Clues to Record
These observations help direct an inspection; they do not identify mold type, hidden extent or a medical cause.
- Dampness or visible growth that returns after cleaning or a claimed repair.
- A recurring musty odor, especially near a previously wet wall, cabinet, or floor.
- Soft, swollen, peeling, or discolored material; stains alone do not identify a mold species or show whether material is currently wet.

Minnesota mold law snapshot
Minnesota does not have a mold-specific statute, but habitability rules still apply.
Under Minnesota Statutes Section 504B.161, landlords have an implied covenant in every residential lease that the premises and all common areas are fit for the use intended by the parties. Landlords must keep the premises in reasonable repair during the term of the lease, maintain compliance with applicable health and safety laws, and keep premises reasonably energy efficient. These covenants cannot be waived by tenants and apply to all residential leases concluded or renewed since June 15, 1971. Recent 2023 legislative amendments expanded habitability protections to include common areas and added extermination requirements.

Repair Notices and Rent Decisions
Start with these Minnesota rules, then check the local regulations section and your property's coverage. A statutory notice period is not always a deadline for finishing every repair. Keep proof of notice and get local legal advice before changing rent payments or ending a lease.
How long does a Duluth landlord have to fix mold?
No universal mold-specific repair deadline was confirmed for Minnesota in the sources reviewed for this guide. Treat timing as notice-and-condition specific: document the mold and moisture source in writing, use the cited habitability or repair source, and get local code enforcement or legal aid advice before treating any deadline as fixed.

Can Duluth tenants withhold rent for mold?
Minnesota tenants may withhold rent through a rent escrow action under Minn. Stat. 504B.385. Tenants must first provide written notice to the landlord and wait 14 days for repairs. If repairs are not made, tenants deposit rent with the court rather than withholding it entirely. The court may order rent abatement, require repairs, or allow the tenant to break the lease. Simply withholding rent without court involvement is risky and may result in eviction.

Does mold in Duluth require relocation?
Unclear as a standalone statewide mold relocation benefit in the sources reviewed for this guide. If mold or remediation makes the unit unsafe or unusable, Minnesota tenants should look to the cited habitability, essential-services, condemnation, disaster, or lease-termination rules and ask legal aid whether rent abatement, substitute housing, temporary vacancy, or termination applies.

Does mold have to be disclosed in Duluth?
Minnesota does not have a specific mold disclosure requirement for landlords. However, landlords are generally prohibited from renting properties that have been condemned or deemed unfit for human habitation. If a landlord knows of conditions that would make the premises uninhabitable, including severe mold problems, failing to disclose this information could constitute fraud or breach of the implied warranty of habitability.
