State Zoning Bill Targeting Local Lot-Size and Setback Rules Advances at Capitol
HARTFORD — A state zoning bill that would sharply limit Fairfield’s ability to enforce several core residential land-use rules has cleared the Connecticut General Assembly’s Housing Committee and now awaits potential action by the full legislature before the session ends May 6.
Senate Bill 151 — titled “An Act Prohibiting Certain Land Use and Zoning Limitations on Housing” — would prohibit municipalities from enforcing a range of zoning standards affecting one-family homes and townhouses in areas served by public water and sewer.
The Housing Committee held a public hearing on the measure February 17 and voted to advance the bill March 10.
If enacted, the legislation would override several local zoning tools widely used in Fairfield and other Connecticut suburbs, including minimum lot sizes, dimensional standards, and restrictions on housing types.
What the Bill Would Change
Under SB 151, municipalities could not impose several categories of zoning requirements that currently shape the layout and density of residential neighborhoods.
Among the provisions most discussed in testimony:
• Minimum lot sizes could not exceed 5,000 square feet in covered areas.
• Setback requirements for front, rear, and side yards would be limited by state law.
• Townhouses could not be prohibited in zones currently restricted to single-family homes.
• Subdivision restrictions preventing certain residential lot splits would also be curtailed.
The bill applies to areas served by — or planned to be served by — public water and sewer infrastructure, meaning much of Fairfield’s developed land area could fall within its scope.
Local zoning in Fairfield currently relies heavily on dimensional standards such as lot size and setbacks to regulate development intensity.
Debate at the Housing Committee
The proposal drew sharp disagreement during the February public hearing.
The Connecticut Council of Small Towns (COST) urged lawmakers to reject the bill, arguing that it would override local planning authority and could create infrastructure and environmental challenges.
Supporters argued that Connecticut’s zoning rules are restricting housing production.
In testimony supporting the bill, housing advocates cited research estimating that more than 4,700 proposed homes were blocked during Connecticut’s permitting process in 2023, representing about 46 percent of proposed units statewide.
That figure comes from advocacy research submitted to the committee rather than a state statistical report.
Separate From the State’s New Housing Law
SB 151 is separate from HB 8002, the omnibus housing legislation passed during the November 2025 special session and signed by Governor Ned Lamont.
That law already imposes several statewide housing policy changes.
Beginning July 1, 2026, municipalities must allow “transit community middle housing” — residential buildings containing two to nine units — on parcels zoned for commercial or mixed-use development through a summary administrative review process.
The law does not require middle housing on all residential lots statewide, but it creates a new framework intended to expand housing production near transit and commercial areas.
HB 8002 also requires municipalities with populations above 15,000 residents to establish or participate in a Fair Rent Commission by January 1, 2028.
Fairfield already has such a commission under Chapter 87 of the town code.
What Happens Next
With Housing Committee approval, SB 151 is now eligible for consideration by the full General Assembly.
Connecticut’s 2026 legislative session adjourns May 6. If the bill does not pass both chambers before that date, it would not become law this year.

CORRECTION to an earlier post that misinterpreted the March 10 CT Mirror article that said leaders described that meeting as "what they expected to be the last Housing Committee meeting of the session", implying that bills not already advanced were therefore dead. We are committed to accuracy and retract any previously published incorrect information.
