Where only part of a building belonging to the State or the département is made available, the establishments referred to in article L. 3221-4 may only carry out enlargement or demolition work with the agreement of the local authority that owns the building.
In this situation, the distribution of the operating costs of the building as well as the rights and obligations arising from the contracts mentioned in the third paragraph of article R. 3221-12 are the subject of an agreement between the establishment and the owner local authority. This agreement sets out in particular the institution’s contribution to the financial costs arising from these contracts.
