a.

The fire department may grant a waiver to the building inspector to approve a fence adjacent to a required ingress/egress opening of a dwelling between four and six feet if the fence has one of the following features:

i.

iv.

It is recommended that the fence be constructed off the lot line if maintenance will need to be done to the fencing without going onto the neighboring property. Hedges shall be trimmed or confined to the property on which they are planted.

7.

Height of Fences Regulated.

a.

Nonresidential.

i.

Commercial or Industrial. An industrial or commercial fence shall be no higher than eight feet in height and shall be compliant with the vision triangle height restrictions designated in Subsection H.(7)(iv) of this section. Fences may not exceed forward of the city right-of-way line. Arms or extensions which project from the fence on commercial and industrial properties shall project into the lot proper.

Six feet in height or less may be located in the side yard or along the side lot line for a distance measured from the rear lot line to any part of the lot that is at least 25 feet from the front lot line. If a house/principal structure is closer than 25 feet to the front lot line, then a six-foot high fence may be installed on any part of the lot that is as far back from the front lot line as the front of the house, except in the case of a corner lot resulting in a need for a vision triangle restriction.

iii.

Front Yard. Fences four feet or less may be located within the required front yard, except fences that are more than 50 percent solid shall not be permitted within 25 feet of the front lot line. If the house/principal structure is closer than 25 feet to the front lot line, then the four-foot fence height limitation applies only to the area between the front plane of the house and the front property line.

iv.

Vision Triangle. Exception for corner lot properties requiring intersection sight distance. Fences may only be a maximum of 30 inches in height and be no more than 30 percent solid, when located in the vision triangle as described in Subsection C. of this section.

I.

Fences to Be Repaired and Maintained. All fences shall be maintained and kept safe and in a state of good repair and the finished side or decorative side of a fence shall face adjoining property. Hedges shall be trimmed and maintained at a height that does not violate the height restrictions for its permitted location.

J.

Nonconforming Fences. Any fence existing on the effective date of this Code and not in conformance with this section may be maintained, but no alteration, modification, enlargement, extension, replacement or improvement of the fence shall be made except in strict compliance with all the requirements of this chapter.
