Short answer: Idaho Code § 6-320 requires landlords to provide waterproofing and weather protection, keep plumbing, heating and ventilation working, and maintain the premises so they're safe and healthy. Idaho Legal Aid explains that a tenant should give written notice, and if the landlord doesn't take steps to fix a qualifying problem like mold within three days, the tenant can sue for damages and repairs. There's no general right to withhold rent. This is general information, not legal advice.
What Idaho Code § 6-320 requires
The statute lets a tenant bring a court action against a landlord who fails to do certain things after written notice, including:
- Provide reasonable waterproofing and weather protection
- Maintain electrical, plumbing, heating, ventilation and sanitary facilities in good working order
- Maintain the premises so the tenant's health and safety aren't materially affected
- Comply with applicable building, housing and health codes
- Install working smoke detectors
Mold shows up under several of these: a roof or plumbing leak is a waterproofing or plumbing failure, a broken bath fan is a ventilation failure, and significant growth can affect health and safety. Idaho Legal Aid's healthy housing guidance specifically says mold can make a unit uninhabitable and trigger the landlord's duty to repair. For most Landlord Mold Laws Nampa, ID questions, § 6-320 is the starting point.
How the three-day notice works
- Tenant gives written notice describing the problem and asking for repair.
- The landlord has three days to take steps to fix it. Idaho Legal Aid notes that the landlord must begin addressing the condition, though a full repair can take longer.
- If nothing happens, the tenant can file in court for damages and specific performance, an order requiring the repair. Idaho's court self-help forms walk tenants through this.

Tenant duties and landlord duties
| Landlord | Tenant |
|---|---|
| Fix leaks, roof and plumbing problems | Report leaks and mold promptly, in writing |
| Keep bath fans, heating and ventilation working | Use bath fans and range hoods, and don't block vents |
| Address mold caused by the building | Clean small surface mold and condensation they cause |
| Return the deposit within 21 days (up to 30 if agreed) under § 6-321 | Avoid damage beyond normal wear and tear |
Disputes usually come down to cause: was it a leak in the building, or moisture from how the unit was used? That's where neutral documentation of rental mold disputes helps both sides.
What this looks like in Nampa rentals
Canyon County has a large share of small landlords, many owning one or two homes. The mold cases we see in rentals are mostly crawlspace moisture from irrigation, bathroom mold from fans that don't vent outside, window condensation in older units during inversion weeks, and leaks under sinks. Most are fixable quickly once someone finds the source.

Landlord Mold Laws Nampa, ID: questions
Does Idaho require landlords to test for mold?
No. Idaho law doesn't require mold testing or set mold limits. The duty is to repair conditions that affect health and safety, such as leaks and the mold they cause.
Can a tenant withhold rent for mold in Idaho?
Generally no. Idaho's remedy is a court action after written notice. Withholding rent can lead to an eviction case. Get legal advice first.
Do landlords have to disclose past mold to new tenants?
Idaho law doesn't have a specific mold disclosure rule for rentals. Concealing a known hazard can still create liability. Many landlords document turnover inspections to protect themselves.
