16.28.010 Purpose and Intent.¶
The purpose of this Chapter is:
i. 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. The Ordinance expands AB2188 to provide for timely and cost-effective installations of solar panels on small multi-family and commercial buildings. The Ordinance 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. The Ordinance allows the City to achieve these goals while protecting the public health and safety.
ii. To promote and encourage the use of electric vehicles by creating an expedited, streamlined permitting process for electric vehicle charging stations while promoting public health and safety and preventing specific adverse impacts in the installation and use of such charging stations.

16.28.030 Applicability.¶
a. This Chapter applies to the permitting of all small rooftop solar energy systems and electric vehicle charging systems in the City.
b. Small rooftop solar energy systems and electric vehicle charging systems legally established or permitted prior to the effective date of this Ordinance are not subject to the requirements of this Ordinance 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.
