Short answer. Under Article 415 of the Civil Code, machinery installed by the owner of a tenement for the industry or works conducted on that property is classified as immovable (real) property, as long as the machinery is intended to meet the needs of that industry or works.
What the law says
Machinery, receptacles, instruments or implements intended by the owner of the tenement for an industry or works which may be carried on in a building or on a piece of land, and which tend directly to meet the needs of the said industry or works

The rule under Article 415
Article 415 of the Civil Code lists what counts as immovable property. Item 5 on that list covers machinery, receptacles, instruments or implements intended by the owner of the tenement for an industry or works carried on in a building or on land, and which tend directly to meet the needs of that industry or works. When a factory owner installs heavy machinery to operate the factory on that land, the machinery falls squarely within this definition and is classified as real property — not personal property — for legal purposes.
Two conditions that must both be met
The classification is not automatic for any machine found on land. Two conditions must be satisfied. First, the machinery must be intended by the owner of the tenement for the industry or works — this is a question of intention and purpose, not merely physical location. Second, the machinery must tend directly to meet the needs of that industry or works. A machine sitting in storage with no operational connection to the business, or machinery owned by a tenant rather than the land owner, may not qualify. The relationship between the machine and the specific enterprise on the land is what determines the classification.
Why the classification matters
Whether something is real or personal property has practical consequences across several areas of law. Real property taxes assessed by the local government apply to immovable property — machinery classified as real property can be taxed by the city or municipality as part of the assessed value of the property. In mortgage and financing arrangements, real property requires different documentation and registration than personal property. In insolvency and execution proceedings, rules on how creditors can reach real versus personal assets differ. Understanding the classification in advance helps owners structure their transactions and obligations correctly.
The owner requirement is critical
The article specifically refers to machinery intended by the owner of the tenement. This means the rule applies when the machinery is installed by the person who owns the land or building, for the industry conducted there. If machinery is installed by a lessee or a third party rather than the land owner, the analysis changes — the machinery may remain personal property of the lessee despite being physically attached to the premises. This distinction becomes important when a lease ends, when a property is sold, or when a creditor tries to reach assets.
