Renting in Germany: deposit, Nebenkosten and moving out

The deposit (Kaution) is usually up to three months of cold rent (Kaltmiete). The landlord must hold it separately from their own money and return it after you move out, minus any justified deductions.

It is not a fee you lose by default. It is your money, held as security.

The landlord can take a reasonable time to return it, often a few months, partly to wait for the final utility statement.

Deductions must be justified with evidence. If the landlord keeps it too long or without reasons, you can demand it in writing and set a clear deadline.

Only for genuine, documented reasons, such as unpaid rent or damage beyond normal use. Normal wear and tear is not chargeable, and a blanket demand for renovation is often not valid.

Ask for an itemised breakdown, and do not accept vague claims. Charges well above the deposit need clear proof.

Nebenkosten are running costs, such as heating, water, and building services, that you pay each month as an advance (Vorauszahlung).

Once a year the landlord sends a statement (Nebenkostenabrechnung) comparing your advances to the actual costs. You either get money back or owe a back-payment (Nachzahlung).

Large back-payments happen, but you can check the statement rather than just paying. You have the right to see the underlying bills and meter readings.

Look at the period covered, your share, and how the costs were split. You generally have time to object in writing if the figures look wrong, so ask for the details before paying a surprising amount.

The Übergabeprotokoll is the handover record made when you move in or out. It lists the condition of the flat and the meter readings, and it is your main protection against later damage claims.

Insist on one, take dated photos, and keep your copy. If the landlord did not make one when you left, note that in writing.

A signed rental contract (Mietvertrag) is binding from the moment both sides sign it, even before you get the keys. A landlord cannot back out just because they changed their mind or found someone who will pay more. Here is what to do:

• First, check your contract for any agreed withdrawal right (Rücktrittsrecht) or condition, for example one that makes it depend on a SCHUFA check. Only such a clause, or a narrow legal ground, lets a landlord get out.
• Insist in writing on the agreed handover date. Set a clear deadline and send it so you can prove it arrived (email plus a registered letter, Einschreiben). This is the record you will need later.
• If they still refuse, you can claim damages (Schadensersatz, § 280 BGB) for the extra costs their breach causes you, such as temporary accommodation, storage, moving costs, and the difference if a replacement flat is more expensive. Keep every receipt.
• If you want that specific flat, you can also demand handover, and in urgent cases apply for an interim injunction (einstweilige Verfügung), though courts grant this only in clear cases.
• Get support quickly from a local tenants' association (Mieterverein) or a lawyer for tenancy law (Mietrecht). Legal insurance (Rechtsschutzversicherung) can cover it if you held the policy before the dispute began.

A local tenants' association (Mieterverein) gives advice for a modest membership fee and is widely used. Legal insurance (Rechtsschutzversicherung) can cover disputes if you had it before the problem started.

For a deposit that is wrongly withheld, a formal written demand with a deadline often resolves it before anyone goes to court.
