A tenant who houses his brother after a separation, a mother who takes in her student daughter, a friend who helps out an unemployed relative: life brings people into the rented dwelling. And with them, a question that causes friction: does the landlord need to be informed? Should consent be sought? Risk termination of the lease?
The topic is tricky because it touches on two principles that stare each other down: the tenant's freedom to use the dwelling as they see fit, and the landlord's right to know who actually lives in their property. Between the two, case law has drawn a line that many discover too late.
The 30-Second Answer
A tenant may house a relative free of charge without the landlord's consent, provided that the accommodation remains free and does not amount to disguised subletting. The law of 6 July 1989 does not subject free accommodation to the owner's authorization. However, if the relative pays a financial consideration, even a modest one, or if the tenant leaves the premises leaving the dwelling to the relative, it becomes subletting, which requires the landlord's written consent.
The real risk is therefore not the accommodation itself, but its legal classification. A landlord who discovers an undeclared occupancy may attempt to terminate the lease by invoking unlawful subletting. It is up to you to prove that the accommodation was free.

What the Law Says
Article 7 of Law No. 89-462 of 6 July 1989 requires the tenant to use the rented premises peacefully and to respect the purpose of the dwelling. It nowhere mentions a prohibition on housing a relative. The silence of the law here is a right: what is not prohibited is permitted.
Article 8 of the same law governs subletting. It provides that the tenant may only sublet the dwelling with the landlord's written consent, including as to the rent amount. Subletting is defined as making the dwelling available to a third party in exchange for consideration, usually financial.
The distinction is therefore simple in theory:
- Free accommodation: no consideration, no consent required.
- Subletting: financial or in-kind consideration, written consent mandatory.
But practice loves to blur the lines. A relative who contributes to expenses, who pays part of the rent "to help out," who occupies the dwelling while the tenant is away for several months: all situations where the gratuity becomes questionable.
Why This Can Be a Problem
The landlord does not need to know the identity of every person who sleeps under their roof. But they have a legitimate interest in knowing whether the dwelling is still occupied by the tenant named in the lease, and whether the tenant has derived unlawful profit from it.
Three situations concentrate disputes:
1. Financial contribution from the relative. If the relative pays a sum to the tenant each month, even presented as a "contribution to expenses," the landlord may see it as disguised subletting. Case law looks at economic reality: a regular payment proportional to occupancy strongly resembles rent.
2. Departure of the tenant. If the tenant leaves the dwelling leaving the relative in place, it is no longer accommodation: it is an assignment of the lease or total subletting, both subject to the landlord's consent. The relative becomes an occupant without right or title, exposed to eviction.
3. Lease clause. Some leases contain a clause prohibiting any occupation by a third party, even free of charge. Such a clause is in principle abusive because it disproportionately infringes on the tenant's privacy. But it can serve as leverage for a litigious landlord.
Concrete Example
Camille rents a three-room apartment in Lyon. Her partner moves in with her, without being mentioned on the lease. They share expenses: he pays her €400 per month "for rent and utilities." The landlord learns of this through the neighbors and sues Camille for lease termination due to unauthorized subletting.
The court will have to decide: are the €400 monthly payments a contribution to the couple's expenses or rent paid by a subtenant? If Camille proves that this amount corresponds to half of the actual expenses and that no enrichment results, free accommodation may be upheld. But the risk is real: a fixed, regular payment proportional to the rental value of the property objectively looks like rent.
Conversely, if the partner pays nothing and the couple lives together, the landlord has no legal leverage. Free accommodation of a cohabiting partner is a tenant's right, protected by respect for private and family life.
Exceptions to Know
Social housing. In the HLM sector, rules are stricter. The tenant must declare persons habitually living in the household, as the calculation of the solidarity rent supplement (SLS) and continued occupancy depend on it. Undeclared accommodation can lead to loss of the social housing.
Mobility lease. This short-term lease (1 to 10 months) is reserved for a tenant whose situation justifies temporary occupancy. Housing a third party for the entire duration of the lease may be considered a misuse of the contract's purpose.
Service accommodation. If the lease is tied to an employment contract, housing a third party may violate the conditions under which the dwelling was allocated.
Shared accommodation. In a shared lease with a single contract, each co-tenant may house a relative, but this can create tensions with other occupants. The landlord cannot oppose it, except under a specific and justified clause.
Checklist: Housing a Relative Without Risk
- Check that the lease does not contain a clause prohibiting accommodation (likely abusive, but anticipate it)
- Never accept regular payments from the housed relative
- If the relative contributes to expenses, do so occasionally and with documentation (invoices, receipts)
- Do not leave the dwelling leaving the relative alone for an extended period
- Inform the landlord in writing if the accommodation becomes long-term (more than 6 months), for transparency
- In social housing, declare the accommodation to the HLM organization
- Keep evidence of gratuity: absence of regular transfers, absence of a written lease with the relative
Possible Actions in Case of Dispute
For the tenant threatened with termination:
- Respond to the landlord in writing, recalling the principle: free accommodation is not subject to their consent
- Prove gratuity: affidavit from the relative, bank statements showing no regular payments
- Challenge the abusive clause if the lease prohibits all accommodation
- Refer the matter to the protection litigation judge if the landlord maintains the threat
For the landlord suspecting disguised subletting:
- Gather evidence: testimonies, bailiff's report, abnormal utility records
- Put the tenant on formal notice to justify the situation
- Sue for lease termination based on Article 8 of the 1989 law
- Caution: the burden of proving subletting lies with the landlord

FAQ
Does the tenant have to declare their cohabiting partner to the landlord? No. Cohabitation is a factual situation that requires no declaration. The landlord cannot oppose the move-in of a cohabiting partner, nor require their addition to the lease.
Can a parent house their adult child without the landlord's consent? Yes. Free accommodation of an adult child falls within the tenant's family life. The landlord cannot oppose it, unless the child pays rent to the parent.
Can the landlord increase the rent because one more person occupies the dwelling? No. The rent is set in the lease and does not depend on the number of occupants. No increase is possible for this reason.
What does a tenant risk for subletting without authorization? Termination of the lease at the tenant's fault, eviction, and restitution of rents received from the subletting. The landlord may also seek damages.
Can free accommodation become subletting over time? Yes, if financial consideration appears or if the tenant leaves the premises leaving the relative to occupy the dwelling. The legal classification depends on the facts, not intentions.
