Affordable Housing in Germany - A Taxonomy of Acceptance at Federal, State, and Local Levels

The increasing complexity of issues relating to the availability of affordable housing in Germany demands a sophisticated understanding of public sensitivities and policy frameworks. The study applies a grounded theory methodology to explore how the acceptance of affordable housing is shaped at the federal, state, and local levels. The data is systematically coded and compared based on eleven in-depth expert interviews, with the aim of creating a taxonomy of acceptance consisting of four dimensions: governmental issues, public debate and image, solidarity and responsibility, and promotion the right on housing. The analysis indicates that subsidies and political will are essential, but these factors alone cannot ensure long-term sustainability without the presence of stable regulations, the involvement of communities in planning, and strategies to reduce stigmatisation. Historical stereotypes and selective media coverage continue to hinder acceptance, but grounded theory shows how solidarity, discourse and a rights-based framework can reframe housing as a social good. The study demonstrates that acceptance is more than merely a technical problem-solving process; rather, it is a systemic and comprehensive process. By redefining housing as a fundamental right and cornerstone of urban diversity, this research invites stakeholders to view affordable housing not as residual welfare, but as essential infrastructure for social justice and a sustainable urban future.
