Funding Program for Housing and Modernization

The funding program of Investitionsbank Berlin (IBB) is aimed at private individuals, companies, cooperatives, and public institutions with residence or property ownership in Berlin. The focus is on energy-efficient building renovations, barrier-reducing construction measures, age-appropriate conversions, as well as rent subsidies and the acquisition of cooperative shares. As a grant program, IBB supports landlords, investors, owner-occupiers, and homeowners' associations in increasing living comfort, improving energy efficiency, and reducing energy costs in the long term. By combining various funding instruments, modernization and renovation projects can be optimally implemented and fully financed – including the integration of renewable energies and climate-friendly heating technologies.

Applications can be submitted continuously at any time via the IBB customer portal. A prerequisite for funding is proof of the planned measures as well as personal contribution or equity participation. Eligible expenses include insulation, optimized heating systems, elevator retrofitting, pathway construction, barrier-free bathrooms, as well as subsidies for rent reduction and cooperative share acquisition. The program contributes to making urban infrastructure future-proof and addressing demographic change. Through the sustainable development of Berlin’s housing stock, investment incentives are created and social housing quality is strengthened – an important contribution to an inclusive, energy-saving, and livable Berlin.
