In a zoning context, what does the term "setback" refer to?

In a zoning context, the term "setback" specifically refers to the distance a building must be from the property line. This regulation is crucial in urban planning as it ensures that structures have sufficient space around them for various reasons, such as safety, aesthetic considerations, and providing access to light and air. Setbacks help maintain uniformity in the development of properties, contribute to the overall character of a neighborhood, and facilitate the movement of people and vehicles.

The other options involve different aspects of zoning and land use regulations: maximum height limits pertain to how tall buildings can be, minimum lot size requirements deal with the size of parcels needed for development, and materials specifications relate to building codes that dictate the acceptable materials for construction to ensure safety and performance standards. However, none of these definitions directly capture the essence of what a "setback" signifies in the zoning context.
