Commercial Rent Increases in Bavaria: Index, Graduated, and Turnover Rent

Commercial rents in Germany are not subject to any statutory caps like the Mietpreisbremse or Kappungsgrenze that apply to residential properties. However, since most commercial leases are fixed-term (5–10 years), rent increases must be pre-agreed in the lease — there is no statutory mechanism for mid-lease adjustment.

1. Index-Linked Rent (Indexmiete)

The most common rent adjustment mechanism in Bavarian commercial leases ties the rent to the Consumer Price Index for Germany (VPI) published by the Federal Statistical Office.

Requirements for Valid Index Clauses (Preisklauselgesetz)

• The lease must bind the landlord for at least 10 years (through fixed term plus any tenant renewal options)
• The clause must reference the official German CPI
• Trigger thresholds are common: rent adjusts only when the CPI changes by a specified percentage (e.g., 3%, 5%, or 10%)
• Full automatic sliding clauses (continuous monthly adjustment) are common and enforceable in commercial leases

Best Practice

• Use percentage changes rather than absolute index point values, as the CPI's base year changes periodically (e.g., 2015=100 to 2020=100)
• Clearly specify whether adjustments are automatic or require written notice from the landlord

2. Graduated Rent (Staffelmiete)

A straightforward alternative where specific rent amounts or increases are fixed at the time of signing:

• Example: "Rent is €2,000/month from 2025, €2,100 from 2026, €2,200 from 2027"
• Provides certainty for both parties
• No statutory restrictions on the frequency or amount of increases (unlike residential graduated rent)
• Disadvantage for landlords: If inflation significantly exceeds the agreed steps, the landlord cannot adjust further

3. Turnover-Based Rent (Umsatzmiete)

Common for retail and gastronomy in Bavarian cities (especially Munich's shopping centers):

• Typically combines a base rent (minimum guarantee) plus a percentage of net turnover above a threshold
• Example: €1,000 base rent + 6% of monthly net turnover exceeding €16,000
• Requires detailed contractual provisions for:
  • How and when turnover is reported (monthly/quarterly/annually)
  • Independent audit rights for the landlord
  • Definition of "net turnover" and excluded items

4. Modernization-Based Increases

Unlike residential law (which grants an automatic 8% modernization surcharge under § 559 BGB), commercial landlords have no statutory right to increase rent after modernization. Any modernization-related increase must be:

• Explicitly pre-agreed in the lease as a contractual provision, OR
• Negotiated as an amendment (often paired with a term extension as consideration)
