Cities throughout California may see a perceptible transformation of their urban design in the coming years, under a new law signed by Gov. Gavin Newsom to authorize dense housing around transit hubs. Senate Bill 79, which the governor approved on Friday morning, will change zoning standards around train stations, ferry terminals and bus rapid transit stops, allowing apartment buildings and other multifamily homes up to nine stories. The law will also loosen height restrictions within a half mile radius of these transportation hubs.
