Confirm equipment breakdown is on the program at all, and get the schedule of covered equipment. Look for the generator, the chillers, the boilers and the elevators by name.
Compare the business income sublimit under equipment breakdown against the property policy figure. If they differ materially, understand why before you need it.
Add service interruption if your utility supply is anything other than highly reliable.
Ask in writing how resident relocation costs following an equipment failure would be handled, across equipment breakdown extra expense and the property policy. If nothing responds, that is a known retained exposure.
Keep the generator load testing records, the preventive maintenance schedule and the service contracts. Underwriters read them, surveyors ask for them, and after a failure a plaintiff will subpoena them.
Confirm fuel arrangements for extended outages, including contracted priority supply, because a generator with four hours of fuel is a four-hour solution.
Set spoilage limits against refrigerated medication value, not just food.
