For property owners, maintaining clear boundaries is a constant challenge. Traditional “No Trespassing” signs can be torn down, fade, or become overgrown. A simple, effective, and legally binding solution has emerged: purple paint. Originating from a 1987 Arkansas law, the use of purple markings on trees or fence posts is now recognized in over twenty states as an official method to post your property against trespassing.
The regulations are specific to ensure the markings are effective and legally sound. The paint must be a vertical line between 3 and 5 feet high, at least 8 inches long and 1 inch wide, and repeated every 100 feet or at major points of entry. This system provides a permanent, low-maintenance, and highly visible way to protect your land. Whether you own a large rural tract or a small wooded lot, using purple paint can be a powerful tool to secure your property rights and prevent unwanted access without the hassle of replacing damaged signs.
