Receiving a rejection letter after months, sometimes years of waiting for social housing, creates a feeling of deadlock. The allocation commission has made its decision, and your application has not been selected. However, this refusal is not the end of the road. Several avenues exist to contest this decision or assert your rights in other ways.
Understanding the Reason for Refusal Before Taking Action
Before launching an appeal, the first step is to obtain the exact reason for the refusal. The housing allocation commission (CAL) is required to justify its non-allocation decisions. This requirement is governed by the Construction and Housing Code.

You can send a letter to the social landlord requesting a written and detailed notification. Without this document, it will be difficult to build a solid argument later on.
The most common reasons concern the mismatch between the size of the housing and the composition of the household, resources deemed insufficient or too high, or an incomplete application. Identifying the precise reason guides the next steps in your process.

Some refusals are based on contestable criteria. An applicant recognized as a priority by the DALO mediation commission may, for example, have their application rejected by the CAL of a landlord. The Council of State has ruled that this type of decision can be contested before an administrative judge. It is useful to know the appeals after a social housing refusal to assess your options at this stage.

DALO Appeal: Conditions and Deadlines Depending on Your Area
The DALO appeal (right to housing) is not intended to contest a specific refusal. It aims to recognize a priority for rehousing in a broader application. The distinction is significant: you are not requesting the annulment of a CAL decision, but the recognition of your urgent situation by the departmental mediation commission.
To file a DALO appeal, you must demonstrate that your application for social housing has gone unanswered for an “abnormally long” period. These deadlines vary greatly depending on the area.
Very Different Thresholds from One Department to Another
Prefectural orders set these thresholds. In very tense areas like Paris, the period recognized as abnormally long can reach several years, far beyond what is observed in less tense areas where it may only be a few years. The difference is considerable and determines the admissibility of your application.
- Gather the complete history of your application: unique number, date of initial submission, renewals, proposals received, and refusals encountered
- Compile a chronological table of your applications, including those made on the AL’in platform of Action Logement, with screenshots of offers and responses
- Attach any document proving your urgent situation: eviction notice, accommodation certificate from a third party, medical certificate if the current housing is unsuitable
Proof of AL’in applications is now accepted as evidence in DALO cases. Documenting each interaction with Action Logement strengthens your case before the mediation commission.
Contacting the DALO Mediation Commission: Procedure
The request is made via a Cerfa form, sent by registered mail to the prefecture of your department. The commission has three to six months to make its decision, depending on whether the request concerns housing or accommodation.
If the commission recognizes you as a priority, the prefect is obliged to offer you suitable housing. In the absence of a proposal within the allotted time, a second appeal can be made to the administrative court.
Contentious Appeal Before the Administrative Court
This appeal is specific to individuals recognized as DALO priorities. The administrative judge can order the prefect to proceed with your rehousing under penalty. The amount of this penalty is paid to the National Fund for Support Towards and In Housing, not to the applicant.
A social worker or a lawyer specializing in housing law can assist you in this process. Legal aid is available subject to income conditions to cover costs.

Social Housing Refusal and Discrimination: An Often Overlooked Angle
Do you feel that the refusal is based on a discriminatory criterion? Origin, family situation, disability, source of income: the law prohibits any discrimination in access to social housing.
The Defender of Rights can be contacted free of charge if you suspect discrimination. The process can be done online or by mail. The Defender of Rights has investigative powers and can issue binding recommendations to the landlord.
- Keep all correspondence with the landlord or the allocation commission
- Note oral exchanges (date, interlocutor, content of the exchange)
- Systematically request a written response to each proposal or refusal
- Contact an ADIL (Departmental Agency for Housing Information) for free and personalized legal advice
ADILs offer free support to analyze your case and identify the most suitable appeal for your situation. They are familiar with local landlord practices and actual processing times.
A refusal of social housing does not close the door permanently. The key lies in the rigorous documentation of each step of your journey. A well-constructed file, with dated evidence and a complete history, carries weight before a mediation commission or an administrative court. The delays remain long, but every document submitted to the file brings you closer to a favorable outcome.
