One number on your policy is probably small. Your building's deductible probably isn't.
Condo insurance looks simple. The association insures the building, you insure your stuff, and everyone gets on with life. That story holds up until the building has a serious problem. In Missouri that's often a hailstorm, high wind, a tornado warning that turns real, or a winter cold snap that bursts pipes across several units.
When a loss exceeds the master policy limits, or the master policy has a large deductible that somebody has to pay, the board can levy a special assessment and split the cost among every owner. Now it's your bill, in an amount you didn't choose. Some master policies use a percentage wind and hail deductible, calculated on the building's insured value. Run it once with round numbers: for example, a community insured for $10 million with a 1 percent wind and hail deductible would owe $100,000 before the master policy pays on a storm claim. Split among 50 units, that's about $2,000 per owner.
Your HO-6 has a coverage built for exactly this, called loss assessment. The default limit on many policies is small. Raising it often costs relatively little. One more piece of fine print to ask about: some policies cap the portion of an assessment that comes from the master deductible, no matter how much loss assessment coverage you bought. We check that clause by name.
Condos aren't as common around Sullivan as single-family homes, but plenty of our neighbors own a unit or townhome elsewhere, or commute toward the St. Louis area and live in one. Either way, the right approach is the same: start with the master policy declarations page and your declaration, then build the HO-6 to fit the gap they leave. We explain the coverages to you and let you pick what works for you. Bring the paperwork.
