Full Breakdown
Fence and wall height in Littleton is measured from the adjacent natural grade, not from the top of any berm or retaining feature. Front yards, and the portions of side yards in front of the building's front facade, are capped at four feet, and that portion of the fence cannot be more than 50 percent solid. Rear yards, and side yard portions behind or in line with the front facade, are capped at six feet. C, Vision Obstruction, which exists to give drivers, bicyclists and pedestrians a clear line of sight at intersections.
That section requires every corner lot and every lot at a street intersection to provide a sight triangle under City Code § 8-1-6 and AASHTO standards, bars new buildings or additions inside the triangle outright, and requires the property owner to keep the triangle as free of visual obstructions as practical between a height of two and a half feet and ten feet. Two narrow exceptions apply within the sight triangle: utility poles and traffic control devices are regulated instead by the City Engineer, and a man-made support column such as a flagpole, sign pole or utility pole is allowed if it is not more than 12 inches in diameter.
Violations & Fines
Exceeding the four-foot front-yard or six-foot rear/side-yard height cap, or obstructing a corner lot's required sight triangle, is enforced under the citywide general penalty, City Code § 1-4-1: a fine of up to $2,650, up to 364 days in jail, or up to a year of probation, with each day of continuing violation treated as a separate offense. Corner-lot sight-triangle disputes involving utility placement go to the City Engineer rather than standard code enforcement.
