Orientation based on the qualified Berlin rent index 2026: as a rule, rent may be at most 10 % above the local comparative rent (section 556d BGB).
When the rent cap applies – and when it does not
- It applies throughout Berlin (rent cap ordinance of 11 Nov 2025, in force 1 Jan 2026 – 31 Dec 2029).
- Not for first use/first letting after 1 Oct 2014 (section 556f sentence 1 BGB).
- Not for the first letting after comprehensive modernisation (section 556f sentence 2 BGB).
- Contracts starting before 1 June 2015 are not covered by the cap.
- A higher previous rent can affect the permitted rent (section 556e BGB).

Current cases from our firm
Rent reduced from €1,200 to €750, €900 repaid, €2,070 deposit released
„A few weeks after our objection: net cold rent €750 instead of about €1,200, €900 repaid and €2,070 of the deposit released — furnished sublet, out of court, no assignment.“
Rent reduced from €723 to €690, €779 repaid
„The modernisation exception failed on form: no text-form notice before the contract. Within a few weeks the rent falls retrospectively to €689.63 — €779 was paid in full to the tenant.“
€1,460 → €595 claimed, ~€10,810 repayment (pending)
„About 70 m² in a simple location: €20.86/m² instead of a likely permitted €595. The objection is within the 30-month window — proceedings are pending.“
