The rental contract forms the legal basis for living in Germany and regulates the rights and obligations of tenants and landlords. For international professionals coming to Germany, it is crucial to understand the most important regulations in the rental contract. This article provides an overview of the central points that should be considered when concluding and during a tenancy.

Content of the rental contract

A rental contract should contain the following essential points:

• Names and addresses of the contracting parties
• Apartment address and living space
• Base rent: Basic rent without utilities
• Utilities (operating costs): it should be listed which services are included in these utilities, such as heating, water, waste disposal, or cleaning of common areas
• Total rent: the sum of base rent and utilities
• Deposit: amount (maximum three months’ base rent), payment process, and regulation for repayment
• Rental period and notice periods
• Date of rental commencement
• Due date for regular rent payment
• Rent increase regulations: if agreed – graduated rent or index-linked rent
• Use of common facilities: basement, attic, terrace, garden
• Existing damage: should be documented by the landlord in the contract

With this information, the rental contract ensures that all rights and obligations are clearly regulated and both tenants and landlords have legal security.

Graduated rent and index-linked rent

Some rental contracts have special regulations for rent increases.

• Graduated rent: the rent increases in fixed agreed steps at specific times, for example annually by a fixed amount. The increases are already stipulated in the rental contract at the time of conclusion and occur automatically. This provides planning security for both sides.
• Index-linked rent: the rent is linked to the development of living costs (consumer price index). If living costs rise, the landlord may increase the rent in the same proportion. However, the adjustment does not occur automatically – the landlord must announce the increase in writing and can do so at most once per year.

Types of rental contracts

There are various forms of rental contracts in Germany. Indefinite rental contracts are the norm – they run without a fixed end date and can be terminated with statutory notice period. Fixed-term rental contracts (time-limited rental contracts) only apply for a specific period. In Germany, they are only permissible under certain conditions: The landlord must state a legally recognized reason, such as owner-occupancy, planned renovation measures, or use as company accommodation. The fixed term can last from a few months to several years – there is no statutory upper limit. Common periods range from six months to several years, depending on the reason for the fixed term. Sublease contracts allow the main tenant to sublet part of the apartment, while remaining responsible to the landlord.

Apartment handover

The apartment handover is of great importance both when moving in and when moving out. A handover protocol should always be prepared together with the landlord and signed by both parties. This records the condition of the apartment, existing damage, and the number of keys handed over. A carefully maintained handover protocol serves as proof and helps avoid later disputes over repairs or the return of the deposit.

Damage in the apartment

Existing or newly occurring damage in the apartment should be reported to the landlord immediately. This includes, for example, damage from wear and tear, moisture, defective appliances, or other defects. Early reporting protects against later legal problems and ensures that necessary repairs are carried out in time. Ideally, damage should be documented in writing – photos and date are helpful.

Key regulations

Tenants are entitled to sufficient apartment keys – the number depends on the number of residents. Each resident, including children, is fundamentally entitled to their own key. Even single persons are entitled to at least two keys, for example to be able to deposit a spare key with a trusted person. The landlord may not keep a key without the tenant's consent.

What to do in case of key loss?

If the apartment key is lost, a locksmith often must be called. Costs currently generally range between 50 and 150 euros, depending on the time of day. After opening, proof of residence must be presented, and the invoice should be kept in case insurance covers the costs. When losing a building key – meaning the key for the front door in an apartment building – the approval of the property management is necessary. Replacement usually costs around 50 euros per key, but can be significantly more expensive with locking systems. Replacing a complete locking system can cost up to 5,000 euros. Private liability insurance covers such expenses in full. Information on liability insurance can be found here.

If the key is stolen, the landlord may not automatically transfer the costs to the tenant – this only applies if the tenant was at fault for the loss. To avoid problems, it is advisable to deposit a spare key with a trustworthy person.

Legal support through tenant protection

Tenants in Germany are protected by strict legal regulations. Support is provided by tenant protection associations, which can advise and legally represent tenants in conflicts with landlords. In this way, tenants can, for example, defend themselves against unlawful termination. Well-known examples include:

• Mieterbund
• Mieterhilfeverein
• Mieterengel

End of tenancy

A landlord may only terminate the tenancy under certain conditions: if a tenant fails to pay rent for two consecutive months, repeatedly violates the house rules, or the apartment is needed for owner-occupancy, for example for the landlord themselves or close relatives. The notice period for landlords is at least three months and extends to six months after five years of tenancy, and to nine months after eight years. A tenant can terminate at any time by observing the statutory notice period of three months – regardless of how long the tenancy has already existed.
A termination must be made in writing and contain the following information:

• Name and address of the landlord
• Apartment address with floor
• Date and notice period
• Signatures of all main tenants, if the termination comes from them

The termination must be received by the landlord no later than the third working day of a month for the current month to still count toward the notice period. Generally, confirmation is additionally requested and an appointment for key handover is arranged. Those who familiarize themselves early with their rights and obligations in the rental contract can avoid misunderstandings and create the foundation for a secure and stable tenancy in Germany.
