Yes, each joint tenant can benefit from accommodation assistance.
Indeed, co-renting is the equivalent of sharing accommodation between several people not living as a couple. The CAF therefore considers each joint tenant as a beneficiary, who has separate rights.
The names of all joint tenants must appear on the lease agreement, or each joint tenant must have signed a lease agreement in their name.
Finally, each joint tenant must make their own request for assistance, by declaring their personal income. Calculating accommodation assistance takes into account the share of rent paid by each person.
