Start With Your Bismarck Property
Track whether a wet area follows thaw, rain, or use of plumbing. Include structural damage or electrical equipment near water as separate safety concerns and avoid entering an unsafe space.
Bismarck building and fire code contacts
The city's official page provides separate Building Division and Fire Division contacts. It is a code-information resource, not a promise of indoor mold testing or a housing complaint finding.
Before you contact them:Prepare the address, defect description, photos, and proposed repair scope. Ask which city office can evaluate the existing condition and whether permitted repair inspections are required.

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.

State Laws and Rights
Check North Dakota notice requirements and the coverage of your tenancy before using a rent remedy or ending a lease. The local reporting contact above can address only the issues within its stated scope.
North Dakota mold law snapshot
North Dakota does not have a mold-specific statute, but habitability rules still apply.
Under N.D.C.C. Section 47-16-13.1, landlords must comply with applicable building and housing codes materially affecting health and safety, make all repairs necessary to put and keep the premises in a fit and habitable condition, keep common areas clean and safe, and maintain all electrical, plumbing, sanitary, heating, ventilating, air-conditioning, and other facilities in good and safe working order. The landlord must also provide outlets for waste disposal and supply running water, hot water, and reasonable heat. This warranty of habitability cannot be waived or modified by the parties to the lease agreement. While mold is not specifically mentioned, conditions that promote mold growth (such as plumbing leaks, inadequate ventilation, or water intrusion) would violate these habitability standards.

Repair Notices and Rent Decisions
Start with these North Dakota 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 Bismarck landlord have to fix mold?
No universal mold-specific repair deadline was confirmed for North Dakota 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 Bismarck tenants withhold rent for mold?
North Dakota law does not explicitly authorize rent withholding as a remedy for habitability violations. Simply withholding rent without making repairs is not a permissible option. Instead, tenants must use other remedies such as repair-and-deduct under N.D.C.C. Section 47-16-13, vacating the premises, or pursuing damages in court. Tenants who withhold rent without legal authorization risk eviction for nonpayment. While the North Dakota Supreme Court in South Forks Shopping Ctr. v. Dastmalchi (1989) acknowledged that a breach of habitability may justify a tenant in not paying some or all rent, the court did not permit rent withholding in that case.

Does mold in Bismarck 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, North Dakota 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 Bismarck?
North Dakota does not have a statewide mold disclosure statute for rental properties. Landlords must provide a signed statement of the condition of the premises at move-in under N.D.C.C. Section 47-16-07.2. Federal lead-based paint disclosure requirements still apply to pre-1978 properties.
