In commercial lease law, which has been primarily governed by the Bürgerliches Gesetzbuch (BGB) since its effective date of 1 January 1900, there is neither a rent cap (Mietpreisbremse) nor a Kappungsgrenze. Rent adjustments for commercial tenancies in North Rhine-Westphalia are governed exclusively by contractual agreements and general contract law. Landlords and tenants have broad freedom in designing rent adjustment mechanisms.

No Rent Cap for Commercial Properties The Mietpreisbremse (§§ 556d ff
BGB) applies exclusively to residential leases — not to commercial properties. The NRW Tenant Protection Ordinance (MietSchVO NRW 2025) also covers only the residential market. In commercial leases, the market rent is the only reference. There is no legal obligation to align with comparative rents or rent indices.
Rent Adjustment Mechanisms
Index Rent (Consumer Price Index)
The most common rent adjustment in commercial leases is the index rent — linking rent to the Consumer Price Index (VPI) of the Federal Statistical Office:
How It Works
New Rent = Current Rent × (New CPI / CPI at Contract Start)
Key Contract Provisions
- Adjustment interval: Typically annually or upon exceeding a defined threshold (e.g., 5% CPI change)
- Direction: Specify whether only increases or also decreases are permitted
- Reference index: Always use the current CPI of the Federal Statistical Office
- Form requirement: For commercial lease agreements with a term longer than one year, § 550 BGB (applied via § 578 BGB) requires 'written form' (§ 126 BGB). If this form requirement is not met, the lease is considered to be for an indefinite period and can be terminated with the statutory notice period.
Graduated Rent (Staffelmiete)
Graduated rent provides automatic increases at contractually fixed dates:
- Dates and amounts must be specifically named in the contract
- Unlike residential law, the increase can also be expressed as a percentage
- Independent rent increases alongside the graduation schedule are generally excluded
Turnover Rent
Particularly common in retail, hospitality, and hotels in NRW (e.g., Cologne city center, Düsseldorf shopping areas):
- Tenant pays a base rent plus a percentage of revenue
- Typical revenue share: 3–10% of net turnover
- Landlord must negotiate a right to audit turnover (Buchsichtigungsrecht)
- Tenant must provide monthly or annual revenue reports
Market Rent and Renegotiation
For very long lease terms (10–20 years), contracts often include renegotiation clauses allowing adjustment to market rents after specified periods:
- Obligation for both parties to negotiate (with arbitration as fallback)
- Appointment of an independent appraiser if no agreement is reached
- For NRW: market rents are established through broker comparisons and market reports (Bulwiengesa, JLL, CBRE)
Best Practices for Landlords
- Include index rent with a clear calculation formula and adjustment interval in the contract
- For turnover rent: secure strong reporting duties and audit rights contractually
- Protect escalation clauses for long terms with a minimum rent floor
- Coordinate the VAT option and rent adjustments tax-wise
- Monitor NRW market developments regularly (especially the dynamic Cologne/Düsseldorf office markets)
