When a person buys a condo, they automatically own anything that is inside of it. The space upon which the building sits and its entire exterior are owned by the HOA or condominium association. So, the outer parts and the roof are all the responsibility of the HOA and are thus assumed to be properly insured. Those who own condos are directly responsible for all the plumbing, appliances, and items within being suitably insured. Usually, homeowners insurance would be a bit of overkill in these situations. However, the typical renters insurance might very well be insufficient This is exactly why condo insurance came into being. It provides the happy medium for protection for those who are condo owners/dwellers.
