Rent updates (ISTAT) and local agreements (with attestation) 3 min read · published September 11, 2025

If you live in a rented property under a temporary lease in Italy, understanding the contract conditions is essential to protect your rights as a tenant. This article clearly explains how rent is determined, how ISTAT adjustments work and when territorial agreements or specific arrangements between parties may apply. You will find practical guidance on contract registration, the option for cedolare secca, how to respond to a request for an increase and which documents to collect in case of a dispute. The information is aimed at those who are not legal experts and includes references to official sources to deepen the administrative and procedural steps.

Main conditions of the temporary lease

A temporary lease contract sets duration and rent for motivated temporary needs. The rent can be freely agreed between the parties, but often includes an adjustment clause linked to ISTAT or to territorial agreements that modify increases.[1] Contract registration with the Italian Revenue Agency is mandatory for contracts longer than 30 days in a year and requires the use of the RLI form.[2]

Always keep signed copies and payment receipts for at least five years.

What to check immediately in the contract

  • Rent (rent) and payment methods (payment): amount, due dates and receipts.
  • ISTAT adjustment (within): clauses that indicate when and how often the adjustment applies.
  • Territorial agreements or written clauses (form): check for any local agreements or reference tables.
  • Security deposit (deposit): amount, return conditions and possible deductions.

Tenants' rights and duties

As a tenant you have the duty to pay the agreed rent and the right to housing in habitable conditions. The landlord must guarantee ordinary and extraordinary maintenance depending on the agreements and the nature of the fault. If habitability problems arise, document them with photos and written communications.

In many regions, national rules are integrated by local agreements that affect rent increases.
  • Repairs and maintenance (repair): report faults in writing and keep receipts of reports.
  • Privacy and access (entry): the landlord must agree inspections and visits with notice.
  • Payments and receipts (payment): keep receipts for every payment and use traceable methods where possible.

When to dispute an increase or an ISTAT adjustment

If you receive a request for an increase based on an ISTAT adjustment or a territorial agreement, verify the contractual clause and the calculations: the text must indicate the percentage, the calculation basis and the periodicity. If in doubt, send a written dispute to the landlord and attach documentation (receipts, contracts, photos). If the dispute is not resolved, consider the support of a tenant association or legal action before the Civil Court.

Always reply within the indicated deadlines to avoid losing procedural rights.

FAQ

What is the ISTAT adjustment and how does it apply to rent?
The ISTAT adjustment adjusts the rent to inflation according to an official index; the contract must include the clause and indicate methods and periodicity.

Yes, registration with the Italian Revenue Agency is mandatory for contracts whose duration exceeds 30 days in a year and is carried out with the RLI form.
