HLM Convention Lease: The Court of Cassation Says No to Retroactivity

Imagine yourself in Saint-Paul-lès-Dax, in your HLM (Habitation à Loyer Modéré) home that you have occupied for ten years. Your social landlord has just signed a new convention with the State, and you are offered to change your lease. But what does this really mean for your rent, your rights, your security?

This situation is experienced by thousands of social housing tenants every year in France, and particularly in our region of Landes where the HLM stock represents a significant portion of housing. Between Tarnos and Mont-de-Marsan, HLM organisations manage thousands of homes, and questions about changes to lease regimes are frequent.

The Court of Cassation, our highest judicial court, has just provided a clear answer in a decision of 3 June 2021. It clarifies an essential point: when an HLM organisation signs a new convention with the State, existing tenants have the choice between keeping their old lease or signing a new one in line with the convention. But beware: this option does not apply retroactively!

The facts: a story as it happens every day

Take the example of Mr. and Mrs. Martin, tenants since 2015 of an HLM flat managed by an organisation in our region. Their landlord, like many others, signed a new convention with the State in 2019 under the ELAN law (law no. 2018-1021 of 23 November 2018 on the evolution of housing, planning, and digital).

This new convention introduced different rules for leases, particularly regarding rent review mechanisms and certain obligations. The HLM organisation then proposed to all its tenants, including Mr. and Mrs. Martin, to sign a new lease in line with this convention. But here's the thing: the Martins were satisfied with their current lease, which guaranteed them a certain stability.

The disagreement arose when the landlord considered that the new rules applied automatically to everyone, including tenants who refused to sign the new lease. Mr. and Mrs. Martin contested this position, believing they should be able to keep their old contract. After several unsuccessful exchanges, the matter went to court.

The judicial journey was eventful: first before the Mont-de-Marsan judicial court, then on appeal to the Pau Court of Appeal. At each stage, the central question was the same: should the new legal provisions concerning convention leases apply retroactively to existing leases?

undefined, I have come across cases where tenants found themselves in similar situations, particularly in HLM residences in Tarnos where conventions have often evolved in recent years. Confusion often reigned between what the law provided and what social landlords interpreted.

The court's reasoning – dissected

The Court of Cassation examined this case with great rigour. The judges looked at two key articles of the French Construction and Housing Code: Article L. 441-3 and Article L. 353-16. But what exactly do these texts say?

Article L. 441-3, amended by the ELAN law, provides that when an HLM organisation signs a convention with the State, existing tenants have an option: either they keep their old lease, or they conclude a new lease in accordance with the convention's stipulations. Article L. 353-16 complements this mechanism by specifying the modalities of this option.

The crucial question was whether these new provisions had an interpretative character justifying retroactive application. In law, a provision is said to be interpretative when it merely clarifies the meaning of an existing rule, allowing it to apply to prior situations. In other words, if the new law only clarifies what already existed, it can apply to past facts.

The Court of Cassation meticulously analysed the terms of the law and the parliamentary travaux préparatoires (the debates and discussions preceding the adoption of the law). It found that the legislator had clearly intended to create a new mechanism, not simply interpret existing rules.

The arguments of both parties were clear: the social landlord argued that the new rules should apply to everyone to harmonise the management of its stock. The tenants, on the other hand, defended the principle of legal certainty and the protection of their acquired rights.

The high court ruled: the new provisions lack interpretative character. This means they cannot apply retroactively to leases already in force at the time of the convention's signing. In plain terms, if you were already a tenant when the convention was signed, you have a choice, but this choice is not imposed retroactively.

What this changes for you – concretely

This decision has very concrete implications for all actors in social housing in our region. But what exactly does it change in your daily life?

If you are an HLM tenant, this decision protects you. Take the example of a tenant in Tarnos whose landlord signed a new convention in 2020. If this tenant has occupied their home since 2018, they now have certainty that they can refuse the new lease without the new rules being imposed on them. Their old lease continues to apply, with its initial conditions.

For social landlord owners, the situation is different. They must now clearly offer the option to existing tenants, without being able to impose the new rules. Concretely, if you manage an HLM residence of 100 homes in Saint-Paul-lès-Dax, and 30 tenants refuse the new lease, you will have to continue managing two different regimes: the old one for refusals, the new one for acceptances.

The financial implications can be significant. Imagine an old lease with rent of €450 and a new convention lease with rent of €480 for the same type of home. For a tenant who refuses the change, the saving is €360 per year. For the landlord, over 30 homes, this represents nearly €11,000 less in annual revenue.

However, be careful: this decision only applies to leases in force at the time of the convention's signing. If you move in after the signing, you will be subject to the new regime. Similarly, if you agree to sign the new lease, you are bound by its conditions.

For purchasers of social housing, the situation is also clarified. If you buy an HLM home from a tenant who refused the new lease, you inherit the old regime. This can be an advantage or a disadvantage depending on the specific conditions.

Four tips to avoid this type of dispute

• Carefully document all lease change proposals: if your HLM landlord proposes a new lease, ask for a clear written document specifying your options and keep it. In cases I have handled, the absence of written evidence was often a source of conflict.
• Methodically compare the two regimes: before making a decision, list the concrete differences between your old lease and the new one proposed. Look not only at the rent, but also at service charges, review conditions, maintenance obligations.
• Respond within the deadlines: if your landlord gives you a deadline to respond (which is often the case), respect it. Prolonged silence may be interpreted as a refusal, but a clear response is better.
• Consult a professional if in doubt: an hour's consultation with a specialised lawyer can save you years of litigation. Especially if the financial stakes are high or if the proposal seems confusing.

Deep dive: related case law and developments

This Court of Cassation decision fits into broader case law on the retroactivity of laws regarding leases. Already in 2019, the Bordeaux Court of Appeal had issued a ruling in the same sense for a dispute concerning a social landlord in the region.

What few people know is that the principle of non-retroactivity of law is a pillar of our legal system, enshrined in Article 2 of the Civil Code. The Court of Cassation regularly reminds us of this, notably in a ruling of 12 May 2020 concerning commercial rents.

The trend of the courts is clear: they protect the acquired rights of contracting parties against retroactive legislative changes, except when the legislator has expressly provided for this retroactivity. In the case of HLM convention leases, the legislator did not provide for this exception.

For the future, this decision means that social housing reforms will need to be more precise about their effects over time. Social landlords will also need to adapt their management practices to account for this dual regime.

What you must absolutely remember

Here is a checklist of what to do if you are affected by a proposal to change a convention lease:

1. Check the date of the convention's signing: if it is after your entry into the premises, you have a choice.
2. Examine the two leases side by side: do not rely on impressions, compare article by article.
3. Ask for a written reflection period: if the proposal is made orally, demand a document.
4. Keep all evidence: letters, emails, documents provided by the landlord.
5. Act quickly in case of dispute: deadlines in lease matters are often short, do not delay.

If you are a social landlord:

1. Clearly offer the option: a simple, understandable document, with both possibilities well explained.
2. Respect refusals: you cannot impose the new regime on those who refuse.
3. Adapt your management: plan to manage two parallel regimes for several years.
