Often a one-page mailer combines the display rules with both the committee name and address in no less than 14-point, bold sans serif type font although the address may be at 6 pt. type.

The guidance above incorporates requirements imposed pursuant to state and San Francisco law.  The information on this chart does not carry the force of law. If there are any discrepancies between the chart and state or local law or their corresponding regulations and opinions, the law, regulations and opinions will control.

Note that compliance with the disclaimer rules for ballot measure ads will satisfy electioneering communications disclaimer requirements, which may be triggered if the ad mentions a City candidate.
