1. Front yard setback. The front of any building constructed on any parcel 200 feet or more in depth from the adopted right-of-way line of Lake Mary Boulevard shall be set back a minimum of 60 feet. For properties that are less than 200 feet from the adopted right-of-way line of Lake Mary Boulevard, the front yard setback shall be 40 feet.
2. Side yard setbacks. Eight feet on the narrowest side, with the combined setbacks equaling 20 feet.
3. Side yard setbacks for flag lots = 20 feet.
4. Rear yard (residential). Thirty feet from the rear property line or 75 feet above the mean high water elevation, whichever is greater.
