Contractors in the Mid-Atlantic region face different licensing and insurance requirements in each state. Here is what general liability, workers' comp, and other coverages are required — and recommended — in each state Prominent serves.
Quick answer: All five states in Prominent's service area require contractors who employ workers to carry workers' compensation insurance, and most contractor licensing boards require general liability insurance before a license is issued or a permit is pulled. The specific thresholds vary by state, trade, and license type. Below is a state-by-state overview for contractors operating in Delaware, Pennsylvania, New Jersey, Maryland, and Virginia.
Contractors who lack required coverage face real consequences: license suspension, inability to pull permits, personal liability for worker injuries, and exposure to property damage claims with no defense. Project owners and general contractors increasingly require subcontractors to provide certificates of insurance before any work begins — and to name the project owner as an additional insured.
Understanding exactly what each state requires protects your license, your workers, and your business.
General liability: Delaware does not set a statewide minimum liability limit for all contractors, but the Division of Revenue and many local jurisdictions require proof of general liability insurance to obtain a business license. Most project owners and GCs require at least $1 million per occurrence / $2 million aggregate.
Workers' compensation: Required for any contractor with one or more employees. Delaware has no small-employer exemption. Sole proprietors may exclude themselves from coverage but are then personally liable for any work-related injury.
Additional requirements: Delaware requires home improvement contractors to register with the Division of Revenue and carry a surety bond. HVAC, plumbing, and electrical contractors must hold state-issued licenses with proof of insurance.

General liability: Pennsylvania's contractor licensing varies significantly by trade. The Home Improvement Contractor (HIC) registration, required for contractors doing residential work totaling $5,000 or more, requires proof of general liability insurance. Most counties and municipalities set their own permit requirements that include GL minimums. Standard project requirements are $1 million per occurrence / $2 million aggregate.
Workers' compensation: Required for virtually all employers in Pennsylvania with one or more employees. Unlike Delaware, Pennsylvania allows corporate officers of closely held corporations to exclude themselves from coverage under limited circumstances.
Additional requirements: Electricians (EL license), plumbers, and HVAC contractors are licensed at the municipal or county level in Pennsylvania rather than statewide. Each jurisdiction may set its own insurance requirements. State construction contracts typically require higher limits and additional insured endorsements.
Pennsylvania note: If you work across the border into other states, each state's coverage requirements apply to work done there, and your policy must provide coverage in those states.
General liability: New Jersey requires contractors who perform home improvement work to register as a Home Improvement Contractor (HIC) with the Division of Consumer Affairs. HIC registration requires general liability insurance of at least $500,000 per occurrence. Many project owners require $1 million.
Workers' compensation: Required for all employers in New Jersey. New Jersey has one of the broadest worker coverage requirements in the region and actively enforces compliance through the Division of Workers' Compensation.
Additional requirements: New Jersey Contractor Business Registration (CBR) is required for all contractors, separate from HIC registration. Electricians, plumbers, and HVAC technicians hold state licenses with insurance requirements set by the respective licensing boards.
New Jersey note: New Jersey's contractor landscape is among the most heavily regulated in the Mid-Atlantic region. Confirm CBR, HIC, and trade license requirements before beginning any project.
General liability: Maryland requires home improvement contractors to be licensed by the Maryland Home Improvement Commission (MHIC). MHIC licensure requires a minimum of $50,000 in general liability insurance, though most project owners and GCs require $1 million. MHIC also requires a surety bond.
Workers' compensation: Required for all employers in Maryland regardless of number of employees. As detailed in our [Maryland workers' comp guide](/blog/workers-comp-requirements-maryland), penalties for non-compliance include civil fines, criminal liability, and personal responsibility for injured workers' benefits.
Additional requirements: Maryland electricians, plumbers, HVAC technicians, and other trade contractors hold state licenses through the Maryland Department of Labor. Each license category has its own insurance requirements.
General liability: Virginia requires most contractors to be licensed by the Department of Professional and Occupational Regulation (DPOR) through the Board for Contractors. Licensing classes carry their own insurance requirements, and most commercial project owners and GCs set their own minimums — typically $1 million per occurrence or higher — regardless of the DPOR floor. Verify current requirements directly with DPOR before relying on any stated thresholds, as minimums can change.
Workers' compensation: Virginia requires workers' compensation for employers with three or more employees. This threshold is lower than most neighboring states but higher than Maryland's any-employee requirement. Independent contractors and subcontractors may be treated as employees for workers' comp purposes under Virginia law's "statutory employer" provisions — a contractor can be held responsible for a subcontractor's uninsured workers if injured on the job site.
Additional requirements: Virginia's statutory employer rule is one of the most important insurance considerations for Virginia GCs using subcontractors. Require a certificate of insurance from every subcontractor before work begins.
Regardless of what each state mandates at its minimum, most contractors working in the Mid-Atlantic region need:
For businesses that qualify, a [business owners policy (BOP)](/blog/what-is-a-business-owners-policy-bop) can bundle GL and property coverage cost-effectively. Contractors with employees should review their [workers' comp](/business-insurance/workers-compensation) coverage annually as payroll and employee counts change.
