Young Blonde Girl Outside Near The Wooden Fence

United States
Distinctly different land ownership and fencing patterns arose in the eastern and western United States. Original fence laws on the east coast were based on the British common law system, and rapidly increasing population quickly resulted in laws requiring livestock to be fenced in. In the west, land ownership patterns and policies reflected a strong influence of Spanish law and tradition, plus the vast land area involved made extensive fencing impractical until mandated by a growing population and conflicts between landowners. The "open range" tradition of requiring landowners to fence out unwanted livestock was dominant in most of the rural west until very late in the 20th century, and even today, a few isolated regions of the west still have open range statutes on the books. Today, across the nation, each state is free to develop its own laws regarding fences, but in most cases for both rural and urban property owners, the laws are designed to require adjacent landowners to share the responsibility for maintaining a common boundary fenceline, and the fence is generally constructed on the surveyed property line as precisely as possible.
