Rent reduction

Term from the field of Rental & Management

Rent Reduction - Rent reduction refers to the tenant’s legal right to reduce the rent if the rented property has a defect that significantly impairs its suitability for use as specified in the lease. The legal basis for this is Section 536 of the German Civil Code (BGB), according to which the reduction takes effect by operation of law and does not require the landlord’s consent.

Requirements and Procedure for Rent Reduction

For a rent reduction to be valid, there must first be a significant defect in the rental property. Significant means that the use of the apartment is noticeably impaired. Purely cosmetic minor issues or trivial defects do not justify a reduction. Furthermore, the defect must not have been known at the time of moving in: Anyone who accepts visible damage upon handover of the apartment cannot later claim it as grounds for a reduction (§ 536b BGB).

The tenant is obligated to notify the landlord of the defect without delay (notice of defect). This notification should be in writing and describe the defect in detail. Without a proper notice of defect, the tenant may lose their right to a rent reduction and may even become liable for damages if the damage worsens due to the failure to report it.

The amount of the rent reduction depends on the extent of the impairment. There are no legally prescribed rates, but courts have developed guidelines over decades. The rent reduction always applies to the gross rent, i.e., including utilities. Important for landlords: The rent reduction takes effect automatically. The tenant does not need to apply for it; however, in the event of a dispute, the tenant bears the burden of proof regarding the defect and its extent.

Common Defects and Reduction Rates

Among the most common reasons for a rent reduction are mold growth, noise pollution, heating failure, and water damage. In cases of mold infestation in living spaces, courts have recognized rent reduction rates ranging from 10 to 100 percent, depending on the extent of the problem. The decisive factor is the cause: If the mold was caused by structural defects, the reduction is justified. If the cause lies in the tenant’s ventilation practices, the claim is invalid.

In the event of a complete heating failure during the heating season, reductions of between 50 and 100 percent have been upheld by the courts. Construction noise from the neighborhood can justify reductions of 10 to 25 percent, depending on its intensity and duration. A malfunctioning elevator on higher floors was assessed at around 15 percent. A permanent water stain on the ceiling that does not significantly impair use justifies only minor reductions of 3 to 5 percent. In the event of a complete failure of the hot water supply, 10 to 20 percent was deemed appropriate.

Communicating the Rent Reduction Correctly

Although the rent reduction takes effect by law, we recommend that tenants notify the landlord of the intended reduction in writing. This provides clarity and documents that the tenant has not simply “forgotten” to pay, but is consciously exercising a legal right. The notice should describe the defect, refer to the previously submitted notice of defect, and specify the amount of the reduction. Alternatively, tenants can continue to pay the disputed amount under an express reservation, with the intention of reclaiming it upon confirmation of the entitlement. This approach is particularly advisable when the reduction rate is uncertain.

Practical Tip for Landlords in Nuremberg and Franconia

In the Nuremberg metropolitan area, we observe that mold problems in older existing buildings in the Südstadt, in Gostenhof, and in parts of Fürth particularly frequently lead to rent reductions. The dense development and the typical sandstone facades of old Franconian buildings contribute to moisture problems when insulation and ventilation do not meet current standards.

We recommend that landlords respond promptly to every notice of defect, document the defect, and take verifiable steps to resolve it. A professional move-in inspection report protects against unjustified claims for rent reductions. In the case of mold, it is important to clarify immediately whether the cause is structural or usage-related-a building inspector can usually assess this quickly. Solving the problem early limits the period of rent reduction and preserves the relationship of trust with the tenant. If there are uncertainties regarding the amount of the rent reduction, it is worth seeking advice from the Nuremberg Association of Homeowners and Landowners.

Frequently Asked Questions

Does the tenant have to give advance notice of the rent reduction?

No, according to Section 536 of the German Civil Code (BGB), the rent reduction takes effect automatically as soon as a significant defect exists and the landlord has been informed of it. The tenant is only required to report the defect without delay. Formal approval or prior notice is not required. However, we recommend that tenants notify the landlord of the intended reduction in writing to prevent disputes.

Can the landlord terminate the lease due to a rent reduction?

As long as the rent reduction is justified, it does not constitute grounds for termination. However, if the tenant reduces the rent unjustifiably or by an excessive amount, the withheld amounts may be considered rent arrears. If the arrears reach two months’ rent, the landlord may terminate the lease without notice. Courts therefore advise tenants to calculate the reduction carefully and, if necessary, to continue paying the disputed amount subject to reservation.

How long may the rent be reduced?

The rent reduction remains in effect for as long as the defect persists. As soon as the landlord has fully remedied the defect, the right to a reduction ceases as of the date the defect was remedied. The tenant is not entitled to retroactively reduce the rent for the period following the repair. However, the claim for a reduction remains valid for the duration of the existing defect and can also be asserted retroactively.

Can the tenant claim damages in addition to the rent reduction?

Yes, the rent reduction and the claim for damages under Section 536a of the German Civil Code (BGB) are not mutually exclusive. If the tenant has suffered specific damage as a result of the defect-such as furniture damaged by mold or water damage-they may claim this damage in addition to the rent reduction. The prerequisite is that the landlord was aware of the defect or should have been aware of it and failed to respond in a timely manner.
