Commercial Rent Increases in Saxony: A Landlord's Guide

Unlike residential tenancy law, which heavily restricts rent increases to the local comparable rent or strict maximum percentages, commercial tenancy law in Saxony is based on freedom of contract.

In the commercial sector, the Rent Brake (Mietpreisbremse) and the Rent Cap (Kappungsgrenze) do not apply. This means a commercial landlord in Dresden or Leipzig has exactly the same freedom to negotiate as a landlord in a rural Saxon village. However, this freedom means rent increases only occur if a specific mechanism is explicitly agreed upon in the commercial lease agreement.

1. The Index-Linked Rent (Indexmiete)

The index-linked rent is the most common rent adjustment mechanism in German commercial leases, particularly for long-term office, logistics, or industrial contracts. It protects the landlord's rental income against inflation by tying the rent to the Consumer Price Index (CPI) (Verbraucherpreisindex or VPI), published monthly by the Federal Statistical Office (Statistisches Bundesamt).

How It Works

• The lease states that the rent will increase (or theoretically decrease) by a defined percentage if the CPI changes by a certain threshold (e.g., "if the index increases by 5% or 10 points compared to the base year").
• Real Adjustments: Often, the contract passes on 100% of the CPI increase to the rent, but landlords and tenants can negotiate an 80% or 90% proportional clause.

Validity Rules (The PrKG)

The German Price Clause Act (Preisklauselgesetz or PrKG) strictly regulates index clauses to prevent runaway inflation driving catastrophic rent hikes. For an index clause to be legally valid in a commercial lease:

• The landlord must be bound to the lease for at least 10 years. (This means the lease must have a fixed term of at least 10 years, or the tenant must have unilateral extension options bringing the total potential duration to 10 years without the landlord being able to terminate early).
• If the lease is shorter than 10 years, an automatic indexation clause is void.

2. The Stepped Rent (Staffelmiete)

A stepped rent (Staffelmiete) agreement is highly predictable for both parties and is commonly used in retail and gastronomy leases or periods following a major tenant build-out.

How It Works

• The lease contract dictates exactly when and by what specific Euro amount the rent will increase over the term of the lease.
• Example: "Base rent €2,000/month (Years 1-2); €2,200/month (Years 3-4); €2,500/month (Year 5)."

Key Characteristics

• There are no statutory waiting periods (unlike residential law).
• The amounts are completely freely negotiated.
• A stepped rent agreement provides zero protection against massive, unexpected inflation (which is why landlords prefer index rents for 10-year leases).

3. The Turnover Rent (Umsatzmiete)

In the retail, hotel, and gastronomy sectors in Saxony, turnover-based rent is standard practice. The landlord shares in the tenant's commercial success while providing the tenant with a lower fixed overhead during slow periods.

How It Works

• A Minimum Base Rent (Sockelmiete or Mindestmiete) is paid monthly regardless of sales.
• The Turnover Rent (Umsatzmiete) is calculated as an agreed percentage (e.g., 5% to 8%) of the tenant's net annual turnover generated specifically on the leased premises.
• If the calculated turnover rent exceeds the base rent, the tenant pays the difference at the end of the accounting year.

Drafting the Clause

Drafting a turnover clause is complex and highly scrutinized. The lease must meticulously define:

• Exactly what constitutes "net turnover" (e.g., excluding online sales simply shipped from the store, excluding employee discounts).
• The tenant's obligation to provide audited, certified annual revenue reports within a specific timeframe (e.g., by March 31st of the following year).
• An explicit "Operating Obligation" (Betriebspflicht), legally forcing the tenant to keep their store open during customary business hours to actively generate the turnover.

Combining Rent Adjustment Mechanisms

Can a commercial landlord combine these mechanisms? Yes, but carefully:

1. Staffelmiete + Indexmiete: You cannot apply both mechanisms simultaneously to the same base rent. However, you can agree to a staggered rent for the first 3 years of a lease, followed by an index-linked rent for the remaining 7 years.
2. Turnover Rent + Indexmiete: This is a very common combination. The Minimum Base Rent (Sockelmiete) is tied to the CPI (Indexmiete) to protect against inflation, while the turnover percentage sits on top.

Best Practices for Landlords in Saxony

1. Ensure the 10-Year Rule: Never insert an automatic index clause into a standard 5-year lease without tenant extension options, as the clause will be void under the Price Clause Act.
2. Mandate Audits: For turnover rents, require the tenant to submit revenue figures audited by a certified tax advisor (Steuerberater) to prevent fraudulent under-reporting.
3. Draft the Base Rent Properly: Always ensure your base minimum rent covers your fixed financing and maintenance costs before relying on variable turnover percentages.
4. Demand Operating Obligations: Always pair a turnover lease with a strict contractual operating obligation to prevent the tenant from simply pivoting their business model or quietly converting the retail space into storage.
