Connecticut hearing turns to clash over SB 151 as towns, builders and advocates disagree on lot‑size reform

Summary
Lawmakers heard competing views on Senate Bill 151, a proposal to cap minimum lot sizes and loosen setback and coverage rules in parts of Connecticut. Supporters say the measure would unlock 'starter' and senior homes where water and sewer exist; opponents — mayors, first selectmen and conservation groups — warn of flooding, sewer and school impacts and loss of local planning authority.
A heated public hearing in front of the Connecticut General Assembly’s Housing Committee on SB 151 laid bare deep divisions over how to expand housing.
Supporters, including developers, housing advocates and the Regional Plan Association, told panelists that large minimum‑lot rules and strict setback and coverage limits have made smaller, starter homes scarce and driven up land costs. Pete Harrison of the Pro‑Homes Connecticut coalition said the state’s zoning effectively requires an acre or more on much residential land and that reducing minimum lot sizes in places served by public water and sewer would produce infill starter homes and help younger buyers and seniors downsize.
‘‘Minimum lot size requirements and excessive setbacks have pushed land costs higher and shrunk housing supply,’’ Harrison said in testimony.
Opponents ranged from municipal leaders to environmental advocates and residents. Greenwich First Selectman Fred Camillo told the committee his town has spent ‘‘millions’’ on stormwater mitigation, warned that removing setback and coverage limits could intensify impervious‑surface runoff and magnify local flooding and sewer demands, and urged the Legislature to work with towns rather than preempt local rules. Multiple small‑town leaders and the Connecticut Council of Small Towns argued SB 151 would force municipalities to bear unfunded infrastructure costs and undercut local plans to protect wetlands and public safety.
‘‘When you change setbacks and compel townhouses in single‑family zones, you are adding impervious surface and you risk undoing millions spent to mitigate flooding,’’ Camillo said.
Committee members and witnesses debated whether the bill is meant to create ‘‘starter homes’’ and senior units — as some backers insist — or whether it would allow subdivision and dense redevelopment that local officials cannot safely accommodate without added resources. Senator Ryan Fazio and other legislators urged alternatives such as reducing property‑tax burdens, expanding trades workforce capacity and revising licensing to lower construction costs, rather than sweeping statewide preemption.
The bill includes carve‑outs in practice: several proponents emphasized that the proposal targets lots with existing or planned public water and sewer. Attorneys and some land‑use experts told the committee that existing building, fire and stormwater laws would still apply, and that not every subdivided lot would be buildable if infrastructure cannot support it. But many municipal officials said those safeguards are insufficient without new funding and coordinated planning.
The hearing produced partisan and cross‑interest alignments: local officials and conservation groups opposed SB 151; builders, planners and housing advocates supported it; and several legislators asked for technical clarifications and potential amendments to protect infrastructure capacity. No committee vote was taken at the hearing.
What happens next: the Housing Committee has not set a final mark‑up. Lawmakers said they will consider technical fixes, including clearer language about where the measure would apply, and whether to require infrastructure capacity demonstrations or funding offsets before changes take effect.
