What the rent cap means in Berlin

The rent cap limits how high net cold rent may be at the start of a tenancy: usually the local comparative rent plus 10 percent. In Berlin the benchmark is the qualified 2026 rent index.

Whether that is unlawful in your case depends on the contract: start date, previous rent, modernisation, furnishing and statutory exceptions.

Frequently asked questions

Does the rent cap still apply in Berlin in 2026?
Yes. Berlin is a designated tight housing market. Whether it applies to your contract depends on the start date (from 1 June 2015), exceptions such as new builds, and the details of the tenancy agreement.
How do I tell if my rent is too high?
Orientation comes from the qualified Berlin rent index 2026 plus 10%. Our rent calculator shows that range. Whether you have a claim still depends on the previous rent and the contract.
Can I recover overpaid rent?
If the rent cap applies, rent above the cap can often be reclaimed for a limited period. That needs a case-by-case legal review — not a calculator result.
What does the first assessment cost?
The initial review is free and without obligation. You only instruct us if you want us to proceed.
