The default statutory rule of the German Civil Code (BGB § 535) states that the landlord is responsible for maintaining and repairing the leased property. However, in commercial tenancy law, this principle is almost always completely reversed by the lease agreement. Commercial landlords in Schleswig-Holstein have vast leeway to shift maintenance obligations and costs onto the tenant.

Transferring Maintenance Duties

Unlike residential leases, where shifting large repair costs is prohibited, commercial leases often employ mechanisms to minimize the landlord's operational expenditures (OpEx):

1. "Dach und Fach" (Roof and Structure) Clauses

A prevalent standard in German commercial leases is to split maintenance responsibilities:

  • Tenant: Assumes the maintenance and repair of the interior of the rented space, including technical installations (electric, plumbing, HVAC specific to the unit), doors, interior windows, and cosmetic repairs.
  • Landlord: Maintains responsibility for "Dach und Fach"—the overarching building envelope (roof, facade, load-bearing walls) and central building systems serving all tenants (e.g., central heating plant, main electrical feeds, elevators).

2. Triple-Net-Lease (NNN)

Common in standalone commercial buildings (e.g., entire logistics centers, retail supermarkets):

  • The tenant essentially bears all costs related to the property.
  • This includes property taxes (Net 1), building insurance (Net 2), and all maintenance, repairs, and capital expenditures (CapEx) for the building structure and roof (Net 3).
  • Warning regarding AGB Law: If the lease is a pre-formulated standard contract (AGB), shifting the risk for the building structure (roof and framework) entirely onto the tenant may be deemed legally invalid, as the tenant cannot calculate the unpredictable risk of structural failure. Such a shift must be genuinely and individually negotiated between the parties (Individualvereinbarung).

Maintenance Caps and Cost Sharing

Where costs for maintaining common systems (like a shopping mall elevator or HVAC system) are passed through operating cost allocations to various tenants, landlords must be mindful of AGB regulations:

  • If maintenance and repair costs for common systems are allocated to tenants via pre-formulated standard terms, the Federal Court of Justice (BGH) requires a cost cap (e.g., "max. 6% of the annual net rent") to prevent the tenant from bearing an unkalkulable financial burden.
  • Without a cap, the entire maintenance transfer clause may be voided, forcing the landlord to pay 100% of the costs.

Non-Transferable Landlord Duties

Even in a commercial "Triple-Net" scenario in Schleswig-Holstein, the landlord cannot fully absolve themselves of specific overarching responsibilities:

1. Duty to Maintain Safety (Verkehrssicherungspflicht)

As the property owner, the landlord bears the residual responsibility to ensure the property poses no danger to the public or the tenant's employees/customers.

  • Winter Services: While snow clearing can be outsourced to the tenant or a facility management company (crucial in coastal SH regions prone to black ice and sudden snow squalls), the landlord retains a duty of supervision (Überwachungspflicht).
  • Facade Safety: Ensuring roof tiles, signs, or facade elements are secure against heavy northern German storms.

2. Regulatory Compliance

If new building regulations or environmental laws (e.g., new fire safety codes, mandatory energy efficiency upgrades under the GEG) demand structural alterations, the landlord is generally responsible for addressing them—unless the necessity for the upgrade arises exclusively from the tenant's specific type of commercial use.

Defects and Rent Reduction (Mietminderung)

If a defect occurs that the landlord is responsible for repairing (e.g., a leaking roof under a "Dach und Fach" agreement):

  • The commercial tenant has the right to reduce the rent (BGB § 536).
  • However, commercial contracts almost always contain a valid clause restricting this right: The tenant must continue paying the full rent and instead pursue a separate claim for a refund (Rückforderungsanspruch) due to unjust enrichment later. This ensures the landlord's cash flow is not suddenly interrupted while a defect's root cause is being investigated.

Tips for Landlords

  • Avoid Standard AGB Traps: Be exceedingly precise when delineating maintenance duties. Ensure any complete structural risk transfers (Triple-Net) are verifiably negotiated individually, not just checked off on a standard form.
  • Establish Maintenance Cycles: Require the tenant to conclude long-term maintenance contracts with certified specialty firms for HVAC and fire safety systems, and mandate that proof be sent to the landlord annually.
  • Implement Rent Reduction Waivers: Always include standard commercial clauses that prohibit unauthorized rent retention or offsetting against the rent due to alleged defects.
  • Regular Inspections: Contractually secure your right to inspect the commercial premises regularly to verify the tenant is upholding their maintenance duties, preventing long-term dilapidation of your asset.
