MOLD DISCLOSURE: There are many types of mold. Inhabitable properties are not, and cannot be, constructed to exclude mold. Moisture is one of the most significant factors contributing to mold growth. Information about controlling mold growth may be available from your county extension agent or health department. Certain strains of mold may cause damage to property and may adversely affect the health of susceptible persons, including allergic reactions that may include skin, eye, nose, and throat irritation. Certain strains of mold may cause infections, particularly in individuals with suppressed immune systems. Some experts contend that certain strains of mold may cause serious and even life-threatening diseases. However, experts do not agree about the nature and extent of the health problems caused by mold or about the level of mold exposure that may cause health problems. The Centers for Disease Control and Prevention is studying the link between mold and serious health conditions. The seller, landlord, seller's agent, buyer's agent, or property manager cannot and does not represent or warrant the absence of mold. It is the buyer's or tenant's obligation to determine whether a mold problem is present. To do so, the buyer or tenant should hire a qualified inspector and make any contract to purchase, rent, or lease contingent upon the results of that inspection. A seller, landlord, seller's agent, buyer's agent, or property manager who provides this mold disclosure statement, provides for the disclosure of any prior testing and any subsequent mitigation or treatment for mold, and discloses any knowledge of mold is not liable in any action based on the presence of or propensity for mold in a building that is subject to any contract to purchase, rent, or lease.
Tenant acknowledges receipt of this disclosure, the listed results, and evidence of treatment, if any, by signing below. This disclosure does not waive Landlord's nonwaivable maintenance duties.
2. TENANT CARE AND REPORTING
Consistent with § 70-24-321, Tenant shall keep the occupied area reasonably clean and safe, dispose of waste safely, keep plumbing fixtures reasonably clean, use supplied facilities reasonably, and avoid damaging the premises.
Tenant shall promptly report leaks, standing water, persistent condensation, HVAC or exhaust failure, visible suspected growth, or persistent musty odor to [CONTACT / METHOD]. This is a contractual prompt-report term, not an invented Montana 24-hour statute.
3. LANDLORD RESPONSE AND ACCESS
Landlord shall investigate and address conditions within the duties stated in § 70-24-303, using qualified professionals when appropriate. The response plan is:
| Item | Plan / date / responsible person |
|---|---|
| Moisture source investigation | [________________________________] |
| Repair | [________________________________] |
| Sampling, if professionally recommended | [________________________________] |
| Cleaning or remediation | [________________________________] |
| Follow-up | [________________________________] |
| Temporary-use arrangement | [________________________________] |
Access must comply with § 70-24-312: except in an emergency or when impracticable, at least 24 hours' notice and reasonable-time entry. This Addendum does not invent a five-business-day sampling, remediation, clearance, or comparable-housing deadline.
4. COSTS AND LOSS OF USE
Repair, testing, remediation, personal-property loss, rent adjustment, insurance, and temporary-use issues will be determined from cause, lease terms, professional evidence, and nonwaivable law. No automatic charge to either party or mandatory testing protocol is created here.
5. STATUTORY RIGHTS PRESERVED
Nothing waives a chapter 24 right or remedy, disclaims an implied duty that law makes nonwaivable, limits liability for another party's purposeful misconduct or negligence, or indemnifies that liability or related costs or attorney fees. § 70-24-202.
No custom 72-hour cure or automatic lease termination applies. Any tenant-noncompliance termination must follow the applicable part of § 70-24-422 and the court process.
Potential attorney fees and costs are governed by § 70-24-442, not a one-sided addendum provision.
6. SIGNATURES

Real estate documents transfer ownership, define who can use a property, and record agreements between buyers, sellers, landlords, and tenants. Deeds, purchase agreements, leases, and easements have to be drafted to meet state recording requirements, and mistakes show up at closing or years later in title disputes. Good real estate paperwork moves transactions forward quickly and avoids the kind of problems that only surface when it is time to sell or refinance.
