Connecticut — Real 2021 statewide law, but with a unique municipal opt-out (verified 2026-08)
Tiny home on wheelsNo statewide tiny-home-on-wheels law. Connecticut's dense suburban zoning and high land costs make it one of the more difficult Northeast states for tiny homes as a primary residence.
ADU / accessory unitThis corrects an earlier draft that undersold what happened here: Connecticut passed Public Act 21-29 in 2021, a real statewide law requiring towns to allow at least one ADU by right, capped at 1,000 sq ft or 30% of the primary home. What makes Connecticut unusual — unique among the states with ADU laws covered in this dataset — is that towns were allowed to opt out by January 1, 2023. About 115 of Connecticut's roughly 169 towns did opt out, while 54 remained subject to the state law. Importantly, most opt-out towns still allow ADUs under their own separate rules: about 67% of all CT municipalities allow ADUs that at least partially satisfy the original state standard.
Minimum square footageState law caps at 1,000 sq ft or 30% of the primary home in non-opt-out towns; opt-out towns set their own rules
Foundation requirementFoundation-built ADUs have the most viable path; whether the state's simplified rules or a town's own ordinance applies depends entirely on that town's 2023 opt-out decision
Local notesThe single most important thing to check in Connecticut is whether the specific town opted out of PA 21-29 — that determines which rulebook actually applies, more than any other factor in this entry.
