Certificates of Insurance for Contractors in DE, PA, NJ, MD and VA: What You Actually Need to Bid

Why certificates hold up so many bids

You win the job, the GC sends over a contract, and the insurance section is two pages of requirements. The office wants a certificate by Friday. If your policy is not built to match, the certificate cannot fix it. That is where contractors lose time, lose bids, or worse, find out after a claim that they were not covered the way the contract required.

What a certificate is, and what it is not

The standard form is the ACORD 25, Certificate of Liability Insurance. It summarizes your policies, limits and dates. The form itself says it is issued "as a matter of information only," confers no rights on the certificate holder, and does not amend, extend or alter the coverage. Three practical points follow:

The endorsements contracts usually require

Most construction contracts ask for some combination of these standard ISO endorsements on your general liability policy:

Contracts often ask for matching wording on commercial auto, umbrella and workers' compensation as well. Send us the insurance section of the contract before you sign, and we will confirm what your policy already does and what needs to be added.

State rules contractors should know

Delaware. Every contractor, resident or nonresident, needs a Division of Revenue business license. Nonresident contractors must post a bond of 6% of contracts of $20,000 or more. Delaware's Contractor Registration Act requires contractors to register with the Department of Labor before performing construction services, and the application asks for proof of Delaware workers' compensation coverage. Delaware's workers' comp law also requires a contracting entity to obtain a certificate of insurance from each independent contractor or subcontractor and keep it for three years. If it does not, it can be treated as the insurer for that worker's workers' compensation claims.

Pennsylvania. Home improvement contractors must register with the Office of Attorney General unless their home improvement work totals less than $5,000 in a calendar year. Registrants must carry at least $50,000 of bodily injury and $50,000 of property damage liability coverage. Under Pennsylvania's Construction Workplace Misclassification Act, one factor for treating a worker as an independent contractor is that the worker carries liability insurance of at least $50,000.

New Jersey. Home improvement contractors must register annually with the Division of Consumer Affairs and carry commercial general liability of at least $500,000 per occurrence. Home improvement contracts over $500 must include a copy of the certificate of insurance and the insurer's phone number. New Jersey also presumes that people performing construction work are employees unless the legal test for independent contractors is met.

Maryland. Home improvement contractors licensed by the Maryland Home Improvement Commission must carry general liability insurance of at least $500,000. That minimum took effect October 1, 2024; it was previously $50,000.

Virginia. Contractors need a license from the Board for Contractors at DPOR. Class C covers single contracts over $1,000 and under $30,000, Class B covers $30,000 to under $150,000, and Class A covers $150,000 or more, with matching annual volume limits. Virginia does not set a general liability minimum in those license classes, but localities will not issue or renew a contractor's business license without written certification of compliance with Virginia's workers' compensation law. On public work, Virginia generally requires performance and payment bonds on nontransportation construction contracts over $500,000, and federal projects over $150,000 require bonds under the Miller Act.

A certificate checklist that saves you time

1. Send us the contract's insurance requirements before you sign.
2. Confirm limits, including any umbrella requirement.
3. Confirm the endorsements: additional insured (ongoing and completed operations), primary and noncontributory, waiver of subrogation, per project aggregate.
4. Collect certificates from every subcontractor before they start, and keep them.
5. Keep a master certificate on file with us so new holders can be issued quickly and updated at every renewal.
