Steps

  1. Confirm the current edition is the 4th edition (2024), ANSI-approved, superseding the 2015 3rd edition
  2. Purchase the standard through IICRC's official store (iicrc.gilmoreglobal.com) or the IICRC Standards Subscription service (evantage.gilmoreglobal.com) -- it is not freely downloadable
  3. Cross-check that the remediation firm's technicians hold current IICRC certification tied to the applicable edition, since certification exams update alongside standard revisions
  4. Use S520's containment/negative-air and post-remediation verification framework to scope drywall/plaster removal and replacement extents, not just visible mold
  5. Check for state-specific mold remediation licensing requirements (e.g., Texas, Florida) that layer on top of the IICRC standard
