Mold in Rental Properties: Tenants and Landlords

Mold in a rental property sits at the intersection of two people's responsibilities, and that is what makes it complicated. The tenant lives with the problem every day, and the landlord owns the building and the systems that may have caused it. When neither side is sure who should act, the problem can sit for months while the growth spreads and the relationship between tenant and landlord gets worse.

This guide gives general information for tenants and landlords: how to report a problem, how to document it, and what an inspection covers. It is general information only, not legal advice, and questions about rights and obligations in Louisiana should go to a real estate professional or an attorney. Our mold inspection and testing page covers the first step, and homes in New Orleans and across Louisiana face the same questions.

What tenants should do first

A tenant who finds mold should report it promptly and in writing. Tenants should put the report in writing as well as calling, so there is a dated record showing when the landlord was told and what was found. The written report should set out what was found, where it sits, how large it looks, when it was first seen, and any leak, flooding or damp that could be behind it. Photographs, taken without disturbing the growth, should be kept with the report.

The tenant should also keep a record of what happens after the report: when the landlord responds, what is said, and what action is taken. If the landlord sends someone to look at the problem, the tenant should note who came, when, and what was said. A clear, dated record is useful whether the problem is fixed quickly or whether it becomes a longer discussion, and it costs nothing to keep.

What landlords should do

A landlord who receives a report of mold should take it seriously and act promptly, because a small problem left alone becomes a larger one, and a larger one costs more to fix and is harder to explain. The first step is an inspection, to find out what the problem is, how far it extends, and what caused it. The inspection should be done by someone who can map the moisture and identify the source, not by a quick look from the doorway.

The landlord should also think about the cause, not just the growth. A leak, a failed seal, a roof problem, a drainage issue, or a ventilation fault in the building are the landlord's responsibility to address in general terms, because they are part of the building. A problem caused by the tenant's use of the property, such as a window left open in the rain or a leak that was never reported, is a different matter, and the inspection findings help to tell the two apart.

Documenting the problem

Documentation matters for both sides. Photographs of the growth, the affected rooms, the apparent source of the water, and any damaged belongings, taken from a safe position and without disturbing the growth, create a record of the problem as it was. Dates matter too: when the problem was first noticed, when it was reported, and what was done in response. Keep copies of every message, every report, and every inspection finding.

Documentation also matters for the work that follows. An inspection report, a written scope of work, moisture readings and any test results are the records that show what was found and what was done. Both the tenant and the landlord should keep copies, because the records are useful if the problem returns, if the property is sold, or if the tenancy ends and the condition of the property is discussed.

Inspection and the next steps

An inspection is the step that moves the conversation from opinions to facts. It maps the problem: where the growth is, how far the moisture has spread, what materials are affected, and where the water came from. The findings give both sides a shared basis for deciding what to do next, and they prevent the discussion from becoming an argument about who is to blame. The scope of the work follows the findings, and the work follows the standard sequence of containment, removal, cleaning, drying and checking.

For a rental, a patch larger than about ten square feet is a professional job under EPA guidance, and the landlord should arrange it. The mold remediation page explains the process, and the mold removal page explains the removal stage. The inspection is the step that both sides should agree on first, because it gives them both the same facts.

Working together on the problem

The most useful advice for both sides is to treat the problem as a building problem first and a tenancy problem second. The growth is there because water got in, and the water got in for a reason that can be found and fixed. A tenant who reports promptly and in writing, and a landlord who inspects promptly and acts on the findings, will solve the problem faster and with less friction than a tenant who waits and a landlord who delays.

Homes in Baton Rouge and Lafayette are rented the same way, and the questions about rights and obligations should go to a professional. The practical summary is short: report promptly and in writing, document everything, inspect first, fix the source, and keep the records. That is the path that serves both the tenant and the landlord.

Mold and the end of a tenancy

When a tenancy ends, the condition of the property is looked at closely, and a mold problem that was never documented can become a dispute about who caused it and who should pay for it. A tenant who reported the problem promptly and in writing, and who kept photographs and records, is in a strong position, because the record shows when the problem was found and what was done about it. A landlord who inspected promptly and acted on the findings is in a strong position too, because the record shows the problem was dealt with. The records are what turn a dispute into a discussion.

The practical advice for both sides is to keep the records, and to share them. The tenant should keep copies of every report, every photograph, and every inspection finding. The landlord should keep copies of the inspection, the scope of work, the moisture readings, and any test results. When the tenancy ends, those records are the basis for a fair discussion about the condition of the property, and they are the reason a problem that was dealt with properly does not become a problem at the end of the tenancy.

Questions About Mold in Rental Properties: Tenants and Landlords

What should a tenant do when they find mold?

Report it promptly and in writing, describing what was found, where it is, how large it looks, and when it was first noticed, and mention any leak or flooding. Keep photographs and a record of what happens after the report.

What should a landlord do when mold is reported?

Take it seriously and act promptly. The first step is an inspection to find out what the problem is, how far it extends, and what caused it. A small problem left alone becomes a larger and more costly one.

Who is responsible for fixing mold in a rental?

That depends on the cause and on the terms of the tenancy, and questions about rights and obligations should go to a real estate professional or an attorney. In general terms, building faults such as leaks and roof problems are for the landlord, and the inspection findings help to tell the causes apart.

Why is an inspection important in a rental dispute?

Because it moves the conversation from opinions to facts. It maps the growth, the moisture and the source, giving both sides a shared basis for deciding what to do next, and the scope of the work follows the findings.

Your Next Step

If this guide matches what you found at home, the next step is a visit — not a guess. Call and describe what you found, and the visit is arranged from what you describe. The Mold Removal page explains what that service covers, and the mold remediation page explains how the full sequence works when mold has spread to more than one room.

Do not enter flooded rooms while you wait, and if water is leaking, turn off the shut-off valve for that fixture where you can reach it safely from dry ground.

Keep the guides on this site bookmarked: the first guide, the signs guide, and the preparation guide cover the checks worth repeating — after moving in, and after bringing used fixtures home.

Mold help is available across Louisiana. See mold remediation in Old Jefferson, LA for one local example, or find your town on the service areas page.
