Which of the following terms describes a setback distance that restricts building near property boundaries?

The term that describes a setback distance restricting building near property boundaries is the building line. A building line establishes a specified distance from a property boundary where structures cannot be placed, ensuring that buildings are set back a certain distance for various reasons, including safety, aesthetic considerations, and privacy. This regulation helps maintain uniformity in the appearance of a neighborhood, allows space for utility easements, and can prevent issues related to light and air access for neighboring properties.

Other terms in the options refer to different aspects of property lines or applicable codes. The building code encompasses regulations for the construction and design of buildings but does not directly define setback distances. The abutting line refers to the edge of a parcel adjacent to another and does not necessarily indicate setbacks. The boundary line denotes the edge of a property but does not imply restrictions on construction. The concept of a building line specifically pertains to the restrictions on how close to these boundaries a building can be constructed.
