Maryland Contractor Certificate of Insurance Checklist
A certificate of insurance (COI) is often needed before a contractor can start a commercial job. It is also easy to misunderstand. The certificate provides a snapshot of specified insurance information; the policy and actual endorsements control coverage. A COI is not proof that every requirement in a contract has been satisfied.
Before requesting a certificate
- Send the exact insurance exhibit. Attach the contract section listing the additional insured, primary/noncontributory, waiver, completed-operations or cancellation-notice wording. Avoid paraphrasing complex requirements in a text message.
- Check the legal names. Confirm your insured entity, the contracting customer and each specifically required additional insured. Similar project names or related LLCs are not interchangeable.
- Review limits. Check general liability, commercial auto, workers’ compensation and any umbrella/excess coverage against the contract. A contract minimum is not necessarily your legal licensing minimum or a recommendation for adequate coverage.
- Check operations and locations. A contract for work in a warehouse, on a roof or involving excavation might not match the operations used for underwriting the current policy.
- Confirm endorsements. Ask whether the required additional-insured and waiver endorsements exist and whether completed-operations coverage is requested. A certificate holder and an additional insured are not the same thing.
- Check subcontractors. Collect their actual insurance information and review contracts before they begin. Their coverage does not automatically replace yours.
- Allow processing time. Insurers or agencies may need time to review or issue endorsements. Do not assume a certificate can legally expand coverage immediately.
Important Maryland trade-specific checks
The rules are not interchangeable. Maryland’s State Board of Electricians lists general liability and property-damage requirements for insured master/qualified-agent status. The State Board of Plumbing and HVACR Board have their own requirements. Licensed home-improvement contractors have a separate $500,000 general liability minimum under Maryland Business Regulation §8-302.1, as amended effective October 1, 2024. A statewide licensing requirement does not replace a customer’s contract requirement. Verify your particular status with the applicable regulator.
When your COI request gets rejected
Ask which requirement is missing: limit, policy form, entity name, named insured, endorsement, certificate holder or effective date. Do not edit a certificate yourself. Send the actual contract and current policy information to your licensed agent for review.

What to send when a project manager rejects your certificate
A rejected COI request does not always mean the policy is invalid. Sometimes a contractor has supplied proof of coverage but not the specific documentation the contract requires. Before resending the same certificate, separate these issues:
- Wrong name or project: Verify the contract's exact legal entity, certificate holder and additional-insured parties.
- Missing endorsement: A certificate's remarks do not create additional-insured, waiver or primary/noncontributory coverage by themselves.
- Limit mismatch: Check the actual declarations and available umbrella or excess policy terms; do not promise to increase limits without insurer approval.
- Trade or scope mismatch: The business may need to explain an operation that was not included in the application or policy class.
- Timing: Verify effective dates and any project completion or ongoing-operations requirements.
Ask the project manager to identify the exact insurance exhibit item they believe is missing. Share that section with the agency. If a policy change is required, coverage changes depend on carrier acceptance and effective-date confirmation. For more context, see Maryland general liability and Maryland contractor insurance.
