Boulder FAQ
Do I need a permit to install an EV charger at home?

Longmont FAQ
Do I need a permit to install a home EV charger in Longmont?
Yes. Installing a Level 2 (240V) home EV charger requires an electrical permit through the Longmont Building Division and coordination with Longmont Power & Communications (LPC) if your existing service panel does not have capacity. The city's Electric Service and EV Application is the starting point; review typically takes one to two weeks if existing service is sufficient, one to two months if a service upgrade is needed. Call Planning and Development Services at 303-651-8330.
Does Longmont require new apartments to be EV-ready?
Yes, through Colorado state law. HB23-1233, enacted in 2023, requires multifamily buildings to provide a defined percentage of EV-ready parking spaces - including Level 2 conduit and panel capacity - and prohibits HOAs and landlords from unreasonably blocking EV charging installations. The multifamily compliance milestone took effect March 1, 2024 and is enforced in Longmont through the adopted state building codes alongside Title 15 of the Longmont Municipal Code.
