New construction requires EV-ready wiring. ARS 33-1818 prohibits HOAs from banning homeowner EV charger installation. Level 2 chargers need an electrical permit.
Oro Valley follows the International Building Code and International Residential Code as adopted by the town for EV infrastructure requirements in new construction. New single-family homes must include EV-ready wiring (240-volt outlet in the garage) per current code adoptions. Commercial developments may be required to provide a percentage of EV-capable parking spaces based on project size. The town has installed Level 2 EV charging stations at municipal facilities including Town Hall and community centers. Arizona Revised Statutes Section 33-1818 (enacted 2022) prohibits HOAs from banning the installation of EV charging equipment on a homeowner's property, though HOAs may establish reasonable architectural standards for equipment placement and appearance. Homeowners installing Level 2 chargers (240V, 40-50 amp) typically need an electrical permit. Tucson Electric Power (TEP), the utility serving Oro Valley, offers time-of-use rate plans that incentivize off-peak EV charging. Public DC fast-charging stations are available along Oracle Road commercial corridors.
Unpermitted electrical work for charger installation: code enforcement with notice to obtain permit. HOAs that ban EV charger installation are in violation of ARS 33-1818.
