Which of the following is typically considered a fixture?

The correct answer is plumbing, as it is generally considered a fixture because it is permanently attached to a building's infrastructure. Fixtures are items that are affixed to a property in such a way that they typically cannot be removed without causing damage to the property. Plumbing, including pipes, toilets, and sinks, is integrated into the structure of the building and functions as a critical component of the property's systems.

On the other hand, appliances, paint, and furniture do not usually meet the criteria for fixtures. Appliances are often considered personal property rather than real property because they can be removed without damaging the structure. Paint is a superficial application, and while it may be attached to the walls, it is not a permanent feature that is typically included in the sale of a property. Furniture is entirely movable and not attached to the property in any permanent manner, which clearly separates it from fixtures like plumbing that are essential to the function of the building itself.
