The new bill will be introduced Tuesday by Councilman Ben Kallos, who represents the Upper East Side. If passed, it would give a building owner three months, with the possibility of a three-month extension, to make repairs to a facade so that scaffolding can be removed in a timely manner. If the work is not completed in that time, the city will step in to do it, and charge the owner for the work. The proposal would allow exceptions for factors such as bad weather, permit delays or in cases where removing scaffolding would be deemed dangerous to public safety.

“A specific timeline for landlords to get the work done will finally work toward holding someone accountable for scaffolding that goes up and never comes down,” Mr. Kallos said.

While the bill is likely to draw support from many residents and businesses, it faces strong opposition from many building owners. Carl Hum, a senior vice president for the Real Estate Board of New York, a leading real estate trade group with more than 17,000 members, said the proposal was “ill conceived and should be reconsidered.”

Frank Ricci, the director of governmental affairs for the Rent Stabilization Association, which represents 25,000 building owners and managers, said that owners sometimes do not have the money on hand to make costly repairs.
