Maui County, HI Parking Rules: EV Charging (2026)

1. For residential multiunit projects adding eight or more new stalls, seventy percent of the added stalls must be "electric vehicle capable," at least twenty percent must be "electric vehicle charger ready," and at least ten percent must have chargers actually installed and operational. Commercial projects adding ten or more new stalls must make forty percent of the new stalls capable, with at least ten percent carrying operational chargers. Alterations trigger the same requirements when the work area exceeds fifty percent of the original building area or more than ten parking spaces are substantially modified.

The code defines "electric vehicle charger ready" as having the wire, conduit, panel capacity, overcurrent protection, and termination points needed for a Level 2 charging station, while "electric vehicle capable" means only the conduit is in place. Exceptions soften the mandate: multi-use and commercial projects can substitute one 20-kilowatt DC fast-charging space for up to seven Level 2 spaces; retail establishments get a twenty percent reduction in required stalls; affordable units for households between 100 and 140 percent of area median income get a fifty percent reduction; and units for households at or below 100 percent of area median income are exempt entirely. The requirement was added by Ordinance No. 5455 in 2022 as part of the county's adoption of the Hawaiʻi State Energy Code.
