Overview of the Study
This report, titled “Affordable Housing in Germany – A Taxonomy of Acceptance at Federal, State, and Local Levels,” is authored by Brigitte Steinhoff, a researcher affiliated with the Munich Personal RePEc Archive (MPRA). The MPRA is a recognised repository for economic research papers, and the study was published in September 2025. It presents a grounded‑theory investigation into how affordable housing is perceived and accepted across Germany’s three levels of government.
Policy Context and Government Targets
The German federal government has set a target of constructing 400,000 affordable housing units per year. In 2024, only 252,000 units were completed, and projections from the ifo Institute suggest a possible decline to 175,000 units in 2025. Building permits fell by 57.6 % in 2024 compared with 2021, reflecting a tightening of the supply pipeline. Subsidy programmes and political will are identified as essential, yet insufficient without stable regulations, community involvement, and stigma reduction.
Research Methodology
The study employed grounded theory, analysing eleven semi‑structured expert interviews with professionals from federal, state, and municipal housing agencies. Coding yielded 846 first‑order codes, organised into eight theoretical categories that aggregate into four dimensions of acceptance: governmental issues, public debate and image, solidarity and responsibility, and promotion of the right to housing. The participant pool comprised six women and seven men, representing a geographically balanced sample across Germany.
Key Findings: Acceptance Dimensions
- Governmental Issues – 18.09 % of coded material highlighted the importance of reliable funding (e.g., €2.2 billion in housing subsidies) and consistent regulatory frameworks.
- Public Debate and Image – Media framing and historical stereotypes (e.g., 1960s‑70s social‑housing estates) continue to shape public perception, with only 5.56 % of codes directly addressing media influence.
- Solidarity and Responsibility – The strongest theme (22.22 % of codes) underscores housing as a basic human need and a collective societal duty.
- Promotion of the Right to Housing – 11.23 % of codes stress legal recognition of housing as a fundamental right, comparable to education and healthcare.
Quantitative Highlights
- 846 distinct coding segments were identified.
- 188 segments (22.22 %) pertained to solidarity.
- 153 segments (18.09 %) related to governmental issues.
- The study records four dimensions that overlap, forming a systemic taxonomy of acceptance.
Stakeholder Involvement and Community Strategies
Interviewees cited successful practices such as mixed‑use developments that blend subsidised units with market housing, participatory planning events, and community‑building initiatives (e.g., urban gardening, shared social spaces). These approaches aim to mitigate the “not‑in‑my‑backyard” (NIMBY) sentiment and foster everyday interaction among residents.
Implications for Sustainable Housing Policy
The authors argue that technical measures alone (subsidies, construction targets) cannot secure long‑term acceptance. Sustainable outcomes require:
- Stable, multi‑year funding commitments;
- Transparent communication and media strategies to reshape public image;
- Legal reinforcement of the right to housing; and
- Integrated solidarity mechanisms, such as mandatory affordable‑housing quotas in all neighbourhoods.
Recommendations for Future Research
The report calls for larger‑scale quantitative surveys to complement the qualitative insights, comparative studies across European contexts, and experimental evaluations of framing techniques that influence public opinion. It also stresses the need for standardised definitions of “affordable housing” to enhance policy comparability.
Relevance to a Pan‑European Audience
While the study focuses on Germany, its taxonomy of acceptance is applicable to other European nations facing similar housing shortages, rising construction costs, and public resistance. The identified dimensions provide a framework for policymakers, urban planners, and sustainability advocates to design housing programmes that are financially viable, socially legitimate, and environmentally responsible.
