A family of six say they are homeless after a council ordered them to leave two flats they built inside garage premises.
A 48-year-old grandfather, says that he spent the night in the cab of a lorry after he was evicted from the first floor flat he created on an industrial estate.
And the remaining five were reportedly forced to stay with a relative to avoid sleeping on the streets, Lincolnshire Live report.
The man's 26-year-old son, his son's fiancee and their children aged five, three and 11 months, who had been living in a flat on the ground floor, have also been told to move out.
The grandfather, who did not wish to say how long they had all been living at the Allenby Road Industrial Estate, said: "The council said that with immediate effect we cannot sleep here.
"We're homeless and the only solution would be to win the lottery.
"I just want my son and the kids to have a roof over their heads.
"It's disgusting how the council has handled this. It makes them look like they are doing their bit for community safety but why are they putting a family out on the street?"
The couple and the children have been offered bed and breakfast accommodation in Sleaford, Gainsborough and Grantham but the family says this is too far away.
The City of Lincoln Council and Lincolnshire Fire and Rescue inspected the flats following complaints and the homes were declared unfit to live in due to a number of fire and electrical risks.
A prohibition order was served on Wednesday meaning that no one is allowed to sleep in the flats.
Dan Moss, Group Manager at Lincolnshire Fire and Rescue, said a fire could "quickly and catastrophically" spread in these types of premises.
He said: "Industrial units are not designed for people to live in and don't have fundamental fire safety measures we would all expect to feature in our homes.
"This includes safe exits, fire-safe building materials and adequate ventilation, and commercial premises will contain hazards not usually found in homes.
"Ultimately, a fire could quickly and catastrophically spread in these types of premises, without adequate means of detection or escape for a family."
The 26-year-old dad-of-three, who asked to remain anonymous, told Lincolnshire Live: "I cannot afford to rent a council house or rent privately.
"I just tried to do the best to put a roof over the heads of my family.
"The council has offered us B&B accommodation but it's too far out so my fiancee and the kids spent Wednesday night at her sister's."
The grandfather insisted that the flats had been built to a good standard and showed Lincolnshire Live around his home which has two bedrooms, a lounge, kitchen, bathroom and a utility room.
He said: "I converted a unit into living accommodation. The work is not shoddy either.
"It was done by a builder friend and it's got gas central heating."
His dad, who owns the garage business, had been living on a boat but moved into a caravan on the industrial estate after his wife had a stroke.
The great-grandfather said: "It does not matter about my wife and I living in a caravan but there's three kids without a home."
Mark Sherwood, enforcement officer at City of Lincoln Council, issued this statement on Wednesday: “We have been made aware of a family occupying two units on the Allenby Industrial Estate.
“The council is working with Lincolnshire Fire & Rescue Service and the property owners to serve the occupiers with a prohibition notice to force them to leave the commercial property.
“Our officers inspected the two units and found a range of fire and electrical risks that make the property unfit for habitation.”
