Berlin Landlord-Tenant Laws: Complete Guide for Property Owners

Berlin is one of the most heavily regulated rental markets in Germany. Primary residential tenancy regulations are governed by the German Civil Code (BGB), which came into effect on 1 January 1900. Whether you manage a single apartment or multiple residential buildings, understanding the applicable regulations—including state-level ordinances specific to Berlin—is essential for legally compliant property management.

Key Berlin Rental Laws at a Glance

Security Deposits

The security deposit (Kaution) may not exceed three months' net cold rent (rent excluding utilities and operating costs). Tenants have the legal right to pay the deposit in three equal monthly installments. The first installment is due at the start of the tenancy.

The landlord must invest the deposit separately from their own assets in an insolvency-proof, interest-bearing account. Any accrued interest belongs to the tenant.

After the end of the tenancy, the landlord generally has 3 to 6 months to return the deposit, or up to 12 months in complex cases with pending utility bills.

Rent Control and Increases

Berlin is classified as a housing market with "tight housing supply." The rent control mechanism (Mietpreisbremse), governed by BGB §§ 556d et seq. and the Berlin Mietbegrenzungsverordnung, has been extended until December 31, 2029:

• New Leases: Rent may not exceed the local comparative rent (based on the Berlin Rent Index / Mietspiegel) by more than 10%.
• Exemptions: New buildings (first occupied after Oct 1, 2014) and comprehensively modernized apartments.
• Rent Increase Cap (Kappungsgrenze): Under BGB § 558 (3) and the Berlin Kappungsgrenzen-Verordnung, rent increases for existing tenancies are capped at 15% within a three-year period across the entire city, effective until May 10, 2028.
• Rent increases must be justified (e.g., via the Rent Index, an expert opinion, or three comparable apartments).

Eviction Procedures

Germany offers strong eviction protections (Kündigungsschutz) for tenants. Landlords can only terminate a lease for legally recognized reasons:

Ordinary Termination (Ordentliche Kündigung)

• Personal Use (Eigenbedarf): Landlord needs the apartment for themselves or close family members.
• Economic Exploitation: Continuing the lease would prevent reasonable economic exploitation of the property.
• Substantial Breach of Contract: Repeated lease violations by the tenant.

Immediate Termination (Fristlose Kündigung)

• Rent arrears of two consecutive months or a significant outstanding balance.
• Severe lease violations (e.g., unauthorized subletting, disturbing the peace).

Notice Periods

Berlin Specificity: Under the Kündigungssperrfristverordnung, when rental apartments are converted into condominiums, a 10-year blocking period prevents the new owner from evicting tenants for personal use (Eigenbedarf).

Required Disclosures Berlin

landlords must provide several pieces of information to tenants:

1. Energy Certificate (Energieausweis) - Disclosure is governed by the Building Energy Act (Gebäudeenergiegesetz - GEG). Per § 80 (4) GEG, the landlord or agent must present the energy certificate to potential tenants at the latest during the property viewing.
2. Previous Rent / Rent Control Info - must be disclosed unprompted if claiming an exemption to the rent brake.
3. Operating Costs - detailed annual utility reconciliation.
4. Cosmetic Repairs - clear contractual terms regarding tenant obligations.
5. House Rules (Hausordnung) - rules for living in the building.
6. Living Area Calculation (Wohnflächenberechnung) - accurate square meterage.

For more detail, see our Required DisclosuresPreview unavailable guide.

Maintenance and Habitability

According to BGB § 535 (1), the landlord is obliged to maintain the rental property in a condition suitable for the contractually agreed use. This includes:

• Functional heating and hot water (minimum temperatures apply in winter).
• Weatherproof windows and doors.
• Intact sanitary facilities and electrical wiring.
• Safe drinking water and proper sewage disposal.
• Freedom from mold (if structurally caused).
• Working smoke detectors (mandatory in Berlin since 2017).

If defects occur, the tenant can claim a rent reduction (Mietminderung) until the issue is fixed.

For more detail, see our Maintenance ObligationsPreview unavailable guide.

Late Fees and Default Interest

German law does not allow for arbitrary fixed "late fees" as seen in other countries. Instead:

• Once in default (usually after the 3rd business day of the month), the landlord can charge default interest (Verzugszinsen).
• The statutory default interest rate is 5 percentage points above the base interest rate (BGB § 288).
• Contractually agreed reminder fees (Mahnpauschalen) must be reasonable (typically around €2.50 to €5.00).
• Excessive penalty fees in standard contracts are considered invalid.

For more detail, see our Late FeesPreview unavailable guide.

Local Ordinances and Specialties

Berlin has additional regulations that go beyond federal law:

• Conversion Permit Requirement: Under § 250 BauGB and the Berlin Umwandlungsverordnung (Conversion Ordinance), the conversion of rental apartments into condominiums in buildings with more than five apartments is subject to a strict permit requirement throughout the entire city of Berlin. This regulation is currently effective until December 31, 2030.
• Social Preservation Areas (Milieuschutzgebiete): Specific districts with additional protections against structural changes that could displace the local population.
• Misappropriation Ban (Zweckentfremdungsverbot): Strict permit requirements for short-term holiday rentals (e.g., Airbnb) and keeping apartments vacant.
• 10-Year Eviction Block for personal use after condo conversion under the Kündigungssperrfristverordnung.
