Lettre Avis D'Augmentation de Loyer Template for France

A Lettre Avis D'Augmentation de Loyer is a formal legal notice that landlords in France must send to tenants when increasing rent. This document ensures compliance with French rental law, which strictly regulates when and how rent can be increased. Under the Loi n° 89-462 du 6 juillet 1989, you can only increase rent once per year on the lease anniversary date, and only if your rental agreement contains an indexation clause.

When do you need this document?

You need to send this letter when you want to increase your tenant's rent based on the annual Indice de Référence des Loyers (IRL) published by INSEE. The letter must be sent before the lease anniversary date to give proper notice. You'll use this document whether you're a private landlord managing your own property or a property management company acting on behalf of owners. The letter is essential for both furnished and unfurnished rental properties, provided the lease contains the required indexation clause.

Key legal considerations

Your rent increase calculation must be based solely on the official IRL published quarterly by INSEE - you cannot use arbitrary percentage increases. The letter must include detailed calculations showing the old rent amount, the applicable IRL indices, and the precise new rent amount. You must clearly state the effective date of the increase, which cannot be before the lease anniversary date. The notice must be formal and written, as verbal notifications are not legally valid. If you fail to send this notice by the anniversary date, you forfeit your right to increase rent until the following year. Additionally, the increase cannot exceed the variation in the IRL between the current quarter and the same quarter from the previous year.

Legal requirements in France

Under Article L112-1 du Code monétaire et financier, all rent increases must be calculated using the IRL methodology. The letter must contain specific mandatory elements: your complete contact information as the landlord, the tenant's full details, the property address, the original lease date, and the detailed calculation formula. You must reference the specific IRL quarter and year used in your calculation. The Décret n°2017-1198 du 27 juillet 2017 governs the technical aspects of IRL application and calculation methods. For social housing or conventioned properties, additional restrictions under Article L411-1 du Code de la construction et de l'habitation may apply. The letter should be sent via registered mail with acknowledgment of receipt to create a legal paper trail and ensure proper notification timing.
