What it does
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
The Department of Commerce (Commerce) administers various laws, including building codes, that promote safety in public and private buildings and in the subsystems of those buildings. To that end, Commerce issues various licenses, permits, registrations, and other credentials (licenses) to persons engaged in the construction trades, such as electricians and plumbers. Commerce also issues licenses in connection with the administration of other laws relating to public safety, such as those regulating fireworks and the storage of flammable liquids.
This bill requires Commerce to regulate the business of installing and maintaining thermal system insulation in commercial and industrial buildings and in residential buildings that contain four or more residential units. The bill defines thermal system insulation as a product used in a heating, ventilating, cooling, plumbing, or refrigeration system (heating or cooling system) to insulate any hot or cold surface on or in a building. The bill requires Commerce to license most persons who install and maintain thermal system insulation in heating or cooling systems (mechanics). The bill also requires Commerce to employ a state thermal system insulation inspector (state inspector). The bill establishes a thermal system insulation council (council), which recommends to Commerce the requirements for the licensure of mechanics. The council must also provide other advice to Commerce, including recommending training and continuing education requirements for mechanics.

Under the bill, the state inspector must have at least ten years of experience as a mechanic and must have successfully completed an apprenticeship program in installing and maintaining thermal system insulation. The state inspector must inspect buildings to determine whether the buildings comply with standards established by Commerce for the installation and maintenance of thermal system insulation (state standards). The state inspector must also keep complete and accurate records of all inspected buildings and give notice of noncompliance to the owner of every building who fails to comply with state standards. The bill authorizes the state inspector to enter and inspect buildings and to issue orders requiring the owner of a building to make repairs or alterations necessary for the building to conform to state standards. Under the bill, the state inspector must also provide assistance and information to building inspectors who inspect buildings for compliance with the standards established by Commerce under this bill.
The bill establishes minimum licensing requirements for thermal system insulation mechanics. Under the bill, a person may not obtain a mechanic's license unless he or she has acquired a specified amount of experience installing and maintaining thermal system insulation and passed a written examination approved by Commerce or has successfully completed an approved apprenticeship program.
The licensing requirement under the bill does not apply to a person who makes only minor repairs to thermal system insulation.
The bill allows Commerce to waive any licensing requirement for mechanics for a person who is licensed in another state in which the standards for licensure are at least as strict as the bill's requirements. The bill also allows Commerce to waive any licensing requirement for experienced mechanics who submit evidence satisfactory to Commerce that the mechanic is qualified for licensure. The bill further provides that Commerce may not renew a license issued to a mechanic unless the mechanic completes an approved continuing education course during the previous license period.
The bill authorizes Commerce to assess directly a forfeiture by issuing an order against any person who installs, or contracts to install, insulation products without a license or who fails to comply with an order issued by the state inspector.
