A licensed C-10 electrical contractor advertises that it can also perform general roofing work, although it does not hold a C-39 roofing classification. This advertising is:

Explanation

§7027.1(a) makes it a misdemeanour for any person to advertise for construction work covered by the chapter unless that person holds a valid licence in the classification so advertised, with the single allowance that a licensed building or engineering contractor may advertise as a general contractor, and §7027.1(c) adds a fine of $700 to $1,000 on top of any other punishment. §7059.1(a) attacks the same conduct from the name side, barring a business name that indicates the licensee is qualified in classifications its licence does not carry. So holding a C-10 buys no right to advertise roofing, which is (a)'s mistake; the trades being adjacent is beside the point, which is (b)'s; and no dollar figure makes advertising outside a classification lawful, which is (c)'s — the $1,000 in §7048(a) is about who needs a licence at all, not about what a licensee may advertise, and §7048(c) withdraws even that exemption from anyone who advertises as a contractor. §7030.5 separately requires the licence number in all of it.
