Understanding Texas Mold Remediation Regulations

Why Texas Has Strict Mold Laws

Texas was one of the first states in the country to establish a formal regulatory framework for mold assessment and remediation, and for good reason. The combination of high humidity in Central and East Texas, frequent flooding from severe weather events, and a housing stock with many older homes creates conditions where mold problems are both common and serious. The Texas Department of Licensing and Regulation (TDLR) has enforced mold licensing requirements since 2004 under the Texas Occupations Code, Chapter 1958.

For Austin homeowners dealing with mold after water damage, flood, or persistent humidity issues, understanding these regulations is essential — not just for legal compliance, but to protect yourself from unlicensed contractors who may perform substandard work that leaves mold behind or spreads it to previously unaffected areas.

Who Must Be Licensed in Texas for Mold Work

Texas requires separate licensing for mold assessment and mold remediation, and the same person or company generally cannot perform both roles on the same project — this separation of roles is intentional, designed to prevent conflicts of interest where a contractor assesses a property and then recommends far more remediation work than is actually necessary.

Mold Assessment Consultants (MAC) are licensed by TDLR to inspect properties, collect samples, analyze conditions, and write mold remediation protocols. They must complete 40 hours of initial training, pass a state exam, and maintain continuing education.

Mold Remediation Contractors (MRC) are licensed to actually perform the physical remediation work — containment setup, HEPA vacuuming, removal of contaminated materials, cleaning, and post-remediation clearance. They must have their own TDLR license and may not take direction from the same MAC who assessed the project.

Always ask any contractor you hire to show you their current TDLR license before any work begins. You can verify license status at the TDLR website using the contractor's license number.

The Mold Remediation Protocol: What It Must Include

Before any remediation work begins on a project above a certain size (generally more than 25 contiguous square feet of visible mold), a licensed MAC must prepare a written Mold Remediation Protocol. This document must include the scope of the mold problem, the work procedures to be used, the personal protective equipment required for workers, clearance criteria that must be met before the project is considered complete, and waste disposal procedures.

Be wary of any contractor who wants to begin tearing out materials or applying antimicrobial chemicals before a formal protocol is in place. Skipping this step is not just a regulatory violation — it often results in incomplete remediation where hidden mold colonies are left behind, or mold spores being dispersed to other areas of the home during demolition.

Post-Remediation Verification

Under Texas law, after remediation is complete, a licensed MAC (different from the one who wrote the original protocol, or the same one if no conflict of interest) must conduct a post-remediation verification. This involves visual inspection and, if warranted, air sampling or surface sampling to confirm that mold levels inside the home have returned to normal background levels comparable to outdoor air.

The remediation contractor must provide you with a written Certificate of Mold Damage Remediation, signed by the licensed MAC who conducted the post-remediation verification. This document is increasingly required by real estate agents and buyers if you sell your home in the future, and it is your proof that the work was done properly and completely.
