Connecticut will require mold remediators to hold IICRC, NORMI, or equivalent certification and follow S520 starting October 1.
Connecticut signed mold-remediation reform: effective Oct 1, contractors can't perform mold remediation unless certified by IICRC, NORMI, or an approved equivalent, and must follow the ANSI/IICRC S520 standard.
Why it matters
State certification mandates raise the floor, they push out unqualified cut-rate competitors and make your certifications a legal moat, not just a marketing badge.
Our assessment
A certification mandate lands as a compliance cost, and for a small shop it is one more line item. It is also a wall. Every state that licenses mold work pushes out the operators winning on price alone, and the certified shops inherit that volume. Get your team's credentials current before October, then put the standard number on your proposals so the difference is visible.
