Mich. Comp. Laws § § 554.640
Exception.
Operative Text
Sec. 10. This act shall not apply to a rental agreement entered into before the effective date of this act.
Section 554.640 of Michigan's Truth in Renting Act establishes a temporal boundary for the law's reach: rental agreements that were fully executed before the Act's effective date are not subject to its requirements. The law operates prospectively, meaning only agreements entered into on or after that date fall within its scope. This carve-out preserves the terms and enforceability of pre-existing rental contracts under the rules that applied when those agreements were made.
Plain English — not legal advice.
Under MCL § 554.640, property owners and managers whose rental agreements predate the effective date of the Truth in Renting Act are not required to bring those legacy agreements into compliance with the Act's provisions. Compliant operators generally track the execution dates of their leases to determine which statutory requirements apply to each agreement. When renewing or replacing a pre-Act lease with a new agreement, operators typically treat the new document as subject to the Act's full requirements.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
MCL § 554.640 means that if your rental agreement was signed before the Truth in Renting Act took effect, the Act's protections and requirements do not automatically apply to that contract. Tenants in this situation may want to review what rules governed their agreement at the time it was signed, and can consult a tenant-rights organization for general information about which protections may still be available under other Michigan law. If a dispute arises over whether the Act applies to a particular agreement, the execution date of the lease is a key factual question that may be worth documenting carefully.
