I was an insurance guy....many associations and unit owners have no idea who is responsible for what when there is a fire in a condo or town home association. Many (damn near all) unit owners are underinsured and almost all associations don't know what their responsibility is until the fire trucks leave.
Don't count on association assessments to cover it either. It is confusing stuff that gets taken way too lightly until something happens.
For example. Who pays the fire department for a smoke alarm to your unit ? Who pays for smoke damage to the paint on the walls inside your unit ? Who owns the fixtures outside the paint on the walls (kitchen cabinets, carpet, toilet, sink.....) Who insures the carpet that you installed ? Any improvements that you made beyond the paint on the wall? How much insurance do you carry for the stuff outside of the paint ? Kitchen cabinets, plumbing fixtures, hardwood floors, built in appliances add up to many, many thousands of dollars. Who insures the $10,000 Cambria countertop you installed ? Who insures the jacuzzi tub ? It is installed, but who insures the fixtures ? How about the $10,000 bill to get the trees cleaned up in the common area after a thunderstorm ? What if the sewer backs up and ruins the flooring (who owns it and who has insurance to cover it) I'll bet 99.9.5% of condo unit owners, associations and their insurers don't know or take it into consideration until after a loss. Unit owners buy the place and take out a HO-6 for their personal belongings which only provides an extra 10% for their interest in their ownership of the unit. That is never enough......
Unit owners don't forget, associations that cover the commons have deductibles on the association policy and you may (will) be assessed for that portion of the loss too.
Don't wait until after a loss to find out what is your responsibility. This goes for liability insurance too. Don't blame your agent if you don't have enough coverage.
