Sublimit
Definition
A sublimit is a smaller cap inside your policy that limits what it will pay for a specific type of loss or property, such as mold, water backup, cash or business equipment, no matter how high your overall coverage is.
What it means
Your declarations page lists your main limits, such as the dwelling and personal property limits. A sublimit is a lower ceiling that applies to one category within those limits.
The standard ISO homeowners form (HO 00 03) shows how this works. Its “Special Limits of Liability” section caps, for example, money at $200, theft of silverware at $2,500, and business property kept at home at $2,500. Endorsements add more sublimits. Limited fungi, wet or dry rot, or bacteria coverage (forms HO 04 26, 04 27 and 04 28) and limited water back-up coverage (HO 04 95) each pay only up to the amount scheduled on the policy.
Why it matters to your claim
Sublimits are where many claims come up short. A $400,000 dwelling limit does not help if your mold coverage is capped at a few thousand dollars. Before you start a large cleanup, find the endorsements and their limits on your declarations page so you know what your policy is likely to pay and what you may pay yourself. If you cannot tell which sublimit applies, ask your insurer or agent in writing. Our page on mold coverage shows how mold sublimits vary by carrier and state.
