Wilton is building some housing, which is good, but the town government of Wilton is notoriously anti-growth and anti-more homes.

90% of the land in Wilton requires that homeowners have at least 2 acres of land for each home. They also have been blocking the expansion of their sewer system to allow for denser developments near their train stations, even when developers are willing to pay the entire cost of extending that sewer line.

Wilton doesn’t simply need “affordable” housing, but housing for the people that ASML is hiring without those employees needing to displace current residents in order to move in. Developers desperately want to build these homes and can make a big profit by building them. But Wilton blocks them, so new ASML hires either need to displace current residents (driving up rents and home prices) or make excessively long commutes making traffic worse for everyone.
