The solutions to expensive housing is complicated, obviously. Its about zoning, cancelling out NIMBYism, incentivizing affordable housing and basically matching supply with demand.
Rent control simply doesn't work. For any person it helps, it will disadvantage 10x more in the process.
I wonder if they are putting in vacancy controls as well. That would have the 1-2 punch of not only reducing rental stock but also significantly lowering property values (and property taxes in the process)
