Park Forest — Ch. 18 Art. III Housing § 18-352

(a) No fence shall be permitted in any front yard of a dwelling unit or along the front lot line of any vacant lot in a residential area, other than a living fence or decorative fence with a height not in excess of 36 inches.
(b) No fence or living fence shall be permitted in any side yard or rear yard of any dwelling unit that exceeds eight feet in height or extends beyond the front wall of the dwelling unit. Side yard fences that extend beyond the front wall of the dwelling unit shall not exceed 36 inches in height. For a corner lot, a fence or living fence less than eight feet shall be permitted in the side yard as defined in section 118-7 of the village zoning ordinance, but may extend to the front wall of the dwelling unit, as shown in illustrations 1, 2 and 3 at the end of this section.
(c) Notwithstanding subsections (a) and (b) of this section, in order to ensure vision clearance, no fence, living fence or decorative fence shall be permitted on any corner lot in excess of 30 inches in height above the elevation of the nearest adjacent curb, in an area bound by the street curblines, or pavement edge if no curbs exist, and a line connecting the curblines or pavement edges and drawn through points on the front lot lines 25 feet from their point of intersection. For corner lots having rounded property corners, the point of intersection of front property lines shall be established by extension of tangents thereto.
(d) Notwithstanding subsection (c) of this section, in order to ensure vision clearance, no fence, living fence or decorative fence shall be permitted in excess of 30 inches in height at the intersection of every driveway with a street in an area bounded by the driveway curb, or driveway pavement edge if no curb exists, the front property line, and a line connecting the driveway curb or pavement edge and the front property line drawn from points a distance of 25 feet from the point of intersection of the driveway curb and front property line, which fence, decorative fence or living fence substantially impedes vision. For rounded property lines and curvilinear driveways, the point of intersection of the front property line and driveway curb or pavement edge shall be established by extension of tangents thereto.
(e) All permitted living fences shall be properly maintained and trimmed and not permitted to extend over an adjacent sidewalk or property line.
(f) The limitations on fences, decorative fences and living fences imposed by subsections (a) and (b) of this section shall not apply and fences and living fences not to exceed a maximum height of eight feet shall be permitted at the following locations:
