HLM and Common Law Leases: When a Change of Owner Modifies Your Rights

Imagine yourself in Antibes, in your apartment with a sea view, having been a tenant for ten years under a common law lease (that is, a standard lease, not subject to specific rules like those for HLM). Your landlord decides to sell, and it's a low-rent housing organisation (HLM) that purchases the building. What becomes of your lease? Do you continue to benefit from the same conditions, or do you automatically switch to the HLM regime, with its specific constraints and advantages?

This question, much more common than one might imagine, arises regularly in our region where the property market is dynamic. In Mougins as in Antibes, transactions between private owners and HLM organisations are not rare, particularly for older buildings or co-ownership properties. Every owner, every concerned tenant then wonders: do my rights change overnight?

The Court of Cassation provided a clear answer in its decision of 28 May 2020. This case law (the body of judicial decisions that carry authority) clarifies the exact moment when the change of legal regime applies. But what exactly does this change mean for you, as an owner, tenant, or property professional? This is what we will analyse together.

The facts: a story that happens every day

Ms R., whom we'll call Sophie for ease of understanding, had been a tenant of an apartment in Nice for several years. Her lease was a common law residential lease, that is, governed by the 1989 law, with a rent freely agreed with her landlord, Mr Dupont. Their relationship was peaceful, the rents were paid regularly, and Sophie appreciated her accommodation.

In 2017, Mr Dupont decided to sell his building. He found a buyer in the form of a low-rent housing organisation (HLM), the Société Immobilière Côte d'Azur. The sale was concluded, and the HLM organisation became the new owner. Immediately, the company notified Sophie that her lease was now subject to the HLM regime, with all the consequences that this entails: rent capping, specific revision rules, different termination conditions.

Sophie contested this position. She believed that her lease, concluded under the common law regime, should continue to apply until its term, in accordance with the principle "the lease survives the sale". In other words, the new owner must respect the initial conditions. She therefore refused to sign a new HLM lease and continued to pay her initial rent.

The HLM organisation then initiated proceedings to have the application of the HLM regime recognised. The tribunal d'instance (court with jurisdiction over tenancy disputes) ruled in Sophie's favour at first instance. But the HLM organisation appealed, and the cour d'appel reversed the decision. Sophie, determined, appealed to the Court of Cassation (she referred the matter to the Court of Cassation to challenge the application of the law by the lower courts). It is this final stage that led to the decision we are analysing today.

The court's reasoning — analysed

The Court of Cassation had to decide a technical but crucial question: at what exact moment does the change of owner trigger the change of legal regime for the lease? The supreme judges relied on Article L. 351-2 of the Code de la Construction et de l'Habitation (CCH), which specifically governs conventional HLM leases.

In clear terms, Article L. 351-2 CCH provides that when a property is owned by an HLM organisation and is subject to a specific agreement with the State, it is subject to a particular regime. But what about properties acquired by an HLM that are not covered by such an agreement? This is precisely Sophie's case: her property was purchased by an HLM, but without an L. 351-2 agreement.

The Court analysed the arguments of both parties. The HLM organisation maintained that from the acquisition onwards, all leases should switch to the HLM regime, because the owner's status determines the applicable regime. Sophie, on the other hand, argued that her common law lease should survive with its initial conditions until its expiration.

The judges adopted a nuanced position. They recalled the fundamental principle: in case of sale of a leased property, the lease continues with the new owner (this is called "survival of the lease"). But they specified that when the new owner is an HLM organisation, and the property is not covered by an agreement, the provisions governing HLM leases apply... but only from the renewal of the lease onwards.

Note however: renewal here does not mean signing a new contract. It refers to the moment when the initial lease reaches its term and is tacitly renewed (that is, automatically, without a new deed). For Sophie, this means that during the remaining duration of her initial lease (for example, until the end of the three-year period), she retains her common law regime. It is only at the first tacit renewal that the HLM regime will apply.

This reasoning constitutes confirmation of previous case law. The Court of Cassation maintains a balanced position: it protects the tenant's stability during the initially agreed duration, while allowing the new HLM owner to apply its specific regime in the medium term. undefined, I have encountered cases where this distinction between acquisition and renewal created significant legal uncertainty for both parties. This decision therefore provides welcome clarification.

What this changes for you — concretely

If you are a landlord in Mougins and are considering selling to an HLM organisation, you should know that your tenants do not immediately switch to the HLM regime. Their current leases continue to apply until their term. This may influence your negotiation: the HLM purchaser knows they will have to wait for renewal to apply their capped rates.

If you are a tenant like Sophie, in an apartment in Antibes for example, this decision protects you. Imagine you pay €1,200 per month for a three-room apartment with a terrace. Your landlord sells to an HLM. Thanks to this case law, you keep your rent of €1,200 until the end of your initial lease. At renewal, the HLM can apply a capped rent according to the HLM scale, which might be €850 for the same property. You therefore gain several months, or even years, of stability.

If you are a purchaser, particularly an HLM organisation, you must integrate this delay into your financial planning. You will not immediately have complete control over rents. In co-ownership properties, this situation can create disparities between properties still under common law regime and those already under HLM regime, complicating management.

For property professionals (agents, notaries), this decision requires clear information to be provided to the parties. When selling to an HLM, it is necessary to specify in the sale deed or annexes that the current leases remain governed by common law until their renewal. What few people know is that this transition period can last up to three years (typical duration of a lease), or even longer in case of successive renewals.

How to react if you are affected? First, check the renewal date of your lease. Then, anticipate the change of regime: find out about the HLM rent caps applicable in your municipality. In Antibes, for example, caps vary according to neighbourhoods and surface area. Finally, keep your initial lease and all exchanges with the landlord carefully.

Four tips to avoid this type of dispute

• Systematically check the new owner's status: as soon as you learn of a sale, ask the seller or purchaser in writing whether the latter is an HLM organisation. This information should appear in the notice of sale that you receive as a tenant.
• Have a joint inventory drawn up: before the sale, insist on a detailed inventory with the outgoing owner and, if possible, the incoming one. This avoids subsequent disputes about the property's condition when the regime changes.
• Keep a certified copy of your initial lease: in case of dispute, this is your key document. If you only have a simple copy, have it certified by a bailiff or your solicitor. undefined, I have seen cases fail due to lack of proof of the exact lease content.
• Negotiate a transition clause in the sale deed: if you are a seller, propose to the HLM purchaser to insert a clause specifying the exact renewal date of the leases and the transition arrangements. This secures the transaction for everyone.

Further analysis: related case law and developments

This decision fits into a coherent line of case law. Already in 2015, the Court of Cassation (judgment No. 14-10.305) had considered that HLM provisions did not apply retroactively to ongoing leases. It thus confirms an approach protective of tenants' acquired rights.

However, an earlier decision from 2012 (No. 11-10.028) had sown doubt by seeming to allow immediate application of the HLM regime. The 2020 decision therefore clarifies and reinforces the majority position: no, the change is not immediate, it occurs at renewal.

What this means for the future? Courts should apply this rule uniformly. For tenants, this is enhanced security. For HLM organisations, this implies better planning of their acquisitions taking this latency period into account. The trend is towards balance between tenant protection and the necessary adaptation of the housing stock to social rules.

In other words, if you are in a similar situation, you can rely on this decision with relative confidence. But be careful: each case has its specificities, particularly concerning the exact renewal date, which can be a source of dispute.

Frequently asked questions

Q: My landlord has just sold to an HLM, do I need to sign a new lease immediately?
A: No. Your current lease remains valid until its term. You should not sign any new document before the tacit renewal.

Q: How do I know if my property is covered by an L. 351-2 agreement?
A: Request a copy of the agreement from your landlord (former or new). It should be annexed to the lease. In its absence, presume that the property is not covered by an agreement.

Q: Can I contest the new HLM rent at renewal?
A: Yes, but only regarding the calculation. You can verify that the proposed rent respects the legal caps for your municipality and your property's surface area.

Q: What happens if I move before renewal?
A: The lease ends normally. The new tenant will sign an HLM lease directly, without a transition period.

Q: Does this rule also apply to commercial leases?
A: No, this decision concerns only residential leases. Commercial leases follow different rules, often more favourable to the tenant in case of sale.
