What does "amortization" refer to in zoning practice?

In zoning practice, amortization typically refers to the process of determining the remaining useful life of a pre-existing non-conforming use. This means that when a land use does not conform to current zoning regulations, a jurisdiction may allow that use to continue for a period of time, which is determined based on factors such as the nature of the use, its investment, and its contribution to the community. During this amortization period, the property owner is generally expected to phase out the non-conforming use as the time limit expires, allowing the land to eventually transition to a use that complies with current zoning laws. This approach balances the interests of property owners with the need to enforce zoning regulations that reflect community priorities and planning goals.
