Default and Late Fees in Berlin Commercial Leases: Interest Rates & Eviction

Unlike residential tenancy, where the law heavily protects consumer tenants from late fees and sudden evictions, commercial leasing operates under B2B (Business-to-Business) rules. In Berlin, commercial landlords possess sharp legal tools to penalize late rent and immediately terminate leases for non-payment.

Higher Default Interest Rates (Verzugszinsen)

Because commercial leases are transactions between businesses (Unternehmer), the statutory penalties are significantly harsher.

The Commercial Rate

Under BGB § 288 (2), the default interest rate for commercial transactions is 9 percentage points above the Bundesbank Base Rate (Basiszinssatz). (By comparison, residential landlords can only charge 5 points above the Base Rate).

Calculation Example

If the German Base Rate is set at 3.62%:

• Default Interest Rate: 3.62% + 9% = 12.62% per annum.
• If a commercial tenant owes €10,000 for one month, the default interest is €105.17 for that month alone.

Automatic Default

Rent is typically due by the third business day of the month (§ 556b BGB). If the money is not in the landlord's account by then, the tenant is automatically in default (Verzug). No initial warning letter (Mahnung) is required to trigger the high interest rate.

The Statutory €40 Flat Fee

A unique and highly effective tool for commercial landlords:

According to BGB § 288 (5), in B2B transactions, the creditor has an automatic statutory right to a €40 flat-rate fee (Mahnpauschale) the moment the debtor falls into default.

• No proof required: You do not need to prove you suffered €40 in administrative damages.
• Cumulative: The €40 is owed in addition to the 9% default interest.
• Contractual superiority: This right cannot be waived or lowered in standard AGB contract terms.

Contractual Penalties (Vertragsstrafen)

While arbitrary late fees are illegal in residential law, commercial landlords have more freedom to incorporate warning fees and contractual penalties into the lease.

• Warning Fees: Charging €5.00 to €10.00 for a second or third written warning is generally accepted as standard business practice.
• Contractual Penalties: You can stipulate specific financial penalties for breaches other than late rent (e.g., a €500 fine per day for failing to open a retail store during core mall hours, violating the "Operating Duty").
• AGB Limits: Even in commercial law, penalties in pre-formulated templates must not be "unreasonably disproportionate." A penalty exceeding 1-2% of the monthly rent per week of delay is highly vulnerable to being struck down by a court.

Immediate Termination for Rent Arrears

If the commercial tenant persistently fails to pay, the landlord can execute the "nuclear option": Immediate Extraordinary Termination (Fristlose Kündigung).

The Grounds (BGB § 543)

The landlord can immediately terminate the lease if:

1. The tenant is in default for two consecutive dates with a significant portion of the rent.
2. Over a longer, non-consecutive period, the accumulated unpaid rent exactly equals the sum of two full months' rent.

The Massive Commercial Advantage: No Grace Period Healing

In residential law, a tenant who receives an immediate termination and an eviction lawsuit can simply pay the debt within two months—making the termination retroactively invalid (Schonfristzahlung).

This does not exist in commercial tenancy law.

• Once a commercial landlord legally issues an immediate termination due to the required rent arrears, the contract is dead.
• If the tenant wires the €30,000 debt the very next morning, the landlord keeps the money to clear the debt, but the eviction still stands. The landlord is not forced to continue the lease.

The Landlord's Lien (Vermieterpfandrecht)

To secure unpaid rent and late fees, commercial landlords have a powerful statutory tool: the Landlord’s Lien (BGB § 562).

• The landlord has a lien on all items the tenant has brought into the leased premises (inventory, machinery, office equipment).
• The landlord is legally allowed to prevent the tenant from removing these items if they are in default.
• In severe cases (and strictly following legal procedures), the landlord can seize the items and auction them off to satisfy the rent debt. This is exceptionally effective in the restaurant or manufacturing industries where heavy equipment is vital to the tenant's business.

Best Practices for Commercial Landlords

1. Enforce the Rules Immediately: Commercial tenants often prioritize other creditors if they know the landlord is lenient. Charge the 9% interest and the €40 statutory fee from day one.
2. Issue the Immediate Termination Fast: As soon as the two-month threshold is breached, serve the immediate termination heavily documented via a bailiff. You dictate the terms from that point on.
3. Use the Lien: If a tenant is failing, immediately assert your Vermieterpfandrecht in writing to prevent them from staging a "midnight flit" and emptying the warehouse.
4. Demand Bank Guarantees: Ensure your security deposit is an "on-first-demand" bank guarantee, providing you instant liquidity when rent goes unpaid.

How Landager Helps

Landager’s commercial engine automatically calculates the B2B 9% default interest based on the fluctuating Base Rate. The system flags accounts falling into default, applies the statutory €40 fee automatically, and alerts you the exact day the "two-months arrears" threshold is crossed for immediate eviction.
