Oak Lawn requires fences to be installed with the finished (smooth) side facing the neighboring property. Oak Lawn does not mediate private boundary disputes, which are civil matters governed by Illinois property law.
Oak Lawn's fence ordinance requires that the finished side of any fence, meaning the smooth side without exposed posts and stringers, face outward toward the neighboring property and any public right-of-way. Both sides of double-sided fencing satisfy this rule. The village does not require neighbor notification or consent before installing a fence, but it is considered best practice to discuss placement with adjoining property owners. Disagreements over the exact property line, encroachment, or shared maintenance of boundary fences are civil matters and must be resolved between owners, typically starting with a licensed surveyor and then private legal counsel. Illinois has no statewide 'good neighbor' fence cost-sharing statute, so adjoining owners are not automatically required to split costs. Contact the Building Department at (708) 499-7830 for code questions only.
Fences installed with the rough side facing outward may receive correction notices requiring reinstallation with the correct orientation, with fines of $50 to $200 for non-compliance. Encroaching fences must be removed or relocated by the owner; failure to do so may result in civil lawsuits from neighbors.
