New D.C. Mold Assessment and Remediation Rules

In nature, mold plays an important role in the life cycle by digesting waste. In homes, mold can digest building materials and cause health problems in inhabitants. Often taking hold of residences after a leak or flood, mold can add thousands of dollars in damages- turning a bad situation into a total disaster.

Due to these dangers of mold, the D.C. Department of Energy and Environment (DOEE) recently announced new regulations for those wishing to perform mold assessment and remediation work. Mold workers, contractors and landlords should be cognizant of the new requirements; violators can incur penalties upwards of $3,000.

For those who already hold mold licensure, the DOEE announced requirements before the assessment and remediation work may begin. They include:
  • Licensees must disclose any potential conflict of interest to any party affected by such conflicts
  • Licensees must specify containment protocol when the affected surface area is greater than ten square feet
Updates on the protocols for when an assessment or remediation is underway include:
  • Licensees must submit assessment verification reports to client and the remediation professional within 10 days of assessment
  • Licensees may not supervise more than 10 workers at one time

Not licensed yet? Here are the requirements for getting your Mold License in DC: 
  • Applicants must have taken a DOEE-approved examination within the previous 2 years. Exams are offered with the following courses:
  • Individuals must apply to the DOEE
  • Applicants must be at least 18 years old
  • Applicants must meet one of the following education and experience requirements:
    • at least a two-year associate's degree or equivalent, with at least 30 semester hours in microbiology, engineering, architecture, industrial hygiene, or a related field from an accredited institution and one year of documented relevant field experience
    • a certified industrial hygienist, professional engineer, professional sanitarian, certified safety professional or registered architect with at six months of relevant field experience
    • a high school diploma and three years of relevant field experience
Further information on licensing requirements and the application process is available on the DOEE's mold licensing homepage.


For landlords or property owners without licenses, the limits of what they are legally allowed to do for tenants is also outlined in the new regulations. Some changes include:
  • a license is required to perform assessment on areas greater than ten square feet
  • a license is required when collecting samples for mold analysis
  • a license is required for preparing mold remediation solutions for dwelling units not occupied by the individual

The entire document is worth reading for those interested in mold remediation and assessment in the DC area, and is available to read for free on the DC Department of Energy and Environment website.

Despite the new regulations on mold assessment and remediation in the D.C. area, earning licensure is still a great idea for individuals such as property owners.
