NEW YORK (CBSNewYork) — Mayor Bill de Blasio held a town hall meeting on affordable housing Wednesday night, but some residents expressed concern that the units will not come soon enough.

As WCBS 880’s Stephanie Colombini reported, the mayor touted his affordable housing plan at the Upper West Side event, particularly the part that dedicates 10,000 units for senior citizens.

But many of the seniors at the meeting told the mayor they are concerned they will be homeless long before the housing becomes available, because landlords are pushing them out now.

De Blasio said there are ways residents can fight back.

“If you believe you are being harassed or forced out of your apartment illegally, all you have to do nowadays is call 311,” the mayor said.

De Blasio said city employees can connect residents to lawyers, who at no charge will help determine if there has been any foul play and look into whether rental assistance is an option.

The event was held at the Lincoln Square Neighborhood Center, 250 W. 65th St.
