Texas Law & Licensing

History: the 2007 DSHS rules (25 TAC Chapter 295)

Historical Sources: 25 TAC Chapter 295 (2007), 16 TAC Chapter 78

In plain English

Texas began licensing mold work in 2004 under House Bill 329 (2003). Until 2017 the Department of State Health Services ran the program, and its rules were 25 TAC §§295.301–295.338, last amended May 20, 2007. The program moved to TDLR in 2017, and the rules were re-adopted as 16 TAC Chapter 78 effective November 1, 2017.

Much carried over — the 25-square-foot line, protocols and work plans, the 10-day certificate, the five-year seller rule — but details changed: for example, the 2007 rules required ownership changes to be reported within 10 days (now 30) and violations to be reported by the next business day (now "promptly"). If a report or certificate cites Chapter 295, it was written under the old rules. Current work follows Chapter 78.

Key points

  • 25 TAC 295: DSHS rules, superseded.
  • 16 TAC 78: current TDLR rules (from Nov 1, 2017).
  • Old reports may cite the old section numbers.

The Texas Mold Assessment and Remediation Rules (TMARR) were originally prepared and became effective on May 16, 2004, as a result of House Bill 329 passed by the 78th Texas Legislature, Regular Session, in 2003. This bill was codified in the Texas Occupations Code, Chapter 1958. In 2005, the 79th Texas Legislature, Regular Session, passed House Bills 74, 1328 and 2746 that amended the Texas Occupations Code, Chapter 1958. The TMARR were revised based on these three bills and these revised rules became effective May 20, 2007. The TMARR are part of the Texas Administrative Code (TAC), specifically 25 TAC §§295.301-295.338.
