Mold in a Condo: what your HO-6 and the master policy may (and may not) pay for
Mold is one of the most common surprises after a Condo leak, and one of the most limited coverages on a typical HO-6 policy. Many policies exclude mold outright or cap it at a small sublimit, and the association’s master policy may only respond to part of the problem. This guide explains the usual limits, why the cause of the water matters, and what to do first. For who usually owns what in the building, start with HO-6 vs master policy.

How policies commonly limit mold
Wording varies a lot by insurer and state, but owners often find one of these on their HO-6:
- A full exclusion for mold, fungi, or wet rot, with narrow exceptions or none
- A sublimit that caps mold remediation and related repairs at a fixed dollar amount, often far below the cost of opening walls and floors
- Coverage only when mold follows a covered loss, such as a sudden pipe burst, and not when it comes from humidity or poor maintenance
- An optional endorsement some insurers sell to raise the mold limit for added premium
Why the cause of the water matters
Policies usually treat a sudden, accidental discharge of water very differently from long-term or repeated seepage. A burst supply line you report the same day is a much stronger claim than a slow drip under a sink that went unnoticed for months. Wear and tear, maintenance problems, and ongoing humidity are commonly excluded. That is why routine checks of supply lines, water heaters, and AC drain lines are worth the time. See guide #4: water damage, who pays.
Master policy vs owner
If mold starts in a common element, such as a riser, roof, or exterior wall, the association may be responsible for some of the repair under the declaration and the master policy. Interior finishes, upgrades, and your belongings may still fall to you and your HO-6, and the master policy has its own mold wording and deductible. If the water came from a neighbor’s unit, their policy may also be involved. Ask your manager which documents govern before work starts.
What to do first
- Stop the water if you can, and note when you discovered it.
- Notify the manager or association and your insurer promptly.
- Photograph the area before anything is removed.
- Dry the area quickly; many policies expect reasonable steps to prevent further damage.
- Keep invoices for drying, testing, and remediation.

FAQ: Condo mold and insurance
Short answers for Condo owners. Always verify with your policy, your association, and a licensed agent in your state.
Does a Condo HO-6 policy cover mold?
Sometimes, and often only in a limited way. Many HO-6 policies exclude mold on its own, or cover it only when it results from a covered sudden water loss, and many cap mold remediation at a small sublimit. Some insurers sell an endorsement that raises that limit. Read the mold or fungi wording on your own policy and ask your agent.
Is mold from a slow leak covered?
Usually less likely. Policies commonly exclude damage from long-term or repeated seepage and from wear, maintenance, or humidity problems. Mold that grows after a sudden burst pipe that was reported quickly is a different situation from mold that grew behind a wall for months.
Who pays for mold that starts in a common pipe or another unit?
It depends on the declaration, the master policy, the facts, and possibly the other owner's policy. The association may be responsible for common elements, while finishes and contents inside your unit may still fall to you. See the water damage guide on this site and your association's documents.
What should I do if I find mold after a leak?
Stop the water if you can, report it to the association or manager and to your insurer promptly, take photos, and dry the area quickly. Prompt reporting matters because many policies have conditions about timely notice and preventing further damage.
Can I raise my mold limit?
Some insurers offer endorsements that increase mold or fungi coverage for an added premium; others do not. Ask a licensed agent what your current sublimit is and whether a higher limit is available.
Is this guide insurance or legal advice?
No. Coverage Gap Report is general education for Condo owners. Coverage, limits, exclusions, and association responsibilities vary by state, insurer, and association. Verify with your policy, your association documents, and a licensed insurance professional in your state.
Check your mold limit before you need it
Most owners never look at the mold wording until there is a leak. Related reading: guide #1: HO-6 vs master, guide #4: water damage, guide #8: loss of use, guide #11: filing a Condo claim, and guide #13: renovating your Condo.
