19.20.050 Development Standards for Residential Zones.
A. Purpose: This section establishes the site requirements and development standards for uses in the residential zones. The standards and rules are established to provide flexibility in project design, prevent fire danger, provide adequate access and circulation, reduce incompatibilities, and prevent overloading of infrastructure due to the impacts of development.
B. Explanation of table: Development standards are listed down the left column of the table and the residential zones are identified across the top row. The matrix cells contain the requirements of each zone. The footnotes identify particular requirements applicable to a specific use, standard, or zone.

Footnotes for Table 2
3.Setbacks
A.Within the setback area shown in Table 2, no building or structure (as defined in Chapter 19.06) shall be allowed, except flagpoles, signage, fencing, slope stability structures, and open steps and platforms having no roof covering. Eaves, cornices, and awnings may project into the required setback no more than two feet (2').
B.The setbacks shown in the table are zoning setbacks. Larger setbacks may be required by the State Building Code, State Fire Code, sight distance requirements, or landscaping requirements (Chapter 19.57).
C.There shall be no side yard setback requirement for single family dwelling units sharing a common wall or attachment when each dwelling is on its own lot of record.
D.To determine the interior side setback requirement in the R-1 and R-2 zones, the lot width shall be measured at the front setback line for rectangular lots. For all other lot shapes, the average of the width at the front setback line and rear setback line shall be used to calculate the required interior side setback.
4.Except that residential structures in the R-1 and R-2 zone may conform to existing structures within two hundred feet (200') along either street but in no case shall a building be permitted less than fifteen feet (15') from a property line abutting a street.
5.Lawfully existing structures built prior to the adoption of this ordinance shall not be required to comply with this setback. Building permits for lots in subdivisions approved prior to the adoption of this ordinance shall not be required to meet this setback. Subdivisions approved after the adoption of this ordinance and the request for building permits on lots in these subdivisions shall meet this setback.
6.Open space shall not include parking areas or driveways and shall be usable outdoor area for recreation and landscaping. The smallest dimension of the open space area shall be not less than fifteen feet (15'). Open space need not exceed five thousand (5000) square feet total.
7.The following structures are exempt from the building height restriction and may be erected higher than thirty feet (30') so long as the structure permitted is a distance from all property lines not less than its height and it meets any additional conditions as noted:
A.Church spires, steeples, and bell towers. Other portions of a church building may exceed thirty feet (30') if addressed as part of the conditional use permit for the building.
B.Flag poles.
C.Non-commercial antennas and towers related to wireless transmissions and relays, if permitted by law, so long as those towers are no higher than necessary to reasonably accommodate the use including the use of the shortest structure possible and crank-up or telescoping devices are used whenever possible.
D.Water reservoirs.
8.A primary structure may be constructed up to thirty-five feet (35') in height under the following conditions:
A.The interior side yard setback must be at least ten feet (10') with one additional foot of setback for each additional foot of building height over thirty feet (30').
B.A minimum lot size of twelve thousand five hundred (12,500) square feet.
9.A primary or accessory structure may be constructed up to thirty-five feet (35') when the interior side yard setback is increased by one foot (1') of setback for each additional foot of building height over thirty feet (30').
10.In a garage or carport constructed to the standards of the State Building Code.
