This question addresses the specific technical wording found in Secondary Residence or more restrictive property forms regarding Detached Private Structures (Coverage B). While a primary Homeowners Comprehensive policy usually provides an additional 10% limit for each detached structure, certain forms (particularly those for seasonal or secondary residences) treat the 10% as an extension of the main dwelling limit that must be shared among all detached structures.
The RIBO Level 1 Blueprint requires brokers to understand Insurance Product Knowledge concerning proportional settlements. When a policy states that 10% of the dwelling limit applies to "all detached private structures," and a loss occurs to one of them, the insurer often uses a proportional calculation (Option B). For example, if the dwelling is insured for $200,000, the 10% extension is $20,000. If there are two sheds—one worth $15,000 and one worth $5,000—the $20,000 limit is "spread" across them based on their relative values. If the less valuable shed ($5,000) is destroyed, its "proportion" of the total detached value ($20,000) would be 25%. Thus, the maximum payout would be 25% of the $20,000 extension.
During Consulting and Advising, a broker must identify if a client has multiple valuable detached structures (like a boathouse and a guest cabin). If the proportional limit is insufficient, the broker must recommend scheduling the structures individually with their own specific limits. This demonstrates Risk Identification and Assessment, ensuring the client is not caught off guard by a limited payout during Claims Services.
