Increased Reference Rent: Tenant Guide France

Rent setting, control & indexation (IRL) 3 min read · published September 11, 2025

As a tenant in France, understanding the increased reference rent mechanism protects your rights against rent hikes and lease renewal. This guide simply explains when a landlord can request a rent above the reference rent, how to check calculations (IRL index), what evidence to gather and what steps to take in case of dispute, including conciliation or recourse to the competent court. You will find practical examples, action templates to follow and tips to negotiate or contest an increase. The information takes into account the rules of the 1989 law and recent amendments to help you act with full knowledge of the facts.

What does "increased reference rent" mean?

The increased reference rent refers to an amount proposed by the landlord that exceeds the locally controlled reference rent. This increase must be justified by objective elements (works, additional services, local situation) and comply with national and local rules provided by the 1989 law and its updates.[1]

In most regions, tenants are entitled to basic habitability standards.

When can the landlord apply an increased rent?

  • Annual rent revision (rent) based on the IRL or a revision clause included in the lease.
  • Proposal of a higher rent for a new tenant (move-in) in rent-controlled areas when the previous rent is below the local cap.
  • Increase following improvement or renovation works that justify a higher rental value (repair).
Always check the written justification for the increase before accepting it.

How to contest an increase?

If you consider the increase unjustified, start by requesting written explanations from the landlord and ask for supporting documents (work invoices, breakdown of services). Keep all exchanges and evidence: letters, photos, quotes and inventory of fixtures. If discussions fail, propose mediation or seize the departmental conciliation commission, and finally the judicial court.

  • Contact the landlord in writing and keep proof of receipt.
  • Gather evidence: photos, quotes, invoices and the inventory of fixtures.
  • Refer the case to the departmental conciliation commission or to the court if necessary.
Accurately documenting the condition of the dwelling increases your chances of success in conciliation or before a judge.

FAQ

Can a landlord increase the rent whenever they want?
No. Increases must respect the lease clauses, the IRL for annual revisions and local rent control rules.
What should I do if I receive a too-high rent proposal?
Request supporting documents, propose conciliation and, if needed, refer the matter to the departmental conciliation commission and then the judicial court.
Are works alone enough to raise the rent?
Not automatically. Works must be justified and result in a durable improvement or additional services to justify an increase.

How-To

  1. Check the lease and the revision clause to know the applicable conditions.
  2. Calculate the possible increase by applying the IRL published by INSEE (rent).
  3. Contact the landlord in writing and request all supporting documents.
  4. Refer the case to the departmental conciliation commission and then to the judicial court as a last resort.

Key takeaways

  • Keep all documents and written exchanges safe.
  • Respect deadlines to respond to the landlord's notifications.
