Housing association Vivawest has completed modernisation work on its properties in the Alstaden district of Oberhausen. The refurbishment covered multiple residential buildings in the area. Tenants now face potential rent increases, as German law allows landlords to pass on a portion of modernisation costs through annual rent adjustments of up to 8 per cent of the investment sum. Vivawest has not yet disclosed specific details about the scope of improvements or planned rent modifications for affected households.
