You could see commercial real-estate be converted to residential.
There is the Valco mall in Cupertino being demolished for mixed use residential, retail and office space. That mall was dying for a decade.
Then there is Santana Row in San Jose. Used to be a strip mall as I recall. Now its high end shopping and residential.
Going more "dorm" style could work for low end if there wasn't a pandemic and even then it would carry plenty of risks that would scare people away from such an arrangement let alone the consumer desires.
