Berlin state housing firms raise rents for 90,000 households after election

Rent adjustments across municipal housing

Berlin's seven state-owned housing companies are sending rent increase notices to approximately 90,000 of their more than 400,000 tenant households throughout 2026. The monthly adjustments will average between 15 and 30 euros for the majority of affected residents, according to Ingo Malter, chief executive of Stadt und Land and spokesperson for the seven municipal landlords. For smaller apartments, increases start at a few cents per month, whereas select units larger than 100 square meters face monthly hikes exceeding 100 euros. Stadt und Land reports an average in-place net cold rent of 7.31 euros per square meter, with the broader municipal portfolio maintaining comparable levels. Across all member companies of the BBU housing association, average rents stood at 7.18 euros per square meter net cold at the end of 2025.

Senate agreements and rent index integration

The municipal enterprises operate under a formal cooperation agreement with the Berlin Senate that imposes tighter caps than those governing the private rental sector. Under these guidelines, an enterprise may raise its total portfolio rent by no more than an average of 2.9% annually, while individual tenancy increases cannot exceed 11% over a three-year period. Across the private Berlin rental market, landlords may increase rents by up to 15% every three years up to local comparative rates. The state companies also include an affordability commitment stipulating that net cold rent should not exceed 27% of household income, though Malter noted that few tenants have invoked this provision in practice. Malter explained that the timing of the mailings followed the publication of Berlin's updated rent index in June 2026, which recorded a 7% average increase in local comparative rents since 2024 and required administrative integration into enterprise IT systems.

Political dispute following the state election

The arrival of the adjustment notices came shortly after the Berlin Abgeordnetenhaus election on 20 September 2026, in which Die Linke emerged as the largest political force. Housing policy stood as the central pillar of the party's platform, which campaigned on capping municipal rents and socializing large corporate housing portfolios. Niklas Schenker, tenancy policy spokesperson for Die Linke in the Abgeordnetenhaus, criticized the timing as an effort by municipal managers to preempt forthcoming policy changes before a coalition government takes office.

The impression forces itself upon me that the enterprises wanted to raise rents once again before a new government imposes a rent freeze.

Reactions from tenant advocates and housing management

The Berlin Tenants' Association (Berliner Mieterverein) joined calls for the municipal landlords to withdraw the notices, identifying this round as the fourth broad wave of rent increases within three years. Managing director Sebastian Bartels argued that issuing increases immediately after polling stations closed challenged the democratic decision of voters. Malter rejected allegations of political timing at a BBU press conference on 30 September 2026, stating that rate adjustments proceed independently of political campaigns. He cited rising construction and maintenance expenses recorded between 2016 and 2025 to justify the revenue needs of the landlords. Malter warned that reversing the executed rent increases would stall essential building investments and impair a substantial portion of Berlin's economic strength.

We need the foundation for necessary investments.
