There are over 200 violations that are reported in the 311 system that affect the quality of neighborhood life. The most common are high weeds, litter, junk motor vehicles, and bulky trash. Some are more health related like mosquitoes. Others are environmental such as water conservation. The annual volume of reported code violations is approximately 200,000 annually. For the purpose of this data set, cases are grouped into four categories: structure, nuisance, zoning and other.

Activities are actions taken by code staff regarding violations reported. They are grouped into four categories: complaints, investigation and resolution. When a complaint is received it is assigned to an inspector who visits the location and determines if there is a violation. If found, the property owner is notified and ask to correct the problem. If the problem persists, the property owner can receive a citation; or the city will abate the violation and charge the owner for the cost of the services. Either way, violations are eventually abated.
