On an unendorsed Illinois HO-3, Coverage C (personal property) is typically provided at what percentage of the Coverage A dwelling limit?

Why this is the answer

On the unendorsed Illinois HO-3, Coverage C (personal property) is automatically set at 50% of Coverage A (dwelling). Coverage B (other structures) is 10%, Coverage D (loss of use) is typically 30%, and liability and medical payments are separate coverages. Insureds with above-average contents value can endorse higher Coverage C limits. The 50% figure is industry-standard and reflected in IL-issued ISO HO-3 forms.
