Asbestos licensing in District of Columbia

In the District of Columbia, asbestos abatement businesses need a District business license and a Clean Hands certificate, and DOEE issues permits for regulated abatement projects to contractors with the required credentials. Asbestos workers and supervisors should hold a District-issued license. DOEE's asbestos program leaves out residential buildings with four or fewer dwelling units, including single-family homes, though federal and other rules may still apply. We did not find a public roster, so ask for the license on record and check DOEE's site for current requirements.

Lead licensing in District of Columbia

The District of Columbia's Department of Energy and Environment certifies business entities that perform lead-based paint abatement and related activities, and it issues permits for lead abatement and renovation work. Renovation, repair and painting that disturbs old paint is covered by EPA's federal Lead-Safe program. The department posts a list of certified companies, so you can check the certification on record, and EPA has a locator for renovation firms. Check the agencies' sites for current requirements.

Radon licensing in District of Columbia

In the District of Columbia, anyone who charges for radon screening, testing or mitigation must be listed as proficient by EPA or hold a proficiency certificate from an organization approved by the Mayor. This is a certification rule rather than a license issued by the city. The Department of Energy and Environment recommends certification from AARST or the National Radon Safety Board and asks you to request proof before work begins. Check the department's site for current requirements.
