Commercial Rent Increases in Mecklenburg-Vorpommern: Index, Graduated, and Turnover Rents

Commercial tenancy law follows the principle of freedom of contract: the statutory cap limit (Kappungsgrenze) and rent brake (Mietpreisbremse) apply exclusively to residential properties. Landlords of commercial premises in Mecklenburg-Vorpommern may therefore agree on rent increase mechanisms freely with their tenants.

No Statutory Framework for Commercial Rent Increases

Unlike residential law, commercial tenancies are not subject to:

This means: without a contractual provision, the landlord cannot unilaterally increase the rent. With the right clause, however, regular adjustments are straightforward.

Rent Increase Models

1. Index Rent (§ 557b BGB)

The most common rent adjustment mechanism for commercial properties. The rent is tied to the Consumer Price Index (CPI) of the Federal Statistical Office.

How it works:

• Base rent set at lease start
• Annual adjustment proportional to CPI change
• Adjustment triggered by written landlord notification

Example:

• Base rent: €2,000/month (September 2024)
• CPI increase through September 2025: 3.2%
• New rent: €2,000 × 1.032 = €2,064

2. Graduated Rent (§ 557a BGB)

Fixed increases at predetermined intervals:

Pros: Planning certainty, no negotiations needed Cons: No inflation protection, may lag behind costs

3. Turnover Rent

Common in retail and hospitality:

• Base rent (minimum guarantee) + variable percentage of tenant's revenue (e.g., 5–10%)
• Tenant pays the greater of the base rent or the turnover-based amount
• Requires tenant transparency (annual revenue reporting obligation)

Rent Adjustment Without a Contract Clause

Without a contractual provision, the landlord cannot increase the rent unilaterally. In that case, an increase requires:

• Mutual agreement (renegotiation with a new contract amendment)
• New lease at renewal

This is why including an adjustment clause at signing is essential.

Best Practices for Commercial Landlords

1. Include an index clause in every long-term lease — protects against inflation
2. Define the calculation formula clearly — avoid misunderstandings
3. Send adjustment notifications in writing — and on time
4. For graduated rents: state absolute amounts — not just percentages
5. Communicate operating cost increases separately from rent adjustments
