Texas Mold Regulations & Disclosure Requirements

Texas has one of the most comprehensive mold regulatory frameworks in the United States. Unlike many states that leave mold oversight to a patchwork of local ordinances and general housing codes, Texas enacted dedicated mold legislation under Senate Bill 876 in 2003, creating a formal licensing and oversight system that governs everyone from home sellers to professional remediation contractors. This framework is administered by the Texas Department of Licensing and Regulation (TDLR), which oversees the licensing of mold assessment consultants, mold remediation contractors, and related technicians throughout the state.

Texas's humid Gulf Coast climate, frequent flooding events—most recently amplified by hurricanes and severe storms across Houston, Beaumont, and the Rio Grande Valley—and its massive residential real estate market make mold a particularly urgent concern. According to the Texas Department of Insurance, mold-related homeowner claims have consistently ranked among the costliest property damage claims in the state. The Texas Legislature responded by creating mandatory licensing, consumer protections, and enforceable disclosure requirements that set a standard most other states have not matched.

Whether you are a homeowner in San Antonio dealing with black mold after a plumbing leak, a landlord in Dallas managing tenant complaints, or a prospective buyer reviewing a home in Houston, understanding Texas mold regulations is essential for protecting your health, your legal rights, and your financial interests. This guide breaks down every major component of the Texas mold regulatory system so you can make informed decisions.

Mold Disclosure Laws in Texas

Texas imposes clear mold disclosure obligations on home sellers through the Texas Property Code and the standard Seller's Disclosure Notice promulgated by the Texas Real Estate Commission (TREC). Sellers of residential property containing one to four units are required by law to complete this disclosure form, which asks direct questions about known water damage, water intrusion, and the presence of mold or mildew. Sellers must answer these questions to the best of their knowledge and belief, and knowingly providing false or misleading answers exposes them to significant legal liability.

Under the Texas Deceptive Trade Practices—Consumer Protection Act (DTPA), a seller who conceals known mold problems or misrepresents the condition of the property can face claims for actual damages, mental anguish damages, and in cases of knowing or intentional conduct, up to three times the actual damages. Real estate agents also have an independent duty to disclose known material defects, which can include mold that has been brought to their attention.

For rental transactions, Texas law does not require landlords to provide a formal mold disclosure notice before executing a lease in the same way that sellers must for purchase transactions. However, landlords remain liable for habitability defects they know about, including mold, and concealing such conditions can expose them to civil liability and claims under the DTPA. Some municipalities, including Houston, have adopted local health and housing codes that create additional notification obligations for landlords when units have known mold issues.

Buyers in Texas are strongly advised to hire a licensed mold assessment consultant before closing on any property that shows signs of water damage, musty odors, or prior flooding. Real estate disclosure forms capture only what sellers know and choose to reveal—an independent professional assessment provides the most reliable picture of actual mold conditions before a transaction closes.

Mold Remediation Contractor Licensing in Texas

Texas stands apart from most states by requiring formal, state-issued licenses for professionals who perform mold assessment and mold remediation work. The Texas Department of Licensing and Regulation (TDLR) administers the Mold Assessors and Remediators licensing program under Texas Occupations Code Chapter 1958 and the associated administrative rules in 16 Texas Administrative Code Chapter 78.

The Texas mold licensing system recognizes four primary license categories:

• Mold Assessment Consultant (MAC): The highest-level assessment license, required for individuals who independently perform mold assessments, develop remediation protocols, and issue post-remediation verification reports. Applicants must meet education and experience requirements and pass the TDLR examination.
• Mold Assessment Technician (MAT): Technicians who perform mold assessments under the supervision of a licensed MAC. They must also pass a state examination and meet training prerequisites.
• Mold Remediation Contractor (MRC): Companies or individuals who physically perform mold remediation work. They must hold a TDLR license and carry the required insurance. An individual performing remediation work on-site must be a licensed Mold Remediation Worker (MRW) or operate under a licensed contractor.
• Mold Remediation Worker (MRW): Individuals employed by licensed contractors to perform hands-on remediation tasks.

In addition to TDLR licensing, many Texas mold professionals hold voluntary industry credentials that signal advanced competency. The Institute of Inspection, Cleaning and Restoration Certification (IICRC) offers the Applied Microbial Remediation Technician (AMRT) certification, widely recognized across the industry. The American Council for Accredited Certification (ACAC) offers credentials including the Certified Mold Inspector (CMI) and Certified Mold Remediator (CMR). While these certifications are not legally required in Texas, they indicate that a contractor has invested in professional training beyond the state minimum.

Texas law explicitly prohibits the same company or individual from performing both the assessment and remediation on the same project. This separation of duties protects consumers by ensuring that whoever recommends the work has no financial interest in whether or how much remediation is performed—a critical consumer protection that many other states lack.

Consumers can verify a contractor's current TDLR license status through the TDLR License Search tool available on the agency's official website. Hiring an unlicensed mold contractor in Texas is illegal and leaves the property owner with no regulatory recourse if the work is performed improperly.

Texas Mold Inspection Standards

Mold inspections in Texas must be performed by a licensed Mold Assessment Consultant (MAC) or Mold Assessment Technician (MAT) working under MAC supervision. The inspection process is governed by TDLR rules, which establish minimum standards for how assessments are conducted, documented, and reported.

A compliant Texas mold assessment typically includes a thorough visual inspection of the property, moisture mapping using calibrated meters, and collection of air and surface samples when warranted by observed conditions. Samples must be sent to an accredited third-party laboratory for analysis. Texas does not establish a numeric “safe” mold level for indoor air—no federal standard currently exists either—so inspectors evaluate results by comparing indoor spore counts and species to outdoor control samples and by assessing the types of mold species present. Elevated concentrations of moisture-indicator species such as Stachybotrys chartarum (commonly called black mold), Chaetomium, or Aspergillus/Penicillium relative to outdoor levels are considered significant findings.

After an assessment identifies mold problems, the MAC must prepare a written Mold Remediation Protocol that specifies the scope of work, the containment and engineering controls required, and the clearance criteria the remediation contractor must meet. Once remediation is complete, a separate licensed MAC (not the one who oversaw the original assessment) must perform a Post-Remediation Verification (PRV) inspection to confirm that mold has been successfully removed and that moisture conditions have been corrected. The PRV report must be provided to the property owner.

Texas inspection standards align closely with industry guidelines published by the IICRC S520 Standard for Professional Mold Remediation and the EPA's Mold Remediation in Schools and Commercial Buildings guidance document. Inspectors working in Texas are expected to be familiar with these frameworks, which address containment requirements, personal protective equipment (PPE) standards, and documentation protocols.

Properties with a history of flooding—particularly in the Houston-Galveston area following hurricanes Harvey, Imelda, and subsequent storm events—often require particularly thorough assessments because flood water introduces contaminants and promotes rapid mold colonization within wall cavities, beneath flooring, and inside HVAC systems. Licensed Texas MACs are trained to identify hidden moisture reservoirs that may not be visible during a standard walk-through.

Landlord Mold Responsibilities in Texas

Texas landlords bear significant legal responsibility for mold conditions in their rental properties. The foundation of tenant protection is Texas Property Code Section 92.056, which requires landlords to make a diligent effort to repair conditions that materially affect the physical health or safety of an ordinary tenant. Courts and attorneys general guidance have consistently interpreted active, significant mold growth—particularly mold resulting from unaddressed water intrusion—as meeting this threshold.

To trigger a landlord's repair obligation under Texas law, a tenant must follow a specific process: provide written notice of the mold condition to the landlord or property manager, and allow a reasonable time for repair. The Texas Property Code establishes a default repair timeline of seven days from the date of written notice for conditions that materially affect health or safety, though courts may consider whether seven days was reasonable given the complexity of the repair. Sending notice via certified mail creates a documented record that is critical if the matter later proceeds to litigation.

If a landlord fails to remediate mold within the required timeframe after proper notice, Texas tenants have several legal remedies available:

• Lease termination: Tenants may terminate the lease without penalty if the landlord fails to make the required repair within the statutory period.
• Rent deduction: Tenants may have the repair performed by a licensed contractor and deduct the cost from rent, subject to statutory caps (generally one month's rent or $500 per repair, whichever is greater).
• Civil lawsuit: Tenants may sue for actual damages, one month's rent plus $500, attorney's fees, and court costs.
• Rent escrow: In some circumstances, tenants may pay rent into an escrow account rather than to the landlord until conditions are corrected.

It is important to note that Texas landlord mold liability applies when mold results from conditions within the landlord's control, such as roof leaks, plumbing failures, or inadequate ventilation. When mold results solely from a tenant's own behavior—such as blocking ventilation, creating excessive humidity, or failing to report leaks promptly—the tenant may bear greater responsibility. Lease agreements in Texas often include mold addenda that clarify maintenance responsibilities and require tenants to report moisture issues promptly.

Houston's high baseline humidity, combined with aging apartment stock and frequent storm-related flooding, makes landlord mold compliance particularly pressing in that market. Austin's booming rental market has similarly seen increased tenant complaints about mold in older multifamily properties. San Antonio and Dallas landlords operating older housing stock face comparable challenges. Across Texas, tenant advocacy organizations and local legal aid offices report that mold complaints are among the most common habitability issues raised by renters.

If you are dealing with a potential mold problem in your Texas home, rental property, or commercial building, acting quickly is essential. Mold colonies can spread rapidly in Texas's warm, humid climate, and delay typically increases both remediation costs and health risks. The right first step is connecting with a licensed Texas mold assessment consultant who can evaluate your property and recommend an appropriate course of action based on what they actually find—not a sales pitch.

When evaluating Texas mold contractors, look for the following:

• Valid TDLR license: Confirm current licensing for both assessment and remediation work through the TDLR online lookup tool before signing any contract.
• Separation of duties: Ensure that the company performing your assessment is not the same company proposing to do the remediation. This is required by Texas law and protects you from conflicts of interest.
• Insurance: Licensed Texas mold remediation contractors must carry general liability insurance and workers' compensation. Request certificates of insurance before work begins.
• Written protocol and clearance: A professional contractor will work from a written remediation protocol and will not consider the job complete without a post-remediation verification by an independent MAC.
• Industry credentials: IICRC or ACAC certifications in addition to TDLR licensing indicate a higher level of professional commitment.
• References and reviews: Ask for local references from Texas projects and check online reviews specific to mold remediation work.

Frequently Asked Questions About Mold Regulations in Texas

Does Texas require sellers to disclose mold when selling a home?

Yes. Texas law requires home sellers to complete a Seller's Disclosure Notice issued by the Texas Real Estate Commission (TREC) that includes questions about known water damage, leaks, and mold. Sellers who knowingly conceal mold or water intrusion problems can face significant legal liability under the Texas Deceptive Trade Practices Act, including up to three times actual damages in cases of intentional misconduct. Buyers should always hire a licensed mold assessment consultant for an independent inspection before closing, regardless of what the disclosure form states.

Do mold remediation contractors in Texas need a license?

Yes. Texas is one of a small number of states with a formal, state-administered mold licensing program. The Texas Department of Licensing and Regulation (TDLR) requires mold assessment consultants, mold assessment technicians, mold remediation contractors, and mold remediation workers to hold valid TDLR licenses. Performing mold assessment or remediation work without the appropriate license is a violation of Texas Occupations Code Chapter 1958 and can result in administrative penalties. Always verify a contractor's TDLR license status before hiring.

What are a landlord's mold responsibilities in Texas?

Texas landlords must maintain rental properties in a condition that does not materially affect the physical health or safety of tenants, under Texas Property Code Section 92.056. Mold caused by plumbing failures, roof leaks, or other structural deficiencies is generally the landlord's responsibility to remediate. After receiving written notice from a tenant, landlords typically have seven days to begin addressing the problem. Failure to do so can entitle tenants to terminate the lease, deduct repair costs from rent, or pursue a civil lawsuit for damages, rent credits, and attorney's fees.

Who can perform a mold inspection in Texas?

Texas law restricts formal mold assessments to individuals holding a valid Mold Assessment Consultant (MAC) or Mold Assessment Technician (MAT) license issued by the Texas Department of Licensing and Regulation. A general home inspector, HVAC technician, or unlicensed contractor cannot legally perform a formal mold assessment or issue a remediation protocol in Texas. The same firm that performs the assessment is also legally prohibited from performing the remediation on the same property, ensuring an independent check on the scope and cost of any work recommended.
