Corner lots must maintain a clear vision triangle, typically 25 feet by 25 feet at intersections, with nothing over 30 inches tall. AMC Title 21 enforces this strictly, especially given winter snow berms.
AMC Title 21.07 requires a vision clearance triangle at every street-to-street intersection and at driveways entering collector or arterial streets. The standard residential triangle is 25 feet measured along each property line from the corner, with no fence, hedge, sign, or structure taller than 30 inches above street grade inside that area. Arterial and collector intersections may require larger triangles. In winter, plowed snow berms compound visibility issues, and the Municipality may require reduced-height or more transparent fencing (wrought iron, open-picket) on corner lots. Violations are typically identified during building inspection, neighbor complaint, or after a traffic incident.
Notice to abate, typically 30 days to comply. Failure leads to removal at owner cost plus $250 to $500 citation.
