Structural encroachment is a big word that means something is getting too close to another thing and might cause damage or problems.
Think about it like this - imagine you have a big toy castle and you want to build a wall around it to protect it from other toys. But, if you build the wall too close to the castle, it might bump into the castle and knock it down, or cause parts of the castle to break off.
Now, think about a building in real life. When one building gets too close to another building or property, it is called "structural encroachment." This can happen when a building is built on a property line, or when parts of the building extend beyond the limits of the property it's on.
Just like our toy castle example, structural encroachment can cause problems for both the building encroaching and the one being encroached upon. It can cause damage to the structures themselves, and can create legal disputes between the owners of the buildings or properties.
So, it's important to make sure that buildings are built far enough away from each other and within the limits of their property lines to prevent structural encroachment and keep everything safe and sound!
