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.

Through Borough Directors and Deputy Commissioners working with tenant associations, parent groups, students, workers, communities of faith, grassroots activists and neighborhood residents, CAU actively propels Mayoral initiatives to further justice and opportunity for all New Yorkers.
