Key takeaways
- The deposit (Kaution) cannot exceed three months' net cold rent under § 551 BGB. For furnished mid-term rentals it is typically 1–2 months' all-inclusive rent.
- Landlords must hold the deposit in a separate account. They cannot use the funds during the tenancy.
- Always complete a signed handover protocol (Ãœbergabeprotokoll) at move-in and move-out, with photos. This is your strongest protection against unjustified deductions.
- Normal wear and tear cannot be deducted. Deductions are only valid for documented damage beyond ordinary use.
- Landlords generally have 3–6 months to return the deposit. After six months without justification, their right to make deductions typically lapses.
What is the apartment deposit?
The apartment deposit, also known as a security deposit or rent deposit, is a payment that tenants make to landlords before moving in. It is a form of financial protection for landlords in case tenants fail to honour their rental agreements — such as not paying rent or causing property damage. In Germany, the term Kaution (or Mietkaution) is used.
The Kaution is regulated by § 551 of the Bürgerliches Gesetzbuch (BGB). The law sets a ceiling on the amount, specifies how it must be held, and protects tenants from having it used during the tenancy. Understanding these rules before you pay is the best way to ensure a smooth recovery at the end of your lease.
How much is the deposit?
The amount of the security deposit is regulated by German law and cannot exceed three months' net cold rent (§ 551 BGB). Net cold rent means the base rent excluding utilities, service charges, and other additional costs.
For furnished mid-term rentals — such as those offered through Wunderflats — all-inclusive rents cover utilities and a furnishing surcharge. The deposit may be higher than for unfurnished apartments, since it also covers the potential cost of replacing or repairing damaged furniture and appliances. In this case, the deposit is typically between one and two months' all-inclusive rent.
| Rental type | Deposit basis | Typical range |
|---|---|---|
| Unfurnished long-term | Net cold rent (Kaltmiete) | Up to 3 months (legal max) |
| Furnished mid-term (Wunderflats) | All-inclusive rent (includes furnishings cover) | Typically 1–2 months |
How and when to pay
When to pay
As a tenant, you will typically pay the security deposit before the start of the tenancy or by the time you move into the property.
Payment methods
The security deposit is normally paid by bank transfer or cash deposit. However, alternatives exist:
- Guarantee: A person or institution takes on financial responsibility for the tenant up to the deposit amount. No money is transferred to the landlord.
- Security deposit insurance: An insurance company pays the deposit on the tenant's behalf. More common in unlimited rental agreements; mid-term rentals typically stay with cash deposits and bank transfers.
Under § 551 BGB, tenants also have the right to pay the deposit in up to three monthly instalments rather than as a lump sum.
💡 Tip: Always get a written deposit receipt from the landlord as soon as payment is made. The receipt should include the deposit amount, the date paid, and the full names and addresses of both parties. This is your proof of payment if a dispute arises later.
Managing the deposit during the tenancy
German law requires landlords to hold the security deposit in a separate escrow account throughout the rental period — typically a savings account (Sparbuch) — with interest accruing in the tenant's favour. Landlords cannot access or use this money during the tenancy. This protection means the deposit remains available even if the landlord faces financial difficulties.
⚠Warning: The last month's rent cannot be deducted from the deposit. The deposit exists to cover post-tenancy damage and outstanding costs — not rent. As a tenant, you remain responsible for paying rent in full for the entire duration of the rental agreement.
During the tenancy, report any damages or problems to the landlord in writing as soon as they occur. Prompt reporting demonstrates responsible tenancy and ensures necessary repairs are carried out properly — reducing the risk of disputes at move-out.
The handover protocol
The apartment handover protocol (Ãœbergabeprotokoll) is the most important document for protecting your deposit. It records the condition of the property and all its contents at both move-in and move-out.
At move-in, the protocol should document:
- Every item provided by the landlord (furniture, appliances, kitchenware, electronics)
- The condition of each item
- Any pre-existing damage
- Meter readings (electricity, gas, water)
Attach dated photographs and ensure both landlord and tenant sign the document. Keep your copy.
💡 Tip: At move-out, complete the same protocol again. Any differences between move-in and move-out conditions that go beyond normal wear and tear can be subject to deduction — but only if documented. A thorough, signed handover protocol at both ends of the tenancy is your strongest protection against unjustified claims.
It is also important to discuss and agree on a deposit return timeline with the landlord at the beginning of the rental period — so both parties know what to expect at the end.
Getting your deposit back
When is the deposit returned?
The security deposit must be returned by the landlord at the end of the rental period, minus any valid deductions. German courts generally accept three to six months as a reasonable processing window — this allows time to check the property's condition, assess any damage, and reconcile utility bills.
In special situations where operating costs are listed in the contract and final utility statements are delayed, landlords may extend this period to a maximum of 12 months. In this case, they must inform the tenant of the reason for holding the deposit beyond six months.
What can and cannot be deducted
| Valid deductions | NOT valid deductions |
|---|---|
| Documented damage beyond normal use | Normal wear and tear |
| Outstanding rent or utility bills | Minor scuffs or marks from everyday use |
| Repair of broken furniture or appliances (if tenant caused) | Cosmetic repairs where the contract clause is invalid |
| Documented cleaning costs (if property returned in poor condition) | Pre-existing damage recorded in the move-in protocol |
Many cosmetic repair clauses (Schönheitsreparaturen) in standard-form contracts are routinely struck down by German courts as too broad or as imposing rigid renovation schedules regardless of actual wear. If a landlord attempts to deduct for cosmetic work, verify whether the relevant contract clause is actually enforceable.
If the landlord doesn't return the deposit
If the landlord has not returned the deposit within six months and cannot provide a clear explanation for any retention, take the following steps:
- Step 1 — Direct communication: Contact the landlord directly to request the deposit return and a breakdown of any proposed deductions. At Wunderflats, you can also reach out to the Customer Service team for support.
- Step 2 — Written demand: If unresolved, send a formal written demand specifying a minimum two-week deadline for repayment. State that you will seek legal counsel if the deadline is missed.
- Step 3 — Legal assistance: If the landlord still does not comply, contact a Mieterverein (tenants' association) or a qualified Mietrechtsanwalt. Landlords who miss the six-month window generally lose their right to make deductions — the entire deposit may be repayable.
Keep your German bank account open until the deposit is fully returned. If you have moved abroad, ensure the landlord has a reliable postal or bank address to send payment and correspondence.
