Mannheim in danger: Rent cap threatens to end in 2026!
On November 6, 2025, housing issues will be the focus of Mannheim politics. The Left Mannheim and the local council group LTK are dissatisfied with the current developments with regard to the rent cap. From January 1, 2026, Mannheim will be like that kommunalinfo-mannheim.de reported to fall outside the scope of the rent cap. This means that landlords can increase rents again by up to 20%.
In the last four and a half years, the rent cap has been in effect in Mannheim, which allowed the cap to be limited to a maximum of 10% above the local comparative rent. In order to continue to apply the rent cap, a report from the state must be submitted that meets four of five specific criteria for a tight housing market. However, it currently looks as if Mannheim can no longer comply with this regulation.
Political appeal and demands
Philipp Fränkle, spokesman for the Left in Mannheim, has called on the state government to disclose the methodology and results of the rent cap. He also advocates that three out of five criteria should be sufficient to determine the need for a rent cap. Anna Roth, spokeswoman for the Mannheim Left, fears that the abolition of the rent cap could lead to an even greater increase in rents.
The new legal situation also brings with it ambiguities: It is unclear whether shared rooms, which make up a significant share of the rental housing market in Mannheim, will be taken into account when determining the criteria. “This shouldn’t be ignored,” says Roth.
Reactions from the region
Uli Burchardt, Mayor of Konstanz (CDU), spoke in a similar context. He criticizes the methodology that also led to his city's removal from the rent control system. Burchardt therefore supports the nationwide appeal for a sustainable design of the rent control area.
Dennis Ulas, Left-wing city councilor and housing policy spokesman for the LTK, also does not hesitate to encourage the affected municipalities to take legal action in an emergency to reinstate the rent cap. “It’s not just Mannheim’s future that plays a role here, but that of all affected cities in Baden-Württemberg,” said Ulas.
Meanwhile, State Construction Minister Nicole Razavi hopes that the rent cap will no longer need to be extended after 2029 anyway. A positive outlook, but many citizens and local politicians are skeptical.
