A neighbor consistently parks their vehicle in front of your entrance, and you are considering placing a large flower pot on the sidewalk to block access. The temptation is common, but it poses a direct legal problem: the sidewalk does not belong to you, even if it runs alongside your facade.
Article R.116-2 of the Roadway Code: the basis that few residents know
It is often thought that placing a flower pot on a sidewalk is a minor infraction without consequences. However, Article R.116-2 of the Roadway Code states otherwise: occupying public roadway space without authorization is a 5th class offense. This level of sanction far exceeds mere obstructive parking.
Specifically, this article targets the act of occupying all or part of the public roadway or depositing items there without authorization. A flower pot, a plastic bollard, an overturned trash can, a concrete block: all these objects fall under the same regulation.
One can explore the question of whether it is permissible to place flower pots on the sidewalk with Ma Maison Idéale, which details the various situations encountered by residents. The key distinction to remember: it is not the nature of the object that matters, but the fact that it has been placed in a public space without an occupancy title.
Temporary Occupation Authorization for the Sidewalk: the only legal procedure

If one wants to install anything on the sidewalk (planter, container, furniture), they must obtain a Temporary Occupation Authorization (AOT) issued by the town hall. There are no exceptions for residents, regardless of the planned duration of installation.
Municipalities like Cayenne now systematically remind that any occupation of public space, whether it involves a construction site, a dumpster, or a planter, requires a municipal order. This trend of formal reminders is observed in several French cities.
The AOT request is made at the town hall. A file is submitted that specifies the nature of the installation, its duration, its exact location, and its dimensions. The town hall checks that the pedestrian passage remains clear and that the installation does not create any danger.
- The form is generally available at the town hall’s public works or urban planning department, sometimes online.
- The authorization may be refused if the sidewalk is too narrow or if the object obstructs the visibility of motorists.
- The AOT is always temporary and revocable: the municipality can demand removal at any time for work or redevelopment.
Without this authorization, even a flower container placed “for aesthetics” remains an illegal occupation. The aesthetic reason or voluntary maintenance of the sidewalk does not change its legal status.
Greening Permit: a legal but different alternative
Some cities offer a greening permit that allows residents to plant at the base of walls or in designated spaces on the sidewalk. This provision is often confused with a right to place any container anywhere.
The greening permit precisely regulates what is planted, where, and how. It requires leaving a sufficient passage width for pedestrians, strollers, and wheelchairs. Plants must not obstruct visibility or encroach on the roadway.

This permit does not cover the installation of large containers intended to block parking. Greening a sidewalk and reserving a parking space are two processes that the town hall treats very differently. If your real goal is to prevent a vehicle from parking, the greening permit will not protect you in case of inspection.
Concrete risks and official removal of flower pots from sidewalks
In practice, when the town hall detects unauthorized occupation, it first sends a letter requesting the removal of the object within a specified timeframe. If nothing changes, municipal services proceed with the official removal at the offender’s expense.
The 5th class fine can reach a significant amount, far beyond a simple parking ticket. In densely populated urban areas, responses vary on this point according to municipalities: some issue fines quickly, while others tolerate for months before taking action. This local tolerance does not create any acquired rights.
Another often overlooked risk: civil liability. If a pedestrian trips over your planter placed without authorization, you are responsible for the damages. An unmarked, low, dark flower pot constitutes a dangerous obstacle, especially at night.
- The town hall can remove the object without notice in case of immediate danger to pedestrians.
- Your home insurance may not cover damages caused by an object illegally placed on public property.
- In a co-ownership, the property manager may also intervene if the installation affects common areas or the image of the building.
Obstructive parking in front of your home: what to do without breaking the law
Rather than placing a flower pot at the risk of a fine, one can report the abusive parking to the municipal police. A vehicle parked in a troublesome or prolonged manner in front of a driveable entrance can be subject to a ticket, or even towed.
Another option: request the town hall to install a curb cut with ground marking in front of your garage entrance. This official device prohibits parking and provides a legal basis for ticketing offenders.
The public road remains a shared space, managed by the municipality. Even after years of voluntary maintenance of the sidewalk in front of their house, no resident acquires exclusive rights to this space. Any installation must go through the town hall, and a refusal is always possible.
