(de-news.net) – The CSU is advocating for swift federal legislation to stop the socialization or expropriation of sizable private housing portfolios. The Left continues to support socialization as part of its housing policy, which could complicate coalition negotiations with the SPD and Greens. Chancellor Friedrich Merz (CDU) is advancing a federal ban. The dispute comes alongside alternative tenant-relief measures, including Baden-Württemberg’s planned extension of its rent cap.
The debate over how to address Germany’s housing costs has gained renewed political significance following the Left Party’s election victory in Berlin, with the CSU pressing for swift federal action to prevent the expropriation or socialization of large privately owned housing portfolios. CSU Secretary-General Martin Huber argued that the Left’s approach would damage the housing market, impose exceptionally high costs and undermine private investment. In his assessment, the policy would fail to add even one new apartment to the housing stock while discouraging investment needed in the sector.
The dispute comes as Chancellor Merz has already moved toward a federal response. The CDU leader has announced legislation intended to prohibit real-estate expropriations and said the Berlin Left’s plans to socialize major property companies were having a damaging effect on investors in Germany and abroad. Preliminary drafts have been prepared for relatively rapid Cabinet consideration, according to Merz, with the proposed legislation intended to establish that the expropriation of private property is not permissible in Germany. The governing CDU/CSU and SPD coalition agreed in July to address the issue through federal law, specifically seeking to prevent state-level socialization legislation from being used to nationalize privately owned rental-housing portfolios.
Berlin’s election result has nevertheless strengthened the political prominence of the issue rather than settling it. The Left has reiterated its support for socializing large real-estate companies as part of its effort to secure affordable housing, according to federal co-chair Ines Schwerdtner. Leading candidate Elif Eralp likewise said the policy would have to be part of any future state government. That position could complicate coalition negotiations with the SPD and Greens. While the Greens have signaled support, the Berlin SPD rejected socialization during the campaign as financially impractical, leaving a significant policy difference among potential coalition partners.
Housing debate extends from Berlin coalition talks to state-level rent controls
The federal initiative has prompted further responses from the Left. Parliamentary leader Sören Pellmann criticized Merz’s proposed legislation as evidence of continued government inaction over rising rents and argued that it failed to reflect the pressures facing tenants. He said the election results had demonstrated public dissatisfaction with what he characterized as an insufficient response to housing costs and accused the chancellor of favoring property owners’ interests over those of tenants.
For the SPD, the question extends beyond the housing policy itself to the broader conditions under which a Berlin coalition could operate. Former Mayor Klaus Wowereit said the viability of a government led by the Left together with the SPD and Greens would depend on whether the parties could establish workable common principles. The SPD, he emphasized, would set conditions for participation, including positions on expropriation and antisemitism. Other governing combinations remain mathematically possible, including a CDU-SPD-Greens alliance, making the Greens’ position an important factor in determining which coalition arrangements can be pursued.
The Berlin debate is unfolding alongside more limited efforts elsewhere to ease pressure on tenants without resorting to expropriation. In Baden-Württemberg, the state government has released draft regulations for public comment as it prepares to extend the rent cap, which is due to expire at the end of the year. The proposed extension would apply the measure in additional cities, including Mannheim and Konstanz. The regulation has been in force since 2015 in areas designated by the state government as having tight housing markets, where newly agreed rents are generally restricted to no more than 10 percent above the local comparative rent, based on applicable rent indexes.
