Everything you need to know about the rental agreement (lease)

What is a Mietvertrag (rental contract)?

A Mietvertrag is a written legal agreement that sets out the conditions for the use of a property, whether it is a flat, a house or a room. The tenant undertakes to pay rent in return for the use of the property. In turn, the contract guarantees the tenant the right to live in the property for as long as they comply with the agreed terms.

Types of rental contracts

1. Open-ended rental contract (unbefristet)
This is the most common type of contract and does not specify an end date. It remains valid until one of the parties terminates it, in line with the statutory notice periods.

2. Fixed-term rental contract (befristet)
In this type of contract, a specific rental period is agreed, for example one or two years. Early termination is usually only possible in exceptional cases explicitly mentioned in the contract.

Key clauses in a rental contract

• Contracting parties: Details of the landlord and the tenant.

• Description of the property: Exact address, number of rooms, size of the living space and any additional parts such as basement, parking space, balcony or garden.

• Rent amount (Kaltmiete): The basic rent without service charges or running costs.

• Additional costs (Nebenkosten / service charges): For example heating, water, cleaning of communal areas, waste collection, building management.

• Deposit (Kaution): A security deposit paid at the beginning of the tenancy, usually up to three months’ basic rent.

• Condition of the property: Documentation of the condition at the time of handover, often recorded in a handover protocol.

• Usage rights: For example use of the garden, laundry room, drying room, basement or bicycle storage.

Tenant’s rights

• Protection against sudden termination: The landlord may not terminate the contract without a legitimate legal reason.

• Right to stable housing: The tenant has the right to remain in the flat as long as the rent is paid and the contractual obligations are met.

• Basic maintenance and major repairs: The landlord is usually responsible for major repairs, such as heating problems, pipe damage or structural defects.

Tenant’s obligations

• Paying rent on time: Rent must be paid in full and on time, usually at the beginning of the month.

• Careful use of the property: The tenant must treat the flat carefully and avoid unnecessary damage.

• Reporting damage or defects: Any damage or malfunction (e.g. water leaks, heating failures) must be reported to the landlord immediately.

• Compliance with house rules (Hausordnung): Rules such as quiet hours, cleanliness in common areas and waste separation must be observed.

Termination of the rental contract

By the tenant
An open-ended rental contract can generally be terminated by the tenant with a notice period of three months, unless a longer notice period has been agreed in the contract.

By the landlord
For the landlord, termination is more difficult and requires a valid legal reason, for example:

• Personal use (Eigenbedarf): The landlord or close family members need the property for their own use.

• Breach of contract: For example, repeated and substantial arrears in rent payments or serious violations of the house rules.

Rent increases

The landlord may raise the rent, but only under strict legal conditions:

• Advance notice: A rent increase must generally be announced in writing at least three months in advance.

• Cap on increases: In most cases, the rent may not be raised by more than 20 % over a period of three years; in some cities or regions this cap is even lower.

Practical tips

• Read the contract carefully and in full before signing it, and ask for clarification of any clause you do not understand.

• Keep a signed copy of the contract and all written correspondence with the landlord.

• Document the condition of the property when you move in and when you move out, ideally with photos and a written protocol.

• Check the details of the Nebenkosten carefully, as they can vary significantly from one property to another.
