Mold is one of the most serious — and most contested — habitability issues in Texas rentals. Texas's hot, humid climate creates ideal conditions for mold growth, and mold infestations can cause serious respiratory problems, allergic reactions, and other health issues. When mold appears in a rental unit, the question of who is responsible and what must be done is governed by a combination of Texas Property Code provisions, state health regulations, and the specific facts of how and why the mold developed.
This guide explains what Texas law says about mold in rentals, when the landlord is legally required to remediate, how to document a mold problem, what remedies are available to tenants, and what to do if the landlord refuses to act.
Texas does not have a residential tenant-specific mold remediation statute analogous to those in some other states. Instead, mold issues are addressed through the general habitability framework of TPC §92.052, which requires landlords to repair or remedy any condition that "materially affects the physical health or safety of an ordinary tenant."
Texas does have regulatory standards for mold remediation in general — the Texas Department of Licensing and Regulation (TDLR) regulates mold assessment and remediation contractors under the Texas Occupations Code and related administrative rules. Mold remediation contractors in Texas must be licensed by TDLR for work on structures (with limited exceptions for small areas).
The landlord's responsibility for mold depends heavily on the source of the moisture that caused the mold. Texas courts and general habitability principles draw a distinction between:
If the mold resulted from:
…then the landlord is responsible for both fixing the underlying moisture source and remediating the mold. The mold is a direct consequence of a condition the landlord was required to maintain.
If the mold resulted from:
…the landlord may argue that the tenant caused the condition and is therefore responsible under TPC §92.052(b), which exempts the landlord from the repair duty for conditions caused by the tenant.
In practice, mold causation is often disputed. Many mold cases involve both a structural moisture intrusion (landlord's problem) and tenant behavior that worsened the situation. The legal outcome often turns on which cause was primary.
Not all mold is the same. Some mold species are more toxic than others, and the health effects of mold exposure depend on the species, the extent of the infestation, and the individual's sensitivity. Common health effects of mold exposure include:
If you or a family member has developed health problems that you believe are related to mold in your rental, see a doctor and document the health issues in your medical records. This documentation becomes important evidence if you pursue legal remedies against the landlord.
Photograph and video all visible mold — every affected area, from multiple angles, with something in the frame for scale. Note the date of discovery. If the mold has been growing for some time (visible growth patterns, discoloration around edges), photograph the extent of the growth. If there are visible water stains that predate the mold or ongoing leaks, document those too.
Under TPC §92.056, you must give the landlord written notice of the condition before any of the legal remedies become available to you. Describe the mold's location, the apparent extent of the infestation, and any health symptoms you or your family have experienced. State that you believe the mold constitutes a condition that materially affects health or safety under TPC §92.052. Send via text, email, or certified mail, and keep documentation.
If you can identify the source of moisture (a dripping pipe, a roof leak that caused ceiling damage, condensation from a non-functioning HVAC system), include that in your notice. The landlord must fix the underlying moisture source, not just paint over or superficially remove the mold — because mold will recur if the moisture source isn't eliminated.
Many Texas cities have housing code enforcement that can inspect rental units for mold and habitability violations. A code enforcement inspection creates an official government record of the condition that is difficult for landlords to dispute. In some cities, code enforcement can compel remediation. Contact your city's code enforcement or housing department. The Texas Department of Health Services may also have jurisdiction in some circumstances.
If the landlord disputes the presence or severity of mold, or if you are dealing with a serious health issue, consider hiring a licensed mold assessment contractor (TDLR-licensed) to conduct air quality testing and a written assessment. This professional documentation is powerful evidence in legal proceedings. Costs vary but typically range from $200–$500 for a basic assessment.
After receiving proper written notice of a mold condition, the landlord must make a diligent effort to address the problem within a reasonable time. For serious mold affecting health — particularly for vulnerable individuals, or extensive infestations — the reasonable time may be shorter than the typical 7-day standard for ordinary repairs.
Adequate remediation means:
Simply painting over mold or bleaching surface mold without addressing the moisture source does not constitute adequate remediation. If the landlord does this and the mold recurs, they have failed to make adequate repairs and you can exercise remedies again after giving new written notice.
If the landlord fails to address a serious mold condition within a reasonable time after proper written notice, and your rent is current, you have the same remedies available under TPC §92.056 as for any other habitability failure:
For serious mold infestations that cause health harm or force you to temporarily relocate, actual damages can be significant — hotel costs, restaurant meals, storage costs, medical bills, and the cost of replacing mold-damaged personal property can add up quickly.
If mold is present in your unit, take steps to protect your belongings:
The cost of replacing mold-damaged property may be recoverable as actual damages if the landlord's failure to make repairs caused the mold.
Most standard renter's insurance policies do not cover mold damage unless the mold resulted directly from a covered peril (such as a sudden pipe burst). Review your renter's insurance policy carefully. If you have a policy, notify your insurer of the mold situation as soon as possible so they can evaluate coverage. Even if coverage is limited, your insurer may support your legal claim against the landlord.
