Under California law, which license classification allows a contractor to build a 15-story office building?
Correct Answer
A) Either Class A or Class B
Both Class A and Class B contractors can construct buildings. Class A focuses on engineering projects while Class B covers general building construction.
Why This Is the Correct Answer
Both Class A (General Engineering) and Class B (General Building) contractors are authorized to construct multi-story commercial buildings. Class A contractors handle large-scale engineering and infrastructure projects, while Class B contractors specialize in general building construction including commercial structures. Either license alone qualifies a contractor to build a 15-story office building, making 'Either Class A or Class B' the most complete and accurate answer.
Why the Other Options Are Wrong
Option B: Class B - General Building
This is partially correct — Class B General Building contractors can build a 15-story office building — but the answer is incomplete because it excludes Class A contractors, who are also authorized to perform such work. Choosing only Class B ignores the full scope of Class A authority.
Option C: Class A - General Engineering
This is partially correct — Class A General Engineering contractors can certainly undertake large commercial construction — but the answer is incomplete because it excludes Class B General Building contractors, who are equally authorized for this type of project.
Option D: Class C - Specialty
Class C Specialty contractors are limited to specific trades (e.g., electrical, plumbing, roofing). They are not authorized to act as the prime contractor on a whole-building project like a 15-story office building without a Class A or B license.
Memory Technique
Think of it as the 'A or B' rule for big buildings: A = Anything large-scale engineered, B = Buildings in general. Either one gets you into the high-rise. Only C (Specialty) is left out — C is for Components, not complete structures.
