DOI's Inspectors General

DOI is the City’s independent Inspector General, with oversight of City elected officials, employees and contractors and those who receive benefits from the City. City personnel can and must report corruption-related issues to DOI. DOI’s Inspectors General (IG) oversee squads of investigators, auditors and lawyers who are responsible for investigating the affairs, functions, accounts, methods, personnel or efficiency of City agencies. 

DOI investigates corruption, fraud and financial abuse involving the City, identifies corruption vulnerabilities and recommends reforms to improve City operations. DOI’s structure has evolved over its more than 140-year history to respond to ever-changing corruption hazards. A series of reforms in the 1970s and 1980s strengthened DOI’s ability to conduct independent investigations. Today, the DOI Commissioner has more than a dozen Inspectors General reporting to him. DOI’s IG offices include the newly-established Office of the Inspector General for Health + Hospitals and the Office of the Inspector General for the NYPD. Collectively, DOI’s IGs have cracked numerous corruption-related cases from large-scale bribery schemes to theft of taxpayer dollars. Since 1990, DOI has arrested more than 10,700 individuals for corruption and fraud-related offenses and more than 3,500 recommendations from DOI have been adopted by the City.
