Mietpreisbremse in Germany: Understanding Rent Control

The Mietpreisbremse is meant to stop landlords from charging whatever they like on a new lease. In practice, many tenants know the rule exists but aren't sure how to check whether it actually applies to a given apartment.

How to check whether the Mietpreisbremse applies to an apartment

First, the municipality needs to be designated as an area with a tight housing market; that's the case in many large German cities, including Berlin and Hamburg, but not everywhere. Check this via your state government's website. If it applies, determine the ortsübliche Vergleichsmiete for a comparable apartment via the local Mietspiegel. Under Section 556d BGB, the new rent may not exceed that figure by more than ten percent.

What legal exceptions exist

Landlords can legally bypass the Mietpreisbremse in certain situations without breaking the law:

New buildings first ready for occupancy after October 1, 2014, aren't subject to any Mietpreisbremse cap.
Comprehensively modernized apartments under Section 556f BGB are likewise exempt.
If the previous rent was already above the allowed limit, the landlord can generally keep charging that previous rent, even if it exceeds the ortsübliche Vergleichsmiete by more than ten percent.

These exceptions are legal; the problem arises only when a landlord falsely claims a modernization or new-build status to sidestep the Mietpreisbremse.

What to do if there's a violation

If you suspect a rent violates the Mietpreisbremse, raise the issue with the landlord in writing. That's a prerequisite for reclaiming any rent overpaid after that point. The Deutscher Mieterbund and local tenant associations can help with the calculation and the wording of such a notice.

Why understanding the Mietpreisbremse helps tenants

Knowing the rules and their exceptions lets you judge more quickly whether an offer during your apartment search is plausible, instead of relying solely on what the landlord tells you. That matters especially in high-demand cities where competition for apartments is fierce.

Bottom line

The Mietpreisbremse caps rent increases on new leases, but only in designated areas, and it has legal exceptions for new builds, modernizations, and already-high previous rents. Checking the Mietspiegel and, if needed, sending a written notice to the landlord are the key steps for tenants.

Frequently Asked Questions

How do I know if an apartment falls under the Mietpreisbremse?

Check whether your municipality is designated as an area with a tight housing market, then compare the asking rent with the ortsübliche Vergleichsmiete in the Mietspiegel.

Are there exceptions to the Mietpreisbremse?

Yes: new buildings first ready for occupancy after October 1, 2014, comprehensively modernized apartments, and cases where the previous rent was already higher.

Can landlords raise the rent after I move in?

Yes, but only under the rules for rent increases during an ongoing tenancy, such as the Kappungsgrenze under Section 558 BGB, not under the Mietpreisbremse.
