Michigan’s Landlord-Tenant Relationship Act, codified at MCL 554.601–554.616, is the state law that governs residential security deposits and the mechanics of the landlord-tenant relationship after a lease is signed. It caps deposits at one and a half months’ rent, requires specific written notices at move-in, gives landlords hard deadlines to return the deposit or sue for damages, and lets tenants recover double any amount wrongfully withheld. A companion statute, the Truth in Renting Act (MCL 554.631–554.641), controls what a lease itself can and cannot say.
What the Act Covers
The Act is narrower than people often assume. It is primarily about money held on behalf of a tenant — how much a landlord can collect, where it has to sit, what notices have to accompany it, and what the timeline looks like when the tenant moves out. It works alongside other Michigan laws that handle related pieces of renting: the Truth in Renting Act for lease terms, the summary-proceedings statute (MCL 600.5714 and following) for evictions, and the Housing Law of Michigan for habitability standards. If you are searching for your rights around the deposit and the paperwork surrounding it, this is the statute doing the work.
Security Deposit Limit
A Michigan landlord cannot collect more than one and a half months’ rent as a security deposit.1Michigan Legislature. MCL – Section 554.602 – Security Deposit Amount On a $1,200 monthly rent, the ceiling is $1,800. The deposit must be held in a regulated financial institution and cannot be mixed with the landlord’s personal or operating funds.
Move-In Notice and Inventory Checklist
Within 14 days after a tenant moves in, the landlord must deliver written notice containing three things: the landlord’s name and address, the name and address of the financial institution holding the deposit, and a statement telling the tenant they must provide a forwarding address within four days after moving out. The forwarding-address statement has to appear in 12-point boldface type. If the landlord skips this written notice, the tenant is no longer obligated to provide a forwarding address at all.2Michigan Legislature. MCL – Section 554.603 – Security Deposit Notice
The landlord must also provide an inventory checklist showing the condition of the unit at move-in. The tenant has seven days to review it and dispute anything they disagree with. That checklist becomes the baseline when the landlord assesses damage after move-out, so a tenant who ignores it or lets the seven days lapse loses the strongest piece of evidence for arguing later that a scuff or stain was already there.
Getting Your Deposit Back
Two deadlines run against the landlord after a tenant moves out, and both matter.
First deadline: within 30 days after the tenant leaves, the landlord must either return the full deposit or send an itemized list of claimed damages along with whatever balance remains.3Michigan Legislature. MCL – Section 554.609 – Itemized List of Damages Legitimate deductions include unpaid rent and damage beyond normal wear and tear. Faded paint and minor carpet wear from ordinary use are not deductible.
Second deadline: if the tenant disputes the deductions in writing and the dispute is not resolved, the landlord has 45 days from move-out to file a lawsuit for the disputed amount. Miss that 45-day window and the landlord forfeits all claimed damages and becomes liable to the tenant for double the amount wrongfully retained.4Michigan Legislature. MCL – Section 554.613 – Security Deposit Remedies That double-damages penalty is the sharpest enforcement tool tenants have under the Act.
The tenant’s own step is short but important: send the forwarding address in writing within four days of moving out. That is what starts the landlord’s 30-day clock in a form the tenant can later prove.
What the Lease Itself Has to Say
The Truth in Renting Act sits next to the Landlord-Tenant Relationship Act and polices lease content. Any written lease must include the landlord’s name and an address where notices can be sent, and it must carry a prominent statement in at least 12-point type telling the tenant that Michigan law establishes rights and obligations for rental agreements and that the tenant may want to consult a lawyer or other qualified person about anything they don’t understand.5Michigan Legislature. MCL – Section 554.634 – Truth in Renting Act, Rental Agreement Mandatory Statements
Certain lease clauses are automatically void, no matter what the tenant signed. Provisions that try to waive tenant rights, allow eviction without legal process, or impose unreasonable penalties cannot be enforced.6Michigan Legislature. MCL – Section 554.631 – Truth in Renting Act A late fee is allowed but should reflect the landlord’s actual cost of dealing with a late payment; a court can throw out a fee it considers an excessive penalty.
One thing to note: Michigan does not require a written lease for rental agreements shorter than one year. Verbal agreements are enforceable in principle, but they leave both sides exposed when a dispute arises over what was actually promised.
Rent Changes During a Lease
Michigan has no statewide rent control, so a landlord can set the starting rent at whatever the market allows. Once a lease is signed, though, the landlord generally cannot change rent or other terms without the tenant’s written consent.
There is a narrow exception. If the lease contains a clause allowing adjustments, the landlord can make certain changes with 30 days’ written notice, limited to adjustments required by law, rules protecting health and safety, and rent increases tied to documented rises in property taxes, utility costs, or insurance premiums. The increase has to correspond to a real cost increase in one of those categories.
For month-to-month tenancies, either side can end the arrangement with one full rental cycle of notice — one month’s notice from a tenant paying monthly, and the same from the landlord before raising rent or terminating.
Evictions Have to Go Through Court
A Michigan landlord cannot change the locks, shut off utilities, or physically remove a tenant. Every eviction runs through the summary-proceedings process, which begins with the right written notice and ends with a court order carried out by a court officer or law enforcement.
The notice period depends on the reason:
- Nonpayment of rent: 7-day written demand for possession. The tenant has seven days to pay in full or leave.7Michigan Legislature. MCL – Section 600.5714 – Summary Proceedings to Recover Possession
- Health hazard or extensive property damage: 7-day demand for possession or for the tenant to substantially restore the premises.
- Drug activity on the premises, when the lease has a controlled-substance termination clause and a police report has been filed: 24-hour demand for possession.
- Holdover after a lease ends or a month-to-month tenancy is terminated: the landlord serves the notice to quit under MCL 554.134 before filing in court.
If the tenant does not comply, the landlord files a complaint in district court. The court issues a summons, which in most eviction cases must be issued within 10 days and served at least 3 days before the trial date.8Michigan Legislature. MCL – Section 600.5735 – Summons in Summary Proceedings Both sides present evidence at the hearing. If the court rules for the landlord and the tenant still refuses to leave, the landlord obtains a writ of eviction so a court officer or law enforcement can carry out the removal.
Retaliation Is a Defense
A Michigan court will not grant possession to a landlord if the eviction is primarily motivated by retaliation. Protected tenant activities include enforcing rights under the lease or under federal, state, or local law, filing a complaint with a government agency about health or safety code violations, and participating in a tenant organization.9Michigan Legislature. MCL – Section 600.5720 – Judgment for Possession, Retaliatory Termination
If the tenant took one of those protected actions through a court or government agency within the 90 days before the eviction filing, and that action was not dismissed or denied, a presumption of retaliation arises. The landlord then has to prove the eviction was for a legitimate, non-retaliatory reason. The same protection applies to punitive rent increases or added lease obligations.
How to Enforce Your Rights
A tenant whose landlord missed the 30-day itemization deadline, missed the 45-day lawsuit deadline, or deducted for normal wear and tear can sue for double the amount wrongfully retained.4Michigan Legislature. MCL – Section 554.613 – Security Deposit Remedies Michigan’s small claims court handles disputes up to $7,000, which covers the vast majority of deposit cases without a lawyer.
For habitability problems — heat, plumbing, electrical, structural issues — tenants can deposit rent into an escrow account through the court instead of paying the landlord directly, seek code enforcement from local housing authorities, or file a complaint with the Michigan Attorney General’s office. A court can order the landlord to make repairs or reduce rent to reflect the diminished condition of the property. Withholding rent informally, or paying for repairs and subtracting the cost from rent, carries real legal risk in Michigan; the statutory route is rent escrow through the court.
Landlords have their own remedies. If the deposit does not cover legitimate damage, the landlord can file a separate civil lawsuit for unpaid rent, repair costs, and legal fees after following the itemization and 45-day suit process the Act requires.
