Sublimit

A sublimit is a smaller cap inside your policy that applies to a specific type of loss. It is carved out of — not added on top of — the overall limit, so it is the most you can collect for that particular peril, regardless of how high the headline limit is.

Sublimits can be flat dollar amounts (e.g., $100,000 for flood) or a percentage of the main limit (e.g., 25% for debris removal). They commonly apply to flood, earthquake, spoilage, water backup, electronic data/equipment, and — in professional and management lines — punitive damages or specific claim types. Because they don't stack on the main limit, sublimits are a frequent source of coverage-gap surprises at claim time.

Businesses with concentrated exposures — a restaurant's refrigerated stock, a retailer's high-value signage, a shop in a flood-prone ZIP — should confirm the sublimit is adequate and, if not, buy it up by endorsement. Always check whether limits are shared or separate, since a sublimit loss is paid within the overall limit and can erode aggregate limits depending on wording.
