The security deposit (Mietkaution) protects landlords against financial losses if a tenant fails to meet their contractual obligations. In Baden-Württemberg, as throughout Germany, the rules governing residential security deposits are strictly defined by the German Civil Code (Bürgerliches Gesetzbuch – BGB), specifically § 551 BGB, which was introduced in its current form in 2001 (preceded by § 550b in 1982).

Maximum Deposit Amount
Under § 551 (1) BGB, the security deposit for residential tenancies is legally capped:
- Maximum 3 months' net cold rent (Nettokaltmiete): The deposit may not exceed three times the monthly rent. Utility prepayments (Vorauszahlungen) and flat-rate utility charges (Pauschalen) must be excluded from this calculation.
- Any contractual agreement for a higher deposit is void.
- The tenant has the statutory right to pay the deposit in three equal monthly installments (§ 551 (2) BGB). The first installment is due at the start of the tenancy; the subsequent two are due with the following two rent payments.
Mandatory Insolvency-Proof Investment
The landlord cannot simply keep the deposit in their personal bank account or use it for their own purposes:
- Separation from personal assets: The deposit must be kept strictly separate from the landlord's own funds.
- Dedicated deposit account: Typically, a special savings account (Kautionskonto) is opened at a bank.
- Interest: The deposit must be invested at the prevailing rate for savings deposits with a three-month notice period. Interest earned increases the deposit and is owed to the tenant at the end of the tenancy.
Exception: Student or youth dormitories are exempt from interest obligations (§ 551 (3) sentence 5 BGB).
Permitted Deductions
At the end of the tenancy, the landlord may deduct from the deposit for legitimate claims against the tenant:
- Outstanding rent or unpaid utility charges
- Costs for unreturned cosmetic repairs (if validly agreed in the lease)
- Damages beyond normal wear and tear caused by the tenant
What Cannot Be Deducted
- Normal wear and tear — e.g., carpet wear from regular use, faded wall paint after several years
- Pre-existing damage — conditions documented in the move-in inspection report
- Repairs the landlord is responsible for — e.g., heating system failures, plumbing issues in walls
Return Timeline
While no fixed statutory deadline exists, landlords are granted a reasonable review and consideration period (typically 3 to 6 months) to inspect the property:
- Inspection Period: During this time, the landlord may check for hidden damage and await any outstanding utility bills.
- Partial retention for utilities: If a utility bill (Betriebskostenabrechnung) is still pending, the landlord may only retain a 'reasonable portion' (angemessener Teil) of the deposit if a back-payment is specifically expected based on prior consumption patterns (BGH VIII ZR 71/05).
Once all claims are resolved, the deposit plus accrued interest must be returned to the tenant without undue delay.
The Move-In/Move-Out Inspection Report
While not legally mandatory, a move-in/move-out inspection report (Übergabeprotokoll) is the single most tool for preventing deposit disputes. The report documents the condition of the unit, meter readings, and any existing defects — providing legally defensible evidence for both parties.
Disputes and Jurisdiction
In the event of a dispute regarding the security deposit or its return, the local District Court (Amtsgericht) where the property is located has exclusive jurisdiction regardless of the amount in controversy (§ 23 Nr. 2a GVG; § 29a ZPO).
Best Practices for Landlords
- Photograph everything at move-in and move-out — Date-stamped visual records are invaluable in disputes.
- Use a structured checklist — Have the tenant sign the protocol at both move-in and move-out.
- Open a dedicated Kautionskonto — It's the law, and failing to do so can expose you to liability.
- Don't wait the full 6 months — Prompt returns build trust and reduce legal exposure.
- Document every deduction — Attach invoices and photos for any amount withheld.
