Michigan Compiled Laws, Chapter 207. Taxation § 207.957

Sec. 7. (1) A qualified residential facility for which a certificate is in effect, but not the land on which the qualified residential facility is located, for the period on and after the effective date of the certificate and continuing so long as the certificate is in force, is exempt from ad valorem property taxes collected under the general property tax act, 1893 PA 206, MCL 211.1 to 211.155.

(2) Unless earlier revoked as provided in section 12,  1 a certificate shall remain in force and effect for a period to be determined by the legislative body of the qualified local governmental unit. The beginning date for the period that the certificate is in force and effect may be delayed for a period of up to 5 years from the date of approval of the application as determined by the legislative body of the qualified local governmental unit. The certificate may be issued for a period of at least 1 year, but not to exceed 12 years. If the number of years determined is less than 12, the certificate may be subject to review by the legislative body of the qualified local governmental unit and the certificate may be extended. The total amount of time determined for the certificate including any extensions shall not exceed 12 years after the completion of the qualified residential facility. The certificate shall commence with its effective date and end on the December 30 immediately following the last day of the number of years determined. The date of issuance of a certificate of occupancy, if required by appropriate authority, shall be the date of completion of the qualified residential facility.

(3) If the number of years determined by the legislative body of the qualified local governmental unit for the period a certificate remains in force is less than 12 years, the review of the certificate for the purpose of determining an extension shall be based upon factors, criteria, and objectives that shall be placed in writing, determined and approved at the time the certificate is approved by resolution of the legislative body of the qualified local governmental unit and sent, by certified mail, to the applicant, the assessor of the local tax collecting unit in which the qualified residential facility is located, and the commission.
