A favorable opinion from the allocation commission does not guarantee the handover of keys. When Caleol reviews a housing application, it can rank several files in order of priority. A candidate ranked 2 or 3 has a favorable opinion but will only be offered the housing if the higher-ranked candidates withdraw or do not complete their file. Understanding this ranking mechanism is the starting point for any effective response.
Ranking in the allocation commission: what the notification does not say
Caleol allocates housing by designating a selected candidate and, in most cases, one or more candidates ranked as substitutes. The notification received by the applicant rarely mentions this rank explicitly.

We recommend requesting in writing the exact rank of the file as soon as the favorable opinion is received. The request should be addressed to the social landlord or the reserving authority (town hall, prefecture, Action Logement) depending on the quota to which the housing belongs. A registered letter with acknowledgment of receipt remains the most solid form, but an email with a read receipt is sufficient to trigger the obligation to respond.
If the landlord refuses to disclose the rank, the Commission for Access to Administrative Documents (CADA) can be contacted. The decision of Caleol constitutes an administrative document that must be communicated to the concerned applicant. Knowing one’s rank allows for an assessment of real chances and guides the next steps: active waiting if the rank is second, parallel search and appeal if the rank is further away.

Many applicants share this situation on specialized forums. Several concrete feedbacks can be found in the thread dedicated to the favorable opinion commission allocation housing forum on Ciblimmo, where exchanges between tenants detail the observed timelines after being ranked as substitutes.

Appeal after housing allocation to another candidate
A favorable opinion followed by an allocation in favor of another household does not close the file. Several levers exist, but their effectiveness depends on timing and the quality of the retained documents.
Gracious appeal to the landlord
The first lever is the gracious appeal addressed to the general director of the HLM organization. This letter requests a re-examination of the file and a precise justification for the decision to allocate the housing to another candidate. The landlord must justify any implicit refusal of allocation when the applicant has received a favorable opinion from the commission.
The gracious appeal does not have a strict legal deadline, but we observe that beyond two months without a response, silence amounts to an implicit rejection. This rejection opens the way for contentious appeal.
Referral to the DALO mediation commission
If the applicant meets the conditions for the right to housing, the DALO mediation commission constitutes the most structured appeal. Referral is possible when the applicant has not received an appropriate offer within an abnormally long time, considering their situation and geographic area.
The mediation commission examines the overall situation of the household, not just the housing in question. If it recognizes the priority and urgency of the request, it issues a favorable decision that obliges the prefect to propose housing within a specified timeframe.
- Keep the notification of favorable opinion, the unique application number, and any correspondence with the landlord or reserving authority
- Attach to the DALO file proof of the age of the application and supporting documents of the situation (housing, overcrowding, unsanitary conditions)
- Send the Cerfa referral form by registered mail to the secretariat of the departmental mediation commission
Contentious appeal before the administrative court
If the mediation commission recognizes the household as a priority but no offer is made within the allotted time, the applicant can refer the matter to the administrative court. The judge can issue a relocation injunction with a penalty against the State. This appeal assumes that the DALO procedure has been completed.
Supplementary documents and allocation reserve: avoid the trap of an incomplete file
The favorable opinion is sometimes accompanied by a reserve, most often the production of a supplementary document (employer’s certificate, updated tax notice, recent proof of residence). The commission sets a deadline, rarely explicit in the notification.
Sending the missing document within 48 hours with proof of receipt is the only way to secure one’s position. A late or incomplete submission is enough to shift the allocation to the candidate ranked next, without the landlord needing to justify their decision otherwise.
We recommend doubling the submission: an email with the attachment to the file manager, and a registered letter to the landlord’s headquarters. In case of a later dispute, proof of timely submission becomes the key document in the file.

Quota and reserving authority: identify the right contact
Social housing always falls under a quota: prefectural, municipal, Action Logement, or specific to the landlord. The reserving authority is the one who proposed the application to the commission. In case of competition, this is who should be contacted first.
- Prefectural quota: contact the departmental directorate of employment, labor, and solidarity (DDETS)
- Muncipal quota: contact the housing service of the town hall
- Action Logement quota: contact the housing advisor linked to the employer
- Landlord’s specific quota: write directly to the rental management department
Identifying the quota allows understanding who presented the competing files. The reserving authority can sometimes reposition a candidate to another housing unit in the same portfolio without going through a new commission, which significantly shortens the waiting time.
The situation of competition after a favorable opinion remains common in tight areas where demand far exceeds supply. Obtaining one’s rank, building a solid appeal file, and targeting the right contact are the three actions that transform a theoretical favorable opinion into effective allocation. Every exchange with the landlord or reserving authority must leave a written trace, without exception.
