Chapter 17.44 GENERAL REGULATIONS

The general provisions and standards contained in this chapter apply to all uses and structures in all zone districts, unless otherwise specifically stated. (Ord. 815 § 3 (Exh. A), 2020; Ord. 635 § 1, 2003).

17.44.020 Nonresidential buildings.

All nonresidential buildings and structures must have been originally and specifically constructed for use as a permanent building or structure. Cargo containers, truck vans, converted mobile homes and similar prefabricated containers and structures originally built for other, alternative purposes do not meet these criteria and are prohibited for use as accessory buildings. (Ord. 815 § 3 (Exh. A), 2020; Ord. 635 § 1, 2003).

17.44.030 Yards.

A. No yard shall be reduced in size or area below the minimum dimensions required by this title except as allowed by variance.

B. No portion of any principal building or structure over 42 inches above the finished grade shall extend into a required yard except as provided elsewhere in this title.

C. The required front yard may be reduced by the administrator for a primary residential dwelling and accessory if the following apply:

1. The front yard may be reduced to 20 feet from the road right-of-way or 50 feet from the deeded centerline of the road, whichever distance is greater, when the front 50 feet of the lot equals or exceeds an average of one foot of fall/rise in seven feet of distance from the front lot line.

2. The front yard may be reduced to 15 feet from the road right-of-way or 45 feet from the deeded road centerline, whichever distance is greater, when the front 50 feet of the lot equals or exceeds an average of one foot of fall/rise in four feet of distance from the front lot line.

3. The front yard may be reduced to 12 feet from the road right-of-way or 42 feet from the deeded road centerline, whichever distance is greater, when the front 50 feet of the lot equals or exceeds an average of two feet of fall/rise in five feet of distance from the front property line.

4. The front yard may be reduced if a residential dwelling(s) located on an immediately abutting or adjoining lot(s) has a front yard of less than the required depth for the district. The required front yard in these instances is determined by averaging the front yard(s) with less than the required depth and the front yard requirement of the district. The front yard setback required in the district shall be used in calculating the setback for an abutting or adjoining lot in the following circumstances:

a. Where no residential dwelling exists on a lot(s) adjacent to the lot proposed for development;

b. Where a residential dwelling exists on a lot(s) adjacent to the lot proposed for development and the existing residential dwelling(s) is (are) located at a depth greater than the front yard requirement of the district.

5. If the front yard requirement is to be reduced under the conditions specified in this subsection, all driveways and entrances to garages and carports entering onto a road with a reduced setback shall be parallel or nearly parallel to the road by providing an area or hammerhead for a turnaround in order to avoid the backing of vehicles directly onto the road, and to allow vehicles to be completely outside of a structure before entering the established road right-of-way.

a. In all cases the setback or approaches allowed under these exceptions shall be approved by the administrator in order to ensure safe travel on adjoining roads and streets; and

b. The natural grade of the lot shall be maintained as much as possible.

D. Xeriscaping and other forms of low water use landscaping are encouraged versus large lawn or other landscaped areas that routinely require overage charges. (Ord. 815 § 3 (Exh. A), 2020; Ord. 635 § 1, 2003).
