(1) A person filing a declaration of candidacy for an office shall, at the time of filing, be a registered voter and possess the qualifications specified by law for persons who may be elected to the office.

(2) Excluding the office of precinct committee officer or a temporary elected position such as a charter review board member or freeholder, no person may file for more than one office.

(3) The name of a candidate for an office shall not appear on a ballot for that office unless, except for judge of the superior court and as provided in RCW 3.50.057, the candidate is, at the time the candidate's declaration of candidacy is filed, properly registered to vote in the geographic area represented by the office. For the purposes of this section, each geographic area in which registered voters may cast ballots for an office is represented by that office. If a person elected to an office must be nominated from a district or similar division of the geographic area represented by the office, the name of a candidate for the office shall not appear on a primary ballot for that office unless the candidate is, at the time the candidate's declaration of candidacy is filed, properly registered to vote in that district or division. The officer with whom declarations of candidacy must be filed under this title shall review each such declaration filed regarding compliance with this subsection.

(4) The requirements of voter registration and residence within the geographic area of a district do not apply to candidates for congressional office. Qualifications for the United States congress are specified in the United States Constitution.
