📍 My experience: During my last extension last March, I almost saw my project fail due to non-compliant on-site posting. I had to prove the visibility of my sign from the public road with dated photos to validate the appeal period. The lesson learned is that proof of posting is worth as much, if not more, than the town hall order itself.
Understanding the role of opinions and our service catalog
✅ Advantages
- 24/7 online submission
- Immediate acknowledgment of receipt
- Real-time tracking of the review process
🔍 Drawbacks
- Complexity of file formats
- Risk of bugs on certain portals
After submitting your file, the administration begins a review phase where several opinions determine the fate of your project.
Distinction between favorable, unfavorable, and tacit opinions

The favorable opinion authorizes your work, while the unfavorable one blocks it. In this process, the mayor’s signature remains the central pivot validating the final decree.
The tacit opinion is triggered if the town hall remains silent past the review deadline. For the applicant, this administrative silence then amounts to legal acceptance.
To prepare your site before the work, I recommend consulting our file on the as-built plan which is essential. If your project concerns a specific area, the article on house extension will be very useful to you. Finally, to anticipate the next steps, the guide on site monitoring provides valuable advice.
Some technical reports, issued by the instructing services, carry significant weight. They often dictate the final position of the local elected official on the viability of the submitted file.
The tacit approval constitutes a major legal safeguard to avoid administrative inertia during the instruction process.

Once the opinion is issued, you have the legal right to consult all the documents that make up your administrative file at the town hall.
Procedure to consult your file at the town hall or online
The right of communication via the CADA guarantees transparency. Any citizen can request copies of the documents. This procedure takes place as soon as the decision is made.
Digital portals now dematerialize the instruction process. You can follow the progress of the file without traveling. These tools greatly facilitate your procedures.
The mandatory posting informs third parties on site. However, only consultation at the town hall reveals the complete technical file.
🌍 Did you know?
In 2026, the absence of posting the building permit sign on your site can result in a fine of up to 1500 euros and allows neighbors to contest your construction for 1 year after the completion of the work.
Administrative transparency is a fundamental right guaranteed by the code of relations between the public and the administration.

Managing complex opinions from the ABF and associated fees
Certain protected areas require the involvement of external experts, which can influence both the design and the cost.
The impact of the Architect of the Buildings of France on your project
The ABF’s approval is often essential for obtaining your authorization. Its prescriptions are binding. In protected zones, its veto systematically blocks your construction file.
These specific opinions are added to the public file at the town hall. However, they may include partial redactions. This protects the privacy of third parties. Industrial secrets are also preserved.
These constraints preserve the local heritage. However, they require very particular technical expertise to succeed.
