Which of these describes a fixture? A fixture is described as an item that is permanently attached or fixed to a building or property, considered part of real estate, requiring tools to remove, and intended to stay with property when sold. Describing a fixture, it is attached to wall, floor, or ceiling by nails, screws, glue, plumbing, or wiring, adapted to property use, and not easily movable without damage. Examples that describe fixture include built in lighting, ceiling fan, sink, toilet, bathtub, built in bookshelves, window blinds screwed in, and door knobs. Non fixtures are personal property like freestanding furniture, rugs, curtains hung on tension rod, and portable lamps. Legal description of fixture includes annexation, adaptation, and intent. So description of fixture is something attached permanently to home and considered part of house, not personal movable item, so it stays when house sold, unlike personal property that seller takes.
