Summary
Maricopa County doesn't require EV charging spaces in parking lots. Instead, the Travel Reduction Program lets major employers earn plan credit for installing on-site charging stations that power employees' personal vehicles.
Credit will only be given for EVCSs used to power non-fleet passenger vehicles. ... Credit will not be given to employers for employee owned EVCSs that are not located on an employer’s premises.
Full Breakdown
Under Ordinance P-7, employers with 50 or more employees in Area A (the Phoenix-area nonattainment zone) or 100 or more elsewhere in Maricopa County must run a travel reduction plan through the county's Travel Reduction Program. Employers who install an electric vehicle charging station (EVCS) on their property can request dollar-for-dollar plan credit for the station, installation, activation, monthly electricity, warranty, maintenance, and parking-spot signage costs - but only for EVCSs charging non-fleet passenger vehicles, and only if the station sits on the employer's own premises. The TRP Regional Task Force administers and audits the credit.
Violations & Fines
Skipping an EVCS costs nothing - it's optional. But major employers who ignore the Travel Reduction Program altogether face a notice of violation and civil penalties from the Task Force.
