Summary
Mission Viejo cannot slow-walk a home solar application: Chapter 8.14 requires the building division to run an expedited, nondiscretionary review track for small rooftop solar systems under 10 kilowatts AC (or 30 kilowatts thermal) on single-family and duplex homes, with electronic submittal, a published checklist, and permit issuance the same day or within three business days.
The purpose of this chapter is to adopt an expedited, streamlined solar 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. This chapter encourages the use of solar systems by removing unreasonable barriers, minimizing costs to property owners and the city, and expanding the ability of property owners to install solar energy systems. This chapter allows the city to achieve these goals while protecting the public health and safety.

Full Breakdown
Sec. 020 states the chapter's purpose: adopt an expedited, streamlined solar permitting process that complies with the Solar Rights Act and AB 2188 (Chapter 521, Statutes of 2014), aimed at timely, cost-effective installation of small residential rooftop solar systems while still protecting public health and safety. Sec. 010 defines the covered systems as no larger than ten kilowatts alternating-current nameplate rating or 30 kilowatts thermal, installed on a single-family or duplex dwelling, and meeting all applicable state fire, structural and electrical codes. Sec. 030 applies the chapter citywide and grandfathers systems permitted before the ordinance took effect unless a later modification materially changes the system's size, type or components; routine maintenance and like-kind replacement never require a new permit.
Sec. 050 requires the building division to post every required application document on the city website, accept electronic submittal by email or internet, honor electronic signatures in place of a wet signature, and adopt a standard plan and checklist that substantially conforms to the state's California Solar Permitting Guidebook. 55, 66015 and 66016 and Health and Safety Code Section 17951, capping what the city can charge beyond its actual cost of processing the application.
Violations & Fines
The building official can require a discretionary use permit only where substantial evidence shows a specific, adverse impact on public health or safety, and any denial must rest on written findings and cannot be based on cost or efficiency alone; Civil Code Section 714(d)(1)(A)-(B) treats a cost increase over ten percent of system cost (or $1,000, whichever is less), or a ten percent efficiency loss, as the threshold for a significant restriction. Applicants can appeal any use-permit denial to the planning and transportation commission.
