N.C. Gen. Stat. § 160A-237
The assessment resolution may provide that assessments levied under this Article for water or sewer improvements be held in abeyance without interest until improvements on the assessed property are actually connected to the water or sewer system for which the assessment was levied, or a date certain not more than 10 years from the date of confirmation of the assessment roll, whichever event first occurs. Upon termination of the period of abeyance, the assessment shall be paid in accordance with the terms set out in the assessment resolution. If assessments are to be held in abeyance, the assessment resolution shall classify the property assessed according to general land use, location with respect to the water or sewer system, or other relevant factors, and shall provide that the period of abeyance shall be the same for all assessed property in the same class.
All statutes of limitations are suspended during the time that any assessment is held in abeyance without interest.
