Mold and fungus coverage

Mold, mildew, wet or dry rot, and similar fungus are handled very differently from ordinary property damage on a community-association master policy. After a wave of mold litigation in the early 2000s, the standard property forms were rewritten to exclude fungus as a general matter and to add it back only through a limited fungus coverage endorsement carrying its own small annual aggregate sublimit, commonly landing in the $10,000 to $50,000 range against a building limit many times larger. Two features make this coverage behave unlike the rest of the policy. First, it is almost always tied to a covered water or peril event: the limited endorsement typically responds to mold only when the mold results from a covered cause of loss, so if the underlying water is itself excluded (flood, long-term seepage, or a maintenance-driven leak that was not sudden and accidental) the resulting mold is excluded along with it. Second, the sublimit is an annual aggregate, not a per-occurrence limit, so it is the most the policy pays for all fungus loss across the entire policy year no matter how many separate water events feed it. There is no statute that sets a mold sublimit; the recorded declaration determines which building components and which water exposures are the association's responsibility, and the endorsement has to be read against that allocation.

Mold is where a water claim quietly outruns the coverage that was supposed to answer for it. A community can carry a full replacement-cost building limit, a bought-up water backup sublimit, and still hit a fungus aggregate of only a few tens of thousands of dollars when remediation, containment, and reconstruction on a multi-unit water loss are priced out. The board should read three numbers together, not one: the fungus sublimit, whether it is a true annual aggregate that a single bad water year can exhaust, and the trigger language that ties mold coverage back to a covered cause of loss. The most common surprise is a mold loss that follows an excluded water source, a slow behind-the-wall leak found months later, or seepage the form treats as maintenance, where the water exclusion drags the mold exclusion along with it and the association funds the remediation itself, then passes the shortfall to owners as a special assessment. Sequence this with the water and water-backup review rather than treating it as a separate line, confirm whether the sublimit can be bought up for a community with older plumbing or a humid climate, and remember that owner HO-6 policies carry their own separate, usually small mold sublimit, so the gap does not disappear at the unit boundary either. The practical posture is to treat the fungus sublimit as a known, capped exposure to be managed through maintenance and moisture control, not as a limit that will make the association whole after a large water loss.

The specialty community-association markets carry mold as a limited fungus endorsement with a modest annual aggregate sublimit as standard, and a buy-up above the default is sometimes available but is priced hard against the community's water-loss history, plumbing age, and climate, because mold is the tail on the water exposure that drives this class. A tightening fungus sublimit or a new fungus exclusion at renewal is one of the earlier signals a carrier is repricing water and moisture risk on the account. Read the trigger, not just the number: an endorsement that responds only when the mold follows a covered cause of loss is close to no coverage where the underlying water source is itself excluded, so the water form and the fungus endorsement have to be evaluated together. No statute sets these terms; the framing here is qualitative best practice grounded in the standard ISO limited fungus coverage endorsements and the water-damage nexus, and this clause is intentionally informational (no evaluator rule) because no frozen ProgramIndicators field captures the fungus sublimit.
