Information and Disclosure Duties for Commercial Landlords in Rhineland-Palatinate

In contrast to residential leasing, where social legislation demands extreme transparency from the landlord, legislation and jurisdiction in Germany (and thus also in the state of Rhineland-Palatinate) assume fundamentally more experienced, informed market players in the commercial (B2B) sector.

This means the tenant of a commercial property bears a far-reaching duty of inquiry regarding information research and must carry the risk of property usability within strong limits alone. Nevertheless, there are hard boundaries where the landlord possesses mandatory disclosure duties.

Commercial leases are highly complex and almost always deviate from statutory standard regulations. Always consult a licensed attorney in Germany for advice specific to your situation.

1. The Energy Performance Certificate (GEG)

By far the most stringently regulated piece of information for landlords and tenants, which applies unconditionally to almost all commercially marketed commercial properties, is governed by the Building Energy Act (GEG):

• Even in newspaper advertisements or commercial property listings, key figures (such as energy source, building construction year, and final energy demands) must be disclosed mandatorily!
• The landlord is obliged to present the Energy Certificate for Non-Residential Buildings to prospective tenants during an on-site viewing upon request, or display it visibly.
• If the landlord fails to provide this proof on time, it is considered an administrative offense, triggering significant fines in the upper four-digit range upon detection by authorities.

2. Property Use and Building Permits

A major area of conflict in commercial tenancy law is the usability of the space: Who bears the risk of whether a commercial space can be operated, for example, as a hair salon, nightclub, or industrial kitchen (fire safety preparations, official usage permits)?

• Courts generally rule that this operational and utilization risk lies almost entirely with the commercial tenant. The interested party must double-check beforehand (e.g., after viewing) with the building law authorities of the respective Rhineland-Palatinate district administration or independent city (such as Mainz, Koblenz, or Trier) that they are legally allowed to execute their desired purpose in the rental premises.
• The landlord generally has no extensive duty of disclosure here, as they cannot foresee which granular legal restrictions apply to the tenant's business concept.

Limitation (Good Faith) If the landlord positively knows about an existing official usage prohibition for the tenant's intended business type—and conceals this to keep the spaces leasable (Fraudulent Misrepresentation)—this constitutes a gross breach of duty. This grants the tenant the right to immediate termination (often coupled with high damage claims from the business owner).

3. Known and Hidden Defects

The strict dogma "Leased as seen" applies here. For obvious circumstances that the commercial tenant can determine themselves during diligent property viewings, the landlord's duty of disclosure remains completely silent (§ 536b BGB).

However, this differs for "hidden," substantial material defects about which a future tenant would not typically ask (because they assume the property is sound), but which the landlord knows about. These include (but are not limited to):

• Extremely hard-to-locate and constantly recurring blockages in the pipe system.
• The fact that neighboring plots host highly polluted, permanently emitting industrial plants.
• An acute, unresolvable asbestos contamination—this must be proactively disclosed (due to health risks).

Here, the "ancillary BGB duty" of early clarification by the landlord exists prior to contract signature.

Managing Your Commercial Documents with Landager

In commercial tenancy law, it is paramount above all to regulate contract contents meticulously and securely (to define handover conditions as "known" in case of a dispute). The provision of listings, handover logs—detailing all "defects"—and the central storage of constantly valid Energy Certificates is handled by the Landager portal, ensuring you and your commercial tenants can access a secured, verifiable communication protocol.
