MI SB1091

Amends the Recodified Tax Increment Financing Act to require municipalities to preserve public facilities, buildings, or structures with significant historical interests and equip historic sites with fire alarm systems at minimum.

Requires authorities to refer all proposed permanent exterior changes to historic sites (listed on state or national registers) to the local historic district commission established under the Local Historic Districts Act, 1970 PA 169, which must follow U.S. Secretary of the Interior's standards for rehabilitation.

For historic sites not located in a local historic district, requires authorities to refer proposed changes to the state historic preservation office at least 30 days prior to making permanent exterior changes through December 31, 2023.

Establishes civil penalties of up to $30,000 for authorities that violate referral requirements by demolishing historic facilities; collected fines fund a grant program for nonprofit historic preservation organizations and local governments, with 5% retained for administrative costs.

Takes effect January 1, 2019.
