The Mayor's Community Affairs Unit (CAU) is the fundamental connection between City Hall and New York City residents throughout the five boroughs.

The primary mission of CAU is to establish deep partnerships with communities in order to actively engage and mobilize New Yorkers in City government.

To this end CAU is directly responsible for integrating government into communities by working with Mayoral agencies to ensure the effective and efficient deployment of government services and the Mayor’s top policy priorities and initiatives.
