Should the state allow local governments to control zoning and housing density decisions?
Connecticut municipalities face a June 1, 2028, deadline to submit housing development plans as part of a state-wide regulatory effort. Operators in commercial development should note that these mandates require local zoning changes to accommodate two-to-nine-unit middle housing projects.
Why it matters
The state's housing initiative aims to increase supply by forcing towns to prioritize residential density in commercial zones, a move that fundamentally changes how commercial land can be leveraged. This shift follows Eversource's $2.4 billion divestment of Aquarion Water Company, which was completed in June 2026 to address debt from offshore wind investments.
Connecticut’s 169 municipalities must now allow two-to-nine-unit middle housing in commercial zones. The state also eliminated minimum parking requirements for developments with 16 or fewer units, while water infrastructure capacity remains a factor following the $2.4 billion sale of Aquarion.
The players
South-Central Connecticut Regional Water Authority
A public utility provider that significantly expanded its regional water service footprint through a $2.4 billion acquisition in 2026.
Eversource
A major investor-owned utility company that sold its water subsidiary to manage capital obligations from offshore wind investments.
The details
Under the new mandate, municipalities must coordinate with regional Councils of Government to identify specific zones for residential growth. Developers will benefit from a removal of minimum parking requirements for projects with 16 or fewer units, lowering construction costs and land-use intensity. Projects must be integrated into regional infrastructure plans, a process that requires alignment between developers and municipal planners before the 2028 deadline.
Timeline
June 2026: The South-Central Connecticut Regional Water Authority completed the $2.4 billion acquisition of Aquarion Water Company.
June 1, 2028: Municipalities must finalize and submit their housing development plans to state authorities.
Market Landscape
The push for middle housing follows a period of significant utility consolidation within the state, most notably the $2.4 billion transfer of Aquarion Water Company assets. These mandates align with broader efforts to unlock commercial zones for residential use to counter regional housing shortages.
Developers and commercial property owners should prepare for changes to local zoning codes that will allow for residential use on existing commercial plots. Review local parking requirements immediately, as the 16-unit exemption threshold offers new opportunities to maximize land yield on smaller projects.
The takeaway
The move to open commercial zones for multi-unit housing creates a clear incentive for property conversion before the 2028 deadline. Owners should track their specific town's coordination with regional Councils of Government to understand how local utility capacity might restrict or favor specific site density.
