Tenancy law in Northern Germany's second-largest state, Lower Saxony (Niedersachsen), is primarily based on the nationwide provisions of the German Civil Code (Bürgerliches Gesetzbuch - BGB). However, the state government has enacted specific tenancy regulations via the Niedersächsische Mieterschutzverordnung (last updated effective 1 January 2025), particularly concerning tight housing markets.
Key Regulations at a Glance
State-Specific Ordinances
The Lower Saxony Tenant Protection Ordinance (Niedersächsische Mieterschutzverordnung) implements major restrictions in 57 designated municipalities characterized by tight housing markets:
- Rent Brake (Mietpreisbremse): For new leases, the rent may not exceed the local comparative rent by more than 10% (§ 556d BGB).
- Reduced Rent Cap (Kappungsgrenze): For existing leases, the rent may only be increased by 15% within three years up to the local comparative rent, instead of the regular 20% (§ 558 Abs. 3 BGB).
- Notice Block (Kündigungssperrfrist): If a rental apartment is converted into a condominium and sold, the new owner is prohibited from terminating for personal need (Eigenbedarf) for a period of 5 years (§ 577a BGB in conjunction with Nds. MieterschutzVO).
Municipalities currently affected by this ordinance include Hanover, Braunschweig, Osnabrück, Göttingen, Oldenburg, Wolfsburg, Lüneburg, and various North Sea islands.

Eviction and Termination
Landlords in Lower Saxony always need a legitimate interest (§ 573 BGB) for a standard termination, such as:
- Personal Need (Eigenbedarf): The landlord needs the apartment for themselves, family members, or members of their household.
- Economic Exploitation: The continuation of the tenancy prevents the landlord from appropriate economic exploitation.
- Significant Breach of Duty: For example, persistent late payments or disturbance of the domestic peace.
The notice periods for landlords are generally staggered: 3 months (up to 5 years tenancy), 6 months (after 5 years), and 9 months (after 8 years). Note: For contracts concluded before September 1, 2001, a 12-month notice period may still apply after 10 years of tenancy if specifically stipulated in the contract (Art. 229 § 3 Abs. 10 EGBGB).
Termination without notice is only permissible if there are reasons, such as rent arrears of two months' rent. For residential disputes, the local Amtsgericht (District Court) has exclusive jurisdiction regardless of the amount in dispute (§ 23 No. 2a GVG).

Misappropriation Act
Under the Lower Saxony Misappropriation Act (NZwEWG), municipalities with housing shortages can issue statutes prohibiting the misappropriation of living space. This includes:
- Use for commercial purposes.
- Vacation rentals (typically restricted if exceeding 8-12 weeks per year).
- Prolonged vacancy (typically exceeding 6 months).
This particularly affects regions characterized by tourism, such as Norderney or Borkum, as well as university cities.
Disclosure and Information Obligations
Landlords must provide tenants with certain information, including a valid energy certificate and detailed information about the rent (if exceptions to the rent brake are claimed).
Read more in our guide on Required Disclosures.
Maintenance and Defects
The landlord is obligated to hand over and maintain the rented property in a condition suitable for contractual use. This includes, in particular, a functioning heating, electrical, and plumbing system. In the event of significant defects, such as heating failure in winter or mold infestation, the tenant has the right to a rent reduction.
Details can be found in the guide to Maintenance Obligations.
