In a victory for advocates of Connecticut’s affordable housing law, a Superior Court judge has ruled that the New Canaan Planning & Zoning Commission improperly denied a proposal to build a 102-unit apartment complex that included 31 affordable units.

The 98-page decision refuted concerns commonly raised by opponents of such developments and emphasized that all towns bear some responsibility for meeting housing needs in the state.

The ruling, issued in Superior Court in Hartford, says that the planning and zoning commission must approve the construction after the developer makes a couple of minor tweaks to the proposal to build on Weed Street in New Canaan.
