Professional vs General Liability for Design Firms
Written and reviewed by Michael LaBarbera, licensed insurance agent
Professional liability addresses qualifying allegations about professional services; general liability addresses different premises, operations and product exposures subject to its form. We review both policies rather than treating one as a substitute for the other.
What are the key facts?
| It addresses claims alleging negligent acts, errors or omissions in insured professional services, subject to the policy’s terms. | [Design Professional Liability — The Hartford] |
| Some insurers allow it, but adding an additional insured to professional liability extends your coverage to another party and can increase your risk; general liability should be reviewed separately. | [Additional Insured on Professional Liability Policies — The Hartford] |
| A certificate summarizes insurance; it does not create an endorsement or expand the policy’s coverage. | [What Is a Certificate of Liability Insurance? — The Hartford] |
What does professional liability cover for a design firm?
It addresses claims alleging negligent acts, errors or omissions in insured professional services, subject to the policy’s terms.
The insured-services definition matters as much as the firm’s job title. Disclose changes in disciplines, construction responsibilities and project types before relying on a policy for new work.
Can an owner be an additional insured on professional liability?
Some insurers allow it, but adding an additional insured to professional liability extends your coverage to another party and can increase your risk; general liability should be reviewed separately.
Professional liability covers the insured design firm’s professional services. Owner requirements may combine general and professional liability in one paragraph. Separate those requirements and seek agent and attorney review instead of assuming a certificate fixes them.
Does a certificate change the insurance policy?
A certificate summarizes insurance; it does not create an endorsement or expand the policy’s coverage.
Compare the contract with the declarations and applicable endorsements before signing. A certificate issued for an RFP does not prove every indemnity, additional-insured or duration requirement is satisfied.
What to send for an agent review
Separate professional-services requirements from general liability requirements in the owner’s insurance schedule. Send both declarations and the contract wording for review.
The policy form, endorsements and reported facts control coverage. This comparison is educational; it is not an underwriting decision, a carrier ranking or legal approval.
