Which of the following commercial license classifications is permitted to subcontract electrical work?

The B-1 General Commercial Contractor classification is correct because it is specifically designed to allow contractors to handle a variety of commercial projects, which can include the ability to subcontract specialized work such as electrical work. This classification encompasses broader responsibilities and qualifications, which includes oversight of various trades necessary for large-scale commercial projects.

In Arizona, subcontracting of specialized work like electrical installations typically requires either a specific license or the capacity to oversee licensed subcontractors effectively. The B-1 license allows for the management of these tasks under its broader scope, making it legally permitted for a contractor with this classification to hire and manage subcontractors who specialize in electrical work.

The other classifications, such as B General Residential Contractor, C Specialty Contractor, and B-2 General Commercial Contractor, either have limitations on the types of work they can oversee or do not typically encompass the full scope of responsibilities required for commercial electrical work. Thus, they would not have the same allowance to subcontract electrical tasks as a B-1 General Commercial Contractor does.
