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 [[Spain|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. More recently, fences are generally constructed on the surveyed property line as precisely as possible. Today, across the nation, each state is free to develop its own laws regarding fences. In many cases for both rural and urban property owners, the laws were designed to require adjacent landowners to share the responsibility for maintaining a common boundary fenceline. Today, however, only 22 states have retained that provision.

Some U.S. states, including [[Texas]], [[Illinois]], [[Missouri]], and [[North Carolina]], have enacted laws establishing that [[purple]] paint markings on fences (or trees) are the legal equivalent of "[[Trespass|No Trespassing]]" signs. The laws are meant to spare [[landowners]], particularly in [[rural]] areas, from having to continually replace printed signs that often end up being stolen or obliterated by the elements.<ref>{{cite web |date=7 Sep 2016 |author=Dan Evon |website=Snopes |title='Purple Paint' Trespass Warning |url=https://www.snopes.com/fact-check/purple-paint-no-trespassing/}}</ref>
