Land Use & Zoning

In Minnesota, a municipality's zoning ordinance cannot be applied retroactively to a use that was legally established before the ordinance was enacted. This principle protects:

AOnly agricultural uses
BNonconforming uses that were legal when established (grandfathered uses)✓ Correct
CAny commercial use regardless of when established
DOnly religious uses

Explanation

The principle of nonconforming use (grandfathered use) protects lawful uses that were established before a zoning ordinance was enacted or changed. The owner may continue the use (though not expand it), and the use cannot be retroactively prohibited. This is a fundamental protection under Minnesota and constitutional law.
