These disputes fall under the exclusive jurisdiction of the local court (Amtsgericht), and violations can result in damage claims, administrative fines, or the invalidity of certain contract clauses.

Overview of Disclosure Requirements
Energy Performance Certificate
The energy certificate is mandatory under § 87 of the Building Energy Act (GEG). Landlords must provide energy information to tenants to ensure transparency regarding the property's energy performance.
Rent Cap Disclosures
In municipalities where the rent cap (Mietpreisbremse) applies under § 556d BGB, the rent at the start of the lease may not exceed the local comparable rent by more than 10 percent. Landlords must ensure they comply with these limits in designated areas with tight housing markets.
Operating Cost Statement
If operating cost prepayments are agreed, the landlord must issue an annual statement:
- Billing period: Typically 1 year (calendar or fiscal year)
- Deadline: 12 months after the end of the billing period (§ 556(3) BGB)
- Missed deadline: The landlord is generally barred from claiming additional payments if the deadline is missed, unless they are not responsible for the delay. The tenant retains their right to a refund of any overpayments.
CO₂ Cost Allocation (Since 2023)
Since January 1, 2023, the CO₂ Cost Allocation Act (CO2KostAufG) requires CO₂ costs from heating fuel to be shared between landlord and tenant. The allocation is determined by a tiered model based on the building's energy efficiency and specific CO₂ emissions. The landlord must break down these costs annually alongside the operating cost statement.
Best Practices for Landlords
- Issue operating cost statements on time and in full.
- Factor the CO₂ allocation into your operating cost calculations from the start.
- Maintain current documentation regarding the property's energy performance.
