Starting in 2026, California will implement comprehensive building code requirements to significantly expand electric vehicle (EV) charging capabilities across new residential and commercial properties.
The new regulations represent a strategic approach to supporting the state’s transition to electric transportation.
Residential Charging Requirements
Multi-Family Residential Developments
The new codes will require at least one EV-ready parking space per residential unit. An “EV Ready” space is defined as having a 240V/20A outlet or charger, compatible with standardized outlets (NEMA 6-20, 14-30, or 14-50) or J1772 and J3400 (NACS) charging standards.
Key provisions include:
- For dedicated parking spaces: Spaces should be on a separate circuit wired to the unit’s electrical panel when feasible
- For shared parking: At least one EV-ready space per unit
- When parking spaces exceed the number of units: 25% of excess spaces must be EV-ready, with potential for local jurisdictions to increase this requirement
Charging Infrastructure Flexibility
The regulations allow for innovative power-sharing solutions, ensuring a minimum of 3.3kW can be simultaneously provided to each unit.
One recent condo project demonstrated the cost-effectiveness of such implementations, with installation costs around $405 per space after utility incentives.
Expanded Charging Requirements Beyond Residential Spaces
Hotel and Motel Parking
- Minimum of 65% EV-ready parking spaces
- Local jurisdictions can increase the requirement up to 100%
Commercial and Retail Parking
- 20% of spaces must be EV-ready
- Potential for local increases to 30% or 45%
- DC fast charging installations may provide additional compliance credits
Comprehensive Implementation Strategy
Broader Scope of Application
The regulations extend beyond new developments to include:
- Any added parking spaces in existing developments
- Parking spaces modified under building permits
- New solar canopy parking projects
Exemptions and Nuances
- Retrofits adding Level 1 charging are exempt from minimum service requirements
- The codes provide flexibility while maintaining a clear path to increased EV infrastructure
Advocacy and Industry Response
The new building codes emerged from collaborative efforts between environmental advocates and industry stakeholders.
Organizations like the EV Charging for All Coalition (EVCAC) and Peninsula Clean Energy played crucial roles in pushing for these progressive regulations.
Sven Thesen, an EVCAC co-founder, emphasized the approach’s balanced nature:
“The focus was on right-sizing installations, allowing for power-sharing and varied charging options to ensure accessibility without unnecessary oversizing.”
Thesen said to Electrek’s team.
Strategic Alignment with California’s EV Goals
These building codes are strategically timed to support California’s ambitious goal of ensuring all new car sales include a plug by 2035.
By implementing infrastructure requirements in advance, the state is proactively addressing potential charging challenges.
