What is Code Enforcement?

The City of Ontario Code Enforcement Department is responsible for enforcing Municipal Code regulations on private property throughout the city. The Ontario Municipal Code regulates parking on private property, zoning, property maintenance, and other substandard conditions on residential, commercial, and industrial properties. 

The City contracts with several other agencies to assist with enforcement of regulations. For instance, the San Bernardino County Land Use Services Department conducts weed abatement, and Animal Control is provided by the Inland Valley Humane Society. 

For more information, contact the Code Enforcement Department at (909) 395-2007.
