The Office of the Chief Integrity Officer was established in 2008. It plays a critical role in City government. Throughout the executive and administrative branch, the office promotes:

  • Honesty.
  • Integrity.

In this role, our office:

  • Ensures the City’s day-to-day operations are conducted openly, fairly, and on a level playing field.
  • Creates and supports a compliance program to proactively identify and prevent wrongdoing.
  • Provides individualized and confidential guidance on City ethics laws and policies, including the mayor’s executive order on gifts.
  • Offers ethics education through training and communications.

Ethics rules may change to reflect advances in technology or best practices. Maintaining a strong culture of ethics is a bedrock of the Chief Integrity Office and the mayor’s administration. Taxpayers deserve no less.
