Overview
Michigan does not have specific state statutes addressing mold in rental properties. However, tenants are protected under the implied warranty of habitability established by MCL 554.139, which requires landlords to maintain rental premises in a fit and habitable condition and comply with applicable health and safety laws. When mold results from a landlord's failure to address underlying issues like water leaks or moisture problems, the landlord may be held responsible under this general habitability standard.

Tenant Rights
Right to Habitable Premises
Tenants have the right to rental premises that are fit for use and in reasonable repair. Landlords must comply with all applicable state and local health and safety laws. If mold develops due to the landlord's failure to make repairs, the tenant may have remedies available.
[Michigan Courts Landlord-Tenant Law Benchbook - Habitability Covenants]
Right to Request Repairs
Tenants have the right to request repairs for issues that affect health and safety. While Michigan does not require written notice, providing written documentation is advisable to create a clear record of the request and timing.
Landlord Responsibilities
Maintain Fit and Habitable Premises
Landlords must ensure that the premises and all common areas are fit for the use intended by the parties. This includes addressing conditions that could lead to mold growth, such as water leaks, roof damage, plumbing issues, and inadequate ventilation.
Keep Premises in Reasonable Repair
Landlords have a statutory duty to keep rental premises in reasonable repair throughout the lease term. This obligation includes timely response to repair requests that could prevent mold growth if left unaddressed.
Remedies Available to Tenants
Rent Withholding
Available: Michigan courts have recognized rent withholding as a remedy for habitability violations. Tenants must provide written notice to the landlord of the problem and allow reasonable time for repairs. The withheld rent should be deposited into an escrow account. In cities enforcing the Housing Law of Michigan where a certificate of compliance has been suspended, tenants' duty to pay rent is suspended, but they must pay rent into an escrow account established by the enforcing agency.
Repair and Deduct
Available: Michigan tenants may have a right to make repairs and deduct the cost from rent, though this remedy is based primarily on common law rather than explicit statutory authority. Tenants should: (1) provide written notice to the landlord about the issue, (2) allow a reasonable time for the landlord to make repairs, (3) obtain estimates if the repair is complex or expensive, (4) have the work done by a professional or in a workmanlike manner, and (5) provide the landlord with copies of receipts. The repair cost should generally not exceed one month's rent. Given the lack of clear statutory guidance, consulting with an attorney before using this remedy is advisable.

Documentation and Escalation
Mold Risk in Michigan
Understanding Michigan's unique climate and environmental factors helps explain why mold can be a significant concern in rental properties.
Michigan's Great Lakes Climate
Michigan has a humid continental climate significantly influenced by the Great Lakes. The state receives 30-38 inches of precipitation annually, with lake-effect snow and moisture adding to humidity levels. The Great Lakes moderate temperatures but add substantial moisture to the air, particularly in lakeside communities. Summer humidity frequently exceeds 70%, and persistent cloud cover limits evaporation.
Great Lakes and Basement Mold Challenges
Michigan faces significant mold challenges due to Great Lakes humidity and the prevalence of basements. The Midwest has elevated rates of basement moisture problems compared to other regions. Michigan's combination of lake-effect moisture, heavy snowfall, and aging housing stock creates persistent mold concerns. Detroit and other urban areas have older housing particularly vulnerable to moisture issues.
Great Lakes Influence
Michigan is the only state surrounded by four of the five Great Lakes, creating unique moisture patterns. Lake-effect precipitation can be intense and localized. Lakeside communities experience persistent humidity and fog that can contribute to indoor moisture problems. The moderating effect of the lakes extends the mold growth season.
Aging Urban Housing
Michigan's urban areas, particularly Detroit, Flint, and Grand Rapids, have significant inventories of older housing. These structures often have inadequate ventilation, original plumbing, and basement moisture issues. Detroit's housing crisis has left many properties with deferred maintenance that exacerbates mold problems.
Common Mold Types in Michigan
Michigan is surrounded by four Great Lakes, creating unique moisture patterns with lake-effect precipitation and persistent humidity. Detroit, Flint, and Grand Rapids have significant older housing stock with deferred maintenance. Basement construction is standard throughout the state, and lake-effect snow melt contributes to spring moisture issues.
Stachybotrys chartarum
Black mold found in chronically water-damaged homes, particularly common in Detroit's aging housing with persistent moisture problems.
Aspergillus
Widespread throughout Michigan, found in HVAC systems and water-damaged materials. Thrives in Great Lakes humidity.
Cladosporium
Common in Michigan basements and bathrooms. Lake-effect moisture keeps humidity elevated in lakeside communities.
Penicillium
Frequently found in water-damaged materials, wallpaper, and carpeting in Michigan's older urban housing.
Fusarium
Found in flooding-damaged homes and in soil; enters buildings after basement flooding events common in Michigan.
Mold Professional Requirements in Michigan
Implied Warranty of Habitability
Michigan law establishes an implied warranty of habitability through MCL 554.139, which applies to every lease or license of residential premises. Under this law, landlords covenant that: (a) the premises and all common areas are fit for the use intended by the parties, and (b) they will keep the premises in reasonable repair during the term of the lease and comply with applicable health and safety laws of the state and local government. This warranty cannot be waived in leases shorter than one year. When mold growth results from a landlord's failure to maintain the property or address water intrusion, it may constitute a breach of this habitability covenant. [MCL 554.139 - Michigan Legislature]

Notable Mold Court Cases in Michigan
These cases have shaped mold litigation and tenant rights in Michigan. Understanding legal precedents can help inform your own situation.
Bailey v. Washington (Women's Huron Valley Prison Mold) (2019)
Summary: Federal lawsuit alleging pervasive toxic black mold at Michigan's only women's prison violated inmates' Eighth Amendment rights. U.S. District Judge Murphy described the facility as "infested with mold" that eats through brick and metal, drips from ceilings, and falls from air vents.
Outcome: MDOC denied qualified immunity (July 2025). Internal MDOC assessment documented widespread infrastructure failures and proposed $12M+ in repairs. Case on appeal to Sixth Circuit as of September 2025.
Significance: High-profile ongoing case highlighting systemic mold failures in state-run facilities. Demonstrates judicial willingness to hold institutions accountable for deliberate indifference to mold hazards.

Frequently Asked Questions
Does Michigan have specific laws about mold in rental properties?
No, Michigan does not have specific state statutes addressing mold in rental properties. However, mold issues are addressed through the general implied warranty of habitability under MCL 554.139, which requires landlords to maintain premises in a fit and habitable condition and comply with applicable health and safety laws.
Can I withhold rent if my Michigan rental has mold?
Michigan courts have recognized rent withholding as a potential remedy for habitability violations. You must provide written notice to your landlord about the mold issue and allow reasonable time for repairs. It is strongly recommended that you deposit the withheld rent into an escrow account rather than simply not paying, as this protects you in case the landlord files for eviction.
Is my Michigan landlord required to disclose mold before I rent?
No, Michigan does not have any statutes or regulations requiring landlords to disclose the presence of mold or prior mold problems to prospective tenants. Unlike lead paint, there is no federal or state-mandated mold disclosure requirement.
