Michigan Co-Signer Guarantor Agreement

This Co-Signer Guarantor Agreement is built with Michigan as the governing state. These are the Michigan landlord-tenant rules that most often bear on it, with the statute for each.

Security deposits in Michigan

A Michigan security deposit — any refundable money held beyond the first full rental period, whatever it is called — may not exceed one and one-half months’ rent (MCL 554.602). The Act is strict about paperwork and deadlines, and a landlord who misses them loses the right to keep any of the deposit.

  • Where it’s held — The deposit must be kept at a regulated financial institution. A landlord may use the deposited funds only after filing a cash or surety bond with the Secretary of State to secure them (MCL 554.604).
  • 14-day notice — Within 14 days after the tenant moves in, the landlord must give written notice of the landlord’s name and address for receiving communications and the name and address of the bank or surety holding the deposit. It must also warn, in 12-point bold type, that the tenant must give a forwarding address within 4 days of moving out (MCL 554.603).
  • Inventory checklist — The landlord must provide two blank move-in inventory checklists; the tenant has 7 days after moving in to complete one and return it. A move-out checklist follows at the end of the tenancy (MCL 554.608).
  • Return — Within 30 days after the tenant moves out, the landlord must mail an itemized list of damages with the estimated cost of each repair, and return any balance. Missing the 30 days means the landlord agrees no damages are owed and must return the full deposit (MCL 554.609, 554.610).
  • Suing to keep it — If the tenant disputes the list, the landlord must file suit within 45 days of move-out to keep any disputed amount. A landlord who doesn’t follow this procedure waives the claimed damages and owes the tenant double the amount of the deposit retained (MCL 554.613).

Rent, late fees & rent increases

  • Late fees — Michigan has no statutory late-fee cap or mandatory grace period. A fee must be written into the lease and should reasonably reflect the landlord’s cost of late payment — a fee that works as a penalty can be struck by a court.
  • Rent increases — There’s no statewide notice rule for increases. Rent under a fixed-term lease can’t change mid-term unless the lease says so, and a lease can’t let the landlord change terms mid-lease without the tenant’s written consent, apart from narrow exceptions — changes required by law, reasonable health and safety rules, or pass-through of increased taxes, utility or insurance costs if the lease allows it — on at least 30 days’ notice (MCL 554.633). For month-to-month tenancies, an increase needs at least the one-month termination notice.
  • Rent control — Michigan prohibits cities, villages, townships and counties from controlling the rent on private residential property (MCL 123.411).
  • Source of income — Since April 2, 2025, the Elliott-Larsen Civil Rights Act bars landlords with five or more units from discriminating based on source of income — such as a housing voucher or other housing assistance, Social Security, veterans’ benefits, public assistance, child support or alimony.

Required notices in a Michigan lease

  • Truth in Renting notice — Every lease must state prominently: “NOTICE: Michigan law establishes rights and obligations for parties to rental agreements. This agreement is required to comply with the Truth in Renting Act…” and give the landlord’s address for notices (MCL 554.634).
  • Domestic violence notice — The lease should state that a tenant with a reasonable apprehension of present danger to the tenant or the tenant’s child from domestic violence, sexual assault or stalking may have special statutory rights to seek a release of rental obligation under MCL 554.601b. If it doesn’t, the landlord must post or hand over that notice at signing (MCL 554.601b).
  • Senior early-termination right — The 60-day release for tenants of 13+ months entering senior housing or unable to live independently (MCL 554.601a).
  • Deposit notices — The 14-day deposit-holder notice with the bolded forwarding-address warning, and the move-in inventory checklists (MCL 554.603, 554.608).
  • Lead-based paint — Federal lead warning and known-hazard disclosure for housing built before 1978 (42 U.S.C. §4852d).

Michigan Co-Signer Guarantor Agreement FAQs

How much can a landlord charge for a security deposit in Michigan?

No more than one and one-half months’ rent. Any refundable amount the landlord holds beyond the first full rental period counts toward that cap, whatever the lease calls it (MCL 554.602).

How long does a landlord have to return a security deposit in Michigan?

Within 30 days after the tenant moves out, the landlord must mail an itemized list of damages and return the balance. If the list isn’t sent on time, the full deposit is owed. The tenant must provide a forwarding address within 4 days of moving out to trigger the mailing duty (MCL 554.609, 554.611).

Is there a limit on late fees in Michigan?

Michigan has no statutory cap or required grace period. A late fee must be in the written lease and reasonable in amount; courts can refuse to enforce a fee that operates as a penalty rather than a fair estimate of the landlord’s cost.
