and Building Design Standards

25.175.010 Purpose.

The purpose of this chapter is to establish certain basic development requirements in order to realize the community’s goals and objectives. These are minimum standards which must be met to assure land use compatibility and promote public health, safety and welfare. Further, it is the purpose of this chapter to achieve particular objectives, including, but not limited to, the following:

(1) Ensure attractive, functional residential development to meet the City’s housing needs.

(2) Provide prominent, welcoming and clearly defined entrances to the site and to buildings to allow developments to be easily visible and accessible from the street, and provide wayfinding features.

(3) Enforce the physical and visual connection between the buildings, streets, and open space in order to create a safe, lively and pedestrian-friendly environment.

(4) Enhance the streetscape environment to foster a safe streetscape for all users regardless of abilities, including people driving, walking, biking, or taking transit.

(5) Provide open space that is safe and usable for the residents, landscaped in a way that enhances visual and environmental quality of the neighborhood.

(6) Ensure personal safety and security and establish lighting that is compatible with the development, and reduce adverse impact of lighting to the surrounding areas.

(7) Minimize visual and other impacts of waste and service handling facilities; ensure that utilities such as carports, storages, mailboxes, trash receptacles, electric and mechanical equipment do not create any physical and visual hazard for the residents.

(8) Allow for flexibility of development while maintaining compatibility within the City’s various neighborhoods. [Ord. 4700A § 16, 2023; Ord. 3354 § 2, 1999; Code 1970 § 25.74.010.]

(1) Variable Yard Requirements. The City Council, on recommendation of the Planning Commission, and after a public hearing held by the Planning Commission, may establish a building line along certain streets throughout certain zones or throughout certain natural areas, other than the setback requirements as established herein, when it is found that to do so will protect public health, welfare and safety;

(a) Eaves, cornices, belt courses, and similar ornamentation may project into the setback not more than two feet;

(b) Steps, platforms, and open porches may extend into the rear yard setback, but not more than four feet;

(3) An open or enclosed porch shall be considered part of a building in the determination of the front yard setback and lot coverage;

(4) 

(a) Where two contiguous corner lots, or two lots separated only by an alley, form the entire frontage between two parallel streets and there is erected a solid six-foot fence, permitted accessory buildings may be located not closer than five feet from the property line along the street on which there is a solid six-foot fence. This reduced setback shall not apply to garages or accessory buildings higher than 10 feet.

(b) Where two contiguous corner lots form the entire frontage between two parallel streets, the front yard along the common flanking street shall be reduced to 15 feet. This reduction shall not apply to garages that are accessed from the flanking street.
