Urban planning law

Droit de l’urbanisme

A vast and complex field


Urban planning law is subject to numerous legal and technical rules. This framework requires precise knowledge of its content, as well as permanent updating.

CARNOT AVOCATS intervenes on all the issues of town planning law: the different uses of the land, the rules of constructability and development, as well as the mechanisms of land actions.

Town planning law induces the application of many specific standards and documents, in addition to the Town Planning Code: Territorial coherence schemes (SCOT), Local Town Planning Plans (PLU), communal maps, Mountain law, Coastline, remarkable heritage sites, …

It also concerns works, development and construction projects. As such, different planning permissions exist depending on the projects (prior declaration, building permit, development permit, demolition permit).

It also creates various land action mechanisms. We find here the subjects of land reserves, ZAC, preemptions, or even expropriation.
The field of urban planning can also present specificities specific to certain sectors, such as commercial urban planning for example.

Urban planning law is therefore a complex, technical and evolving law.

CARNOT AVOCATS is committed to providing you with technical and human support thanks to its recognized expertise in this area.
