Illustrative scenarios, not actual agency losses or Ohio cases.
A visitor’s fall leads to an injury claim involving the specified playground surfacing. Design, installation, and maintenance responsibilities are disputed.
Illustrative claim amount: $300,000.
Preserve specifications, substitutions, approvals, and maintenance-scope boundaries rather than assuming the design caused the injury.
At resale, a fence and driveway are found to encroach on adjoining property. The parties dispute the earlier survey’s boundary depiction.
Illustrative claim amount: $75,000, including legal fees.
Research and field records may be needed years later; prior-acts eligibility matters when carriers change.

We could not confirm a Ohio board for interior designers on an official source, so we make no claim about it.
No. Published claims and market data for design professionals are reported nationally, not by state. We show cited national figures so Ohio firms can see the broader market; your own quote depends on your firm.
Carrier materials we cite list the limit and deductible ranges shown in the table. Availability in Ohio is confirmed during underwriting.
A retroactive date is the prior-acts boundary on a claims-made policy: services performed before that date may fall outside coverage even when the claim arrives during the current policy.
Most architecture firms carry professional liability insurance because clients, owners and contracts commonly ask for it and because design-error allegations can arise years after a project closes.
Generally no: general liability is not a substitute for professional liability when the allegation is a design error.
Usually not: additional-insured status is typically a general liability request, and professional liability policies generally do not add clients as additional insureds.
