What does it do?
SB1255 changes Texas’s mold-assessment and remediation law in two different directions: it exempts post-disaster demolition from this chapter, but removes an employee’s statutory licensing exemption based on supervision by a license holder. Signed June 20, 2025, it took effect September 1, 2025 and applies only to conduct on or after that date; earlier conduct remains governed by prior law. Final law, sections 2 and 4–6; Official history.
The new exemption is for demolition of a structure after a fire or other disaster. It is an exemption from the mold-regulation chapter, not an exemption from every safety, environmental or demolition requirement. It does not say that all ordinary repairs or every mold-cleanup project after water damage is exempt. The chapter otherwise concerns mold-related activities affecting indoor air quality. Final law, section 2; Existing chapter scope and exemptions.
The repealed subsection previously allowed an employee of a license holder to perform mold assessment or remediation without a license while supervised under agency rules. After its repeal, supervision alone no longer supplies that statutory exemption. Other exemptions remain, including the provision for remediation projects affecting less than 25 contiguous square feet and separately conditioned owner/tenant or small-residential-property provisions. The act does not repeal every exemption or eliminate the commission’s authority to regulate employee supervision and registration. Final law, section 4; Prior exemption text and remaining exemptions; License and supervision rules; Employee registration authority.
What changed along the way?
The act also removes the explicit word “mycotoxins” from the statutory definition of mold. The definition still includes living or dead fungi and related products or parts, including spores and hyphae. This is a change to the wording of the regulatory definition, not a scientific finding that toxins are harmless or a statement that every related product is outside the remaining language. It also corrects the advisory board’s wording from “standards or performance” to “standards of performance.” Final law, sections 1 and 3; Prior definition; Prior advisory-board wording.
The introduced, Senate committee, Senate-passed, House committee and enrolled substantive texts match.

Who could benefit—and who could bear the costs?
Post-disaster demolition operators gain the stated exemption from this mold-regulation chapter. Mold-service businesses and employees who relied only on supervised-employee status must account for the removal of that exemption, while clients retain the remaining licensing framework for covered work. The act does not prove a particular cleanup is safe, promise cheaper service, or determine an individual worker’s qualification under agency rules and other exemptions. Final law; Licensing framework; License qualifications and insurance rule authority.
The March 22 fiscal note anticipates no significant state fiscal impact, assuming existing resources can absorb costs, and no local-government fiscal impact. It does not estimate private training, licensing or demolition savings and costs. The act makes no appropriation. Fiscal note.
