Okay kiddo, let me explain the term ‘setback’ to you. Imagine a house or a building which is located on a piece of land. Now, setback is the distance between the building and the nearby street, boundary, or neighboring property.
The reason why setback is important is to ensure that there is enough space between the building and everything else nearby. This space is important for safety reasons such as preventing the building from catching fire and allowing enough space for emergency vehicles to get through.
Setbacks are usually set by law or zoning regulations, and they vary from place to place. Some cities or towns may require lesser setbacks in certain areas, whereas others may require larger ones in more urban areas.
So, to sum it up, a setback is the required distance between a building and the surrounding things to ensure safety and compliance with laws and regulations.
