Michigan Rent Increase Notice (No Statutory Period; MCL 123.411, 554.134)

No Michigan statute fixes a specific notice period or cap for raising rent on a private residential tenancy. MCL 123.411 bars local rent control: a local unit "shall not enact, maintain, or enforce an ordinance or resolution that would have the effect of controlling the amount of rent charged for leasing private residential property." Because rent on a fixed-term lease cannot change until the term ends unless the lease allows it, increases in practice arise on month-to-month tenancies. To impose new terms, the landlord effectively ends the existing month-to-month tenancy, which under MCL 554.134 requires notice equal to the rental interval (one month). A landlord cannot raise rent mid-term in violation of an existing lease.

No specific statutory penalty. A rent increase imposed before a fixed-term lease ends, or without proper month-to-month notice, is unenforceable as a breach of the lease (MCL 123.411; MCL 554.134).
