NC S587

Adds statutory definition of "nonconformity" to include lots, structures, property uses, dwellings, accessory buildings, signs, parking areas, and other site elements that were lawfully established but no longer comply with current development regulations

Amendments to land development regulations cannot be enforced against nonconformities without written consent of the property owner, establishing vested rights that prevent local governments from changing, impairing, or delaying the existing use

Nonconformity vested rights expire only after intentional and voluntary discontinuance for at least 24 consecutive months, with automatic tolling during pending litigation, board of adjustment proceedings, or emergency declarations

Reconstruction, repair, and maintenance of nonconformities are allowed by right as long as the nonconforming use is not extended, expanded, enlarged, or intensified

Modifies down-zoning restrictions to allow local government-initiated down-zoning without property owner consent, and applies retroactively to nonconformities existing on or after December 11, 2024
