The task of the French Housing Solidarity Fund commissions, established by the Besson Law of 31 May 1990, is to provide monetary assistance and social support schemes for households with dwelling-related difficulties (different costs of access to housing, rental arrears, etc.). Combining the approaches of urban sociology, the sociology of social policies and that of local power, this article offers a comparative analysis of the deliberation and allocation practices of three municipal commissions in one departement in the greater Paris region in order to shed light on the locally differentiated forms and unequal treatment of households that structure the implementation of this historic access scheme for the right to housing.
