Odor Control Certification Requirements by State
Requirements for odor control work vary by state — some states license the trade, many don’t regulate it at all. This page covers all 50 states: licensing notes, demand, and typical earnings for each. The NISCR Odor Control Certification is a professional credential that proves verified training in any state; where a license or federal credential is required, it complements — it does not replace — those requirements.
