Commercial Maintenance Obligations in Berlin: Roof & Structure, Repairs

Unlike residential tenancy—where the landlord heavily bears the burden of maintenance—commercial tenancy law allows landlords to significantly shift the financial responsibility for maintenance and repairs to the tenant. However, there are strict limits regarding standard lease templates.

The Statutory Default: Landlord Pays

According to the German Civil Code (BGB § 535), the default legal position is identical to residential law: The landlord must maintain the property in the contractually agreed condition.

If the commercial lease does not mention maintenance at all, the landlord pays for everything—from changing lightbulbs to replacing the HVAC system. Therefore, shifting this burden via the lease agreement is the most critical aspect of commercial property management.

Shifting the Burden: What is Permitted?

The method of concluding the lease dictates how much maintenance can be transferred:

1. Standard Template Contracts (AGB)

Most leases are pre-formulated templates (Allgemeine Geschäftsbedingungen - AGB). German courts aggressively police these to protect tenants from "unreasonable disadvantage," even in B2B contracts.

In standard AGB leases, the landlord CANNOT transfer:

• "Roof and Structure" (Dach und Fach): The exterior shell, load-bearing walls, roof, and foundation.
• Initial defects: Issues that existed before the tenant moved in.
• Repairs to crucial communal technical systems: E.g., replacing the central building heating plant or massive communal ventilation systems. (Routine maintenance of these is okay; replacement is not).

If a landlord includes a template clause forcing the tenant to "pay for all repairs to the roof," the German Federal Court of Justice (BGH) considers the clause entirely void, meaning the landlord must suddenly pay for all interior and exterior repairs.

2. Individually Negotiated Contracts (Individualvertrag)

If a clause is genuinely, individually negotiated (e.g., the tenant accepts full responsibility for the roof in exchange for a massive 30% discount on the market rent), then almost any transfer of duties is legally valid. This is how Triple-Net (NNN) leases are structured in Germany. Proving a clause was individually negotiated requires extensive documentation.

The Standard Distribution in Berlin

A legally robust standard commercial lease in Berlin generally distributes duties as follows:

Landlord's Responsibility

• Roof, facade, windows (exterior).
• Load-bearing structures.
• Replacement of communal technical facilities (elevators, central heating).
• Compliance with public safety laws (e.g., fire safety) affecting the whole building.

Commercial Tenant's Responsibility

• Interior Maintenance: floors, interior painting, interior non-load-bearing walls.
• Interior Repairs: Replacing broken sanitary fixtures, interior doors.
• Cosmetic Repairs (Schönheitsreparaturen): Full responsibility to renovate the interior at appropriate intervals.
• Maintenance Contracts: The tenant is obliged to conclude and pay for service contracts for directly used technical equipment (e.g., their own AC units, roll-up gates).

The Crucial Cost Cap (Kostenkappungsgrenze)

If a landlord uses an AGB template to transfer the cost of maintaining communal facilities (like the central HVAC, elevators, or shared sprinkler systems) to the tenant as an operating cost, it must contain a hard financial cap.

• The Rule: Without an upper limit (e.g., "Max. 6% of the annual net rent per year for maintenance of communal facilities"), the transfer is legally void.
• The Result: The landlord must pay the entire maintenance bill.

Reinstatement and Removal (Rückbau)

At the end of a commercial lease, disputes frequently arise over the condition of the property.

• The General Law: The commercial tenant must remove all their installations, fixtures, and alterations, restoring the space to its original condition (Rückbaupflicht).
• Exceptions: If the landlord explicitly and unconditionally approved an alteration without a reservation to demand removal, the tenant might not have to remove it.
• Best Practice: The landlord should meticulously document the original state with an extensive handover protocol and photos. Contracts should explicitly state that all tenant alterations must be removed upon exit unless the landlord demands they stay.

New Energy Efficiency Duties (GEG) - 2024/2025

The revised Building Energy Act (GEG) imposes sweeping duties on owners of non-residential buildings:

• Heating Inspections: Heating systems in larger commercial buildings must undergo specific efficiency checks.
• Building Automation: By the end of 2024 (and continuing into stricter 2025 standards), large non-residential buildings (with AC/heating systems over 290 kW output) must be equipped with digital building automation and control systems.
• Who Pays? These are capital expenditures (CapEx) resting firmly on the building owner. Attempting to classify the mandatory installation of a building automation system as an operating cost (OpEx) for the commercial tenant is generally invalid in AGB leases.

Best Practices for Commercial Landlords

1. Avoid "Dach und Fach" in Templates: Do not use boilerplate lease templates that try to make a small retail tenant responsible for the building's roof. It will render all maintenance clauses void.
2. Cap Shared Maintenance: Always include a percentage cap (e.g., 6-8% of annual rent) when passing on the repair costs of shared technical systems.
3. Mandate Maintenance Contracts: Require the tenant to sign professional maintenance contracts for specialized equipment (e.g., grease traps in restaurants, high-voltage systems) and submit proof of these contracts annually.
4. Document "Individual Negotiation": If you agree on a true Triple-Net lease, retain all negotiation emails, draft markups, and correspondence proving that the tenant received a benefit (like lower rent) in exchange for assuming the structural risks.

How Landager Helps

Landager’s maintenance module allows commercial landlords to track which tenant is responsible for which system. You can set automated reminders to ensure tenants submit proof of their required annual maintenance contracts (e.g., for safety doors or HVAC), shielding you from liability.
