Multnomah County Campaign Finance & Disclosure Information


Multnomah County Candidate elections are subject to campaign finance requirements first adopted by voters in 2016 through a Charter amendment.  As implemented, those requirements limit the amount and source of campaign Contributions to Multnomah County Candidates and require that Communications advocating for or against Multnomah County Candidates clearly disclose who paid for them.

These campaign finance regulations apply to all Candidates for:

  • Multnomah County Chair
  • Multnomah County Sheriff
  • Multnomah County Commissioner
  • Multnomah County Auditor

Multnomah County Code (MCC) 5.200 - 5.205 and Contribution Limit and Disclosure Administrative Rules (CLDR) (170.34 KB) implement the County’s campaign finance regulations. Legally defined campaign finance terms are capitalized and the complete list of definitions are included in CLDR for your reference.

Contribution Limit Overview

Multnomah County Candidates and their Candidate Committees are only allowed to accept Contributions from Individuals and from Political Committees.

Candidates are only allowed to accept $568 or less from an Individual or Political Committee during a Multnomah County Candidate Election Cycle. The exception to this is for Contributions from Small Donor Committees, which are Political Committees that do not accept Contributions from Entities and do not accept more than $115 from Individual contributors within a calendar year. Candidates are allowed to accept unlimited Contributions from Small Donor Committees. 

Candidates and their Candidate Committees are not allowed to accept Contributions directly from any other Entities, which include corporations, limited liability companies, unions, and nonprofit organizations, among others. However, those Entities may form Political Committees, including Small Donor Committees, that can contribute to Multnomah County Candidates.

Both Candidates and contributors are responsible for complying with the Contribution limits. In the event that a Contribution violates Multnomah County’s Contribution limits, both the Candidate and the contributor may be liable and may be required to pay civil penalties.

Disclosure Overview

Most communications from or about Multnomah County Candidates are required to include a Prominent Disclosure that identifies the true original source(s) of funding for the Communication. The County’s disclosure rules apply to Communications across formats, including audio, video,  print, and electronic.

Some common Communications the disclosure requirements do not apply to include:

  • Communications that are funded with a total of $345 or less
  • Bumper stickers
  • Signs smaller than six square feet
  • Small items worn or carried by individuals, such as buttons or stickers
  • 500 or fewer substantially similar flyers or other pieces of literature distributed in any 10-business day period

Individuals (including Candidates), as well as Entities such as Political Committees, corporations, unions, and nonprofits, that fund Communications in support of or opposition to Candidates for County positions are all subject to the County’s disclosure requirements. 

A Communication that is subject to disclosure requirements must include the names of Individuals or Entities, including Candidate Committees, that paid for the Communication. There are additional disclosure requirements for most Entities in order to provide transparency about their sources of income to the public.

Expenditure Limits

When Multnomah County voters amended the Charter in 2016, they also approved limits for Expenditures, including Independent Expenditures. However, the Expenditure limits were ruled unconstitutional by the state supreme court, which means that those sections of the Charter are not enforceable. The County does not regulate any Expenditures in Multnomah County Candidate elections.
