The Planning Division and Code Enforcement administer location, size, duration, and placement rules for temporary signs. Specific fee amounts, fine schedules, and form numbers are not specified on the cited pages listed in Resources below; consult those official pages for updates.

Always check with Planning or Code Enforcement before posting signs near public rights-of-way.

  • Temporary political signs are typically allowed on private property with the owner’s permission and may be subject to size and duration limits.
  • There are usually time limits tied to election periods (e.g., a limited number of days before and after election day) but exact timeframes are not specified on the cited pages.
  • Restrictions often prohibit signs that create hazards, use reflective materials that distract drivers, or are attached to public fixtures like streetlights or power poles.
