If 115 or the SIAO do not offer me any accommodation solution, I can make a DAHO appeal (Enforceable Right to Accommodation) which theoretically obliges the State to find me an accommodation solution within three weeks.
For this, I fill the DAHO appeal form , explaining my situation and I refer it to the Mediation Commission of my department.
I can get help with my DAHO appeal from a social worker or from an association specializing in the right to housing.
