Skip to content The Purple Paint Law allows property owners to mark their land boundaries with purple paint instead of traditional “No Trespassing” signs. This law is recognized in at least 18 U.S. states, including Texas, Arkansas, Missouri, North Carolina, Illinois, and Florida. It is especially common in rural areas with large properties such as farms, ranches, and timberland.
How the Purple Paint Law Works
While details vary by state, most laws require the following:
-
Paint marks must be vertical
-
Marks are usually 8 to 12 inches long
-
They must be placed 3 to 5 feet above the ground
-
Marks are spaced every 100 to 1,000 feet along the property boundary
-
The color must be purple, often referred to as “blaze purple”
In states like Texas, purple paint carries the same legal authority as a posted sign.
