Tucson, AZ Parking Rules: EV Charging (2026)

11 of the Unified Development Code sets minimum electric-vehicle-supply-equipment requirements as a percentage of required off-street motor vehicle parking, calculated after any approved parking reductions or modifications. 11-1 sets three tiers for the Multifamily Dwellings and Group Dwellings use class: no spaces require a fully installed EV Installed charger, 10% of required parking must be EV Ready, and 20% must be EV Capable. Mobile home developments have a separate standard, one EV Ready space per dwelling unit, with no EV Installed or EV Capable minimum.

12 defines what each tier requires on site: an EV Installed station must be securely anchored and identified with signage and pavement markings bearing an EV symbol, and must be accessible for charging during business hours at minimum. An EV Ready space needs its dedicated outlet permanently marked 'EV Ready' and its branch circuit identified the same way in the service panel directory, so a resident can plug in with their own cable. An EV Capable space only needs the raceway termination and reserved panel capacity marked 'EV Capable' for future buildout, the cheapest tier, meant to future-proof the site without installing conductors yet.

2 layers on an accessibility requirement: at least 4% of EV charging spaces in any parking facility (never less than one) must also meet accessible parking space design standards, separate from the building's required ADA parking count. 4. These EV provisions were adopted by Ordinance 11953 on August 23, 2022, as part of Tucson's UDC electric-vehicle infrastructure package.
