Normative Context: The Narcotraffic Law of January 24, 2026
Law No. 2026-56 of January 24, 2026 on the fight against drug trafficking has profoundly modified the rules applicable to the eviction of tenants of social housing involved in drug trafficking activities. This text, which came into force on March 1, 2026, is part of a legislative movement aimed at strengthening the prerogatives of social landlords faced with the exploitation of HLM housing as a base for criminal networks. Article 12 of this law inserted a new article L. 442-6-1 in the Code de la construction et de l'habitation (CCH) (Construction and Housing Code), creating a specific ground for automatic termination of the lease for serious fault.
Analysis of the Texts: A Regime Derogating from Common Law
Article L. 442-6-1 CCH provides that "the lease of social rental housing may be terminated automatically when the tenant, their spouse, their cohabiting partner, or an occupant under their authority engages in activities of illicit production, transport, possession, or sale of narcotics in the dwelling or its immediate surroundings". This mechanism derogates from the common law of judicial termination provided for in Article 1728 of the Code civil (Civil Code) and the standard procedure for termination for reasons of general interest (Article L. 442-6 CCH).
The legislator specified that the finding of these facts may result from:
- a final criminal conviction for an offense under drug legislation (Articles 222-34 to 222-43 of the Code pénal (Penal Code));
- or a police or gendarmerie report drawn up in the context of a preliminary or flagrante delicto investigation, provided it mentions sufficiently detailed elements.
Decree No. 2026-234 of March 15, 2026, issued for the application of this law, set the notification procedures for the termination: the social landlord must send the tenant a registered letter with acknowledgment of receipt mentioning the alleged facts, the reference to the report or conviction, and the voluntary departure period of two months. Failing vacating the premises within this period, the landlord may refer the matter to the juge de l'exécution (enforcement judge) for eviction, without having to first obtain a judicial decision finding the termination of the lease.
Practical Issues for Professionals
The Burden of Proof
The central question lies in the administration of proof. While a final criminal conviction constitutes irrefutable proof, recourse to the sole investigation report raises difficulties. The enforcement judge, seized of the eviction request, must verify the formal regularity of the report and the existence of serious, precise, and consistent indications establishing the tenant's participation in the trafficking facts. Recent case law of the Cour de cassation (Court of Cassation) (Civ. 3e, March 12, 2026, No. 25-10.456) specified that the report must be "detailed and unambiguous", failing which the judge may order a supplementary investigative measure.
Tenant Remedies
The tenant has several avenues of recourse. They may contest the termination before the enforcement judge within the framework of the eviction procedure, invoking in particular:
- the lack of sufficient proof of the facts;
- the irregularity of the notification (deadline, mandatory information);
- the violation of the adversarial principle.
Furthermore, Article L. 442-6-1 CCH provides an exception for tenants in good faith who demonstrate that they were unaware of the actions of the occupants under their authority. This exception, strictly interpreted by the judges, requires the tenant to provide proof of their ignorance and the absence of any negligence.
The Fate of Occupants
Termination of the lease entails the eviction of all occupants of the dwelling, including the tenant's family members, unless they justify a separate occupancy title. However, the social landlord must respect the winter truce (Article L. 412-6 of the Code des procédures civiles d'exécution (Code of Civil Enforcement Procedures)), unless the judge orders an eviction without delay due to the seriousness of the facts.
Perspectives and Criticisms
This new mechanism sparks debate within legal doctrine. On one hand, it responds to a practical need to combat the hold of criminal networks on the social housing stock, which undermines the tranquility of other tenants and degrades the image of neighborhoods. On the other hand, voices are raised to denounce a risk of arbitrariness, particularly due to the possibility of termination based on a simple report, without prior judicial control. The Conseil constitutionnel (Constitutional Council), in its decision No. 2025-832 DC of December 15, 2025, validated the mechanism subject to the enforcement judge exercising effective control over the regularity of the procedure and the proportionality of the measure.
In practice, social landlords must be particularly vigilant in preparing files: the report must be accompanied by a detailed account from the investigating service, and the notification must strictly comply with the forms prescribed by the decree. Lawyers acting for tenants will have an interest in systematically challenging the probative value of reports not corroborated by other elements (testimonies, surveillance, seizures).
In the future, a legislative evaluation is planned for 2028, which could lead to an adjustment of the text, particularly to more strictly regulate the use of reports as sole evidence. In the meantime, professionals must integrate this new development into their daily practice.
