The Colorado Energy Code Board (Board) must develop a model EV-ready building code for counties, municipalities, and state agencies by June 1, 2023. Members of the Board are appointed by the Director of the Colorado Energy Office. The Board must include the following elements in the model building code:

  • EV-ready and EV-capable requirements for commercial and residential buildings;
  • EV-ready, EV-capable, and EV charging station installation requirements for 20% or more parking spaces at multifamily and commercial buildings;
  • Pre-wiring requirements for single-family residential buildings, multifamily, and commercial buildings

Building codes must consider the cost-effectiveness of pre-wiring for EV charging stations. At a minimum, EV ready parking spaces must have electrical panel capacity, raceway wiring, a receptacle, and a circuit overprotection devise to support an EV charging station with a minimum capacity of 208V.
