The rule most consumers don't know
DC does not bar one licensee from doing both. DOEE proposed exactly that rule as §3204.5(j) in 2018 and dropped it from the final rule adopted 19 April 2021, on the reasoning that requiring separate professionals could be more burdensome and costly for landlords and could delay remediation for tenants. What DC imposes instead: a licensee may not assess or remediate a property in which they or their company hold a financial interest (20 DCMR §3204.5(b)); may not pay or accept a referral fee between mold licensees (§3204.5(a)); and must disclose any known or potential conflict of interest to affected parties (§3204.4(c)).
In plain terms: the person who inspects your mold problem cannot be the person you pay to fix it. The assessor writes the protocol; an independent remediator executes it. This protects you from a contractor inventing work for themselves — and it is the law in every US jurisdiction that licenses mold work.
Worth knowing right now
DC's licensed-professional list is required by statute (D.C. Code §8-241.03(c)). DOEE licenses individuals, not companies.
