Texas Changed Its Mold Law in 2025. Its Own Rulebook Still Disagrees With Itself.

Here is a subtlety that trips up even careful researchers: a citation can be real, correctly numbered, and still out of date. Texas is the cleanest example we found.

S.B. 1255, effective September 1, 2025, did two things. It removed “mycotoxins” from the statutory definition of mold, and it repealed the supervised-employee exemption in Occ. Code §1958.102(b) — meaning employees assisting on mold jobs now need their own credential rather than working unlicensed under supervision.

The rulebook lag

Texas's administrative rules (16 TAC ch. 78) still define mold to include mycotoxins and still assume the repealed exemption. The statute says one thing; the agency's own rules say another. TDLR has formally noticed the chapter for review, but until that finishes, Texas has a genuine internal contradiction on the books.

Why we flag it

When we first verified Texas, a citation check passed — every section existed and said what we claimed. It took a separate currency check to catch that the quoted text had been superseded months earlier. It's the reason our verification process now treats “does this cite exist?” and “is this cite current?” as two different questions.
