Full Breakdown
Napa's EV-charging framework runs through three layers. (1) State building standards: the California Green Building Standards Code (CALGreen, Title 24 Part 11) mandatory provisions set EV-ready and EV-charging requirements for new construction. 4 (residential) requires new one- and two-family dwellings and townhouses to install at least one EV-ready parking space with a 40-amp, 208/240-volt branch circuit terminating at a junction box or NEMA 14-50 receptacle at the future charger location. 8 voluntary tier sets enhanced standards. 3 (nonresidential / multifamily) requires percentages of EV-capable, EV-ready, and EV-charging-station spaces that scale up with each code cycle.
The 2025 CALGreen cycle (effective January 1, 2026) further increases multifamily requirements. (2) Local adoption and expedited permitting: Napa Municipal Code Title 15 adopts the California Building Standards Code including CALGreen. 7, requiring a Building Permit Application, three sets of plans, plans prepared or stamped by a California-licensed Electrical Engineer or C-10 Electrical Contractor, and an electrical load calculation per California Electrical Code §220. Plans must meet CEC Article 625 for EV charging systems. (3) State EV-space protection / HOA law: California Vehicle Code §22511 reserves posted EV-charging spaces for vehicles actively charging, non-EVs and EVs not actively charging may be cited. 6.
Violations & Fines
New residential or commercial construction in Napa that fails to install the CALGreen-required EV-capable, EV-ready, or EV-charging-station spaces cannot pass final building inspection through the Napa Community Development Department. Installing a Level 2 home charger, sub-panel, or dedicated branch circuit without an electrical permit is a building-code violation enforceable with stop-work orders and corrective-permit requirements. Parking a non-EV in a posted EV-charging space, or an EV not actively charging, is citable under California Vehicle Code §22511. HOAs that violate Civil Code §4745 by denying owner EVSE installations face civil liability including attorney's fees.
