In short, he does not claim that upzoning “doesn’t work.” He says 5 years may have been too short a time to measure the changes in Chicago. He also highlights numerous possible reasons for the Chicago housing price increases that may differ from the California proposals (SB 827 last year, or SB 50 this year): * “it targeted just areas around transit (rather than the city as a whole).” SB 827 and SB 50 are a much broader upzoning. * “it was implemented in a city with relatively affordable housing (rather than very high rents, such as in San Francisco)” * “they should take seriously the concerns of local residents who are worried that their housing costs will increase”. SB 50 exempts tenant-occupied housing and reserves a fraction of the units for low-income households.
