New Jersey contractor registration and DPMC classification
Contractors and subcontractors on covered New Jersey public works must hold Public Works Contractor Registration. To bid state building projects, firms also need DPMC classification, renewed every 24 months.
Public Works Contractor Registration
Under the Public Works Contractor Registration Act, contractors and subcontractors that bid on or perform public works covered by the prevailing wage law must register with the New Jersey Department of Labor and Workforce Development. That includes subcontractors at every tier.
DPMC classification
The Division of Property Management and Construction (DPMC), in the Department of the Treasury, manages construction for many state agencies. A firm must be classified by DPMC before it can bid DPMC projects. Classification covers specific trades (DPMC calls them disciplines) and sets an aggregate rating limit. DPMC's how-to-do-business page says firms reclassify every 24 months.
Home improvement and trades
Residential home improvement contractors register with the Division of Consumer Affairs. Electrical, plumbing and HVACR work is licensed by trade boards.
What the directory shows
This site's New Jersey directory lists 1,203 firms with a New Jersey address from DPMC's classified contractor search. Firms classified in general construction or design-build disciplines are shown as general contractors (340); the others as trade contractors (863).
