DC Contractor Licensing & Trade Credential Guide

Washington, DC uses a layered licensing system. DLCP Business Licensing handles contractor business categories such as General Contractor/Construction Manager and Home Improvement Contractor. The Board of Industrial Trades regulates electrical, plumbing/gasfitting, refrigeration/air-conditioning, elevator, asbestos, and operating/steam-engineer credentials. DOB controls construction permitting and property records, while DOEE adds environmental permit gates for asbestos and lead work.

01 · The DC rule

License the business. Then verify the trade.

In the District, contractor qualification is not a single-license check. Start with the DLCP business-license category, then add any required Board of Industrial Trades credential, DOB permit validation, and DOEE environmental approval.

What does a DC contractor actually need?

DLCP lists General Contractor (A, B, C, G & H)/Construction Manager and Home Improvement Contractor as contractor/construction business activities. DLCP also states that a subcontractor working in DC needs its own applicable business license; the prime contractor’s license does not extend to the subcontractor’s business.

When the work is electrical, plumbing/gasfitting, refrigeration/air conditioning, elevator-related, asbestos, or certain operating/steam-engineer work, verify the corresponding occupational or trade credential through the Board of Industrial Trades.

02 · Credential map

Four DC systems control contractor eligibility.

The practical routing model is layered. Each system answers a different question before a lead should be treated as contractor-qualified.

07 · Fast answers

Fast answers for contractors & lead buyers.

Five DC-specific answers to the questions most likely to affect contractor qualification and lead routing.

01Does a subcontractor working on one DC job need its own business license?+

Yes. DLCP states that a subcontractor in the District is required to obtain the applicable Basic Business License; the prime contractor’s license does not cover the subcontractor’s contracting business.

02Which DC business-license categories cover general construction work?+

DLCP lists General Contractor (A, B, C, G & H)/Construction Manager and Home Improvement Contractor under Contractor and Construction Services. The exact category should be confirmed in BOSS/Scout before routing.

03Who licenses electricians, plumbers, HVAC/refrigeration and elevator trades in DC?+

The Department of Licensing and Consumer Protection’s Board of Industrial Trades regulates electricians, plumbers/gasfitters, refrigeration and air-conditioning mechanics, elevator trades, asbestos workers, and steam/operating engineers.

04How should I verify a DC contractor before sending a lead?+

Verify the business license in Scout or BOSS, verify any occupational/professional trade license through DLCP OPL, and confirm permit/property records through DOB Scout/eRecords. For regulated environmental work, also confirm the applicable DOEE permit or license layer.

05What extra licensing layer applies to home-improvement contractors?+

DLCP lists a Home Improvement Contractor business license with requirements that include liability insurance, a home-improvement contract, criminal-history documentation, and a $25,000 surety bond, in addition to other business-registration and tax requirements.
