ANSI/IICRC S520 Mold Remediation

ANSI/IICRC S520 Standard and IICRC R520 Reference Guide for Professional Mold Remediation

IICRC has published a newly revised ANSI-approved ANSI/IICRC S520 Standard for Professional Mold Remediation and IICRC R520 Reference Guide for Professional Mold Remediation (3rd edition, 2015). To purchase the ANSI/IICRC S520: 2015 and IICRC R520: 2015 visit the IICRC Webstore.

IICRC has initiated the revision of the ANSI/IICRC S520 and IICRC R520 in order to make additional changes and ensure consistency with the ANSI/IICRC S500 Standard. Those interested in participating on the S520/R520 Consensus Body or Chapter Committees should open and fill out the S520 Application Form, and email it back to IICRC Standards Director, Mili Washington at

The ANSI/IICRC S520 is a procedural standard for the remediation of mold damaged structures and contents. The ANSI/IICRC S520 is based on reliable remediation and restoration principles, research and practical experience, and attempts to combine essential academic principles with practical elements of water damage restoration for technicians facing “real-life” mold remediation challenges. The S520 and R520 are written for use by those involved in the mold remediation industry, and is the result of collaboration among microbiologists and other scientists, public health professionals, industrial hygienists, remediation contractors, restoration service companies, cleaning and restoration training schools, trade associations that service the professional restoration industry, allied trade-persons and others with related professional and practical experience.

ANSI/IICRC S520-2015 Standard and IICRC R520 Reference Guide is published as two separate documents: the standard itself and a supplementary reference guide. The procedural standard is supported by the reference guide. The intent is to use the principles outlined in the reference guide as a tool to better understand and apply the standard itself. However, the reference guide is not considered part of this standard.

The S520 Consensus Body Chair is Jim Pearson and Vice Chair is Rachel Adams.
