Full Breakdown
The City adopted the 2024 International Energy Conservation Code, including its Appendix RE - Electric Vehicle Charging Infrastructure, by reference under Section 4-9-1 (Ord. No. 5987, effective December 8, 2025, per Resolution No. 12457). Section 4-9-2 then locally amends that appendix. 1, titled "Quantity," requires new one- and two-family dwellings and townhouses that have a designated attached or detached garage, or other on-site private parking adjacent to the unit, to provide one EV capable, EV ready, or EVSE (electric vehicle supply equipment) parking space per dwelling unit.
For R-2 occupancies, or allocated parking serving R-2 units within mixed-use buildings, the code requires 15 percent of dwelling units or parking spaces (whichever is less) to be EV capable or EV ready, plus 5 percent EVSE spaces. 5 would force a substation upgrade that raises the builder's or developer's utility-side cost by more than $450 per dwelling unit, that added infrastructure is not required. 25.
Violations & Fines
Chapter 4-9 amendments are enforced through the building permit and inspection process administered by the Building Safety Director; a new residential or R-2 project that fails to install the required EV-capable, EV-ready, or EVSE spaces cannot obtain approval or a certificate of occupancy. Chapter violations otherwise fall under the general Title 4 penalty of Section 4-1-9: a class one misdemeanor with a fine up to $2,500 and/or up to six months in jail, each day a separate offense.
