It depends. Indeed, on the death of the tenant, the rental contract can be transferred to the descendants who lived with him for at least one year on the date of death (art. 14 law n ° 89-462 of July 6, 1989), including when this accommodation belongs to a low-cost housing organization (art. 40 law n°89-462 of July 6, 1989).

If this condition is not met, the lessor can offer relocation to a smaller accommodation for which the person concerned has priority.
