Installing a flagpole in France: planning rules and foundation
Published Written by Flagpole Guides
This page is an English translation of the French original. Where the two versions differ, the French text is the original.
Installing a flagpole in France falls under the Planning Code (Code de l’urbanisme), the municipality’s local land-use plan (PLU) and, before digging, the rules on works near networks. For most garden and business poles no formality is required, but height and location change things. This guide presents the rules and the usual stages of an installation.
Exemption, declaration or permit
The Planning Code classifies new structures by height, footprint and floor area. A free-standing pole has a very small footprint and floor area, so it is mainly its height and location that count:
| Situation | Formality under the Planning Code |
|---|---|
| Pole of 12 m or less, outside protected areas | Exempt from any formality (article R. 421-2) |
| Pole over 12 m, outside protected areas | Prior declaration (article R. 421-9, c) |
| Pole of 12 m or less, in a protected area | Prior declaration (article R. 421-11) |
Under article R. 421-2, the exemption covers structures that meet three cumulative criteria: a height above ground of 12 metres or less, a footprint of no more than 5 m² and a floor area of no more than 5 m². The protected areas are the perimeter of a remarkable heritage site (site patrimonial remarquable), the surroundings of historic monuments and listed sites or sites being listed; article R. 421-11 adds, among others, nature reserves and the core of national parks.
A bracket fixed to a façade is not a new structure but work on an existing building. Under article R. 421-17, works that change the external appearance of an existing building require a prior declaration, except ordinary maintenance or repair work. The town hall can say whether a given bracket falls into this case.
The prior declaration
According to Service Public, the prior declaration (déclaration préalable) is filed at the town hall, and the processing time is in principle one month from the filing of a complete file; it is longer in protected areas, where the architecte des Bâtiments de France is consulted. If there is no answer within that time, the project generally benefits from a decision of non-opposition, and the authorisation is displayed on the land.
Local plan, co-ownership and neighbours
Under article L. 421-8 of the Planning Code, a structure exempt from formalities must still comply with planning rules. The PLU can set rules on height, distance from boundaries or external appearance. In a co-ownership (copropriété), installing a pole or a bracket on the common parts or the façade falls under the co-ownership rules and, most often, a decision of the general meeting. A housing estate may have its own rules or specifications. A pole close to the edge of the plot can also bother a neighbour; the Civil Code deals with nuisance between neighbours.
Buried networks
Before a foundation is dug, the Environmental Code organises the prevention of damage to networks. Under article R. 554-20, whoever is responsible for the project first checks, by consulting the single portal “Réseaux et canalisations”, whether there are networks in or near the works area. Where applicable, they then send a declaration of planned works (DT) to the operators, and the contractor a declaration of intent to start works (DICT). According to Service Public, a private individual can be the declarant, and certain works without building permission and with no impact on underground networks, away from overhead lines, are not subject to a DT-DICT.
Overhead power lines matter too: a pole is generally sited so that it cannot touch a line, even if it falls.
The foundation
Most fixed poles stand on a concrete block, in which a ground sleeve or anchor rods for a base plate are set. The size of the block depends on the pole height, the flag size, the ground and the wind. Makers state the foundation dimensions for their poles, with reference to the wind regions of the national annex to Eurocode 1 (NF EN 1991-1-4). A roof or façade pole is fixed to a support whose strength a professional can check.
In practice
In practice, an installation often involves enquiring at the town hall about the PLU and any protected area, a prior declaration where the height or location calls for one, consulting the single networks portal, a foundation built to the maker’s specifications, and then setting up the pole, with several people or lifting equipment for a large pole.
More on this is in the guides to flagpole safety and flagpole transport.
Frequently asked questions
Is planning permission needed for a flagpole?
Under article R. 421-2 of the Planning Code, a new structure up to 12 metres high, with a footprint and floor area of no more than 5 m², is exempt from any formality, except within a remarkable heritage site, near historic monuments or in a listed site. Above 12 metres, article R. 421-9 provides for a prior declaration.
And in a protected area?
Under article R. 421-11, within a remarkable heritage site, near historic monuments, in a listed site or one being listed, in a nature reserve or in the core of a national park, a new structure of 12 metres or less requires a prior declaration.
Is a pole exempt from formalities free of all rules?
No. Under article L. 421-8 of the Planning Code, structures exempt from formalities must comply with planning rules, for example those of the local land-use plan on height, siting or appearance. Co-ownership rules or the specifications of a housing estate may also apply.
Do works near buried networks have to be declared?
Under the Environmental Code (article R. 554-20), whoever is responsible for a works project first checks with the single networks portal whether there are networks within the works area. According to Service Public, a private individual can be the declarant; certain works without building permission and with no impact on underground networks are not subject to a DT-DICT.
Who can answer for a specific case?
The town hall’s planning department, which can state the zoning of the local plan, any protected area and the formality that applies. In a protected area, the architecte des Bâtiments de France (the State’s heritage architect) is consulted on the project.
