The DALO appeal is based on a specific legal mechanism: the State, designated as the guarantor of the right to housing by the law of March 5, 2007, can be compelled by the administrative judge to rehouse a household recognized as a priority. This obligation to achieve results distinguishes DALO from all other access to social housing schemes, which operate under a discretionary allocation logic.
Abnormally long delay: the most misunderstood criterion of the DALO appeal
The notion of abnormally long delay is the most frequent reason for referring to the mediation commission, and also the most confusing. This delay is not set nationally: it varies from one department to another, depending on local rental pressure.
A national notice attached to the appeal forms now lists, department by department, the duration after which a social housing applicant can consider their wait as abnormal. In Île-de-France, this threshold is significantly higher than in the provinces, reflecting the pressure on the social housing stock in the Paris region.
We recommend checking this delay before any referral. An appeal submitted too early will be rejected by the mediation commission, with no possibility of immediate legal recourse. Conversely, an applicant who significantly exceeds the delay set for their department has a objectively stronger case, provided that their social housing application has been regularly renewed.
Understanding the DALO system for housing requires distinguishing this temporal criterion from the six other grounds for referral (absence of domicile, threat of eviction, accommodation in a structure for more than six months, housing unfit for habitation, overcrowding, presence of a minor child or a disabled person in indecent housing).
DALO mediation commission: role, composition, and limits of the decision
The mediation commission (COMED), established in each department, is the central body of the system. It does not house anyone. The COMED recognizes the priority and urgency of a request, and then refers the household to the prefect for rehousing.
Its composition includes representatives from the State, local authorities, social landlords, approved associations, and collecting organizations. This plurality aims to provide diverse perspectives on each situation, but it also leads to differing assessments from one department to another on comparable cases.
What the COMED examines concretely
The case is evaluated on three axes: the administrative regularity of the applicant (valid residence permit, income conditions in line with social housing ceilings), the reality of the claimed housing situation, and the prior steps taken. On this last point, the commission verifies that the applicant has completed at least one active step (social housing application submitted, report to the hygiene service, formal notice to the landlord).
The income ceilings were updated by an order dated December 19, 2025, applicable from January 1, 2026. They are based on the 2024 reference tax income and vary according to geographical areas and the PLUS or PLAI categories. In Île-de-France, the thresholds remain higher than in the provinces.
Favorable decision: and then?
Once the household is recognized as a priority, the prefect has a deadline to propose suitable housing. If no proposal is made within this timeframe, the applicant can take the matter to the administrative court. The judge can then order the State to rehouse the applicant, accompanied by a financial penalty.
We observe that this penalty, paid into the national fund for support towards and in housing, does not directly benefit the applicant. The penalty punishes the State but does not mechanically accelerate rehousing, due to the lack of available housing in high-pressure areas.
Online submission of the DALO appeal: what changes in 2025-2026
Until recently, the DALO appeal was exclusively submitted by postal mail of the CERFA form to the departmental mediation commission. Since 2025, several departments have opened an online submission tele-service.
The DRIHL Île-de-France has set up a dematerialized platform covering the eight departments of the Paris region. Pilot sites are also operating in other departments such as Gironde or Loire-Atlantique. This dematerialization concretely modifies the procedure:
- The receipt of submission is generated automatically, securing proof of referral and the start date of the processing period by the COMED
- The supporting documents are uploaded directly, reducing postal back-and-forth for incomplete files
- The status of the appeal can be tracked online in equipped departments
The paper form is still accepted everywhere. Dematerialization is not yet widespread across the entire territory, and some households in significant digital precarity continue to receive support from approved associations for submission.
Contentious DALO appeal before the administrative court: conditions and real scope
The contentious appeal is only open to applicants already recognized as priority by the COMED who have not received any suitable housing proposal within the allotted time. Without a favorable decision from the COMED, the administrative court is incompetent.
The judge verifies the State’s failure, not the relevance of the commission’s decision. They cannot designate a specific housing unit either: they order the prefect to propose rehousing that meets the household’s needs.
- The order may set a deadline for execution (usually a few months) and a daily penalty in case of non-compliance
- The applicant may be assisted by a lawyer or an approved association, with legal aid available subject to income conditions
- In Île-de-France, the volume of contentious DALO appeals significantly burdens the administrative courts, extending hearing times
The contentious appeal remains a real legal pressure lever, but it faces a structural problem: the shortage of social housing in the most pressured areas makes the execution of court decisions difficult, even when the State is condemned.
The DALO does not create housing. It redistributes the order of priority within an existing stock. Any appeal strategy must integrate this reality to accurately assess the actual rehousing delays after recognition.
