DC Solar Contractor License Requirements (2026)

DC issues no standalone solar license. Solar PV is electrical work under D.C. Official Code §47-2853, now administered by the Department of Licensing and Consumer Protection (DLCP) Board of Industrial Trades — formerly DLCP, which was split in 2022 between DLCP (licensing) and the Department of Buildings (DOB, permits and inspections). Every solar business needs a DC Master Electrician as qualifying party plus a Basic Business License (BBL) under Home Improvement Contractor or General Contractor, and pulls electrical and structural permits through DOB. DC Solar For All and the SREC program effectively require NABCEP PV Installation Professional certification. Solar thermal hot water needs a DC Master Plumber.

DLCP (formerly DCRA) issues the Basic Business License (BBL) including the Home Improvement Contractor endorsement, and staffs the Board of Industrial Trades which licenses master and journey electricians, plumbers, steamfitters (HVAC), and refrigeration and air-conditioning mechanics in the District of Columbia.

Common Filing Mistakes

Based on the board's own instructions and the sources cited here, the problems below are what most often stall a District of Columbia Solar application.

Skipping the Basic Business License

Master Electrician alone does not authorize you to contract in DC.

Skipping NABCEP for SREC work

DC Solar For All and SREC registration effectively require NABCEP.

Missing the 12-hour CE

Mandatory every two years and audited.

Letting the HIC bond lapse

DLCP suspends licenses immediately upon bond cancellation.

Forgetting solar thermal is plumbing
