> The Department's highest priority for investigation and resolution of reported violations are health and safety-related. If evidence exists that a violation of Planning Code may have occurred, the Enforcement Planner sends a notice to the responsible party... High service demands can routinely cause cases to remain open for some time. These cases usually involve violations that do not constitute a significant impact.
They only process 500 complaints a year. This is not a serious problem at the scale described in the article, so local governments do not allocate resources to it.
