Received a rent increase? How to check whether it is permissible

Your landlord demands a higher rent? Not every rent increase is effective. It must be justified, keep within limits, and you must actively agree to it. It is worth checking closely before you sign.

Check the rent increase

Your chances of getting your money back

An increase up to the local comparable rent must be justified (rent index, comparable apartments, § 558 BGB) and, within 3 years, must not exceed the capping limit of 20% (15% in strained markets).
You have a period for consideration and must agree to the increase. Without your consent the landlord can only enforce it through the court; formal errors make it ineffective.

What you should do now

  1. 1

    1. Check the justification

    Is the increase justified with a rent index, comparable apartments or an expert report? Without a proper justification it is ineffective.

  2. 2

    2. Check the limits

    Is the new rent above the local comparable rent or above the capping limit? Then it is (partly) impermissible.

  3. 3

    3. Use the consideration period

    You have until the end of the second month after receipt to react. Do not agree hastily.

  4. 4

    4. Agree partially

    If only part of the increase is justified, you can agree to only that part.

Frequently asked questions

Do I have to agree to a rent increase?

For an increase to the local comparable rent, your consent is needed; the landlord can otherwise only enforce it in court. For modernization or index rent increases, separate rules apply. Check the justification and limits carefully.

What is the capping limit?

Within 3 years the rent (up to the comparable rent) may rise by at most 20%, and in areas with a strained housing market by only 15%. Increases beyond that are impermissible.
