Diritti e prime azioni

If the presence of a new building changes the rent or the conditions of the dwelling, it is important to know your rights as a tenant in Italy and take concrete actions. Residential leasing is governed by Law 431/1998 and the Civil Code; if in doubt about contractual clauses or rent variations, keep a copy of the contract and notify the landlord in writing of any change.[1]

  • Gather documents: copy of the contract, payment receipts and received communications.
  • Photograph and note any habitability issues or ongoing works.
  • Keep receipts and proof of payments made to the landlord.
  • Notify the landlord in writing of any changes and ask for clarifications.
Keep both digital and paper copies of all correspondence with the landlord.

Rent updates may follow ISTAT indices or territorial agreements: check if your contract provides for ISTAT adjustments and to what extent. In some cases the law and local agreements set different limits or methods for rent adjustments.

Do not accept verbal increases; always request written and documented confirmation.

For contract registration and use of the RLI Form, consult the official instructions of the Revenue Agency.[2] If you believe the increase is incorrect, consider the deadlines to contest and collect evidence before starting any appeal.

Come contestare un aumento o preservare il canone

First of all, speak with the landlord seeking an amicable solution. If that is not possible, follow these practical steps to prepare a formal dispute.

  • Prepare a file with contract, receipts, photos and all communications.
  • Send a written communication (registered mail or PEC) explaining the reason for the dispute.
  • If necessary, seek legal advice or turn to the competent Court for disputes.
Organized documentation often speeds up dispute resolution.
