These procedures apply to situations in which a person, partnership, or corporation reconstructs, repairs, alters, maintains, establishes, or uses a structure, sign, building, lot, or land use in a manner that violates one or more of the provisions of this chapter. In other words, these procedures apply to situations involving an illegal structure, sign, lot, or use. They do not apply to situations involving a structure, sign, lot, or use that is a nonconformity (as defined in Article I, § 430-17, Nonconformities) or that has a variance (as defined in § 430-27, Variances).
