When a tenant reports suspected mold or persistent moisture, acknowledge the concern and focus first on what is wet and why. Record the location and timeline, arrange an appropriate assessment, and address any active water source before mitigation or drying. Ask occupants not to disturb suspected growth or open materials. Keep them informed about access, work-area controls, planned activities, and what remains unknown. A report calls for investigation—not a diagnosis, a health-outcome promise, or an automatic decision about whether anyone should stay or leave.
1. Acknowledge the report and make a useful record
Thank the tenant and ask what they noticed, where and when it began, whether it has changed, and whether there is active water, a recurring leak, dampness, odor, or prior water damage. Photos may help if they can be taken without touching or moving affected materials. Record the date received, room or area, observed condition, moisture/leak history, active-water status, and access concerns. Keep the original report and follow-up in the property file.
Washington State Department of Health guidance says renters should promptly notify landlords in writing about leaks or moisture buildup due to building problems. Preserve the written report and response, but do not treat this article as legal advice or an interpretation of anyone’s duties. For a specific dispute or legal question, consult official Washington resources or qualified counsel. [1]
If water is still flowing, call Pacific Restoration at (360) 327-8778. Pacific Restoration handles getting a plumber involved to stop the source before mitigation or drying; it does not provide in-house plumbing repair. Call 911 only for immediate danger. For moisture that is not actively flowing, record whether it appears ongoing, intermittent, or historical and arrange an appropriate assessment.
2. Do not ask tenants to investigate inside the building
Do not ask occupants to scrape suspected growth, remove trim, lift flooring, pull back carpet, open walls, or peel wallpaper to check behind it. EPA notes that mold may be hidden beneath or behind materials and that disturbing a suspected hidden area can release material into the air. Record what is observable without calling it a confirmed mold identification; an appropriate assessment can establish what inspection is needed. [2][3]
If the tenant raises a health concern, acknowledge it without diagnosing or promising an outcome, and suggest they consult a health professional about personal medical questions.
3. Address moisture, then coordinate the right path
A durable response must address the moisture source; cleaning or removing material without correcting the water problem can allow conditions to recur. Depending on findings, the path may include water mitigation, water extraction, Advanced Structural Drying, moisture documentation, restoration-path coordination, mold remediation, or a combination. Pacific Restoration offers these services; this is not a commitment to a particular scope before assessment. [3]
Learn about water mitigation and mold remediation. Pacific Restoration serves all of Clark County and all of Cowlitz County, Washington. Calls and dispatch are available 24/7 only for water mitigation and Advanced Structural Drying; mold remediation is not a 24/7 service. See Cowlitz County water mitigation or browse the guides.
4. Explain access, work boundaries, and updates
Before work, explain what is known, what needs inspection, how access will be coordinated, and the planned work area and activities. Where part of the assessed scope, describe containment or protective controls, expected equipment or noise, and how changes will be communicated. Do not tell occupants that an area is safe or that they can stay or must leave based on this article alone; this article cannot determine occupancy for a particular situation. Follow site-specific instructions from emergency authorities and appropriately qualified professionals.
EPA Chapter 3 recommends planning around affected area and materials, moisture-source correction, occupant communication, and appropriate containment and protective equipment. In some cases it says temporary relocation may be considered based on factors such as affected area, reported health effects, debris exposure, and disruption. The chapter is written for schools and commercial buildings: it provides general planning context, not housing law or a universal rental-occupancy procedure. [2]
Provide updates after assessment, when scope or work areas change, if additional affected materials are found, and at completion. Explain what changed and the next step rather than leaving the tenant to infer progress from equipment or contractor activity.
5. Close out with records—and be candid about uncertainty
Document assessment findings, moisture observations, source-control status, work performed, materials addressed, available moisture documentation, and follow-up needs. Tell the tenant what was completed, what remains, and whether another visit or restoration step is planned. Do not present completion as proof of a health outcome or guarantee the condition will not return. If the source, concealed materials, or full extent could not be confirmed, say so and note the next step for resolving that uncertainty.
FAQs
Should a tenant clean or remove suspected mold before inspection?
No. Ask them not to disturb growth or open, peel, or remove materials. Record the condition and arrange an appropriate assessment. [2][3]
Does one report or photo show the full scope?
No. A report is a starting point. Assessment considers the affected materials, moisture source, and whether hidden areas may be involved; the plan may need to change if new information appears. [2][3]
Does a mold report automatically mean the tenant must leave?
No universal occupancy decision can be made from a report alone. Do not promise that anyone can safely occupy—or must vacate—a unit based on this article.
What belongs in the property file?
Keep the report and date, room or area, observed condition, moisture/leak history, access coordination, assessment and work updates, available moisture documentation, completion notes, and unresolved questions or follow-up.
