Commercial Tenancy Law in Schleswig-Holstein: A Guide for Landlords

Unlike the strictly regulated residential tenancy law designed to protect tenants, commercial tenancy law (Gewerbemietrecht) in Schleswig-Holstein—and throughout Germany—is characterized by extensive freedom of contract (Vertragsfreiheit). The law assumes that commercial lease agreements are negotiated between two equal business partners. Landlords of offices, retail spaces, warehouses, or medical practices in Kiel, Lübeck, Flensburg, or the economic hubs along the A1 autobahn thus enjoy considerable leeway in structuring their contracts.

Key Differences to Residential Tenancy Law at a Glance

1. Duration and Termination (Fixed-Term Leases)

Unlike residential spaces, commercial leases can be concluded for a fixed term without providing material reasons. This is, in fact, the standard practice to secure investments for both parties:

• Leases are often signed for fixed terms of 5 or 10 years.
• An ordinary termination is then excluded for both parties during this period.
• Extension options (Verlängerungsoptionen) are popular, allowing the tenant to unilaterally declare they wish to extend the contract (e.g., for another 5 years) after the initial term ends.

For indefinite contracts, a statutory ordinary notice period applies under BGB § 580a para. 2: roughly 6 months, taking effect at the end of the next calendar quarter if notice is given by the third working day of a quarter. However, this is frequently altered in the contract.

2. Maintenance and Operating Costs

Commercial tenancy law grants significant flexibility here as well:

• It is permissible to transfer almost all maintenance and repair costs of the leased property to the commercial tenant via the contract (so-called "roof and structure" clauses or "Triple-Net-Lease" models).
• All operating costs (including property management fees and specific insurances), which could not be apportioned in residential law, may be passed on to the commercial tenant—provided the contract explicitly states this.

3. Rent Amount, Rent Increases, and Security Deposits

The initial rent and rent adjustments for commercial spaces are not subject to state caps such as the residential rent cap (Kappungsgrenze).

• Security Deposits can be freely negotiated. While bank guarantees are common, the landlord is not obligated to invest the deposit in an insolvency-proof and interest-bearing manner as they are with residential tenants (unless contractually agreed).
• Rent increases during an ongoing contract do not exist by law as they do for residential properties. Landlords must proactively define rent increases via index contracts (linked to the Consumer Price Index), step rents, or turnover clauses.

4. Protection Against Competition (Konkurrenzschutz)

An inherent protection in commercial tenancy law—which does not need to be explicitly written in the contract (excluding it is risky for landlords)—is contractual protection against competition. A landlord may not rent out spaces in the same or adjacent building to an enterprise that would be in direct competition with their existing tenant (e.g., two bakeries under one roof), as this would disturb the tenant's contractual use of the leased property.

5. Strict Written Form Requirement (Schriftform)

BGB § 550 also applies rigorously to commercial properties: Contracts running for longer than one year must be drawn up in writing (with original signatures on the same document by all contracting parties). If any part of the complex commercial lease or its often numerous annexes violates this written form clause, the entire fixed-term contract suddenly becomes legally "concluded for an indefinite period." This abruptly eliminates any long-term mutual commitment, and the property can suddenly be terminated with statutory notice (approx. 6 months) under BGB § 580a ("Written Form Termination"). This presents a massive valuation risk for investment assets.
