Commercial Security Deposits in Schleswig-Holstein: Rules for Landlords

In commercial tenancy law in Schleswig-Holstein, entirely different rules apply to the security deposit (Mietsicherheit) than in residential tenancy law. The strict upper limit of three net cold months' rent imposed by BGB § 551 does not apply to commercial leases.

Free Negotiability of the Deposit Amount

In practice, landlords of commercial properties in Schleswig-Holstein usually demand three to six gross monthly rents as a security deposit, reflecting the higher risks and potential costs of property restoration.

Forms of Commercial Security Deposits

1. Cash Deposit (Barkaution)

The tenant deposits the agreed amount in cash or via bank transfer. Unlike residential spaces, the landlord is not obligated to invest the deposit in a separate, interest-bearing account, unless the contract specifically dictates otherwise.

2. Bank Guarantee (Bankbürgschaft / Avalbürgschaft)

The most common form in the commercial sector. The tenant's main bank issues a directly enforceable guarantee. Advantages:

• The tenant retains their liquidity.
• The landlord receives a direct payment commitment from the bank.
• On first demand guarantees (Bürgschaften auf erstes Anfordern) are customary, allowing the landlord swift access to funds without prior court proceedings.

3. Deposit Insurance (Kautionsversicherung)

For an annual premium (usually 3–5% of the deposit sum), an insurance company assumes the guarantee. This variant is increasingly utilized but is not accepted by all landlords.

4. Corporate Guarantee (Konzernbürgschaft)

For tenants who are part of a larger corporate group, the parent company can assume a guarantee. The creditworthiness of the guarantor is the decisive factor here.

Repayment of the Commercial Deposit

Unlike residential tenancy law, there is no typical judicial practice regarding repayment deadlines:

• The deadline is primarily determined by the contractual agreement.
• If an agreement is absent, the deposit must be returned within a reasonable period after the end of the tenancy and the clarification of all claims.
• Because commercial accountings are often complex (final utility bill reconciliations can take several months), deadlines of 6 to 12 months are not uncommon.

Permissible Deductions

The landlord may offset the commercial deposit against:

• Rent arrears and outstanding utility bill supplementary payments
• Compensation for damages to the leased premises
• Deconstruction costs (Rückbaukosten), if the tenant was obligated to restore the property to its original condition but failed to do so
• Outstanding claims from contractual duties (e.g., missed maintenance services)

Tips for Landlords

• Assess Deposit Pragmatically: Base the amount on the fit-out standard and the investment risk of the specific commercial unit.
• Prefer 'On First Demand': A bank guarantee "on first demand" accelerates access in the event of a claim and bypasses drawn-out disputes.
• Avoid Expiry Dates: Ensure bank guarantees do not have a hard expiration date, as limited guarantees simply lapse.
• Define Repayment Terms: Clearly define the repayment deadline and the accounting procedure in the lease contract.
