Berwyn, IL Fence Regulations: Neighbor Fence Rules (2026)

Section 1244.04(C)(6)(a) of the Berwyn Code of Ordinances controls where a fence goes relative to the neighbor. Fences and walls, including all posts, bases and other structural parts, must be located completely within the boundaries of the lot on which the fence is located. A fence centered on the property line puts half of its posts and bases on the adjoining lot, and the text does not allow that. Each owner builds on his or her own side.

The second-fence clause closes off a common boundary dispute. Under (C)(6)(a)3, a second fence may not be attached or installed parallel to an existing fence at the same lot line. If the neighbor already has a fence on the line, the code does not let you add a second one alongside it or fasten a new one to it. Section (C)(6)(c)3 adds that the finished side of a fence or wall shall face outward from the lot, so the neighbor and the street see the good face and the posts and rails face inward.

The yard rules also shape what the neighbor sees. Fences and walls are prohibited in the front yard. They are allowed in the interior side and rear yards and setbacks, and in the corner side yard and setback between the principal structure's rear facade and the rear lot line. The maximum height is six feet, measured from the ground at the base. A residential lot directly adjacent to, or across an alley from, a Commercial or Industrial District can erect a solid fence or wall in the rear yard up to six feet, including any decorative open trellis.

Every fence needs a building permit, because Table 1244.04-A marks Fence or Wall with a "B" in all ten districts. Residents who need relief from height or placement rules go to the Commission, where § 290.07(B) sets a $75 filing fee for a residential fence in a Residence District, plus the cost of publishing notice.
