Summary
Hawthorne requires solar panel applications to be filed in person with the building department because the city cannot process electronic submittals, and it caps permit fees under state Government Code limits.
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. ... 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.
Full Breakdown
R. Section 22003. The building department must adopt a standard plan and checklist covering everything a small residential rooftop system needs to qualify for expedited review, and that checklist and permit process must "substantially conform" to the recommendations in the current California Solar Permitting Guidebook published by the Governor's Office of Planning and Research. 55, Government Code Sections 66015 and 66016, and Health and Safety Code Section 17951, meaning the city cannot charge more than its reasonable cost of processing the permit. 050 requires every solar energy system to meet state and local health and safety standards, with water-heating systems certified under the California Plumbing and Mechanical Code and electricity-producing systems meeting California Electrical Code and IEEE standards along with applicable Public Utilities Commission safety and reliability rules.
Violations & Fines
The chapter does not set its own fine schedule for panel-permit violations; general Title 15 enforcement applies, including the withholding of permits and certificates of occupancy under § 15.75.010 where inspections reveal noncompliant work.
