Connecticut Zoning & Land Use Laws

Connecticut ADU Law

Connecticut has a statewide ADU law — Connecticut Public Act 21-29 — An Act Concerning Zoning and Affordable Housing — effective 2021-07-01. This law preempts local ordinances — cities and counties cannot impose restrictions stricter than the state standard. Key provisions include: Requires municipalities to permit accessory dwelling units as of right in all residential zones; Municipalities may not prohibit ADUs on owner-occupied single-family residential lots; ADUs must be permitted ministerially — no discretionary review or public hearing required, and 5 more. The most recent amendment was PA 21-29 (2021): Required all Connecticut municipalities to permit ADUs by-right on owner-occupied single-family lots in residential zones. Municipalities must adopt local ADU ordinances compliant with state law. Eliminated the ability of towns to ban ADUs outright in residential zones.

Cottage Food Law

Connecticut Cottage Food Law (Connecticut General Statutes Section 21a-62b): Permits home-based production and direct sale of non-potentially-hazardous foods. Eligible products include baked goods, jams, jellies, candy, dried herbs, and similar shelf-stable items. Annual gross sales limit of $25,000 per year. Sales must be direct to consumers — no wholesale or retail distribution. Labeling must include producer name and address, product name, ingredients list, net weight, and the statement 'Made in a home kitchen not inspected by the Connecticut Department of Consumer Protection.' Registration with the Department of Consumer Protection is required before beginning operations. Connecticut's cottage food law allows home kitchens to operate without a standard food service license, but registration is mandatory. Operations above the $25,000 annual cap require full commercial kitchen licensing.
