Insurance When Starting Your Own Design Firm
Written and reviewed by Michael LaBarbera, licensed insurance agent
A new design practice needs insurance matched to its own professional services and contracts rather than an assumption that a former employer’s policy protects it. We use your proposed work, staffing and responsibilities to prepare a submission to markets quoted through our agency.
What are the key facts?
| No. The retroactive date is a prior-acts boundary; the policy start date begins the current insurance period. | [Design Professional Liability — The Hartford] |
| They need the scale and composition of the professional work for their own underwriting definitions. | [Great American — Design professional liability application] |
| Different services and projects create different underwriting exposures, so an application asks how the firm’s work is distributed. | [Great American — Design professional liability application] |
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.
How should a firm choose its professional liability limit?
Start with contract requirements and project exposure, then compare available policy limits and how defense expenses affect them.
Per-claim and aggregate limits answer different questions. A requested limit is not confirmation the whole contractual obligation is insured. Consider multiple claims, prior work, exclusions, sublimits and the cost-sharing obligation stated in the policy.
Why does the application ask about subconsultants?
Subconsulted services and insurance arrangements help the underwriter understand professional responsibility and the firm’s exposure.
Identify what is delegated, who contracts with whom, billings and how evidence of insurance is collected. A subconsultant’s policy does not by itself erase the primary firm’s contractual obligations.
Why do carriers ask for billings instead of only a revenue range?
They need the scale and composition of the professional work for their own underwriting definitions.
Great American’s application distinguishes professional billings, subconsultants and specified reimbursables. A quick lead-form range is useful for triage but is not a substitute for a carrier-ready financial schedule.
Prepare for review
Identify the new legal entity, start date, anticipated billings, planned projects and any prior work for which you retain responsibility. Separate new-firm work from former-employer projects.
Insurance terms vary by form, endorsement and underwriting. These explanations do not approve a contract or determine coverage for a particular claim.
