Cladding on the building failed safety tests in the wake of the Grenfell tragedy and worried leaseholders were facing having to pay the costs themselves.
But Barratt has now stepped forward following discussions with the government.
The company said it will cover future and backdated costs relating to employing a fire warden and the removal and replacement of unsafe cladding from the building.
Housing Secretary Sajid Javid, said: “I applaud Barratt Developments’ decision to cover the costs of fire safety works.
“They have listened to the concerns of Citiscape residents, engaged with government and have done the right thing.
“Other building owners and house builders in the private sector should follow the example set by Barratt Developments to protect leaseholders from costs and begin essential fire safety works.
“I want to see all leaseholders in this position get the peace of mind they deserve and I am keeping this under review.”
