Yes, the drone laws in France are pretty restrictive. Since 1st January 2016 you're not allowed to fly higher than 150 meters, or within 50 meters of a building, or with a machine weighing more than 2 kg. So there will be regulatory hurdles for sure.

Current laws, in French, are documented here: http://www.developpement-durable.gouv.fr/IMG/pdf/jo_pdf_frame-condition.pdf
