Residential Lease Requirements in Schleswig-Holstein

The nationwide regulations of the German Civil Code (BGB) apply to all residential lease agreements in Schleswig-Holstein. Although a lease agreement can theoretically be concluded without any formal requirements, there are numerous legal stipulations and limitations that landlords must be aware of—particularly regarding invalid clauses in pre-formulated standard contracts (AGB).

Written Form and Formal Requirements

Oral vs. Written Contracts

• Lease agreements for residential space can generally be concluded orally (verbally).
• If a tenancy is fixed for a period longer than one year, the written form is mandatory (BGB § 550). If this requirement is not met, the contract is automatically deemed to correspond to an indefinite duration and can be terminated with standard legal notice.
• In practice, the written form with original signatures is almost exclusively chosen and strongly recommended for evidentiary purposes.

Mandatory Contents of a Lease Agreement

A lease agreement in Germany should contain at least the following information:

Fixed-Term Leases (Zeitmietverträge)

In residential tenancy law, limiting a lease to a fixed term is only permissible if the landlord provides a legally recognized reason in writing upon signing (BGB § 575):

• Personal Need: The landlord needs the premises for themselves or their family after the term ends.
• Extensive Renovation: Planned demolition or major structural alterations where a continued tenancy would hinder the work.
• Company Housing: The dwelling is to be rented to an employee.

The reason for the limitation must be stated in writing in the contract. If it is missing or deemed insufficient, the contract is automatically converted into an indefinite lease, preventing the landlord from enforcing the move-out date.

Frequently Invalid Clauses (AGB Control)

The Federal Court of Justice (BGH) has declared numerous standard clauses in pre-formulated lease agreements (Formularmietverträge) invalid:

Cosmetic Repairs (Schönheitsreparaturen)

• Rigid Deadlines: Clauses stipulating fixed intervals (e.g., "The kitchen must be painted every 3 years regardless of condition") are invalid.
• Valid Clauses: Only "soft" or flexible schedules tied to the actual need for renovation are permissible.
• End Renovation: Clauses demanding a final renovation upon moving out are generally invalid if the apartment was handed over to the tenant unrenovated at the start of the lease.

Small Repair Clause (Kleinreparaturklausel)

• Valid only up to approx. €100–120 per individual repair and subject to an annual total limit (usually 6–8% of the annual net cold rent).
• The tenant must only bear the costs; the landlord must organize and commission the repair.

Pet Ownership

• A general prohibition of all pet ownership is invalid (BGH VIII ZR 168/12).
• A reservation of consent clause is permissible: The keeping of small animals (hamsters, fish) is generally permitted, while the keeping of larger animals (dogs, cats) requires the landlord's permission based on individual case reviews.

Subletting

• A general prohibition against subletting is invalid. The tenant has a right to demand permission to sublet part of the apartment if they have a legitimate interest (BGB § 553).

Distinctive Features in Schleswig-Holstein

Since the rent brake does not apply in Schleswig-Holstein, the associated contractual obligations are omitted:

• No disclosure of previous rent: There is no requirement to disclose the prior tenant's rent to the new tenant before signing (BGB § 556g does not apply).
• No pre-contractual information duty regarding exceptions to the rent brake.

Tips for Landlords

• Use Professional Templates: Use continuously updated, legally verified contract templates (e.g., from Haus & Grund or other landlord associations).
• Avoid Rigid Renovation Clauses: The risk of invalidating the entire cosmetic repair transfer is high.
• List Utilities Clearly: The scope of operating costs must be explicitly listed in the contract, ideally by referencing the BetrKV.
• State Square Footage Accurately: A deviation of more than 10% between stated and actual living space can lead to a statutory right for the tenant to reduce rent.
• Document Fixed-Term Reasons: Clearly articulate the reasons for any fixed-term leases in writing.
