Full Breakdown
Under the Allen County Zoning Ordinance, a hedge or retaining wall not exceeding 3 feet in height above the grade of the adjoining sidewalk or ground may be located in the required front yard with no minimum setback, as an exception to fence and wall standards. On corner lots without a platted build line, a retaining wall up to 3 feet has no setback requirement, but no wall may impede vision within the corner visibility area between heights of 3 and 8 feet. Retaining walls taller than 3 feet must meet the applicable yard setbacks, and structural walls may require a separate building permit through the Building Department.
Violations & Fines
A wall placed in a required setback or blocking corner sight lines is a zoning violation; correction or removal may be ordered by DPS.
