North Carolina General Statutes Chapter 163. Elections and Election Laws § 163-296. Nomination by petition

In cities conducting partisan elections, any qualified voter who seeks to have his name printed on the regular municipal election ballot as an unaffiliated candidate may do so in the manner provided in G.S. 163-122, except that the petitions and affidavits shall be filed not later than 12:00 noon on the Friday preceding the seventh Saturday before the election, and the petitions shall be signed by a number of qualified voters of the municipality equal to at least one and a half percent (1.5%) of the whole number of voters qualified to vote in the municipal election according to the voter registration records of the State Board of Elections as of January 1 of the year in which the general municipal election is held. A person whose name appeared on the ballot in a primary election is not eligible to have his name placed on the regular municipal election ballot as an unaffiliated candidate for the same office in that year. The Board of Elections shall examine and verify the signatures on the petition, and shall certify only the names of signers who are found to be qualified registered voters in the municipality. Provided that in the case where a qualified voter seeks to have his name printed on the regular municipal election ballot as an unaffiliated candidate for election from an election district within the municipality, the petition shall be signed by one and a half percent (1.5%) of the voters qualified to vote for that office.
