High mandated standards on Fire/Noise Protection, Insulation, accessibility on new buildings make it really hard to build "cheap" rental apartments. With the mandated standards in place there is little to no cost difference between high cost and low cost residential buildings. Those standards obviously have their benefits or are unavoidable (fire protection) and result in new housing being high quality. But they make it hard to address housing shortages in a non long term way.
