A contractor performs work outside the classifications listed on the license. This is best characterized as what?

B&P §7059 confines a licensee to the classifications held; exceeding them is a violation, and under §7031 the contractor may be barred from collecting for work it was not licensed to perform. (a) treats a license as a general permit rather than a scope. (b) is the genuinely hard distractor: work that is truly incidental and supplemental to the licensed trade is allowed, so the item turns on whether the work is incidental — if it is a separate trade, it is not. (d) borrows the §7048 minor-work exemption, which excuses the absence of a license on a small standalone job and does nothing about scope.
