Michigan Compiled Laws, Chapter 460. Public Utilities § 460.730

Sec. 10. This act does not authorize, affect, or impair local ordinances, charters, or other provisions of law requiring permits to be obtained before excavating or tunneling in a public street or highway or to construct or demolish buildings or other structures on private property. A permit issued by a governmental agency does not relieve a person from the responsibility of complying with this act. The failure of any person who has been granted a permit to comply with this act does not impose any liability upon the governmental agency issuing the permit.
