📋 Mandatory legal rules

RULE 1:

A revision clause must be included in your lease to be able to revise the rent.

RULE 2:

The revision can only take place once a year, on the date specified in the lease (anniversary date).

RULE 3:

The IRL of the lease reference quarter and the latest published IRL at the time of revision are used.

⛔ PROHIBITED:

Revising the rent of a property rated F or G on the DPE

  • Mainland France: prohibited since 24/08/2022
  • Overseas territories: prohibited since 01/07/2024
⚖️ ALUR LAW:

No catch-up of past revisions

If you have not revised the rent for several years, intermediate year revisions are permanently lost and cannot be recovered.

The revision applies only from the request date, not retroactively.

💡 Example:

Lease signed in 2020, revision request in 2025 → The increase applies from 2025, but you cannot claim rent differences from 2021 to 2024.

Frequently asked questions

When can rent be revised?

Rent revision can only occur once a year, on the date specified in the lease (usually the anniversary date). A revision clause must be included in the lease.

Which IRL should be used?

Use the IRL of the reference quarter indicated in the lease (usually the quarter of the signing month) and the latest IRL published by INSEE at the time of revision. The IRL must be officially published to be applicable.

What is the difference between IRL, ILC and ILAT?

The IRL (Rent Reference Index) applies to residential leases. The ILC (Commercial Rent Index) applies to commercial leases. The ILAT (Tertiary Activities Rent Index) applies to professional leases (offices). This calculator only handles the IRL (residential).

Can rent be revised for F or G rated properties (DPE)?

No, since August 24, 2022 in mainland France, and since July 1, 2024 in overseas territories, it is forbidden to revise rent for F or G rated properties. Since January 2025, G-rated properties can no longer be rented out. F-rated will follow in 2028, and E-rated in 2034.

Is the rent shield (3.5% cap) still in effect?

No. The "bouclier loyer" that capped IRL increases at 3.5% in mainland France ended definitively on March 31, 2024. Since Q2 2024, the IRL applies without any cap. In practice, current IRL variations (around 1%) are well below the former cap.

Can the IRL decrease?

Yes, the IRL can decrease. If your lease contains a revision clause, it generally applies in both directions (increase and decrease). Case law tends to consider the clause applies automatically, but check the exact wording of your lease.

What if the lease doesn't include a revision clause?

Without a revision clause, the rent remains fixed for the entire contract duration. The landlord cannot impose a revision. A clause can be added when renewing the lease with tenant's agreement.

What is the "complément de loyer" (rent supplement)?

In rent-controlled areas (Paris, Lyon, Lille, etc.), landlords can apply a rent supplement for exceptional characteristics (view, terrace, etc.). This supplement is NOT subject to IRL revision — only the base rent is revised annually.

How should the tenant be notified of the revision?

The landlord must notify the tenant in writing: registered letter with acknowledgment of receipt, bailiff notice, or hand delivery with signed receipt. A simple email, SMS, or regular mail has no legal value.

What happens if the landlord forgets to revise the rent?

Since the ALUR law (2014), the landlord has one year from the anniversary date to request the revision. If they act within this period but late, the increase only applies from the request date (not retroactively). After 1 year, the revision is permanently lost.

How to contest a rent revision?

The tenant can contest by contacting the free departmental conciliation commission (CDC), then possibly the court. They have a 3-year limitation period to claim overpayments (Article 7-1 of the law of July 6, 1989).

Is there a cap on increases in tight zones?

The "bouclier loyer" (3.5% cap) ended in March 2024. However, rent control remains in effect in certain cities (Paris, Lyon, Lille, Montpellier, Bordeaux, etc.) and has been extended until July 31, 2026. In these areas, the base rent cannot exceed the increased reference rent set by the prefecture.
