Due to a late amendment, a sprawling, 154-page condo-law bill that unanimously passed the House and Senate states that condominium residents in mixed-use buildings only own what has been given to them upfront in contracts drafted by developers.

That often includes only the units themselves, meaning residents living in condo-hotels could be forced to pay pricey maintenance fees and assessments levied by commercial operators for things like elevators, lobbies and pools, but without any say over the size of the bill, how their money is spent or how the assets are managed.
