Residential lease agreements in Lower Saxony are based on the strong tenant protection rights of the German Civil Code (BGB), which originally came into force on 1 January 1900. Landlords should avoid standard contracts that contain outdated or non-legally compliant clauses, as these often become entirely invalid, leaving the tenant in a better position ("applicable BGB law instead of an invalid clause").

Written Form and Oral Contracts
Although a lease agreement for living space is also valid orally, the written form is strongly recommended for reasons of proof. If a contractual tenancy is concluded for more than a year without written documentation, it automatically counts as concluded for an indefinite period (§ 550 BGB).
A signed version (manually or with a qualified electronic signature) is the safest standard in property management.
Open-Ended Contracts vs. Fixed-Term Contracts
In principle, residential lease agreements in Germany are designed to be open-ended (for an indefinite period).
A fixed-term lease agreement (Zeitmietvertrag, with a fixed end date without the possibility of termination by the tenant) is only permissible under § 575 BGB if the landlord informs the tenant in writing of a specific, permissible reason for the limitation at the conclusion of the contract. Permissible reasons are:
- Personal Need: The landlord wants to use the apartment for themselves or their relatives after the time has elapsed.
- Reconstruction/Demolition: The building is to be fundamentally renovated, demolished, or newly built.
- Operational Need: The apartment is needed for a caretaker or employee (service apartment) after the end of the term.
If this justification is missing or invalidly advanced as a pretext, the contract legally transforms into an open-ended tenancy, which the tenant can terminate with the 3-month notice period.
Standard Clauses and Their Pitfalls
The majority of disputes before local courts in Lower Saxony (e.g., in Hanover or Braunschweig) result from invalid standard clauses in the contract.
1. Cosmetic Repairs (Schönheitsreparaturen)
According to the law (§ 535 BGB), the landlord is responsible for maintenance – thus also for painting work. However, they may pass this obligation on to the tenant, provided the apartment was handed over "renovated" upon moving in.
- Rigid deadlines are impermissible: Clauses such as "The kitchen and bathroom must compulsorily be painted every 3 years" make the entire transfer invalid. Soft formulations ("usually every x years, if necessary") are permitted.
- End renovation clauses: Clauses that flatly oblige tenants to always paint fresh white upon moving out (regardless of the actual condition of the walls) are invalid.
2. Minor Repair Clause (Kleinreparaturklausel)
The only real exception where tenants have to pay for repairs to the apartment's furnishings are minor repairs (dripping faucets, broken door handles). A valid clause must contain a double limitation:
- An absolute upper cost limit per individual case (customary in the industry approx. 100 to 120 euros).
- An upper cost limit for all minor repairs within one year (max. 8% of the annual cold rent or max. 300 - 400 euros per year).
3. Keeping of Pets
Clauses that strictly prohibit any keeping of pets are void (§ 307 BGB).
- Small animals (hamsters, ornamental fish) may not be prohibited at all.
- In the case of dogs and cats, a weighing of interests in the individual case is required; a reservation of permission ("only with the consent of the landlord") is permissible, but the consent may not be arbitrarily withheld.
4. Exclusion of the Right of Termination (Kündigungsverzicht)
Landlords and tenants can contractually agree on a mutual waiver of the ordinary right of termination. This waiver may not exceed a total duration of four years, starting from the conclusion of the contract until the date on which termination is first permitted. Longer waivers make the entire clause obsolete.
