Is it permissible for the tenant to recover the costs of renovating the apartment from the landlord or the new tenant?

The landlord is obligated to repair the property to make it fit for use. If he refuses to carry out the repairs, the tenant has the option to terminate the contract, provided he did not initially accept the defect. If the tenant repairs something without the landlord's request, he is not entitled to be reimbursed for what he spent because he acted as a volunteer. However, if the repair was at the landlord's request or by agreement with the landlord, he is entitled to be reimbursed and can reclaim the cost from the landlord. The tenant does not have the right to claim repair costs from the new tenant, as the new tenant rents the property in its current condition and is not obligated to pay for previous expenses incurred on it.
