The City Council approved a bill Thursday strengthening fire safety regulations in response to the Twin Parks North West building fire in the Bronx that killed 17 people in new January. 

The bill aims to improve inspections for self-closing doors and to make it easier for city officials to identify other instances of non-compliance with fire safety laws, council members said. 

It also seeks to improve communication between the Department of Housing Preservation and Development and the FDNY regarding fire safety violations, allowing each agency to use the data to improve building inspection processes.

This bill, which passed 50 to 0, also mandates HPD select 300 buildings to inspect for non-compliance on self-closing doors. The agency is also required to submit an annual report on detailing inspections. 

“The bill that we are voting on today was to honor the lives that were lost in the devastating fire that took place on January 9 at Twin Parks and to ensure that a tragedy like this never happens again,” Councilmember Nantasha Williams, who sponsored the bill, said at the council vote Thursday.

All 17 deaths, including those of eight children, were caused by smoke inhalation, according to the Committee on Housing and Buildings report on June 1. Dozens more were hospitalized with life-threatening injuries.

Officials said two doors that didn’t close allowed smoke to travel through the building: A door to the third-floor apartment where the fire originated because of a defective space heater remained open, allowing smoke to permeate through the building. The smoke was pulled into the stairwell, traveling up to the 15th floor, where the stairwell door was also left open, according to the committee report. 

“Following the tragedy at the Twin Parks North West residential building in the Bronx, it is imperative that we continue to take meaningful and impactful actions to safeguard the lives of all New Yorkers,” Speaker Adrienne Adams said in a statement on Thursday. “Strengthening inspection processes for self-closing doors will ultimately save lives, especially in higher risk buildings.”

The bill also requires HPD to provide information to the FDNY regarding fire safety violations dating back to 2017, which the FDNY must audit to inform its building inspection program.

This comes after a package of bills passed last month which also sought to strengthen the city’s fire safety laws. 

Those laws include requiring manual reinspection of buildings cited for self-closing door non-compliance by the city and mandates that landlords address any violation within two weeks, as opposed to the prior 21-day standard.

Landlords are also no longer able to certify door repairs without approval from a city inspector.
