The right may be lost through abandonment, discontinuance for the statutory period, or amortization ordinances that require termination after a reasonable period.

Neville Norton has operated a gas station on his property for twenty-five years. The city recently rezoned the area for residential use only and ordered all nonconforming businesses to close within thirty days. Norton sues to block enforcement. The court upholds his right to continue the station because the use predated the zoning change and the city provided no amortization period or other recognized basis for immediate termination.
Natasha Nielsen owns an auto repair shop that became nonconforming after rezoning to residential. The ordinance allows her to continue operations for seven years before the use must end. Nielsen challenges the phase-out as unreasonable given her investment. The court sustains the ordinance because the period accounts for the nature of the business and permits recovery of capital before cessation.
Norman Nash operates an adult bookstore that was lawful when opened. After the borough enacts a zoning rule barring such uses in the commercial district, Nash claims the restriction eliminates his vested right. The court examines whether the ordinance leaves reasonable alternative locations and whether the burden on the preexisting use is justified by the public interest in land-use planning.
Nina Nielsen owns commercial property operating as a nonconforming use after rezoning. The city initiates eminent domain proceedings to acquire the parcel for redevelopment. Nielsen argues the taking must account for the value of the vested nonconforming right. The court requires compensation that reflects both the land and the protected continuation of the established use.
Nancy Nelson maintains a structure that became nonconforming under new design standards. The city denies a permit for alterations that would preserve the nonconforming character. Nelson contends the denial effectively terminates the vested use without due process. The court weighs whether the aesthetic regulation bears a substantial relation to public welfare while respecting the preexisting right.
Nikhil Narayan owns a terminal building operating as a nonconforming use after zoning changes. The city designates the structure a landmark and bars alterations needed to continue the prior activity. Narayan claims the restrictions destroy the vested right without compensation. The court assesses whether the landmark rules permit a reasonable economic return on the protected nonconforming use.
A landowner acquires a vested right when the use was lawful when established and the later zoning change renders it nonconforming. The right protects continuation of the specific use against immediate elimination by the municipality.

The right may be lost through voluntary abandonment, discontinuance for the statutory period, or under a valid amortization ordinance that provides a reasonable phase-out period. Involuntary closures, such as those compelled by external orders, do not extinguish the right.

An amortization period is reasonable when it accounts for the nature of the use, the owner's investment, and the time needed to recover capital before the use must cease. Courts evaluate whether the period allows fair adjustment without amounting to a taking.

Internal remodeling that does not expand the building footprint or change the fundamental character of the use does not forfeit protection. The key inquiry is whether the alterations create a materially different use or merely enhance the existing one.

A municipality generally cannot immediately terminate a nonconforming use simply by rezoning. The owner retains a vested right to continue the use absent abandonment, statutory discontinuance, or a reasonable amortization scheme.
