The Waterbury Development Corp. Board, working with the Naugatuck Valley Council of Governments (NVCOG), has assembled brownfield cleanup grants targeting the city's south-end industrial sites — including the former Anaconda American Brass site on Freight Street, the Anamet site along South Main Street, and the Brass City Harvest food hub expansion on Mill and South Main. These projects are remediated and rezoned under state-approved brownfield workflows.

Connecticut Public Act 21-29 (HB 6107, 2021) amended CGS § 8-2 to require municipalities to allow accessory dwelling units (up to 1,000 sq ft or 30% of the primary dwelling) as of right on lots with single-family homes, unless the municipality formally opted out by a 2/3 vote of its zoning commission before January 1, 2023. Confirm with Waterbury's Zoning Commission whether the City opted out and how local ADU standards are codified.

Waterbury is subject to CGS § 8-30g, Connecticut's affordable-housing land-use appeals procedure (Chapter 126a of the General Statutes). The statute creates an appeal path for affordable-housing developers when fewer than 10% of a municipality's housing units qualify as affordable and no moratorium is in effect.
