Whether you are a store owner, doctor or entrepreneur: anyone who wants to run their own business will sooner or later need their own premises. As soon as the premises are not used for private living, a commercial lease is concluded. As there is no separate commercial tenancy law and freedom of contract applies, tenants and landlords should inform themselves in detail about the legal situation. The following article provides a detailed overview of the most important aspects of a commercial lease.

1. commercial lease - definition and purpose of use 

A commercial lease agreement applies when premises are used commercially, i.e. for business purposes. The provisions are largely regulated in sections §§535ff and §580a of the German Civil Code (BGB), which cover general tenancy law. 

Commercial premises can be stores, doctors' surgeries, offices, restaurants or storage rooms, for example. 

In contrast to the private lease contract, the contracting parties are equal under commercial law; accordingly, the paragraphs protecting the tenant as opposed to the landlord do not apply. There is much more room for negotiation and freedom when drafting the contract: For example, there is no prescribed formal requirement for leases of less than one year. From this point of view, the entire drafting of the lease depends on the contracting parties.

Landlord and tenant can be: 

  • Natural persons
  • Legal entities (GmbH, AG, UG, etc.)
  • Commercial partnerships (OHG, KG)
  • Company under civil law (GbR)

2. form of a commercial lease agreement 

As already mentioned, commercial rental agreements do not necessarily have to be in writing, provided, however, that the rental period is less than one year . If the rental period exceeds one year, the contract must be concluded in writing, see BGB §550.

In general, however, a written contract is recommended even for a short rental period so that disputes cannot arise in the first place. 

3. content of the commercial lease agreement 

The content of rental agreements is often specified by the landlord. Nevertheless, tenants can also contribute suggestions for wording and content.  

As free as the landlord is in the drafting of the commercial lease agreement, the drafting of the agreement is subject to Section 307 of the German Civil Code (BGB ) and thus to content control. Content control means that no party may be "unreasonably disadvantaged" and all clauses must be formulated "clearly and understandably". 

In contrast, the contract may be concluded on the basis of joint negotiations between the landlord and the tenant. §Section 307 of the German Civil Code (BGB) then does not apply, provided that the content was not specified by the landlord and the principles of good morals (Section 138 of the German Civil Code (BGB)) and good faith (Section 242 of the German Civil Code (BGB)) are taken into account accordingly. 

Tip: In order to be on the safe side legally, it is advisable to consult a specialist lawyer for individual agreements. 

The following content points are important for both tenants and landlords: 

  • Names of the contracting parties
  • Subject of the contract
  • Rental deposit
  • Rental period and notice periods
  • Amount and type of rent (graduated rent, index-linked rent)
  • Description of the rental purpose

4. agreement on the purpose of use 

The exact wording of the rental purpose or intended use is very important for tenants, especially if the activity requires a permit. For example, a restaurant permit must be available for operating a restaurant in the commercial premises. 

It is the responsibility of the tenant to obtain the appropriate permits and authorizations for the operation of his business from the authorities. 

The landlord is responsible for fulfilling the agreed purpose of use. In the case of a restaurant, for example, this means complying with building or hygiene regulations. The landlord is liable for the suitability of the rental property at all times. This cannot be excluded by a corresponding clause in the rental agreement

The exact formulation of the purpose of use is also advantageous for the landlord: if the formulation is too general, the tenant can change his purpose of use on his own. The landlord then cannot and may not prevent this, but is still responsible for providing the premises to be used properly. 

5. term and termination options 

There are no statutory provisions for the term. Here, the lease can be concluded either for a fixed term or for an indefinite term. In the event that a fixed-term lease is to be extended, there is no need for action: the contract is tacitly extended in accordance with Section 545 of the German Civil Code (BGB ). 

If the tenant continues to use the property after the expiry of the rental period, the fixed-term contract automatically becomes an indefinite contract, unless one of the contracting parties objects to this within two weeks

Option clause for fixed-term commercial leases

In practice, most fixed-term commercial leases have a term of at least five years. Provided that business is good, the tenant finds himself in an unfavorable situation after the contract expires, because moving is particularly unfavorable for doctors or restaurants, for example. To prevent landlords from exploiting this situation by offering unfair terms, there is the option of agreeing an option clause in advance.  

Good to know: The option clause gives the tenant the right to extend the contract unilaterally. 

 

Termination options 

In the case of fixed-term contracts, the tenancy agreement usually ends at the end of the agreed rental period without the need for a corresponding notice of termination, unless an option clause has been agreed. 

An indefinite contract may be terminated depending on the individual agreement of the notice periods. If no notice periods have been agreed, the statutory notice periods apply: 

Legal notice period: 

Pursuant to Section 580a of the German Civil Code (BGB ), the statutory period of notice is 6 months, provided that the notice of termination was served no later than the 3rd working day of the quarter. Otherwise, it is extended to 9 months

Important to know: For commercial leases, Saturday also counts as a working day

Extraordinary termination: 

In addition, there is the option of extraordinary termination for both fixed-term and permanent contracts. 

This is usually possible in the following cases in particular: 

  • Legal: Important reasons that enable extraordinary termination by law can be disturbance of the peace, unauthorized subletting, serious breaches of contract and much more. 
  • Contractual: reasons contractually agreed in advance, for example insolvency 

In practice, in the case of minor violations, the other party is given the opportunity to change its behavior by means of a warning before extraordinary termination occurs. 

 

Special termination rights: 

In addition, there are special termination rights that can lead to premature termination of the lease. These special termination rights apply in the following cases: 

Insolvencies: 
  • In the event of the tenant's insolvency, the insolvency administrator may terminate the lease with three months' notice to the end of the month
  • In the event of the insolvency of the landlord, the new owner shall have a special right of termination subject to the statutory notice period in the event of the sale of the premises by the insolvency administrator. 

Refusal to sublet: 

If subletting is not expressly excluded in the lease agreement, the tenant may exercise his special right of termination in the event of refusal on the part of the landlord. 

Modernization measures: 

In the event that the landlord wishes to carry out a modernization of the business premises, the tenant may give extraordinary notice of termination, provided that it concerns measures that significantly affect the leased premises. The landlord has a duty of notification and must inform the tenant three months before the start of the planned work. 

Death of a tenant:
  • If the tenant dies, both heirs and the landlord may terminate the tenancy extraordinarily in compliance with the statutory notice period. (§ 564 BGB) 
  • If there are several tenants,the heir can terminate the lease together with the other tenants in accordance with § 563a of the German Civil Code (BGB), also subject to the statutory period of notice. The landlord has no special right of termination in this constellation. 

Foreclosure: 

In the event of a foreclosure sale, the new purchaser also has the right to terminate the contract on the first possible termination date after acceptance of the bid, irrespective of whether the contract is for a limited or unlimited period. If the new purchaser does not terminate the contract on the first possible date, the special right of termination expires. 

6. amount of rent and operating costs

The amount of the rent is usually agreed individually. There are no legal restrictions, such as a local rent index. The rent that the landlord can demand depends on the property, the location and the comparative rents

In the rarest cases, there is still a fixed-price rent. As a rule, landlords charge index or graduated rents. In the case of index-linked rents, the landlord can increase the rent accordingly in line with the consumer price index. In the case of a graduated rent, the rent increases annually by the corresponding contractually agreed amount. 

Index-linked rent: What does this mean and how does the adjustment work?

The index-linked rent is a form of rent that is based on the cost of living for all private German households. This is based on the consumer price index (CPI) published by the Federal Statistical Office. If this index rises, the rent increases accordingly. The price change compared to the previous year is referred to as the inflation rate.

How is the index-linked rent calculated?

The calculation is based on the percentage change in the index level. The formula is as follows:

(new index level / old index level x 100) - 100 = percentage index increase(new index level / old index level x 100) - 100 = percentage index increase

The rent is adjusted on the basis of this increase. However, this does not mean that the rent is automatically increased every year - there is only the option to do so.

Important regulations for landlords and tenants

  1. Obligation to give notice: The landlord is obliged to inform tenants of the adjustment in good time, for example by e-mail.
  2. At least one year apart: There must be at least one year between two rent increases.
  3. Adjustment on both sides: If the consumer price index falls, tenants can also demand a corresponding downward adjustment.

The index-linked rent is therefore directly linked to the development of inflation. If the cost of living rises, the rent increases. However, this also works in the opposite direction, which tenants should bear in mind.

This model enables both transparency and flexibility - for landlords and tenants alike.

Incidental expenses

There is also freedom of design with regard to ancillary costs. In practice, however, the ancillary costs, similar to those in residential leases, are calculated on a pro rata basis from the classic operating costs such as garbage collection, janitorial services, and consumption-dependent water and heating costs. 

For tenants, it is essential to clarify in advance whether there are any other additional costs, such as security services or the like. 

Rental deposit

There is also no legal basis for the rental security or deposit. The amount is freely negotiable and, depending on the sector and the duration of the tenancy, it may well be more than three months' rent.

7. maintenance of the rental property: rights and obligations

The maintenance of a rental property includes measures that are necessary to prevent wear and tear, ageing or weather damage and to preserve the original condition of the property. There are some important legal regulations and differences between private and commercial tenancies that need to be observed.

Who bears the costs of maintenance?

In principle, the maintenance of the rented property is one of the landlord's main obligations. This is regulated in Section 535 Paragraph 1 Sentence 2 BGB. Although there is no general maintenance obligation for property owners, the landlord must ensure that the rented property remains in a contractually compliant condition.

Important: A distinction must be made between maintenance (preservation of the target condition) and repair (restoration in the event of deviations from the target condition).

Private rental: Restrictions on transfer to tenants

In private tenancy law, the transfer of the maintenance obligation to the tenant is generally not permitted, especially in form contracts. This is a result of the law on general terms and conditions. There are only exceptions for so-called minor repairs:

  • Minor repairs: These may be contractually transferred to the tenant, provided they relate to parts of the rented property that are frequently used by the tenant (e.g. door handles, light switches).
  • Maximum amount: A financial limit for such repairs must be clearly defined in the rental agreement.

Commercial lease: Transfer to the tenant possible

The legal situation is different in commercial tenancy law. Here, the maintenance obligation can be transferred to the tenant in accordance with the case law of the Federal Court of Justice, as long as the obligation relates to damage caused by the tenant's use of the property or falls within the tenant's area of responsibility.

Warranty liability or exclusion of liability

The landlord is liable for defects in the rented property at the start of the tenancy and for other defects that were not caused by the tenant (Section 535 BGB). Warranty liability covers defects at the time of handover and damage that is not attributable to the tenant. A general exclusion of liability is not permitted in private tenancy law, particularly in form contracts.

In commercial tenancy law, exclusions of liability are permissible as long as they do not constitute an unreasonable disadvantage. Clear and legally secure agreements protect both parties from conflicts.

Protection against competition in commercial leases

Protection against competition protects tenants from economic disadvantages caused by direct competitors in the same rental property. It can be contractually regulated (e.g. exclusion of certain sectors) or take effect automatically if the principle of good faith is breached (Section 242 BGB). Without a contractual provision, there is no legal entitlement. Landlords and tenants should therefore make clear agreements in order to avoid conflicts and protect the tenant's economic interests.

Permits from authorities

In principle, the tenant is responsible for obtaining the necessary official permits, particularly in the commercial sector. This includes building permits, operating licenses and other official requirements. The landlord must ensure that the property complies with the general legal requirements. If permits are missing, the tenant may be prohibited from using the property and the landlord may be liable for damages due to a lack of cooperation. Clear provisions in the rental agreement are crucial here.

Frequently asked questions

What should you keep in mind when signing a commercial lease?

In a commercial lease agreement, the leased property, the parties to the contract, the intended use, the rent amount, utility costs, the term, notice periods, and other factors should be clearly defined. Commercial lease law allows for greater contractual freedom than residential lease law. Therefore, the specific terms of the contract are particularly important. The intended use is central. It determines whether the premises may be used, for example, as an office, medical practice, retail space, restaurant, or warehouse. Official permits, protection against competition, operating costs, index-linked rent, graduated rent, and special termination rights should also be reviewed before signing the contract. For long-term commercial leases, the form of the contract is also important. As of 2025, leases with a term of more than one year must generally be concluded in writing if the agreed term is to be secured.

What are the utility costs included in a commercial lease?

In a commercial lease agreement, ancillary costs can generally be specified in the contract. Typical ancillary costs include heating, water, sewage, waste disposal, property tax, building insurance, and others. For commercial spaces, additional costs may apply, such as administrative fees, security services, center management, or contributions to advertising associations. It is crucial that the lease clearly specifies which costs are to be borne in addition to the rent and how they are billed. Unclear provisions regarding ancillary costs can quickly lead to disputes over advance payments, flat rates, and additional charges.

Is a 10-year commercial lease permissible?

Yes, a commercial lease agreement with a term of 10 years is permissible. Under commercial lease law, the parties are generally free to agree on the term. Longer terms often make sense for retail spaces, medical practices, restaurants, or larger investments because they provide planning certainty. It is important that the agreement be in writing. If a commercial lease agreement with a term of more than one year is not concluded in writing, it is deemed to have been concluded for an indefinite period. The lease is not automatically invalid in this case, but it may be subject to ordinary termination. Another limitation concerns extremely long terms: leases exceeding 30 years may generally be terminated extraordinarily after 30 years with the statutory notice period. This does not apply to a standard 10-year lease.

What is the notice period for a commercial lease?

The notice period depends on whether the commercial lease was entered into for a fixed term or is open-ended. A fixed-term commercial lease generally ends upon the expiration of the agreed term. Ordinary termination during the term is only possible if it was contractually agreed upon or if a special statutory right of termination applies. For an open-ended commercial lease agreement, the contractually agreed notice period applies. If no such provision exists, § 580a of the German Civil Code (BGB) applies. According to this provision, notice of termination must be given no later than the third business day of a calendar quarter for termination at the end of the next calendar quarter. In practice, this usually corresponds to approximately six months before the end of the quarter.

When is a commercial lease invalid?

A commercial lease agreement may be invalid if essential requirements are missing or if it violates mandatory law. This can be the case, for example, if there is no agreement on the leased property or the rent, if there is a lack of authority to act on behalf of a party, if there are agreements contrary to public policy, or if there are invalid clauses in standard-form contracts. Not every error renders the entire contract invalid. In the case of pre-formulated clauses, even a single provision may be invalid, for example, if it is unclear or unreasonably disadvantages one party. A formal defect in long-term commercial lease agreements also does not automatically render the agreement invalid. If the required written form is not observed, the agreement is generally deemed to have been concluded for an indefinite term and may be subject to ordinary termination.
