5-3-4: YARDS:
   A.   Front Yards: Every permanent structure with the exception of signs, fences and walls on all properties which front on an established street right-of-way shall be set back from the front property line at least twenty five feet (25'). For sign setbacks, see chapter 11 of this title for the sign regulations. Note: More restrictive setbacks may be required due to noise and vibration.
   B.   Rear Yard: Every permanent structure with the exception of signs, fences and walls shall be set back at least ten feet (10') from the rear property line, except the rear yard of a corner lot that fronts a public right-of-way shall be not less than twenty five feet (25') along the side or flanking street. If the rear yard abuts a lot in a different district that requires setbacks for rear yards, then the property in this district shall have setbacks as specified in the more restrictive district. Note: More restrictive setbacks may be required due to noise and vibration.
   C.   Side Yards: No setback for structures shall be required on side property lines, unless required by the International Building Code or International Fire Code and except on the side yard of a corner lot which fronts a public right-of-way shall be not less than twenty five feet (25') along the side street, also if the side yard abuts a lot in a different district which requires setbacks for side yards, then the property in this district shall have setbacks as specified in the more restrictive district. Note: More restrictive setbacks may be required due to noise and vibration.
   D.   Nonconforming Structures: Existing structures that met setback requirements when they were constructed but no longer meet setback requirements as a result of right-of-way dedication or eminent domain procedures shall be considered legal, conforming structures unless there is a health and safety issue as determined by the City Engineer or the Fire Marshal.
