Rent reduction (Mietminderung)

If a defect impairs the usability of the rented property, the tenant is entitled to a reduction by operation of law — regardless of any fault on the landlord's part. The defect must have been reported. The amount of the reduction depends on the impairment (e.g. mould 10–20 %, heating failure in winter up to 100 %).
