In Louisiana your neighbor does not have to touch you to owe you. He only has to make your own yard unusable. 🏚️
Article 667 of the Louisiana Civil Code is one of the quietest and most powerful things in our law. The idea behind it is called vicinage, and it comes down to us through France from Rome. It says that although you may do with your own property as you please, you may not make any work on it that deprives your neighbor of the liberty of enjoying his own, or that causes damage to him.
Most of the country handles this through nuisance law, which generally asks whether you behaved unreasonably. Louisiana asks a different question. Our tradition starts from the premise that ownership itself comes with an obligation attached to the land rather than merely to the person standing on it. The duty runs with the dirt.
In practice it has covered exactly what you would hope. Smoke and fumes carried across a property line. Pile driving that cracked the walls of the house next door. Drainage rerouted so that one man's runoff now sits in another man's yard. Industrial operations that made the homes beside them unlivable. Louisiana courts have leaned on article 667 in some of the most significant environmental and industrial cases in this state's history, and for certain ultrahazardous activities it has been applied without requiring any proof that the neighbor was careless at all.
And it works at the smallest scale too. The barrel fire. The truck on blocks leaking into the ditch. The lights. The dogs.
Forty nine states will tell you a man's home is his castle. Louisiana law has always answered that a castle still has a neighbor, and the neighbor has a right to sit on his own porch.
Down here property is not a wall around you. It is a relationship with everything it touches. ⚜️
