Building Setback Distance from Property Line The values of the setback, bend allowance, and bend deduction can be calculated from the sheet thickness, bend radius, bend angle, and K-factor.

Below you can see how these values become very large compared to the part itself as the bend approaches a flat. NOTE: The garage can utilise the side setback control, while the remainder of the house must be setback as per the rear setback control.
