The provisions of the LTRA relate to claims against security deposits, and neither preempt nor shorten the limitations period for common law claims for rent owed or for damages.
Quote Quoting Oak Park Village v Gorton, 128 Mich App 671, 679-680; 341 NW2d 788 (1983).
A statute of limitations must afford a reasonable time within which a suit may be brought. Given the other sections of the LTRA, which provide for a 30-day notice of damages and a 7-day response by the tenant, there would commonly be fewer than eight days within which to commence suit for all damages, even if those damages were in excess of a security deposit. This is an unprecedentially brief time; one so brief as to be deemed unreasonable. Dyke v Richard, 390 Mich 739, 746; 213 NW2d 185 (1973).

We, however, do not deem the 45-day time limit of § 13(1) to be a statute of limitations because no legislative intent to shorten the applicable period of limitations or to abolish the common-law action for damages is expressed in the title of the statute, as required by Const 1963, art 4, § 24. The title of the landlord tenant relationship act states:

"An act to regulate relationships between landlords and tenants relative to rental agreements for rental units; to regulate the payment, repayment, use and investment of security deposits; to provide for commencement and termination inventories of rental units; to provide for termination arrangements relative to rental units; to provide for legal remedies; and to provide penalties." (Emphasis added.)

Nothing in the title suggests that the LTRA is intended to abolish a pre-existing remedy for damages or to shorten an existing statute of limitations....

[W]e hold that § 13(1), in light of the overall statutory scheme of the LTRA, deals strictly with claims for damages to be secured out of security deposits, and does not in any way enhance, restrict, or affect pre-existing statutory and common-law remedies for damages or for unpaid rent.
