Security deposits are one of the most common parts of renting out a property and one of the areas where a seemingly small procedural mistake can create significant problems for a landlord.

Michigan has specific rules governing how much landlords can collect, what counts as a security deposit, where the money can be held, what information tenants must receive, and what documentation should be completed at move-in. There are also strict deadlines that come into play when the tenancy eventually ends.

For self-managing landlords, understanding these requirements before collecting a deposit is an important part of protecting both your rental property and yourself.

Here’s what Michigan landlords should know about managing a security deposit from the beginning of a tenancy through move-out.

How Much Can a Landlord Charge for a Security Deposit in Michigan?

Michigan law limits a residential security deposit to 1.5 times the monthly rent.

For example:

$1,200 monthly rent = maximum $1,800 security deposit
$1,500 monthly rent = maximum $2,250 security deposit
$2,000 monthly rent = maximum $3,000 security deposit

The 1.5-month limit sounds straightforward, but there’s an important distinction landlords need to understand: what you call a charge doesn’t necessarily determine whether it’s legally considered part of the security deposit.

Security Deposits vs. Fees: What’s the Difference?

Generally, the important question is whether the money is refundable.

If you collect money from a tenant with the expectation that some or all of it will be returned at the end of the tenancy, that money may be considered part of the security deposit, even if you’ve given it another name.

For example, suppose a landlord charges a $500 “pet deposit” that will be returned as long as the pet doesn’t cause damage. Because that money is refundable, it generally counts toward the security deposit and therefore toward Michigan’s 1.5-month maximum.

A genuinely nonrefundable pet fee, by comparison, is a fee rather than a security deposit.

This distinction can apply to other charges as well. Before adding a “deposit” to your move-in costs, consider whether it is refundable and whether collecting it could cause the total security deposit to exceed Michigan’s limit.

Where Can You Keep a Michigan Security Deposit?

Once collected, a security deposit isn’t simply additional income that you can utilize how you see fit.

Under Michigan law, the security deposit remains the tenant’s property until the landlord establishes a right to some or all of it, which occurs after the tenant moves out.

Generally, landlords have two options for handling the funds.

The deposit can be held in a regulated financial institution, such as a bank or credit union. Michigan also provides an alternative process under which a landlord can use security deposit funds after posting the required cash or surety bond.

For many individual landlords, maintaining the deposit separately through an appropriate financial institution is the more straightforward approach.

Whatever method you use, security deposits should be accounted for carefully. Mixing security deposit funds into everyday rental income without understanding Michigan’s requirements can create unnecessary risk. To help maintain clear separation and avoid confusion later, think of the security deposit as funds you are holding onto rather than income.

The First 14 Days Matter

Security deposit compliance doesn’t begin when your tenant moves out. Some of the most important requirements occur immediately after they move in.

No later than 14 days after the tenant assumes possession, a landlord collecting a security deposit must provide written information that includes:

The landlord’s name and address for receiving communications
The name and address of the financial institution where the security deposit is held, or information regarding the applicable surety
Notice of the tenant’s obligation to provide a forwarding mailing address in writing within four days after terminating occupancy

Michigan law specifies particular wording and formatting for the forwarding-address notice. According to MCL 554.603, the landlord must include the following statement in the lease agreement in 12-point bold font that is at least 4 points larger than the body of the lease agreement:

“You must notify your landlord in writing within 4 days after you move of a forwarding address where you can be reached and where you will receive mail; otherwise your landlord shall be relieved of sending you an itemized list of damages and the penalties adherent to that failure.”

This is an important detail because if the landlord doesn’t properly provide the required notice at the beginning of the tenancy, the landlord may not later be able to hold the tenant to the four-day forwarding address requirement.

In other words, something missed during move-in can affect the landlord’s rights at move-out months or years later.

Don’t Overlook the Move-In Inventory Checklist

The inventory checklist is another important part of Michigan’s security deposit process.

When a tenant moves in, a landlord collecting a security deposit must provide two blank copies of an inventory checklist.

The checklist should allow the tenant to document the condition of the rental property and its contents at the beginning of the tenancy.

The checklist also requires specific statutory language notifying the tenant about the seven-day deadline to submit the completed inventory checklist within 7 days and their right to request a copy of the previous tenant’s termination inventory checklist.

Similar to the forwarding address statement requirement on the lease agreement, MCL 554.608 also requires that the following statement be posted at the top of the first page of the checklist in 12-point bold font:

“You should complete this checklist, noting the condition of the rental property, and return it to the landlord within 7 days after obtaining possession of the rental unit. You are also entitled to request and receive a copy of the last termination inventory checklist which shows what claims were chargeable to the last prior tenants.”

While this may sound like paperwork for paperwork’s sake, the inventory checklist can become extremely important later. Not only is this a required part of the process, but documentation is also helpful when determining tenant-responsible damage charges later.

Go Beyond the Minimum Documentation

The inventory checklist establishes an important written record, but we recommend that landlords document property condition beyond the checklist alone.

A strong rental file may include:

Detailed move-in photographs
Video documentation
The completed inventory checklist
Maintenance requests throughout the tenancy
Records of completed repairs
Written tenant communications
Invoices and receipts
Documentation of approved alterations or changes to the property

When taking photos, be sure to capture the room as a whole, and then specific areas up close, including flooring, appliances, countertops, and other included amenities. When tenants move out, be sure to capture close-up photos of the damaged areas so they can be clearly seen.

Keep these records together and make sure photos can be tied to a particular property and date.

What Can a Security Deposit Eventually Be Used For?

Michigan restricts what landlords can claim against a tenant’s security deposit.

Generally, a security deposit may be applied toward qualifying obligations such as unpaid rent, certain unpaid utilities for which the tenant is responsible, and actual damage to the rental property beyond reasonable wear and tear.

This is where the distinction between damage and normal deterioration from living in a home becomes particularly important.

Not every item that needs attention after a tenant moves out is automatically a tenant charge.

That topic can become much more complicated once depreciation, documentation, repair costs, and tenant disputes are involved, which is why we’ve covered the move-out and Notice of Damages process separately in our guide, Security Deposits and Notice of Damages: What Michigan Property Owners Need to Know.

Know the Security Deposit Timeline

One of the easiest ways for a self-managing landlord to get into trouble is simply missing a deadline. With security deposits, knowing what to do is only half the battle, while knowing when to do it is the remaining half.

Here’s a helpful overview of the major milestones in Michigan’s security deposit process:

At Move-In: Collect no more than 1.5 times the monthly rent as the security deposit and properly handle the funds. Provide the tenant with two copies of the inventory checklist.
Within 7 Days of Possession: The tenant generally completes and returns the move-in inventory checklist.
Within 14 Days of Possession: Provide the required security deposit information and statutory forwarding-address notice.
Throughout the Tenancy: Maintain records of property condition, repairs, tenant communications, and other information that could become relevant at move-out.
Within 4 Days After Move-Out: The tenant is generally responsible for providing a forwarding mailing address in writing, assuming the landlord properly provided the required notice.
Within 30 Days After Move-Out: The landlord must generally return the security deposit or mail the tenant an itemized Notice of Damages and the remaining balance, if applicable.
Within 7 Days After Receiving the Notice: The tenant has an opportunity to dispute the landlord’s claims.
Within 45 Days After Move-Out: If qualifying charges remain disputed, the landlord may need to file a court action to retain the disputed security deposit funds, unless a statutory exception applies.

The last three steps are where the Notice of Damages process becomes especially important. Our separate Notice of Damages guide takes a deeper look at those requirements, including tenant disputes, depreciation, settlements, and when court involvement may become necessary.

Michigan’s Security Deposit Rules Can’t Simply Be Waived

Another important point for self-managing landlords: you generally can’t solve a security deposit compliance issue by putting different terms in your lease. Michigan’s statutory security deposit requirements cannot simply be waived by agreement between the landlord and tenant.

For example, having a tenant agree to a security deposit greater than the statutory maximum doesn’t necessarily make that deposit permissible.

Your lease is an important tool, but its terms still need to comply with applicable Michigan law.

Build a Process Before You Need One

Security deposit problems often don’t begin at move-out.

They begin much earlier:

A required notice wasn’t provided.
The inventory checklist wasn’t completed.
Move-in photos can’t be located.
A repair occurred two years ago, but nobody documented why.
A refundable fee caused the total deposit to exceed the statutory limit.

The tenant moves out, a disagreement occurs, and suddenly those seemingly minor administrative details matter.

The best way to avoid this is to establish a repeatable process before the tenancy begins.

Create standard procedures for collecting and holding deposits, delivering required notices, documenting move-in condition, retaining records, tracking tenant communications, completing move-out inspections, and monitoring deadlines.

Consistency can be one of a landlord’s best forms of risk management.

Property Management Is More Than Collecting Rent

Security deposits are a good example of why professional property management involves much more than finding a tenant and collecting monthly rent.

Managing a rental property means maintaining processes throughout the entire tenancy, from lease preparation and move-in documentation to maintenance records, compliance requirements, renewals, inspections, and eventually move-out.

At United Properties of West Michigan, we’ve built systems around those responsibilities so property owners don’t have to create and manage every process themselves.

For a self-managing landlord, the question isn’t necessarily whether you can handle these responsibilities. Many owners can.

The better question may be whether managing the details, deadlines, documentation, tenant communication, maintenance, and compliance requirements is the best use of your time.

In fact, many self-managing landlords partner with a property management company at some point for the reasons listed here. It’s less about your abilities and more about weighing if the time and effort are beginning to outweigh the benefits.
