About the Office of the City Auditor

Portland has had an elected City Auditor since 1868. The City Auditor is the sixth elected official in City government, along with the Mayor and four City Commissioners. As an auditor that is accountable to the voters of Portland, the City Auditor is administratively independent from the Mayor and other City Council members. This allows the Office of the City Auditor to audit City government departments and programs, as well as provide other services that require independence and neutrality.


As Portland’s City Auditor, Mary heads the 50-member Office of the City Auditor and its eight divisions, which are responsible for conducting performance audits of City operations, serving as the City Council Clerk, preparing the City Council agenda, managing City records and archives, providing hearings officers to adjudicate appeals of City actions, managing City elections, handling complaints against the City (through the City Ombudsman’s Office and the Independent Police Review Division), working with financing of Local Improvement Districts, and administering foreclosures of City liens on property.


Office Mission

To promote open and accountable government by providing independent and impartial reviews, access to public information, and service for City government and the public.
