Overview of Disclosure Obligations

Energy Certificate for Commercial Buildings The Building Energy Act (GEG) requires landlords of non-residential buildings to present an energy certificate:

• Actively show the certificate during viewings
• Hand over the certificate to the tenant at lease signing
• Include energy data in property listings
• Certificates are valid for 10 years

Fine: Up to €15,000 for non-compliance. For non-residential buildings over 500 m² with significant public traffic, the certificate must be publicly displayed.

Pre-Contractual Duty of Disclosure Under general civil law principles (§ 311(2) BGB, culpa in contrahendo), the landlord must disclose all material circumstances relevant to the tenant's decision:

• Known structural defects (leaks, moisture damage, mold)
• Noise or odor emissions from the surroundings (e.g., nearby industrial plant)
• Regulatory orders or pending administrative proceedings affecting use
• Competition clauses in other lease agreements in the same property

Contamination and Soil Pollution

Particularly relevant for industrial sites, former gas stations, or production locations in NRW:

• Known contamination or soil pollution must be disclosed before signing
• Concealment may trigger rescission and damage claims
• A contamination register (maintained by NRW environmental authorities and municipalities) should be consulted

Recommendation: Commission a soil survey before leasing industrial land.

VAT Option (§ 9 UStG) Commercial property rental is generally VAT-exempt

Landlords may opt for VAT liability — this is economically beneficial when the tenant is entitled to input tax deduction. With the VAT option:

• 19% VAT is added to the rent
• The landlord can deduct input VAT from construction and renovation costs
• The option must be clearly documented in the lease
• Prerequisite: tenant uses the space exclusively for VAT-liable purposes

: If the tenant later changes use (e.g., partially VAT-exempt use), the landlord's input tax correction obligation may be triggered. Secure this in the lease.

Heritage Protection in NRW Numerous commercial properties in NRW — particularly in Cologne, Düsseldorf, Münster, and the Ruhr area — are protected as historic buildings

Landlords must:

• Inform the tenant about existing heritage protection status
• Explain which use and modification restrictions apply
• Clearly regulate approval requirements for tenant fit-out

Modifications to heritage-protected commercial buildings require approval from the relevant lower monument authority in NRW.

Building Permit and Use Type The landlord must ensure that the permitted use type matches the tenant's intended use

If the use does not conform to the building permit, the landlord bears the liability risk. Recommendation: Verify the registered use type and building permit status before signing.

Best Practices for Landlords

• Create a due diligence folder for each property (energy certificate, contamination status, heritage status, building permit)
• Inform prospective tenants about all known material circumstances before signing
• Coordinate the VAT option with the tenant and tax advisor
• Have contamination professionally assessed early — not after a tenant lawsuit
