(A) It is unlawful to engage in fire sprinkler work under a name other than the exact name that appears on the license issued pursuant to this chapter. "Engaging in fire sprinkler work" includes marketing, advertising, using site signs, submitting contracts, and performing work. This requirement does not include advertising on vehicles, which may use an abbreviated version of the license name so long as the advertising is not misleading.

(B) A licensed fire sprinkler contractor may be a subcontractor to another licensed fire sprinkler contractor who has the contract with a client to engage in fire sprinkler work.

(C) A licensed fire sprinkler contractor who has the contract for fire sprinkler work may subcontract water line installation to a licensed water and sewer lines contractor when the waterline work is outside a structure and is included in the fire sprinkler system.

(D) A licensed fire sprinkler contractor may subcontract fire sprinkler work regulated under this chapter to another licensed fire sprinkler contractor and must approve and be responsible for the work the subcontractor performed. Both fire sprinkler contractors may be held accountable by the board for improper work. A fire sprinkler contractor may not bid or perform any general or mechanical work that requires licensure.

(E) A fire sprinkler contractor may submit a bid for a project which includes fire/burglar alarm work if fifty percent or more of the work to be performed is fire sprinkler work. The fire/burglar alarm work must be subcontracted to a licensed fire/burglar alarm contractor. The fire sprinkler contractor is responsible for the work performed by the fire/burglar alarm contractor. Both licensees may be held accountable by the board for improper work. The determination of the cost of the work involved on a project must be determined by the total cost of construction involved in the bid or contract or work to be performed.
