this chapter unless physical modifications or alterations are undertaken that materially change the size, type, or components of a small rooftop energy system in such a way as to require new permitting. Routine operation and maintenance or like-kind replacements shall not require a permit.
(Ord. 2094 § 2, 2015)
§ 15.70.050. Solar energy system requirements.¶
A. All solar energy systems shall meet applicable health and safety standards and requirements imposed by the state and the city of Hawthorne, local fire department or district.
B. Solar energy systems for heating water in single-family residences and for heating water in commercial or swimming pool applications shall be certified by an accredited listing agency as defined by the California Plumbing and Mechanical Code.
C. Solar energy systems for producing electricity shall meet all applicable safety and performance standards established by the California Electrical Code, the Institute of Electrical and Electronics Engineers, and accredited testing laboratories such as Underwriters Laboratories and, where applicable, rules of the Public Utilities Commission regarding safety and reliability.
(Ord. 2094 § 2, 2015)
§ 15.70.060. Duties of the building department.¶
A. All documents required for the submission of an expedited solar energy system application shall be made available on the publicly accessible city of Hawthorne website.
B. All documents must be submitted in person at the city of Hawthorne building department. The building department shall issue a building permit or use permit, within one to three days, for over-the-counter applications if it meets the requirements of the approved checklist and standard plan. The city of Hawthorne does not have infrastructure capable to review electronically submitted documents for small residential rooftop solar energy systems, therefore, applications and other documents will not be submitted electronically.
C. An applicant's electronic signature is not accepted on all forms, applications, and other documents in lieu of a wet signature. The city is unable to comply with the requirement set forth in Government Code Section 65850.5(g)(1) stating that the city "shall authorize the electronic signature on all forms, applications, and other documentation in lieu of a wet signature by an applicant." The city does not have a system in place that is capable of verifying an electronic signature as required by Government Code Section 16.5. Moreover, the California Secretary of State procedures allow the use of electronic signatures only if they could be verified using Public Key Cryptology (PKI) or Signature Dynamics technologies. (2 C.C.R. Section 22003.) Unfortunately these technologies add complexity and expense to the requirement promulgated by Section 65850.5(g)(1) and the city is not in a financial position nor does it have the infrastructure to deploy such technology. Accordingly, based on the reasons set forth herein, the city has determined that it is unable to authorize the acceptance of an electronic signature on all forms, applications, and other documents in lieu of a wet signature by an applicant for a residential rooftop solar energy system.
D. The city of Hawthorne building department shall 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 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.
F. All fees prescribed for the permitting of small residential rooftop solar energy systems must comply with Government Code Section 65850.55, Government Code Section 66015, Government Code Section 66016, and State Health and Safety Code Section 17951.
(Ord. 2094 § 2, 2015)
§ 15.70.070. Permit review and inspection requirements.¶
A. The city of Hawthorne building department shall adopt an administrative, nondiscretionary review process to expedite approval of small residential rooftop solar energy systems within thirty days of the adoption of the ordinance codified in this chapter. 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 city of Hawthorne 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. The city of Hawthorne planning department shall review all plans upon a hold of a complete application. Approval by the planning department of said plans are requisite for a plan check by the city of Hawthorne building department.
D. 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 of Hawthorne planning commission.
E. Any condition imposed on an application shall be designed to mitigate the specific, adverse impact upon health and safety at the lowest possible cost.
F. 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 of Hawthorne on another similarly situated application in a prior successful application for a permit. The city of Hawthorne 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.
G. The city of Hawthorne shall not condition approval of an application on the approval of an association, as defined in Section 4080 of the Civil Code.
H. 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.
I. Only one inspection shall be required and performed by the building 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.
J. 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.
K. 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.
