An organization that supports affordable housing for the poor is joining a coalition that is pushing back against efforts to overhaul the state’s Scaffold Law.

Real Affordability for All is joining the larger Scaffold Safety Coalition, the groups will announce later today.

“We cannot build the housing New Yorkers need on the backs of injured workers,” said Maritza Silva-Farrell, spokesperson for RAFA. “The Scaffold Safety Law is an important protection that helps keep construction workers safe and out of harm’s way. We must not cut corners on safety and put workers lives at risk in order to provide quality, affordable housing for our city’s residents.”

Real Affordability for All is a coalition of smaller organizations itself, comprising more than 50 groups that seek to address homelessness, the New York City Housing Authority and preserving and developing affordable housing.

Adding to the coalition comes as business groups are mounting an effort to scale back the Scaffold Law, which those organizations contend makes it harder — and more expensive — to do business in New York.

With a housing groups joining the pro-Scaffold effort, the campaign is trying to push back against the claims that the law makes it more expensive for residents in the state.
