Do you need a mold inspector license in Colorado?
Colorado does not license or register mold inspectors. Its climate ranges from the semi-arid Front Range (IECC 5B) to alpine high country (zone 7), and because the air is dry, amplification almost always traces to a point source — plumbing leaks, ice-dam meltwater, swamp-cooler over-humidification, or HVAC condensate — rather than ambient humidity. The Colorado Department of Public Health and Environment publishes mold and indoor-air guidance and issues no mold credential. Colorado inspectors typically hold a voluntary IICRC or ACAC certification.
Is a license required?
Colorado does not license mold inspectors or assessors at the state level. Inspectors typically hold a voluntary certification (such as IICRC or ACAC) rather than a state license.

Common questions
Do you need a license to be a mold inspector in Colorado?
No. Colorado issues no state mold-inspector license, so there is no state exam or registration to complete. Inspectors instead show competence through voluntary certification such as IICRC or ACAC and by following recognized industry standards.
Who regulates mold inspection in Colorado?
No single board regulates mold inspection in Colorado. The state's environmental and health agencies publish general mold guidance instead: https://cdphe.colorado.gov/.
