French Urban Planning Law: PLU, Building Permits, and Expropriation

French urban planning law (droit de l’urbanisme) regulates land use, construction, and development across the French territory. The field is governed by the Code de l’urbanisme, which establishes a hierarchical system of planning documents, construction permitting, and land use controls. French urban planning law reflects the tension between private property rights and the public interest in orderly development, environmental protection, and social cohesion.

The Code de l’Urbanisme

The Code de l’urbanisme codifies French urban planning law. The Code is divided into several parts: general principles (Book I), planning documents (Book II), development permits (Book III), land policy and expropriation (Book IV), and enforcement (Book V). The Code establishes the legal framework for local planning authorities to regulate land use within their territories.

The Code has been significantly modified over time to incorporate environmental concerns, public participation requirements, and the principles of sustainable development. The Loi Solidarité et Renouvellement Urbains (SRU) of 2000 introduced major reforms to the planning system, including the creation of the Plan Local d’Urbanisme (PLU) and the Schéma de Cohérence Territoriale (SCOT). The Loi pour l’Accès au Logement et un Urbanisme Rénové (ALUR) of 2014 further reformed the system.

Plan Local d’Urbanisme (PLU)

The Plan Local d’Urbanisme (PLU) is the principal local planning document. It sets out the land use policies for a municipality or group of municipalities. The PLU divides the territory into zones: urban zones (U), zones for future urbanisation (AU), agricultural zones (A), and natural and forest zones (N). Each zone is subject to specific regulations governing the types of construction permitted, building density, height limits, and other requirements.

The PLU must comply with higher-level planning documents, particularly the Schéma de Cohérence Territoriale (SCOT) and the Schéma Directeur de la Région Île-de-France (SDRIF). The PLU is adopted by the municipal council after a public inquiry process that allows residents and stakeholders to comment on the proposed plan.

Schéma de Cohérence Territoriale (SCOT)

The Schéma de Cohérence Territoriale (SCOT) is a strategic planning document that coordinates land use policies across multiple municipalities. The SCOT establishes the broad framework for development, including housing, transportation, economic development, and environmental protection. The SCOT must be consistent with regional and national planning policies.

The SCOT operates at the level of a bassin de vie (living area), typically covering a group of municipalities that share economic and social ties. The SCOT is prepared by a public authority established by the participating municipalities and is adopted after a public inquiry. All PLUs within the SCOT area must be compatible with the SCOT.

Building Permits

Construction in France generally requires a building permit (permis de construire). The permit is issued by the mayor (or the préfet in certain cases) after verifying that the proposed construction complies with the PLU and other applicable regulations. The permit grants the right to construct, but it does not exempt the builder from complying with other legal requirements, including the Code civil (neighbour rights) and the Code de la construction et de l’habitation.

The permit application must include detailed plans and specifications demonstrating compliance with planning regulations. The authority has three months to examine the application. If the application is incomplete, the authority may request additional information. The permit may be refused if the proposed construction violates planning regulations or if it poses a risk to public safety, health, or environmental protection.

Other Development Permits

French planning law recognises several types of development permits in addition to the permis de construire. The permis d’aménager (development permit) is required for land subdivision (lotissement) and other development projects that involve substantial modifications to the land. The déclaration préalable (prior declaration) is a simplified procedure for minor works, such as building extensions or changes to the external appearance of a building.

The certificat d’urbanisme (planning certificate) provides information about the planning rules applicable to a specific property. The certificate may be informational (indicating the applicable rules) or operational (indicating that a proposed project is permissible). The operational certificate has legal effects: if the administration issues a certificate stating that a project is permissible, it cannot later refuse a permit for the same project.

Expropriation Pour Cause d’Utilité Publique

Expropriation for public purposes (expropriation pour cause d’utilité publique) allows the state and other public authorities to acquire private property for public projects. The procedure is governed by the Code de l’expropriation pour cause d’utilité publique and is subject to strict conditions: the expropriation must be justified by a public purpose, the property owner must receive fair compensation (juste et préalable indemnité), and the procedure must respect the rights of the owner.

The expropriation procedure has two phases: the administrative phase, in which the public authority declares the project to be of public utility (déclaration d’utilité publique, DUP), and the judicial phase, in which the court determines the compensation. The DUP is issued by the préfet after a public inquiry. The owner may challenge the DUP before the administrative courts on grounds of necessity or proportionality.

The compensation is determined by the juge de l’expropriation (expropriation judge). The judge assesses the value of the property based on its condition at the time of the DUP, considering its location, characteristics, and potential uses. The owner is entitled to compensation for the loss of the property, relocation costs, and any other damages caused by the expropriation.

Enforcement

Planning violations are enforced by the Code de l’urbanisme through administrative and criminal sanctions. The mayor or the préfet may issue an order to stop work (arrêté interruptif de travaux) when construction is being carried out without a permit or in violation of planning regulations. The order may be accompanied by an administrative fine.

Criminal sanctions apply to the most serious violations. Unauthorised construction is a criminal offence punishable by imprisonment and fines. The court may order the demolition of unauthorised constructions or the restoration of the site to its original condition. The limitation period for planning violations is six years.

Judicial Review

Planning decisions are subject to review by the administrative courts. The recours pour excès de pouvoir allows third parties to challenge the legality of planning permits and decisions. The standing requirement is broad: any person who has a sufficient interest, including neighbours and residents’ associations, may challenge a planning decision.

The review is based on the law at the time the decision was made. The court examines whether the decision was based on a correct interpretation of the planning regulations, whether the authority considered all relevant factors, and whether the decision is proportionate. If the decision is annulled, the construction must stop, and any works already carried out must be restored.
