This section establishes standards to ensure the provision of open areas around structures for: visibility and traffic safety; access to and around structures; access to natural light, ventilation, and direct sunlight; separation of incompatible land uses; and space for landscaping, privacy, and recreation.
A. Setback Requirements.
1. All structures shall conform with the setback requirements established for each zoning district by Article 19-2 (Zoning Districts and Allowable Land Uses), Tables 2-3 and 2-6, and with any special setbacks established for specific uses by this section or by Chapter
19.36 (Standards for Specific Land Uses).
2. Any portion of a structure, including eaves or roof overhangs, shall not extend beyond a property line or into an access easement or street right-of-way, except where approved by the Director of Public Works.
3. Each required setback area shall be open and unobstructed from the ground upward, except as provided in this section.
B. Exemptions from Setback Requirements. The minimum setback requirements of this Zoning Ordinance apply to all structures and uses except the following:
1. Fences or walls in compliance with Section
19.20.050 (Fences, Walls, and Hedges);
2. Decks, free-standing solar devices, steps, terraces, and other site design elements placed directly upon the finished grade, that do not exceed a height of 12 inches above the surrounding finished grade at any point; and
3. Retaining walls up to 42 inches in height above finished grade.
C. Measurement of Setbacks. Setbacks shall be measured as follows. See Figure 3-4.
1. Front Setbacks. The front setback shall be measured from the point of the front property line of the parcel nearest to the wall of the structure, establishing a setback line parallel to the front property line, except as follows, and except as provided by subsection (C)(6), below.
a. Corner Parcels. The measurement shall be taken from the point of the structure nearest to the property line adjoining the street on which the property has the shortest frontage and from which access to the property is taken. The Community Development Director may approve an alternate primary frontage of corner parcels only when the Community Development Director finds on-site or adjacent conditions to be incompatible with the standard primary frontage and an alternate primary frontage will improve the site plan (including, but not limited to, the location of the setbacks, the location of building footprint, utilities, parking, and ingress/egress). See also subsection (C)(6), below.
b. Flag Lots. The measurement shall be taken from the point of the wall of the structure nearest to the point where the access strip meets the bulk of the parcel; establishing a setback line parallel to the front property line that extends from the access strip to the side property line farthest away. See Figure 3-5.

FIGURE 3-5 Flag Lot Setbacks |
2. Side Setbacks. The side setback shall be measured from the point on the side property line of the parcel nearest to the structure, establishing a setback line parallel to the side property line, that extends between the front and rear yards. See also subsection (C)(6), below.
3. Street Side Setbacks. The side setback on the street side of a corner parcel shall be measured from the point of the side property line that adjoins the street right-of-way nearest to the structure. See also subsection (C)(6), below.
4. Rear Setbacks. The rear setback shall be measured from the point on the rear property line of the parcel nearest to the structure, establishing a setback line parallel to the rear property line, that extends between the side property lines, except as follows, and except as provided by subsection (C)(6), below:
a. If an access easement or street right-of-way line extends into or through a rear yard, the measurement shall be taken from the point of the easement or right-of-way line nearest to the structure;
b. Where the side lot lines converge to a point, a line five feet long within the parcel, parallel to and at a maximum distance from the front lot line, shall be deemed to be the rear lot line for the purpose of determining the depth of the required rear yard; and
FIGURE 3-6 Rear Setback for Irregular Lot |
c. In determining the depth of a rear yard of a structure, where the rear yard adjoins an alley, one-half the width of the alley up to 10 feet, may be considered as a portion of the rear yard. This provision shall not reduce the depth of any residential rear yard to less than 15 feet from the property line; provided that the door of a structure, except a fence, that opens into an alley, shall not be established closer than 15 feet from the center of the alley.
5. Nonparallel Lot Lines. Where a structure wall is not parallel to a side or a rear lot line, the required dimension of the side or rear yard along the line may be averaged; provided that the resulting side yard shall not be less than three feet in width, and the rear yard shall not be less than 10 feet in depth, at any point.
6. Location of Setbacks on Corner Parcels Combined with Interior Parcels. When one or more interior parcels is combined with a corner parcel, the location of the front, side, and rear yards of the interior parcels shall be maintained as they existed before the parcel combination (lot tie) occurred.
D. Limitations on Uses of Setbacks. Required setback areas shall only be used as follows.
1. Structures. Required setback areas shall not be occupied by structures other than:
a. Structures that are exempted from setback requirements by subsection
(B);
b. Residential accessory structures located within setback areas in compliance with Section
19.36.300 (Residential Accessory Uses and Structures); and
c. The projections into setbacks allowed by following subsection
(E) 4. Storage. Front or street side setbacks shall not be used for the storage of scrap, junk, automobiles, boats, habitable trailers, utility trailers, similar vehicles, or equipment. This restriction includes the storage of operable or inoperable vehicles except on a paved driveway leading to a garage or carport.
E. Allowed Projections into Setbacks. Architectural features attached to the primary structure may extend beyond the wall of the structure and into the front, side, and rear setbacks as provided by Table 3-2, but shall project no closer to a property line than the minimum separation required by Table 3-2. See also Figure 3-7. See Section
19.36.300 regarding detached residential accessory structures.
F. Setback Requirements for Specific Structures.
1. Hot tubs, Swimming Pools, Spas, and Other Water Elements. Swimming pools, hot tubs, spas, and similar water elements intended for human occupancy may be allowed within a required rear setback, provided that it is located no closer than five feet to any property line. Ponds and other water elements not intended for active recreation and that do not exceed a height of 18 inches may be placed within any required setback.
2. Retaining Walls. (Retaining walls less than 42 inches in height above finished grade are exempt.)
a. Up to Six Feet. Retaining walls from 42 inches to six feet in height may be located within a required setback provided the exposed side of the wall faces into the subject parcel.
b. Over Six Feet. Retaining walls greater than six feet in height, or where the exposed side of the wall faces out from the subject parcel without regard to height, shall be subject to the same setback requirements as the primary structure.
