We could not confirm a Michigan 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 Michigan 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 Michigan 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.
