Public Act 21-29 Regional Survey

Public Act 21-29 Regional Survey: Accessory Dwelling Units & Commission Training

Public Act 21-29 requires Connecticut cities and towns to allow accessory dwelling units (ADUs) by-right and limits how many parking spaces must be provided for such units. The Act also requires ongoing training for various land use commissioners.

In late December, 2022, CRCOG surveyed the region’s planning directors to better understand how each municipality is approaching the opt-out provisions for ADUs and parking minimums, as well as gain a better understanding of what types of land use commissioner training would be most beneficial. The report includes those responses received by March 2023; please be aware that municipalities may have taken additional actions since that time.
