Zoning & HOA Considerations
EV chargers in private garages or driveways rarely trigger zoning review. Outdoor pedestal chargers may have setback requirements in some jurisdictions. California AB 1236 prohibits requiring a planning permit for residential EV charger installations, building official review only.
If you live in an HOA community: most states with "right to charge" laws (CA, CO, FL, HI, MD, NY, OR, VA) prohibit HOAs from blocking EV charger installation in a resident's exclusive-use parking space. Even in these states, HOAs may still set reasonable aesthetic and placement standards. Check your state law and CC&Rs before installing.
