Handyman insurance in New Jersey, where the state answers first
New Jersey is the state where "does a handyman need insurance" is answered by regulation: home improvement work on residential property requires registration with the Division of Consumer Affairs, and registration requires commercial general liability coverage of at least $500,000 per occurrence, with workers compensation unless exempt. The certificate is not optional paperwork; without it the application does not process.
Registration first, and insurance is inside it
Most states leave a solo handyman's insurance decision to the market. New Jersey wrote it into the registration regime: home improvement contractors, and the definition reaches construction, remodeling, renovation, repair, installation, and demolition work on residential buildings, register with the Division of Consumer Affairs, and the registration requires proof of commercial general liability insurance in a minimum amount of $500,000 per occurrence, plus workers compensation unless exempt (NJ Division of Consumer Affairs, HIC registration instructions). The practical sequence follows: the agent conversation comes before the registration filing, because the certificate rides with the application.
The coverage itself is the sole operator's set this site walks on the handyman insurance page: general liability at the required limit as the core, tools and the truck around it, workers compensation per your staffing. For the opposite regulatory posture, where the state draws a dollar line instead of demanding a certificate, see California. Verify the current registration requirements with the Division directly; they have been revised before and will be again. Or start at the overview.
