Fences, whether built as part of a subdivision or added thereafter, shall be maintained in sound condition and good repair. Fence posts shall be kept in a vertical position, and rails shall be kept in a horizontal position. Fence posts and rails with evidence of significant rot or deterioration must be replaced to keep the fence safe and prevent catastrophic failure. Fence posts and rails that lean or sag more than 15 degrees will be considered to be in violation of this section. Missing fence boards must be replaced within 30 days, unless dogs are kept inside a fenced yard, in which case missing boards must be replaced immediately. Fences of weather-resistant wood, such as redwood or cedar, need not be painted or stained, but if paint or stain is applied, it must be maintained free of peeling, bubbling or flaking.
