Public discussion regarding the political dispute over the socialisation of large housing companies in Berlin primarily frames it as a tool for curbing housing costs. However, an in-depth examination of the programmatic foundations makes clear that it fundamentally concerns a radical realignment of property relations in the housing market. Munich lawyer Dr Christoph Brandenburg, founder of the law firm Brandenburg.Legal specialising in public construction and planning law, points to this connection.
The constitutional point of reference is Article 15 of the Basic Law, which permits the transfer of land, natural resources and means of production into public ownership or other forms of collective economy. The provision dates from a period when the economic order of the Federal Republic of Germany was still subject to fundamental debate; in 1947, for instance, the CDU called for the socialisation of major industrial sectors in its Ahlen Programme. In 1954, the Federal Constitutional Court confirmed that the Basic Law does not prescribe any specific economic system. Since 1949, however, the article has never actually been applied in practice.
Programmatic parallels and housing policy demands
Brandenburg highlights striking substantive similarities between current programmes and older concepts. Publications by the Interventionist Left from 2012 and 2018 explicitly aimed at abolishing the private housing market by dampening the profitability of private portfolios through tenancy law and tax regulations, thereby facilitating acquisition by collective or non-profit entities. Comparable approaches are found in the election manifesto of the Berlin Left Party for the House of Representatives election on 20 September 2026, which calls for a socialisation act as a deliberate break with private commercial logic.
- —Abolition of the modernisation levy and restrictions on share deals
- —Increase of real estate transfer tax from six to eight per cent
- —Reintroduction of a municipal right of pre-emption based on reduced, public-welfare-oriented price levels
- —Demand for the decriminalisation of squatting
Impact on planning certainty and investments
In the view of the lawyer, who served as managing director of a project development company for around ten years before establishing his firm and managed Berlin housing portfolios in that capacity, this course entails significant risks for planning certainty. The experience surrounding the Berlin rent cap, which was declared void by the Federal Constitutional Court in 2021 due to a lack of legislative competence on the part of the state, illustrates the market's sensitivity to regulatory interventions.
Decisions in the housing sector are typically made for decades. If private-sector management structures are fundamentally called into question, this permanently alters valuation bases and investment decisions. Brandenburg therefore advocates not narrowing the debate to rent pricing issues, but instead transparently addressing the far-reaching intentions regarding the future property ownership order.
