Board of Industrial Trades DC: What HVAC Technicians Need to Know
The Board That Controls Your License
The Board of Industrial Trades is the regulatory body that licenses refrigeration and air conditioning mechanics and contractors in the District of Columbia. It operates under the Department of Licensing and Consumer Protection (DLCP) — the agency that replaced DCRA's licensing functions when the old agency was dissolved in October 2022.
If you work in HVAC in DC, this board governs your professional credentials. It approves exam applications, issues and renews licenses, processes reinstatements, and handles disciplinary actions. The DOB is a separate entity — it handles building permits and inspections but has no authority over trade licensing.
What the Board Oversees
The Board of Industrial Trades covers several trades, not just HVAC. Electricians, plumbers, and steamfitters fall under its jurisdiction too. For refrigeration and air conditioning, the board manages four credential tiers:
- Apprentice mechanic — entry-level, supervised work only
- Journeyman mechanic — qualified to perform and supervise work under a master
- Master mechanic (limited) — systems up to 25 compressor horsepower
- Master mechanic (unlimited) — no capacity restriction
The board also issues trade contractor licenses to business entities and manages the $5,000 surety bond requirements.
How to Interact With the Board
Individual applications and renewals go through the Access DC portal — the online system where you submit experience verification documents, upload credentials, pay fees, and track your application status.
Business filings (entity registration, BBL) go through the separate BOSS portal. The contractor license application goes to the Board of Industrial Trades; follow the Board's current submission instructions after registering the entity on BOSS.
Board meetings are held periodically and are open to the public. Meeting minutes are published on the DLCP website. These minutes occasionally contain updates on regulatory changes, fee adjustments, or discussions about reciprocity agreements with other jurisdictions.

The Board's Role in Common Scenarios
Exam authorization. You cannot schedule a PSI exam until the board reviews and approves your application. This is where incomplete documentation — unsigned experience letters, missing EPA 608 certification, insufficient hours — causes delays.
License denials and appeals. If the board denies your application, it must issue a written Notice of Intent to Deny specifying the regulatory basis. You typically have 15-30 calendar days to file a formal appeal and request a hearing before the DC Office of Administrative Hearings. You can present supplemental evidence — verified tax returns, W-2 forms, union dispatch records — to demonstrate compliance.
Qualifying individual changes. When a contractor's designated master mechanic leaves the business, the contractor must notify the board immediately. Continuing to operate without a qualifying individual on file is unlicensed contracting.
Disciplinary actions. If you receive a show-cause order, consumer complaint, or disciplinary notice, the board has the authority to suspend or revoke your license. An attorney experienced in administrative law is worth consulting at this stage.
