Flexible Office Lease vs. Traditional Commercial Lease

What You Should Know as a Tenant

Are you looking for new office space in Berlin for your company? If so, you're facing an important decision: Do you want to for years on a property Do you want to stay in the capital, or do you prefer maximum flexibility? For small and medium-sized enterprises (SMEs), entrepreneurs, attorneys, and tax advisors, this question is not just a budgetary one, but also a strategic one.

This guide examines all legal and tax-related aspects and compares commercial leases with modern flexible concepts.

An Overview of the Three Main Lease Models for You as an Office Tenant

Companies looking to lease office space will encounter three essential types of lease agreements on the market:

• Standard Commercial Lease Agreement: Under the German Civil Code (BGB), the standard commercial lease agreement serves as the legal basis. This type of contract allows you to plan for the long term and design the space with maximum flexibility. However, you should often expect a long-term commitment of 5–10 years.
• Office as a Flex Model (Flexible Workspace): Modern lease agreements with short terms and flexible renewal options are the major advantage of Flex Offices.
• Contract with a business center (service agreement): This type of contract combines rent with services. You receive, in a Business Center not just an office, but can also use the existing Infrastructure such as reception services, Internet, furniture, and cleaningI use them. In most cases, these services are already included in the rent.

What should you look out for in a commercial lease agreement?

If you rent an apartment as a private individual, you benefit from tenant protection. In the case of commercial leases, however, there is freedom of contract, which means that contracts—including their clauses—can be freely drafted and negotiated. If you look closely at these contracts, you’ll often find that this works to the tenant’s disadvantage.

When reviewing a commercial lease agreement, we recommend that you pay particular attention to the allocation of maintenance costs, the definition of the intended use of the property, and the contractually stipulated rent adjustments (indexed rent). Carefully review the sample commercial lease agreement to avoid costly retroactive payments or the contract becoming invalid prematurely.

What distinguishes a commercial lease from a residential lease?

The most significant distinction lies in the level of protection and the intended use.

Residential tenancy law provides protection for tenants, including strict safeguards against eviction and caps on rent increases. In the case of a commercial lease, the contract is entered into by two business entities, which means, for example, that protection against termination for the landlord’s own use does not apply. Furthermore, rent control does not apply to commercial properties.

What regulations should one expect under commercial lease law?

When it comes to the leasing of commercial premises, the German Civil Code (BGB) refers only to a limited number of specific provisions (including Sections 578 and 566 of the BGB); instead, general provisions of lease law generally apply in such cases. The most important ones are:

• Formal Requirements (Section 550 of the German Civil Code (BGB)): Contracts with a term of more than one year must be set forth in writing. In addition, these contracts must be signed by hand by both parties. Failure to comply with these requirements may result in the contract being converted to an indefinite term and becoming subject to early termination.
• Notice periods (Section 580a of the German Civil Code (BGB)): If no notice periods have been agreed upon in the contract, the statutory notice periods apply. These are generally not very long: Notice of termination must be submitted no later than the third business day of a calendar quarter for termination effective at the end of the next calendar quarter (a notice period of nearly 6 months).

What mandatory provisions must be included in a commercial lease agreement under the German Civil Code (BGB)?

To ensure legal certainty, the strict written form requirement of § 550 of the German Civil Code (BGB) must be observed, and the following key aspects must be clearly and comprehensively agreed upon:

1. The Rental Property: The contract must include a detailed description of all rooms, parking spaces, and basements (including square meter measurements), and it is best to attach a floor plan with a colored border as an appendix.
2. The parties to the agreement: The tenant and landlord must be identified by name. In the case of a GmbH or UG (limited liability), the company name must be provided, including its commercial registry number. The managing directors authorized to represent the company must also be listed.
3. Contract Term & Termination: The contract must specify the exact start date of the contract, the end date in the case of fixed-term contracts, and any possible renewal options.
4. Service Charges & Rent Allocation: The breakdown into net rent (excluding utilities), the advance payment for operating costs, and the sales tax must be specified.
5. The purpose of the lease: The lease must clearly specify what a tenant is permitted to do in the office (e.g., „use as a training center and for software development"). If the purpose is defined too narrowly, it may be more difficult for the company to adjust its strategy later on. If, on the other hand, the purpose is defined too broadly, landlords often reject it.

§ 4 No. 12 of the Value-Added Tax Act (UstG): Value-Added Tax Under a Commercial Lease Agreement

Founders often underestimate the tax implications, whereas tax advisors always examine them first.

Which types of rentals are tax-exempt under the German Value-Added Tax Act (Section 4, No. 12)?

The law generally states that the leasing and renting of buildings and land are tax-exempt. This means that a landlord is normally not allowed to charge sales tax on the rent.

Option (Section 9 of the Value-Added Tax Act)

Tax exemption is a major disadvantage for landlords, as it means they lose the right to claim input tax credits for renovations, construction work, or bills from contractors. The law therefore allows landlords to opt to apply sales tax (§ 9 UStG).

However, this option is permitted only if the tenant uses the property exclusively for transactions that do not preclude input tax deduction.

Important information for tenants: If you run a startup that is eligible for input tax credits—such as an agency—the sales tax option should be treated as a neutral item for your business. This means that you pay the tax to the landlord and then claim a refund from the tax office.

Is the commercial rent gross or net?

The answer to this question may vary depending on the terms of the lease agreement. In most cases, landlords and tenants agree on a net rent excluding utilities. If this option is selected in the lease agreement, the statutory value-added tax of 19% is added to this net rent excluding utilities. The tenant should therefore ensure that the following wording is included in the lease agreement: „The rent is a net rent plus the applicable statutory value-added tax."

Points to note regarding tax exemptions: If you run a company in the medical sector, a financial services firm, or an insurance company, you are not considered eligible to claim input tax credits. If the landlord opts to charge sales tax, you will effectively pay 19% more in rent. Therefore, it is essential that you ensure the sales tax option is explicitly excluded from the contract.

Important things for tenants to check before signing a lease

If you are presented with a sample commercial lease agreement, be sure to carefully review the following clauses:

1. Indexation and Rent Adjustment Clauses

With a 10-year lease term, you can rarely count on a fixed rent. Indexation clauses are almost always included in the lease agreement. These clauses are tied to the Consumer Price Index (CPI) published by the Federal Statistical Office.

When inflation rises, rent also increases. Therefore, you should ensure that the agreed-upon adjustment is fair: An increase should only take effect once the index has changed by at least 5-10%; this is considered the threshold. An index adjustment should therefore not take effect with every slight rise in inflation.

2. Maintenance Obligations

According to the German Civil Code (BGB), the landlord is responsible for the heating system, the roof, and the walls of a property. In reality, however, landlords often pass these costs on to the tenant.

• What is allowed? The landlord may require the tenant to perform repairs on items that are within the tenant’s direct control. These include, for example, interior doors, light switches, or window handles. The costs are usually capped at a maximum amount per year (e.g., no more than 10% of the annual net rent excluding utilities).
• What is not allowed? The landlord may not pass on repair costs for repairs to „the roof and structure." This refers to work on walls or the facade, as well as the roof. If you find such clauses in the lease agreement, you may consider them invalid. (Load-bearing walls, roof renovation, facade).

3. Protection Against Competition

This concerns a very important point in the Berlin commercial lease agreement for retail stores, but also Law Firms or agencies. Landlords often own multiple spaces within a building or neighborhood. If a non-compete clause isn't included in the lease, you might soon find yourself competing with a rival right next door.

4. Cosmetic Repairs

When signing the lease, you should carefully review the condition in which the rented office must be returned at the end of the lease term. According to the Federal Court of Justice, deadlines for renovations—such as a clause requiring you to paint the walls every three years—are also invalid. Such an obligation may only be imposed flexibly, depending on the actual degree of wear and tear.

Terminating a Commercial Lease: How Can Your Company Get Out of a Commercial Lease?

Anyone who wants to terminate a fixed-term commercial lease early will face significant challenges. However, if you absolutely must do so, you have three options:

• Give proper notice: Termination under normal circumstances is only possible if a commercial lease agreement was entered into for an indefinite term. In this case, statutory notice periods (as mentioned above) or notice periods agreed upon individually apply.
• Terminate the employment contract immediately without notice: Extraordinary termination without notice applies exclusively to serious breaches of contract (Section 543 of the German Civil Code (BGB)). This may be the case, for example, if the landlord permanently blocks access to the office or if there are significant health hazards (such as asbestos or mold).
• Successor Tenant Clause & Special Right to Terminate: Some tenants agree in advance, through a contract with the landlord, on special termination rights or a successor tenant clause. This can help the tenant terminate the lease early, for example, by making special payments or if a suitable successor tenant is found.

Business Center Contract or Flex Contract Office—which option is a better fit for you?

Traditional lease agreements are often a good fit for companies that have a clear space concept or want to commit to a long-term arrangement. Agile small and medium-sized businesses and startups that value flexibility opt for finding an office more and more for a business center contract or a flexible office contract.

CapEx (Capital Expenditures) vs. OpEx (Operating Expenses): The Economic Drivers

• Standard Lease Agreement = High capital expenditures (CapEx) must be expected here. Those who opt for a traditional lease typically invest first in renovating the space, installing wiring, purchasing furniture, setting up kitchenettes, and paying the high commercial security deposit, which often amounts to 3–6 months’ rent. For companies, this means a long-term tie-up of capital.
• Flex model = With this model, there are minimal to low upfront costs; instead, the focus is on operating costs. The good news: These costs can be fully planned for. With this type of contract, you pay a monthly fee and can connect directly to existing infrastructure (kitchenettes, IT, Conference rooms). For your business, this means preserving your cash flow right from the start and throughout any potential growth phase.

Recommendations for Action & Conclusion

Traditional commercial lease agreements offer long-term planning certainty and give tenants the feeling of having „their own space." At the same time, however, these agreements also require a significant capital commitment and, particularly due to their long terms, pose a major risk to the company.

SMEs and entrepreneurs with Teams that will grow over the next 1–2 years Those who opt for a Flex contract or a business center contract gain significantly greater security—both operationally and financially.
