This question explores the concept of Material Change in Risk under Statutory Condition 1 (Misrepresentation) and Statutory Condition 4 (Material Change). In the RIBO Level 1 Blueprint, a broker must be able to identify when a change in the use of a property significantly alters the "physical or moral hazard" that was originally underwritten.

Standard homeowners' policies are designed for private residential use by the owner and their family. Transitioning a home into a short-term rental (like an Airbnb) introduces a "commercial" element: there is higher foot traffic, guests are less familiar with the property's safety features, and the homeowner's liability exposure increases significantly. Because this change would likely lead an insurer to charge a higher premium, apply different terms, or decline the risk altogether, it is considered a material fact.

If the insured fails to notify the insurer, they have breached the contract. In the event of a loss (e.g., a guest accidentally starts a kitchen fire or sues for an injury), the insurer has the legal right to deny the claim (Option B) or even void the policy from the date the material change occurred. As part of Consulting and Advising, a broker must proactively ask clients about any plans for home-sharing. The RIBO Competency Profile emphasizes that the broker’s role is to ensure the "suitability" of the coverage. By informing the insurer, the broker can help the client obtain the necessary "Home-Sharing Endorsement" or a specific commercial policy. This ensures the client remains protected and the broker avoids an Errors and Omissions (E&O) claim for failing to advise the client on the consequences of non-disclosure.
