Research notes
Limited teeth — much of the original DesegregateCT-backed preemption language was stripped during legislative negotiation. PA 21-29 codified procedural reforms (mandatory training for land use officials, requirement that every municipality adopt an affordable housing plan every five years), an opt-out ADU framework, and amendments to §8-2 to require plain-language regulations and remove character-of-the-neighborhood as a basis for denial. It does NOT establish enforceable fair-share allocations comparable to New Jersey's Mount Laurel doctrine or California's RHNA. Compliance with the affordable housing plan requirement is largely self-reported with no penalty for non-compliance. Future legislative cycles continue to debate strengthening this framework.
