What plumbing and HVAC contractors in South Carolina carry

Coverage Who usually asks Why it matters
General liability with completed operations · expected Property managers, GCs, homeowners' lenders, every commercial client A fitting that fails months later floods three floors. Completed operations is where plumbing and HVAC claims live.
Workers' compensation · expected Your state once you have employees; GCs and property managers Lifting, burns, confined spaces and ladders. Required by contract even where the state exempts the owner.
Commercial auto · expected Clients, GCs, your lender Service vans carrying parts and refrigerant are commercial use. Personal auto will usually not respond.
Inland marine (tools, gauges, recovery machines) Your own interest; equipment lessors Recovery machines and diagnostic tools are expensive and travel. Shop property coverage does not follow them.
Contractors pollution liability Commercial clients, GCs, some municipalities Refrigerant release, fuel oil spills, mold after a leak: general liability excludes most of it.
Umbrella / excess liability Commercial and multifamily contracts Raises the limits across GL, auto and employers' liability when a contract asks for more.
License and permit bonds Licensing boards and municipalities Required alongside the certificate to pull permits in most jurisdictions.

An employer that regularly employs four or more employees, full- or part-time, must carry workers' compensation; agricultural employers, railroads and businesses with an annual payroll below $3,000 are exempt. Whether a worker is an employee is decided by South Carolina's own test of control and independence, not by the form you file, and workers who fail it are added at audit.

Usually general liability, workers' compensation, commercial auto; General contractors typically ask for general liability and workers' compensation with a waiver of subrogation, often primary and non-contributory wording and commercial auto.

What auto coverage does South Carolina require for a plumbing or HVAC contractor's vehicles?

The state minimum limits: Bodily injury $25,000 per person / $50,000 per accident and property damage $25,000, with uninsured motorist coverage required at limits equal to the liability limits carried; underinsured motorist coverage must be offered.

Does my general liability cover water damage from my work?

Generally yes for damage to others' property caused by your work, through the completed-operations part of the policy. It does not cover redoing your own faulty work, and some policies narrow water damage, so read the forms.

Why do property managers want a waiver of subrogation?

If a leak you caused damages the building and the building's insurer pays, that insurer would normally come after you. A waiver on the manager's side of the deal and additional insured status on yours sort out who pays without litigation.

Is refrigerant handling a pollution exposure?

Insurers treat releases of refrigerant, fuel oil and similar substances as pollution, and standard general liability excludes most pollution claims. A contractors pollution policy fills the gap and is increasingly required on commercial work.
