Does homeowners insurance protect against delinquent condo fees?

This is not a normal type of coverage, per se.

Depending on the reason an owner does not pay assessments, you may be able to purchase protection. For example, if your home is not habitable based on a protected disaster, your coverage may include monies sufficient to pay your assessments, which you still owe.

Your broker or insurance carrier can answer your specific question, given your specific situation.
