Rooting out corruption, fraud, and misconduct and increasing public confidence in City government.

Office of the Inspector General

What we do

The Office of the Inspector General (OIG) works to keep City government free from fraud, corruption, and misconduct.

We conduct investigations of all government entities under the Mayor’s jurisdiction. Our Contract Compliance Unit investigates individuals or businesses that work with the City or receive City funding. It’s our job to ensure that City employees, contractors, and grant recipients follow all requirements and operate with integrity.

The OIG has the power to:

  • Issue subpoenas.
  • Examine all City documents, contracts, and monetary expenditures.
  • Demand testimony from City employees.
  • Recommend administrative discipline, policy improvements, and contract or grant action.
  • Collaborate with law enforcement on issues of criminal activity and serious cases of fraud and corruption.

Our work relies on those who report wrongdoing in City government. Those who report wrongdoing in good faith will be protected.
