Minn. Stat. § 117.184: COMPENSATION FOR REMOVAL OF LEGAL NONCONFORMING USE.

(a) Notwithstanding any law to the contrary, an ordinance or regulation of a political subdivision of the state or local zoning authority that requires the removal of a legal nonconforming use as a condition or prerequisite for the issuance of a permit, license, or other approval for any use, structure, development, or activity constitutes a taking and is prohibited without the payment of just compensation. This section does not apply if the permit, license, or other approval is requested for the construction of a building or structure that cannot be built without physically moving the nonconforming use.

(b) This section applies to an action of a political subdivision of the state or a local zoning authority occurring on or after May 20, 2006, that requires removal of a legal nonconforming use as a condition or prerequisite for the issuance of a permit, license, or other approval.
