Penn Hills requires a clear sight triangle at street intersections. Fences, hedges, and walls over 30 inches prohibited within the triangle measured 25 ft along each curb line.
Under Penn Hills Zoning Chapter 27, corner and intersection lots must maintain a clear sight triangle to protect motorist and pedestrian visibility. The triangle is typically formed by measuring 25 feet along each curb/street line from their intersection and connecting the endpoints. Within that triangle, no fence, hedge, wall, sign, shrub, or other obstruction exceeding 30 inches in height above the adjacent street grade is allowed. The rule also applies at driveway-street intersections on busier corridors. PA Vehicle Code 75 Pa.C.S. 3353 separately prohibits parking in a manner that obstructs sight at intersections. Violations are treated seriously because they contribute to T-bone accidents; Code Enforcement can issue immediate correction orders in addition to citations, and repeat offenders face daily fines until the obstruction is removed.
Sight-triangle violation: $100-$500 first citation, plus mandatory removal. Daily fines continue until corrected. Related traffic-obstruction citations under PA Title 75 possible if parked vehicle is involved.
