  • Telling the person directly is notice against trespass.
  • So is posting reasonably likely to come to the attention of intruders.
  • So is fencing or another enclosure plainly meant to keep intruders out.
  • So are purple paint marks on trees or posts, except in counties of the first and second class.

A purple paint mark is a vertical line not less than eight inches long and one inch wide, its bottom three to five feet from the ground, readily visible and no more than 100 feet from the next.

It is a defense that the building was abandoned; that the premises were open to the public and the person complied with every lawful condition on being there; or that the person reasonably believed the owner would have allowed it.
