§ 133

For individual tenancies covered by § 2, nr. 1-4, of the previously applicable law on private urban renewal, where the rent tribunal has determined the amount of rent that can legally be charged before the commencement of works, the tribunal shall decide, upon the landlord's request, whether the renovation costs are reasonable in relation to the achieved quality once the renovation is completed. The tribunal shall also determine whether the completed renovation works are included in the positive list established pursuant to § 2, of the previously applicable law on private urban renewal, and whether the rent increase calculated by the landlord complies with the provision in § 5 a of the previously applicable law on private urban renewal. The landlord's request to the rent tribunal must be accompanied by a renovation account detailing the incurred and documented expenses and rent increases distributed across the individual tenancies, certified by a registered or state-authorized auditor.
