About the Public Financing Program

The San Francisco Ethics Commission administers a limited public campaign financing program for candidates running for Mayor or Supervisor. Under the program, candidates for the Office of Mayor who qualify and meet program eligibility requirements may receive up to $1,200,000 in public funds ($1,185,500 for incumbent candidates).  Candidates for the Board of Supervisors may receive up to $255,000 in public funds ($252,000 for incumbent candidates). 

The public campaign financing program serves many important public policy goals. The program seeks to ensure that candidates with a demonstrated level of community support can secure sufficient resources to mount a viable campaign. In doing so, public financing reduces candidates’ dependence on large private contributions, which lessens the potential for and appearance of undue influence by contributors and serves to improve the public’s trust in local government. Public financing also seeks to enable candidates to spend less time fundraising and more time interacting with voters and engaging in discussions on important issues. The availability of public funds also encourages citizens to be more politically active by incentivizing and empowering small-dollar contributions. By supporting candidates who have community support, public financing can also lead to more competitive races, which is important in ensuring quality representation of constituents.

Eligibility

To participate in the public financing program, interested candidates must first meet all qualification requirements of the Department of Elections to appear on the ballot. Candidates who qualify to appear on the ballot must also meet the following program eligibility requirements:

• Raise a minimum number and total dollar amount of contributions from San Francisco residents: A non-incumbent Supervisorial candidate is required to raise qualifying contributions totaling at least $10,000 from at least 100 contributors, while an incumbent Supervisorial candidate is required to raise qualifying contributions totaling at least $15,000 from at least 150 contributors. A non-incumbent Mayoral candidate is required to raise qualifying contributions totaling at least $50,000 from at least 500 contributors, while an incumbent Mayoral candidate is required to raise qualifying contributions totaling at least $75,000 from at least 750 contributors. Only contributions between $10 and $100 count as qualifying contributions. These qualifying contributions must be received by the candidate no earlier than 18 months before the date of the election and no later than the 70^th day before the election.
• Be opposed by a candidate who receives contributions or makes expenditures over a minimum amount: Supervisorial candidates must be opposed by a candidate who raises or spends at least $10,000. Mayoral candidates must be opposed by a candidate who raises or spends at least $50,000.
• Adhere to campaign spending limits: Candidates must adhere to campaign spending limits (Individual Expenditure Ceiling, or “IEC”) which may be adjusted. The initial IEC for Supervisorial candidates is $350,000.  The initial IEC for Mayoral candidates is $1.7 million. Based on financial activity in a candidate’s race, the candidate’s spending limit (or Individual Expenditure Ceiling, “IEC”) shall be raised by the Ethics Commission. This provision intends for candidates who are bound by a spending limit to have the ability to respond when independent expenditures and opponent fundraising exceed the candidate’s initial IEC. Three factors are assessed to determine if an increase to a candidate’s IEC is warranted: (1) contributions received by the candidate’s opponents, (2) independent expenditures in support of the candidate’s opponents, and (3) independent expenditures in opposition of the candidate. A Supervisorial candidate’s IEC is adjusted in increments of $50,000, and a Mayoral candidate’s IEC is adjusted in increments of $250,000. Spending limits are regularly reviewed by Commission staff and adjusted on a candidate-by-candidate basis. It is therefore possible for candidates in the same race to have different IEC limits or to have their IEC adjusted at different times/intervals.

In addition to the requirements above, candidates must not accept loans from others, abide by limits on the amount of funds they loan/donate to their own campaign, agree to debate their opponents, and are subject to mandatory audit. Candidates, committee treasurers, and committee officers participating in the public financing program are responsible for understanding and complying with all eligibility requirements.

Candidate Disbursements

Once certified as eligible for the program, candidates receive an initial grant. Supervisorial candidates receive an initial grant of $60,000. Mayoral candidates receive an initial grant of $300,000. After receiving the initial grant, candidates may receive matching funds distributed at a six-to-one ratio for every dollar of contributions received up to $150 from any single contributor. Non-incumbent Supervisorial candidates can have up to $32,500 in private contributions matched (for a maximum of $255,000 of public financing), while incumbent Supervisorial candidates can have up to $32,000 in contributions matched (for a maximum of $252,000 of public financing). Non-incumbent Mayoral candidates can have up to $150,000 in private contributions matched (for a maximum of $1,200,000 of public financing), while incumbent Mayoral candidates can have up to $147,500 in contributions matched (for a maximum of $1,185,000 of public financing). The tables below summarize the potential disbursements.
