What’s Changing for ADUs with Public Act 21-29?

With Public Act 21-29, Connecticut’s stance on ADUs has shifted significantly. The law now requires that all municipalities allow ADUs as a right on single-family properties. This means homeowners no longer need special permits or variances to construct an ADU. However, municipalities do have the option to opt-out if they already have ADU provisions in place or wish to develop their own regulations.

Key Changes:

ADUs are allowed by right on single-family properties.
Municipalities can opt-out of this provision, but only under specific circumstances.
ADUs do not count towards affordable housing calculations under the Affordable Housing Land Use Appeals Procedure.
