This chapter applies to the permitting of all electrical vehicle charging systems in the city. Electrical vehicle charging systems legally established or permitted prior to the effective date of 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 an electric vehicle charging system in such a way as to require a new permit. Routine operation and maintenance shall not require a permit. (Ord. 687 §1, 2017).
