St. Louis corner lots must maintain a sight-triangle with fences, hedges, and vegetation no taller than 3 feet within 25 feet of street intersections under SLRC 17.44.020. Violations create traffic hazards and trigger abatement orders.
St. Louis Revised Code 17.44.020 establishes a clear sight-triangle at all street and alley intersections. Within 25 feet of the corner measured along both curb lines, no fence, wall, hedge, shrub, sign, or other visual obstruction may exceed 3 feet in height above the street grade. Tree trunks are exempt provided lowest branches are pruned to at least 8 feet above grade. The restriction applies to all properties including residential, commercial, and institutional. St. Louis Streets Department and SLMPD Traffic Division enforce, particularly at intersections with crash history. Neighborhood traffic calming initiatives in areas like Tower Grove, Shaw, and the Central West End have increased attention to sight-line compliance. Violations generate a 14-day notice to trim or remove; non-compliance results in city abatement at the owners expense plus a $200 fine and a lien on the property.
