What to do if your landlord is renting illegally: your rights as a tenant

A black rental refers to a housing arrangement where the owner does not declare rental income to the tax authorities. The lease may exist on paper or be purely verbal, rents are sometimes paid in cash, and there is no record that reaches the administration. This situation exposes the landlord to sanctions, but it also weakens the tenant on several fronts, particularly regarding housing assistance and proof of payments.

Loss of APL and CAF blockage: the tenant pays for the owner’s fraud

The first concrete effect of an undeclared rental hits the tenant’s wallet long before it affects the landlord’s. The CAF can suspend housing assistance in the absence of an annual rent declaration by the owner. In other words, a tenant who regularly pays their rent may lose their APL or ALS because the landlord has never provided the required information.

The tenant is not legally responsible for the tax fraud of their landlord. They have no obligation to verify that rental income is declared. Understanding the rights of the tenant in the case of a black rental helps to better anticipate these administrative blockages and know how to react to the CAF.

In practice, when the CAF requests a rent certificate from the landlord and they do not respond, the assistance is suspended or recalculated. The tenant must then follow up with their landlord in writing, preferably by registered mail, reminding them that this certificate is necessary for the payment of assistance.

Verbal lease and cash payment: building solid evidence

Many black rentals operate without a written contract, with rents paid hand-to-hand. This lack of written record does not mean that the tenant is without recourse. French law recognizes verbal leases, but one must still be able to prove the rental relationship and the amounts paid.

What evidence to gather

  • Bank transfers or account statements showing regular payments to the landlord, even partial ones, constitute the strongest evidence
  • Exchanges of SMS, emails, or messages on a messaging app where the landlord mentions the rent, keys, or the property
  • Rent receipts, even handwritten, or any signed receipt from the landlord confirming a cash payment
  • Testimonies from neighbors or acquaintances who can confirm the occupation of the property and regular payments

The legal cash payment limit between individuals is set at 1,000 euros. A rent paid in cash beyond this threshold weakens the landlord’s position in case of a dispute. The tenant has every interest in documenting each payment, even with a simple photo of the receipt.

Declaration of occupants on impots.gouv.fr: what changes for the tenant

The General Directorate of Public Finances now requires owners to declare the occupants of their properties on impots.gouv.fr. This obligation, distinct from the declaration of rental income, aims to precisely identify who occupies each housing unit.

For a tenant in a black rental situation, this development has a direct consequence. An owner who does not declare their occupants exposes themselves to a tax audit that can trace back to the undeclared lease. The tenant, however, has no steps to take on this aspect, but they can report the anomaly to the administration if they notice that their housing does not appear in the tax databases.

This data cross-referencing mechanism makes it more difficult to maintain a black rental over time. An owner whose property is listed in the land registry but without a declared occupant attracts the attention of the tax authorities.

Tenant recourse: conciliation, justice, and reporting

Faced with a landlord who rents illegally, the tenant has several levers. The goal is not to replace the tax administration but to protect their own rights, particularly the return of the security deposit, obtaining receipts, and maintaining housing assistance.

The amicable route first

A registered letter with acknowledgment of receipt remains the first step. It should remind the landlord of their obligations: to provide rent receipts, send the certificate to the CAF, and comply with the terms of the lease (even verbal). This letter creates a dated record that can be used in any subsequent proceedings.

Contact the departmental conciliation commission

If the letter goes unanswered, the departmental conciliation commission can be contacted for free. This body handles rental disputes concerning rent, security deposits, inventory, and charges. The process is quicker than going to court.

The judicial court as a last resort

For a dispute that exceeds the amicable phase, the judicial court is competent. A conciliator (free of charge) can also intervene beforehand. The tenant can request the return of their security deposit, payment of damages in case of harm, or the regularization of the lease.

Report the situation to the tax authorities or the town hall

The tenant can report the undeclared rental to the tax authorities, especially if the landlord refuses to regularize the situation after several reminders. This report does not constitute a criminal denunciation but rather information passed to the administration that will decide on the next steps.

Some municipalities have a rental permit that is mandatory in areas defined by prefectural order. A landlord who rents without this permit is subject to specific fines. The tenant can check with their town hall if their housing is located in an area subject to this obligation.

A black rental does not absolve the landlord of their obligations regarding the decency of the housing, safety, and maintenance. An undeclared lease remains a lease under civil law. Therefore, the tenant retains all their rights, including the right to request compliance work or contest an irregular notice.
