La. Civ. Code art. 466
Current with changes from the 2024 Legislative Session
Things that are attached to a building and that, according to prevailing usages, serve to complete a building of the same general type, without regard to its specific use, are its component parts. Component parts of this kind may include doors, shutters, gutters, and cabinetry, as well as plumbing, heating, cooling, electrical, and similar systems.
Things that are attached to a construction other than a building and that serve its principal use are its component parts.
Other things are component parts of a building or other construction if they are attached to such a degree that they cannot be removed without substantial damage to themselves or to the building or other construction.
