A blaze-hit mill is to be demolished.
Up to 25 firefighters tackled a blaze at a derelict mill in Dowker Street, Milnsbridge, early today.
Crews took an hour to bring the blaze under control but the inside was gutted.
Inspectors ruled the building unsafe and demolition crews moved in to flatten it.
Residents say the boarded-up building has been repeatedly targeted by firebugs and is a den for drug-taking.
Firefighters from Huddersfield, Meltham, Slaithwaite and Rastrick were called out at just after 7.30am.
A couple in their 30s with a young baby had to be evacuated from the house next door.
Fire station manager Scott Donegan, of West Yorkshire Fire Service, said: “The whole building had gone up in flames.
“Fortunately the adjoining house was not damaged and the family have been allowed to go back.
“People have forced entry into the building and we believe the cause was youths playing and setting fires in it.
“Fires like this cause us significant difficulties due to the unstable structure.
“They also require a lot of firefighters and they endanger anyone playing in these buildings.
“This building was boarded up for a reason and we ask people, especially children, not to play inside them.”
Police have launched an investigation.
Firefighters remained at the scene most of the day and stood by as the demolition got underway.
In August 2011 there was another big blaze in the former Taylor Valves factory nearby when residents also had to leave their homes.
The site, which is due to be developed into 36 three and four-bedroomed terraced and semi-detached homes and apartments, still sits empty with boards around it.
Katherine Doyle lives off Armitage Road, next to the rear of the former Taylor site, and was glad the mill was coming down.
“Kids have been coming down the alleyway to get into the Taylor site then access the mill for at least the six years I’ve been living here,” she said.
“They light fires, take drugs and are just a big nuisance, so hopefully they will no longer be able to use the building and the site as somewhere to go.
“I just hope they get on with developing the land because it’s a huge waste at the moment.”
