The police cleared out protesters early Tuesday and arrested more than 200 people. They took protesters' belongings including clothing, sleeping bags and electronic gear to a city garage.
Protesters say some of their property was thrown away.
Adams said Sunday that no city agency has the right to take people's property without giving them receipts for it.
He said he would write a letter of protest to Mayor Michael Bloomberg and call for City Council hearings.
Adams also criticized the arrests Tuesday of journalists who were covering the protests.
Adams is a Brooklyn Democrat and a retired police captain.
