Mietpreisbremse Berlin: Current Updates & Impact
The Mietpreisbremse (rent brake) limits how much a landlord can charge on a new lease in Berlin. Since January 1, 2026, it once again applies to the entire city, through December 31, 2029.
How high is the Mietpreisbremse in Berlin?
Under Section 556d BGB, rent on a new lease may not exceed the ortsübliche Vergleichsmiete (local comparative rent), taken from the Berlin Mietspiegel, by more than ten percent. The Senate has designated Berlin as an area with a tight housing market for this purpose, most recently extending it citywide effective January 1, 2026, through December 31, 2029, according to the Senate's press release.
Which leases does the Mietpreisbremse apply to?
It applies to new leases signed since June 1, 2015. Exempt are apartments first ready for occupancy after October 1, 2014, and apartments that underwent a comprehensive modernization under Section 556f BGB. No Mietpreisbremse cap applies to these exceptions, though other rules still apply, such as the modernization rent increase under Section 559 BGB.
What is the rent ceiling in Berlin?
The ceiling is the ortsübliche Vergleichsmiete plus ten percent. If the Mietspiegel puts the comparative rent for an apartment at roughly €10 per square meter, the new rent may not exceed €11 per square meter. The Berliner Mieterverein explains the calculation in detail and offers a Mietcheck tool.
Why the Mietpreisbremse matters for Berlin tenants
Berlin is a rental market where demand clearly outstrips supply. The Mietpreisbremse aims to stop that scarcity from triggering sharp rent jumps every time a tenant changes. It doesn't create additional housing, but it does limit how much rent can rise on a new lease.
What to do if a rent looks too high
If you suspect a violation, start by checking the ortsübliche Vergleichsmiete for your apartment in the Mietspiegel. If the asking rent deviates significantly, you can contact the Berliner Mieterverein or Berlin's rent review office (Mietpreisprüfstelle). If you've already overpaid, a refund may be possible under certain conditions.
Bottom line
The Mietpreisbremse caps rent increases on new leases in Berlin at ten percent above the ortsübliche Vergleichsmiete, and has applied citywide since January 2026 through the end of 2029. Knowing the Mietspiegel lets you judge an offer quickly and seek help from a tenant association if something looks off.
