The security deposit (Mietkaution or Mietsicherheit) protects landlords in Schleswig-Holstein against financial claims arising from the tenancy, such as unpaid rent or damages to the apartment. The nationwide regulations of the German Civil Code (BGB), which first became effective on 1 January 1900, apply here, as Schleswig-Holstein has no deviating state-specific rules for security deposits. Legal disputes regarding residential deposits are typically handled by the local court (Amtsgericht) in whose district the property is situated.
Maximum Deposit Amount
According to BGB § 551, the security deposit for residential space may not exceed three months of net cold rent (Nettokaltmiete)
The calculation is based on the initial net cold rent at the start of the tenancy. Operating costs, utility prepayments, and flat-rate accessory charges are not included in this calculation.
Right to Pay in Installments
The tenant has a statutory right to pay the security deposit in three equal monthly installments: * The first installment is due at the start of the lease (not at the time the contract is signed). * The other two installments are due together with the immediately following rent payments. * This rule is mandatory and cannot be contractually altered to the detriment of the tenant (BGB § 551 para. 4).
Requirement for Insolvency-Proof Investment
The landlord is not permitted to simply hold the security deposit in their standard checking account:
- Separation of Assets: The deposit must be kept strictly separate from the landlord's private or business assets to protect the funds in the event of the landlord's insolvency.
- Account Type: It is standard practice to place the funds in a savings account with a three-month notice period (often called a rent deposit account or trust account).
- Interest: Any interest generated belongs to the tenant and continuously increases the deposit amount.
Alternatively, the deposit can be provided as a bank guarantee (Bankbürgschaft) or deposit insurance (Kautionsversicherung), provided the landlord agrees to this form.
Returning the Security Deposit
Unlike some jurisdictions, German law does not set a strict, statutory deadline (such as exactly 14 or 21 days) for returning the deposit
Courts grant landlords a reasonable period for consideration and review:
Landlords may withhold a reasonable portion of the deposit if an annual utility bill is still pending and a supplementary payment from the tenant is expected.
Permissible Deductions
At the end of the tenancy, the landlord may offset the deposit against outstanding claims, including:
- Rent arrears or unpaid utility bill balances
- Compensation for damages to the apartment that exceed normal wear and tear
- Costs for omitted cosmetic repairs (if these were legally transferred to the tenant in the contract)
- Moving-out cleaning costs, if contractually agreed
Important: The landlord's claims for compensation for damages expire according to BGB § 548 after six months from the return of the apartment. Offsetting the deposit is only possible after this period if the right to offset existed before the statute of limitations expired.
Tips for Landlords in Schleswig-Holstein * **Handover Protocol:
** A precise move-in and move-out protocol (Übergabeprotokoll) is the best way to prevent later disputes about damages and deposit deductions. * Take Photos: Always document damages visually and legally note them in the protocol, which both parties should sign. * Prompt Settlement: Even though the law grants 3 to 6 months, it is advisable to process the deposit accounting as quickly as possible to avoid unnecessary conflicts. * Provide Proof of Account: Keep documents proving the proper investment of the deposit to fulfill your obligation to provide evidence to the tenant upon request
