Next door neighbours putting up with the stench, non-stop loud music, constant loitering and strange comings-and-goings at all hours pleaded with Harrow Council to help after the string of antisocial incidents.
When council officers raided the semi-detached house, they found the 12 shameless tenants living in "terrible danger" in the property, with no safe fire exit, overloaded extension cables and just a single toilet shared between them, with no water to flush away waste.
Harrow Council gave the landlord a one-week ultimatum to get rid of the tenants and agree to fix his unsafe house – which the local authority say he duly did.
Simon Baxter, divisional director for environment and culture at the council said: “These tenants behaved terribly – but they also lived in terrible danger.
"They were the landlord’s responsibility, and we will not tolerate our neighbourhoods becoming a haven for illegal and disgusting behaviour.
“Now his tenants are all gone, we’ll leave it to him to explain things to his long-suffering neighbours – and his bank manager.”
The state of the property was so bad that officers banned the use of the second floor until the property is brought up to scratch.
The local authority is now working closely with the landlord, whom Harrow Council refuse to name for legal reasons, to make sure it is made safe and operating with a House of Multiple Occupancy (HMO) licence.
If the property goes back into disrepair or becomes overcrowded, legal action will follow, Harrow Council said.
The property remains empty until repairs are completed by the landlord.
