Summary
Norwalk caps a solid wall, fence or hedge at six feet anywhere on a lot under Municipal Code Section 17.03.300(A), but drops that limit to 42 inches in the required front setback and to 30 inches inside a corner-lot vision-clearance triangle defined by Section 17.03.250. The Director of Community Development can approve taller open fencing case by case.
A. A solid wall, fence, or hedge up to six feet in height may be located anywhere on a lot or parcel, except within the required front setback area, where the height is restricted to 42 inches, and except within a corner cut-off area, where the height is restricted to 30 inches as prescribed in Section 17.03.250.
Full Breakdown
Section 17.03.300, titled 'Height limitations for walls, fences and hedges,' sets three different height ceilings depending on where the fence sits on the lot. Subsection A allows a solid wall, fence or hedge up to six feet in height anywhere on a lot or parcel as the general rule, but it carves out two lower limits: within the required front setback area, height is restricted to 42 inches, and within a corner cut-off area, height drops further to 30 inches as prescribed in Section 17.03.250.
That corner cut-off cross-reference points to Section 17.03.250's vision-clearance rule: every corner lot must maintain a triangular cut-off at the street intersection, formed by a diagonal line drawn between two points 17 feet along the front and side lot lines from where they meet. Within that triangle, no tree, fence, shrub or other physical obstruction higher than 30 inches above the established curb grade is permitted, though the City Engineer can waive or modify the restriction if the obstruction will not create an unreasonable traffic hazard.
Section 17.03.300(B) gives the Director of Community Development discretion to approve exceptions to the general height scheme: an open, non-view-obscuring fence may exceed the front-setback or corner-cutoff limits, or a solid wall, fence or hedge may exceed six feet elsewhere on the lot, if the Director finds it will not adversely affect public health, safety or general welfare.
Violations & Fines
A solid fence, wall or hedge built taller than six feet on the interior of a lot, taller than 42 inches in the required front setback, or taller than 30 inches inside the corner vision-clearance triangle violates Section 17.03.300(A) unless the Director of Community Development has granted an administrative exception under subsection B. A wall or fence over six feet built without the required building permit is separately noncompliant under subsection C.
