Social housing, housing aid & DALO 2 min read · published September 11, 2025
As a tenant in France, understanding the differences between APL, ALS and ALF can make it easier to access housing aid and avoid mistakes during procedures. These benefits, managed by the Caisse d'Allocations Familiales (CAF), respond to distinct criteria: resources, type of housing and family situation. Knowing which aid applies affects the amount calculation, the submission of the application and the supporting documents to provide. This guide simply explains who can claim each aid, how to estimate potential aid, which documents to prepare and where to apply. It aims to give clear steps for tenants to act quickly and confidently.

Understanding APL, ALS and ALF

APL (Personal Housing Assistance), ALS (Social Housing Allowance) and ALF (Family Housing Allowance) are distinct benefits aimed at reducing a tenant's out-of-pocket costs. The type of aid depends on the housing, household resources and family situation: for example, APL often applies to conventioned housing while ALS and ALF target other specific situations[1]. The legal bases frame these aids and specify calculation rules and the obligations of the parties.[2]

Aid depends on family situation and the type of housing.

Who can benefit?

  • Amounts (amounts) and household income ceilings, depending on household composition.
  • Type of housing: conventioned housing, social housing or private non-conventioned housing.
  • Personal situation: student, single parent, employee, retiree or other.
  • Payment of the rent (rent) and existence of an ongoing lease are required for most applications.
Keep your income proofs and your rental contract.

How are aids calculated?

The calculation combines household resources, the rent amount and parameters specific to each benefit (APL, ALS, ALF). Precise rules are set out in the Code and interpreted by the CAF and regulatory texts; the exact amount may vary depending on departments and the nature of the housing.

The CAF publishes simulators to estimate entitlements before submitting an application.
