Berlin Commercial Tenancy Law: A Guide for Commercial Landlords

Unlike the highly regulated residential market, commercial tenancy law (Gewerberaummietrecht) in Germany is characterized by extensive freedom of contract (Vertragsfreiheit). Landlords in Berlin have significant leeway to negotiate terms, shift maintenance burdens, and dictate rent increases.

Commercial vs. Residential Law

The protective mechanisms standard in German residential leases largely do not apply to commercial properties:

Formal Lease Requirements (Update 2025)

The New Text Form Requirement

A major legislative change occurred on January 1, 2025 (Fourth Bureaucracy Relief Act). Previously, any commercial lease concluded for a fixed term of more than one year had to explicitly meet the strict "Written Form" (Schriftform) requirement—meaning physically signed on paper.

• Since 2025: The requirement has been lowered to Text Form (Textform).
• Impact: Commercial leases and their addendums can now be legally concluded and modified via email, PDF, or DocuSign, without requiring a wet-ink signature.

For more detail, see our Commercial Lease Requirements guide.

Security Deposits

There is no statutory limit on the amount of a commercial security deposit.

• Common practice in Berlin is 3 to 6 months' gross rent.
• The tenant has no statutory right to pay in installments.
• The landlord is not legally required to hold the deposit in a separate, interest-bearing insolvency-proof account (unless explicitly agreed in the contract).
• Bank Guarantees (Bankbürgschaften) are highly common in the commercial sector.

For more detail, see our Commercial Security Deposits guide.

Rent Increases

Because there is no Rent Brake (Mietpreisbremse) or Rent Index (Mietspiegel) for commercial spaces, rent increases must be agreed upon in the lease contract.

Common models in Berlin include:

• Index Rent (Indexmiete): Tied to the official Consumer Price Index (CPI).
• Stepped Rent (Staffelmiete): Fixed increases at specified dates.
• Turnover Rent (Umsatzmiete): A base rent plus a percentage of the tenant's business revenue (common in retail and gastronomy).
• Market Adjustment Clauses: Re-negotiating the rent to current market rates every 3–5 years via an expert appraisal.

For more detail, see our Commercial Rent Increases guide.

Eviction and Termination

Commercial tenants do not enjoy the same eviction protections as residential tenants. If the landlord wishes to end an open-ended lease, they do not need to provide a reason (such as "personal use").

Notice Periods (Ordinary Termination)

Unless otherwise agreed, the statutory notice period for commercial spaces (BGB § 580a) is almost six months: notice given by the 3rd business day of a calendar quarter ends the lease at the end of the following calendar quarter.

Fixed-Term Leases

Most commercial leases in Berlin are fixed-term (e.g., 5 or 10 years). These cannot be ordinarily terminated before the term expires, offering immense planning security for both sides.

Immediate Termination

Landlords can terminate immediately (fristlos) if the tenant falls into default with rent exceeding one month's rent for two consecutive dates, or an amount equal to two months' rent over a longer period. There is no grace period payment (Schonfristzahlung) in commercial law to retroactively heal the termination.

For more detail, see our Commercial Eviction Process guide.

Maintenance and "Triple-Net" Leases

Unlike residential law, commercial landlords can transfer almost all maintenance, repair, and operating costs to the tenant.

• Dach und Fach ("Roof and Structure"): The landlord usually remains responsible for the core building envelope, but even this can theoretically be transferred in individually negotiated contracts.
• Triple-Net (NNN) Leases: Very common for single-tenant buildings or large retail spaces, where the tenant bears property taxes, insurance, and all maintenance costs.
• Caution with AGBs: If using standard pre-formulated lease contracts, transferring the cost for replacing major items (like an entire HVAC system) without a financial cap can be ruled void by courts.

For more detail, see our Commercial Maintenance Obligations guide.

Late Fees and Default

• Higher Default Interest: For B2B transactions, the default interest rate is 9 percentage points above the Base Rate (compared to 5 points for residential).
• Lump Sum Damage: Landlords can automatically claim a €40 statutory lump sum for damages caused by the delay (BGB § 288 (5)).
• Contractual Penalties (Vertragsstrafen): Can be validly included in a commercial lease, provided they are not disproportionately high.

For more detail, see our Commercial Late Fees guide.

Berlin Specifics: Startups and Coworking

Berlin is Europe's startup capital. The commercial real estate market actively caters to this with:

• Shorter lease terms (1-3 years instead of the traditional 5-10 years).
• High demand for Sub-leasing (Untervermietung) clauses, allowing startups to downsize or upsize flexibly. Landlords should strictly regulate sub-leasing requirements in the contract.
• A massive shift toward serviced offices and coworking spaces, governed largely by general service contracts rather than pure commercial tenancy law.
