Welcome to the Orange County Comptroller Website

The Comptroller is an elected official answering directly to the citizens of Orange County and serves as a check and balance for the public in the use of County resources. This results in heightened levels of transparency, the protection of public assets, and the greatest accounting integrity possible.

Services performed by the County Comptroller can be classified into three broad categories: Financial, Audit, and Records Administration. The Comptroller’s specific roles include serving as chief financial officer, county auditor, Clerk of the Board of County Commissioners, recorder of official records, and custodian of county funds and records.

Our goal is to make information easily available to citizens, and we welcome comments & suggestions on ways we can serve you better.
