GENERAL CONTRACTING x TRENTON x NEW JERSEY

General Contracting contractors in Trenton, New Jersey.

General contracting in Trenton, New Jersey, is primarily governed by state-level registration requirements through the Division of Consumer Affairs. As a contractor, your primary responsibility is ensuring that your Home Improvement Contractor (HIC) registration is active and that you carry the mandatory $500,000 in liability insurance. Failure to register or maintain insurance can lead to significant fines and legal complications under the New Jersey Consumer Fraud Act.

At the municipal level, Trenton requires strict adherence to the Uniform Construction Code (UCC). Before beginning any project, you must secure the necessary permits from the City of Trenton Department of Inspections. It is the contractor's responsibility to ensure that all work is inspected at the appropriate intervals and that any subcontractors utilized on the job hold the necessary state-level trade licenses.
