Setbacks are the distance required from a property line to any structure. You need to know setbacks prior to submitting a site plan to the City (for a permit)

Setbacks are measured from the structure (building, fence, wall, etc.) perpendicular to the lot line of the property. The measurement occurs at the closest point of the structure to the lot line.

Setbacks must be measured for the front, sides, and rear of the structure (applicable to a building) in relationship to the lot line.
