The rent for accommodation offered by a Social Housing Agency is fixed in the rental lease and regulated by law at a level below the market price.
The rent is defined in relation to the rent fixed with the owner of the accommodation. The Social Housing Agency  guarantees the tenant a rent below the market price. The tenant therefore benefits from an additional reduction granted by the Social Housing Agency in relation to the rent fixed by the landlord on condition that he justifies each year that he meets the conditions of maximum household income.
