(a) The installation or repair of any underground facilities or piping which connects to and furnishes water for the water-based fire protection system shall be performed only by a licensed utility contractor, fire protection sprinkler contractor, or licensed plumber in accordance with the minimum fire safety standards adopted by the Commissioner. The installing contractor shall be responsible for the installation of proper underground facilities and piping which provide an adequate flow of water from the fire protection water supply to the water-based fire protection system.

(b) Evidence of inspection shall be given to the owner or his or her representative in the form of a letter indicating the inspector or certificate of competency holder and the license number or certificate number.

(c) Before any local building official shall issue any license or building permit which authorizes the construction of any building or structure containing a water-based fire protection system, such local official shall require a copy of a valid fire protection sprinkler contractor license from the fire protection sprinkler contractor. The fire protection sprinkler contractor shall be required to pay any fees normally imposed for local licenses or permits, but the local official shall impose no requirements on the fire protection sprinkler contractor to prove competency other than proper evidence of a valid certificate of competency, as issued by the Commissioner.

(d) Nothing in this chapter limits the power of a municipality, county, or the state to require the submission and approval of plans and specifications or to regulate the quality and character of work performed by contractors through a system of permits, fees, and inspections otherwise authorized by law for the protection of the public health and safety.
