Proposed housing solutions, Chicago transit in peril, and executive actions in limbo.

The housing crisis, at its various scales, took center stage for Planetizen readers last month: While Florida could legalize ADUs statewide, San Diego is reining in its rules, which allowed developers to build multi-story, multi-unit buildings that some residents said were not the intended result of the law. Meanwhile, a crucial source of affordable housing, mobile home parks, is losing ground to investors. HUD announced a plan to explore housing development on federal lands, though many of these are far from the urban centers where housing is most sorely needed, and California’s shelter system reveals major gaps in service and safety. Chicago-area transit leaders warn that without additional funding, their agencies could face severe cuts, kneecapping the regional economy. And Volkswagen brings a new look to the van that defined the hippie era with the electric re-release of its iconic VW bus.
