The posting of planning permission is a crucial stage in any construction or renovation project.
Not only is it compulsory, but it also serves to inform the public and guarantee the transparency of operations.
Why is it compulsory to display a building permit?
Article R. 424-15 of the Code de l'urbanisme requires that all building and development permits be posted. The main purpose of such posting is to enable third parties (neighbors, associations, local authorities) to become aware of the project and, if necessary, to contest the authorization granted within the statutory two-month period.
Failure to comply with this obligation may result in sanctions, including an extension of the contestation period or, in some cases, cancellation of the permit. It is therefore essential that this stage be completed before work begins.
Why is displaying planning permission essential?
Posting a building or development permit serves several purposes:
-
Public information: Neighbors and other interested parties are informed of the project and its nature.
-
Time limit for appeal: Posting the permit triggers the time limit for appeal by third parties, who can contest the permit if they feel it is prejudicial to their interests.
-
Legal compliance: Compliant signage is a legal obligation, failure to comply with which may result in sanctions.
How to display your town planning signs?
Signage must be visible and legible from the public highway.
Here are the rules to follow:
-
Location: The sign must be installed on the site concerned, in a position that ensures optimum visibility for anyone passing nearby.
-
Height and orientation: It must be positioned at least 1.50 m above the ground to ensure adequate legibility.
-
Legibility: Information must be clear, well contrasted and visible from a distance. The use of a rigid, weather-resistant sign is strongly recommended to avoid any deterioration.
Current regulations
The regulations governing the posting of planning permission are precise and must be scrupulously respected. Here are the key points:
-

Tips for a successful display
-
Choose a quality substrate: Choose a weather-resistant panel (PVC, correx) to guarantee the durability of your display.
-
Take care of legibility: Use a clear font and a font size that's easy to read.
-
Check the information: Make sure that all the compulsory information is present and correct. An error may result in your permit being contested.
-
Take photos: Keep dated and geotagged photos of the posted sign as proof of posting in the event of a dispute.
Affichage as a communication tool
Posting planning permission is more than just a legal obligation.
Done properly, it becomes a powerful communication lever, reinforcing transparency and confidence around your projects.
-
Enhancing your professionalism
Clear, compliant signage reflects your seriousness and expertise as a building or planning professional. It shows that you respect regulations and take care of administrative details. -
Preventing conflicts with neighbors
Informing your neighbors about upcoming construction work helps to anticipate their concerns. Proactive communication reduces the risk of misunderstanding or opposition, thus promoting harmonious coexistence. -
Facilitating the construction process
By displaying essential information on the permit, you ensure that the project is better understood by all stakeholders, including local authorities, local residents and the companies involved.
As a prime contractor or project owner, your attention to these details reinforces your image with stakeholders. Displaying them becomes tangible proof of your commitment to quality and transparency.
