A B - General Residential Contractor must subcontract which type of work?

A General Residential Contractor, often referred to as a B Contractor, typically is required to subcontract specialized work that requires specific licenses. This includes both plumbing and electrical work, as these trades have specific state-mandated licensing requirements that are distinct from general contracting.

Among the choices listed, the correct answer indicates that a general residential contractor must specifically subcontract electrical work. This choice reflects the additional qualifications and licensing necessary to perform electrical installations and repairs safely and according to the law.

It's also important to note that while roofing can sometimes fall under the scope of a general contractor's ability to perform work, it does not universally require subcontracting to a licensed roofer in the same way that plumbing and electrical does. Thus, the requirement to subcontract specifically for electrical work highlights the specialized knowledge and compliance necessary for such trades to ensure safety and adherence to regulations.
