About the Auditor

Portland has had a City Auditor since 1868, and the position has been elected by voters since 1891. As the sixth elected official in Portland’s government, the Auditor is functionally independent of City Council and accountable only to the public.

The Auditor’s Office has an $11.2 million operating budget. Fifty-two employees carry out their work in five divisions. Those primarily responsible for ensuring the City is accountable are Audit Services, Independent Police Review, and the Ombudsman. The divisions responsible for ensuring the City is transparent are Archives and Records Management and Council Clerk/Contracts within the Operations Management. Other staff in Operations Management oversee City elections and the lobbyist registration program in addition to providing support to all divisions in the Auditor’s Office.
