Construction & Skilled Trades Background Checks

Construction companies often run dump trucks, flatbeds, and equipment haulers. Drivers who must hold a CDL for that work fall under federal DOT drug and alcohol rules. Before a new CDL driver performs safety-sensitive work, the employer must receive a negative pre-employment drug test result (49 CFR § 382.301).

The employer must also run a pre-employment full query of the FMCSA Drug and Alcohol Clearinghouse, which requires the driver's electronic consent (49 CFR § 382.701). These steps are separate from a criminal background check, so plan for both when a project needs new drivers.

California Government Code § 12954 (AB 2188), effective January 1, 2024, generally limits employer action based on off-duty cannabis use or tests that detect only non-psychoactive metabolites. The statute does not apply to employees in the building and construction trades.

That exception is narrow and does not replace federal DOT testing rules or other state laws. If you hire in several states, confirm each state's current rule before setting one drug policy for every crew.

Electricians, plumbers, HVAC technicians, and general contractors are licensed by state or local boards, and the rules differ by trade and location. The most reliable check is the issuing board's own lookup tool, recorded with the date you checked.

A license check confirms status on that date. It does not replace a criminal search or a motor vehicle record when the role calls for them.

If a background check from a consumer reporting agency may lead you not to hire someone, the Fair Credit Reporting Act requires a pre-adverse action notice first. That notice must include a copy of the report and the federal summary of rights (15 U.S.C. § 1681b(b)(3)).

After a final decision, a separate adverse action notice is required. Many states and cities add their own timing or individualized-assessment steps, so review the worksheet and your local rules before deciding.
