Council-certified Residential Mold Inspector
Required: 2 years experience as a home inspector or licensed pest control operator

Program Summary:

A Council-certified Residential Mold Inspector (CRMI) locates and identifies mold as part of a home inspection. A CRMI conducts a mold inspection using industry standard sampling techniques and verifies the presence or absence of mold contamination. A CRMI provides an efficient screening to clear a property of microbial issues. A CRMI's report is therefore an important part of a real estate transaction.

A CRMI does not perform mold remediation. When mold contamination is present, a CRMI can recommend a certified professional to develop and execute a mold remediation protocol. A CRMI has verified knowledge of standards and sampling techniques used in real estate transactions.

The CRMI examination covers standards published by the Indoor Environmental Standards Organization (IESO), an ANSI-accredited standards body. All candidates for the CRMI must demonstrate intensive knowledge of IESO standards governing mold inspection and home inspection.

To maintaint the Council-certified Residential Mold Inspector (CRMI) designation, certificants must:


The CRMI certification is accredited by the Council for Engineering and Scientific Specialty Boards (CESB), a nationally recognized independent accreditation body. ACAC certifications are the ONLY designations in the indoor air quality field to earn CESB accreditation.

The CRMI designation is fully supported by ACAC but is no longer offered to new candidates.
