The Mixed-Exposure Household

Devon and Aisha own and occupy a 1968 four-bedroom colonial in Ohio. Their HO-3 shows Coverage A $450,000 and Coverage C $225,000. Three exposures surfaced in one week. Their 19-year-old son, Malik, lives in a dormitory at a state university 90 miles away and keeps a $4,000 bicycle and a $2,500 gaming computer in his room. Aisha inherited a duplex across town and rents both units to unrelated tenants; the duplex is titled in her name and generates $2,700 a month. Devon converted the detached garage into a pottery studio where he throws and sells mugs online, earning about $18,000 a year; the studio holds a $12,000 kiln, clay inventory, and finished pieces. Their agent proposes keeping one HO-3 and adding endorsements rather than buying separate policies. Aisha asks whether the duplex and the pottery operation are automatically covered as 'other structures' or 'business property' because they are on or near the residence premises.

1. For each of the three exposures-Malik at college, the duplex, and the pottery studio-identify the policy form or coverage part that should respond and explain why the current HO-3 does not automatically handle it.

Malik at college. Malik remains an 'insured' as a resident relative because the HO-3 treats a student who is away at school as a resident of the household. That means personal liability follows him, but it does not turn the dorm into the 'residence premises.' His property is covered under Coverage C, though the form's limitation for property usually at another residence may cap recovery; an HO-4 is cleaner if he moves into an apartment and signs a lease.

Duplex. The HO-3's 'residence premises' is the one-to-four-family dwelling where an insured resides. A rental duplex across town is not that. Coverage B ('other structures') applies only to structures on the residence premises, so the duplex is not covered. A DP-3 dwelling policy written for the landlord exposure, with its own liability and fair rental value coverage, is the right form.

Pottery studio. The detached garage is on the residence premises, but Coverage B excludes structures used in whole or in part for business. The kiln and inventory are business personal property, subject to the HO-3's $2,500 on-premises business property sublimit, not the $225,000 Coverage C limit. The business liability exposure is also excluded under Section II. A home business endorsement or a commercial policy is needed.

2. Aisha argues that the duplex is 'other structures' because she owns it and it is real property, and that the kiln is 'personal property' because it can be moved. Evaluate both arguments using the HO-3 definitions of 'residence premises,' Coverage B, and the business property limitation.

The 'other structures' argument fails for the duplex. Coverage B is tied to the residence premises, not to ownership. A separate rental property is a separate insurance exposure; the fact that Aisha owns it does not make it an other structure. If the duplex were a detached garage across the driveway, it could be an other structure-but not when it is a rented dwelling across town.

The 'personal property' argument is partly right but misses the business limitation. A kiln is personal property in the ordinary sense, but the HO-3 pays only $2,500 for business property on the residence premises and $500 for business property away from the premises. The clay inventory and finished mugs are stock in trade, not household contents. Coverage B also will not fill the gap because of the business-use exclusion. The label 'personal property' does not override the business sublimit.

3. What endorsements or separate policies would you recommend, and what coverage gaps remain if the family keeps only the HO-3 with a $2,500 business property limit?

Recommended structure: (1) keep the HO-3 for the residence, but add a home business endorsement covering the pottery stock, kiln, business liability, and loss of income; alternatively, write a commercial package for the pottery and keep the HO-3 residential. (2) Write a DP-3 for the duplex with $300,000 liability and fair rental value; confirm the tenants carry HO-4 policies. (3) Have Malik obtain an HO-4 if he leases an apartment; until then, confirm his status as an insured and schedule the bicycle if it exceeds the off-premises limit. If the family keeps only the HO-3 with the standard $2,500 business limit, gaps include the $12,000 kiln, inventory, business liability for a customer injured in the studio, and business income loss. The duplex is entirely uninsured. The agent should document the coverage conversation because the proposed 'one HO-3 plus endorsements' solution cannot cover the duplex.
