Price controls are generally considered to be inefficient purely from an economic perspective.
However, the free market has generally been a terrible provider of low-income housing solutions. There's a long, long history to this from shanty towns to tenements. That's why basically all developed countries have some type of social housing component from demand-side subsidies to public housing or regulated stock.
When we lose permanently affordable units, it is invariably extraordinarily expensive to replace them given land costs and the size of subsidies that are needed. Contemporary homelessness emerged in the late 1970s and early 1980s in both San Francisco and New York as both cities started to lose single-room occupancy hotels or SROs.
