Building layout uses measurements from property lines called ___ distances.

Building layout uses measurements from property lines called ___ distances.

• A. Frontage distances
• B. Boundary distances
• C. Setback distances
• D. Orientation distances

Answer: (C)

Setbacks are the minimum distances a building must be set back from property lines, as required by zoning and building codes. This concept governs where the footprint can sit on a lot, ensuring adequate space for light, air, drainage, fire safety, and access around the structure. Front, side, and rear setbacks are specified by local regulations, so they guide the overall layout of the building on the site. The other terms don’t fit because they aren’t the standard way to describe required clearances from property boundaries; frontage relates to street-facing width, orientation deals with direction, and boundary distances isn’t the established phrasing used in codes.
