MI HB6174

Amends the Neighborhood Enterprise Zone Act to modify definitions of "condominium unit," "new facility," and "rehabilitated facility" to expand eligibility for tax benefits.

Allows condominium units within qualified historic buildings to be held under common ownership and permits individual condominium units to qualify for certificates regardless of whether they are rented, leased, or available for rent for up to 5 years.

Expands "new facility" definition to include rental apartments in mixed-use buildings with street-level retail located in qualified downtown revitalization districts.

Modifies the effective date provision for neighborhood enterprise zone certificates, allowing owners to request that the certificate effective date be December 31 of the year immediately preceding completion or occupancy for new and rehabilitated facilities.

Clarifies documentation requirements for obtaining certificates, including certificates of occupancy, building code compliance documentation, cost requirement proof, and owner affidavits confirming principal residence occupancy.
