It is rent control - which basically exists throughout Germany. Even in SF rent controlled apartments can increase some % per year, it is just controlled how much. In Germany this is often done by looking at the region's average price for similar properties and then fixing some limited increase against that. This is distinct from the rent cap that was overturned, which stated no rise in rent at all for five years.
