North Carolina General Statutes Chapter 160A. Cities and Towns § 160A-200.1. Annual notice to chronic violators of public nuisance or overgrown vegetation ordinance

(a) A city may notify a chronic violator of the city's public nuisance ordinance that, if the violator's property is found to be in violation of the ordinance, the city shall, without further notice in the calendar year in which notice is given, take action to remedy the violation, and the expense of the action shall become a lien upon the property and shall be collected as unpaid taxes.

(b) The notice shall be sent by registered or certified mail. When service is attempted by registered or certified mail, a copy of the notice may also be sent by regular mail. Service shall be deemed sufficient if the registered or certified mail is unclaimed or refused, but the regular mail is not returned by the post office within 10 days after the mailing. If service by regular mail is used, a copy of the notice shall be posted in a conspicuous place on the premises affected.

(c) A city may also give notice to a chronic violator of the city's overgrown vegetation ordinance in accordance with this section.

(d) For purposes of this section, a chronic violator is a person who owns property whereupon, in the previous calendar year, the city gave notice of violation at least three times under any provision of the public nuisance ordinance.
