BROOKLYN - Some Brooklyn residents held a rally Thursday over luxury housing that's popping up around the borough and the city.

They say that rent continues to skyrocket in areas like Downtown Brooklyn, Fort Greene and Boerum Hill, driving them out of the neighborhoods they grew up in. Protesters marched through the downtown area this morning, stopping at several luxury apartment buildings and demanding more affordable housing.

Organizers say they have about 75 groups involved from unions to community organizations, who are committed to both fighting for more affordable housing and preserving the affordable housing that already exists. They're asking that if these expensive apartments are going to continue to be built that affordable housing units also be made available in those buildings.

Protesters are hoping their message will help influence Mayor de Blasio's affordable housing plan, which comes out  May 1.
