Pre-existing limitations on land ownership derived from a state's property and nuisance law that inhere in title at the time of acquisition. These limitations permit a regulation eliminating all economically beneficial use without triggering a per se taking under the Fifth Amendment.
Metro Tech bought coastal bluff land to build a data center. After purchase, the state banned all structures in an erosion zone. The ban prevented any buildings, but it duplicated longstanding nuisance rules against development that would accelerate erosion harming neighbors. Because the restriction already inhered in title under those background principles, no compensation was required.
A corporation owned wetlands subject to new state restrictions when Palazzolo became sole shareholder by operation of law. He claimed a total taking. The Court held that post-acquisition notice of the rules did not automatically bar the claim, but any background principles of state property law existing at original acquisition could still defeat compensation.

Owners held lakefront parcels subject to a six-year moratorium on all building. They argued the delay eliminated all economic use. The Court noted that traditional short-term moratoria do not trigger per se liability and that background principles of property law may prevent even longer pauses from qualifying as total takings.
A developer acquired tidal wetlands already subject to common-law nuisance rules against filling that would flood neighboring parcels. After a state permit denial eliminated all economic use, the court held the restriction was a background principle inhering in title, so no compensation was owed.
Chevron challenged a Hawaii rent-control statute limiting gasoline dealers' returns. The Court clarified that background principles of property law determine whether a regulation effects a taking, separate from any inquiry into the government's purpose or the owner's expectations.
An owner acquired shoreline parcels already encumbered by the state's public-trust doctrine reserving the wet-sand area for public use. A later regulation enforcing that line eliminated all development. Because the doctrine was a background principle at acquisition, no total-taking compensation was required.
A total deprivation does not require compensation if the prohibited use was already barred by background principles of state nuisance or property law that existed when the owner acquired title. These principles are treated as inherent limitations already present in the owner's bundle of rights.
No. A later purchaser may still challenge a regulation, but any background principles already in force at the time of the original acquisition remain available to the state as a defense. Notice of existing rules does not itself create new background principles.
Traditional short-term moratoria generally do not eliminate all economic use and therefore fall outside Lucas. Even longer pauses may be shielded if they reflect longstanding implied limitations already part of state property law.
Examples include adverse possession, easements, riparian rights, navigational servitudes, public trust doctrines, and common-law nuisance rules that predate acquisition. These limitations are viewed as already embedded in title rather than newly imposed by regulation.
…rendered petitioner's lots valueless must be accepted, and the South Carolina Supreme Court must determine on remand whether any background principles of state property or nuisance law would have prohibited the uses petitioner now intends. Pp. 1014-1032. (a) Early in this Court's takings jurisprudence, it was determined that government…
