Yep. Even if the pool is shut down and the gym is locked up, this is not a negotiable element of condo ownership. As a partial owner of the common areas in your building, it’s your responsibility to keep paying to keep them running smoothly. Plus, if you don’t pay, your condo association could hit you up for the costs later -̶ they have lien rights on your property. If you still don’t pay, they could foreclose on your unit. It’s not worth the risk. But if there are excess dues, that’s not a bad thing: the association can use them to make improvements, or even lower next year’s monthly fees.
