The act prohibits a municipality that is within a metropolitan planning organization (MPO) or a county that has unincorporated areas within an MPO (local government), on or after June 30, 2025, from enacting or enforcing minimum parking requirements that apply to a land use approval for a multi-family residential development, adaptive re-use for residential purposes, or adaptive re-use mixed-use purposes which include at least 50% of use for residential purposes that is within, as applicable, the unincorporated area of the county or the municipality, within a metropolitan planning organization, and at least partially within an applicable transit service area. An applicable transit service area is an area identified by a map published by the department of local affairs as an area that is one-quarter mile of certain transit stops. The prohibition on enacting or enforcing minimum parking requirements does not lower the protections provided for persons with disabilities or prohibit a local government from: Enacting or enforcing a maximum parking requirement; Enforcing any agreement made before the effective date of the act in connection with a land use approval to provide regulated affordable housing in exchange for reducing minimum parking requirements; Being awarded funding for affordable housing that requires a ratio of a certain number of parking spaces; Enacting or enforcing a minimum parking requirement for bicycles; or Imposing the following requirements on a parking space that is voluntarily provided in connection with a development project: That the owners of such a parking space charge for the use of the space; That the owner of such a parking space contribute to a parking enterprise, permitting system, or shared parking plan; and That such a parking space allow for electric vehicle charging stations in accordance with existing law. Furthermore, notwithstanding the prohibition on enacting or enforcing minimum parking requirements, a local government may impose or enforce a minimum parking requirement in connection with a housing development project that is intended to contain twenty unity or more or contain regulated affordable housing. To impose or enforce such a minimum parking requirement, a county or municipality must publish certain written findings and annually report to the department of local affairs. Lastly, the act requires the department of local affairs: In consultation with the department of transportation, and the Colorado energy office, to develop and publish best practices and technical assistance materials concerning optimizing parking supply and managing parking; and In consultation with the department of transportation, the Colorado energy office, metropolitan planning organizations, and transit agencies that operate within metropolitan planning organizations, to publish a map that designates applicable transit service areas to be used by local governments in complying with the act.
