After a modal verb, the infinitive stands alone without 'zu'.

Cultural Tip
In Germany, rental law (Mietrecht) gives tenants strong protection. According to § 535 BGB, the landlord must ensure the rented property is free from material and legal defects. Failure to fix major problems can lead to rent reduction, contract termination, or legal action. When speaking about these issues, a formal register is preferred, especially in written complaints.
