Michigan Compiled Laws, Chapter 125. Planning, Housing and Zoning § 125.3507

Sec. 507.  (1) As used in this section and sections 508 and 509,  1 “PDR program” means a purchase of development rights program.

(2) The legislative body may adopt a development rights ordinance limited to the establishment, financing, and administration of a PDR program, as provided under this section and sections 508 and 509.  The PDR program may be used only to protect agricultural land and other eligible land.  This section and sections 508 and 509 do not expand the condemnation authority of a local unit of government as otherwise provided for in this act.

(3) A PDR program shall not acquire development rights by condemnation.  This section and sections 508 and 509 do not limit any authority that may otherwise be provided by law for a local unit of government to protect natural resources, preserve open space, provide for historic preservation, or accomplish similar purposes.

(4) A legislative body shall not establish, finance, or administer a PDR program unless the legislative body adopts a development rights ordinance.  If the local unit of government has a zoning ordinance, the development rights ordinance may be adopted as part of the zoning ordinance under the procedures for a zoning ordinance under this act.  A local unit of government may adopt a development rights ordinance in the same manner as required for a zoning ordinance.

(5) A legislative body may promote and enter into agreements with other local units of government for the purchase of development rights, including cross-jurisdictional purchases, subject to applicable development rights ordinances.
