Fire crews were alerted to the blaze, at Tipton Conservative and Unionist Club, at 2.40pm on Friday.
The fire was contained to one room while the building sustained smoke damage, said West Midlands Fire Service [WMFS].
It comes after a cannabis factory, worth an estimated £1,000,000, was found there in June.
A spokesman for WMFS said: "We had a call at 2.40pm to a disused club on fire in the front room of the conservative club.
"There was smoke damage to parts of the building."
The owner of the building was contacted following the blaze.
It is unclear how the fire began. A total of 18 firefighters attended the scene.
Tipton Green councillor Ian Jones said: "It is very worrying that the building is in an area that hasn't been developed.
"I understand the reasons why because of the financial difficulties that developers face.
"As a result, it leaves buildings exposed to these type of things and people are rightly worried."
