What term describes the action taken to secure a vacant building from unauthorized access?

The action taken to secure a vacant building from unauthorized access is known as board-up installation. This process involves placing boards or other barriers over windows, doors, and other openings to prevent intruders from entering the property. It is essential for maintaining safety and security, particularly in vacant buildings that may be at risk for vandalism, theft, or squatting. Proper board-up installation not only protects the physical integrity of the structure but also helps mitigate liabilities for property owners.

While property preservation also relates to securing and maintaining buildings, it encompasses broader activities that might include upkeep and maintenance tasks beyond simply securing access points. Building stabilization refers to actions taken to ensure that a building remains structurally sound, which does not specifically address unauthorized access. Board-up removal would be the opposite process, involving taking down the barriers that were installed for security. Thus, board-up installation is the most accurate term for the action taken to secure a vacant building from unauthorized entry.
