Maintenance and Renovation of Commercial Properties in Brandenburg

While in residential tenancy law maintenance is almost exclusively the owner's concern, financial burdens and repair risks in commercial real estate in Brandenburg can be and are massively shifted to the tenant. The exact legal formulation in the contract, however, is critical to success.

The Legal Starting Point

Fundamentally, § 535 of the German Civil Code (BGB) also applies to commercial properties: Unless agreed otherwise in the contract, the landlord is obliged to maintain the building, including the roof, heating, and elevators, at their own expense.

Since this entails incalculable cost risks for commercial owners, the statutory provision is regularly largely derogated (transferred to the tenant) through the principle of freedom of contract.

Roof and Structure (Dach und Fach): What the Landlord Almost Always Bears

The limit of the pre-formulated (formularmäßige) transferability of repair obligations lies in the constitution of the property itself. The obligation to maintain "roof and structure" (Dach und Fach—commercial property tax, exterior walls, foundation, floor ceilings, and load-bearing walls) generally remains inevitably with the landlord.

If a landlord attempts in a standard lease agreement to pass on even the costs for roof repairs to an office tenant through Standard Terms and Conditions (AGB) clauses, the Federal Court of Justice (BGH) assesses this as an unreasonable disadvantage: The entire clause becomes invalid, and the complete maintenance obligation (including for interior walls and floors) falls back on the landlord.

Maintenance Clauses: Single, Double, and Triple Net

To securely delegate repair obligations, nomenclature from the Anglo-Saxon area has become established in the commercial sector, especially for larger properties like logistics parks near Potsdam or Schönefeld:

• Single-Net Lease: In addition to the base rent, the commercial tenant bears the ongoing property taxes (or certain operating costs).
• Double-Net Lease: The tenant bears property taxes, insurance, and the costs for the upkeep and maintenance of the building interior (floors, walls, their own technical facilities). The risk for roof, structure, and central building technology systems (e.g., main heating controller) remains with the landlord.
• Triple-Net Lease: An absolute transfer of almost all obligations. The tenant bears all operating, tax, insurance, and maintenance costs—often also for roof and structure. Attention under German law: This is virtually impossible to agree upon legally securely in pre-formulated contracts (AGB). A Triple-Net arrangement requires a genuine individual agreement, where the tenant has mostly negotiated a measurable counter-performance (e.g., a reduced rent level) in return.

Cosmetic Repairs in Commercial Leases

Just as in residential spaces, cosmetic repairs (Schönheitsreparaturen) in commercial settings can be transferred to the tenant via standard contract clauses, provided no "rigid deadlines" are used.

The special feature in commercial leases: Wear-and-tear-related end-renovation clauses (e.g., "Upon moving out, the walls must be painted regardless of their condition") are partially tolerated by the BGH, provided the tenant took over the property in a renovated state at the start of the contract. However, it is advisable to rely on soft, condition-dependent wording in commercial leases as well, to ensure legal certainty during a judicial review in Brandenburg or at the federal level.

Maintenance of Technical Facilities

Elevators, fire protection dampers, air conditioning units, or roller doors are subject to strict testing deadlines in commercial properties (often to be observed by TÜV or specialist companies).

The landlord should mandatorily ensure in the commercial lease agreement that the tenant bears the costs for these recurring maintenance works of the systems supplying them (often relocatable as utility costs). If the maintenance was fully transferred to the tenant's specialist company, landlords, as owners, often still bear liability externally derived from the duty to maintain safety (Verkehrssicherungspflicht). A proof management system (e.g., annual presentation of maintenance logs by the tenant) is essential.

Maintain Maintenance Management with Landager

The Landager Dashboard helps landlords in Brandenburg to automatically monitor maintenance cycles for commercial technical facilities. Receive timely warnings (e.g., before the expiry of TÜV badges for elevators in office buildings) and manage responsibilities (landlord vs. tenant) legally securely according to the individually stored maintenance clauses of your commercial contracts.
