Fife Council is spending more than £225 million on its homes over the next three years.
The investment is aimed at ensuring the local authority continues to reach the Scottish Housing Quality Standard.
It will also help deliver the new energy efficient standard for social housing.
Improvements will include new bathrooms and kitchens, the replacement of doors and windows and new central heating systems.
Maintenance has already been carried out to roofs, door entry systems, roughcast, heating and electrical systems.
Energy efficiency works have also been completed.
Councillor Judy Hamilton, spokeswoman for housing and building services, said she was delighted with the work.
“We invested over £70 million last year to make this happen,” she said.
“These improvements are funded from rent money raised from our tenants and we talk and listen to our tenants to ensure that we are delivering on their priorities.
“We’re proud of the progress being made here in Fife and these improvements will make real differences for tenants across Fife as well as allow us to offer warmer, drier, healthier homes.”
More than £76m will be spent on wider investment works next year, including major improvements to retirement housing in Cardenden and Lochgelly.
Work to ensure all houses continue to be of the highest quality and meet new energy efficiency standards will cost just over £28m.
Around 85% of the council’s homes already meet energy efficiency standards.
