Jani Lane
had been frequenting L.A. area hotels in the weeks before he died -- and trashed one of his rooms so badly, that he was BANNED from the hotel ... TMZ has learned.

Sources tell us Lane had been kicked out of the Hilton Woodland Hills sometime in the last month -- after hotel employees noticed that he had torn his room apart.

We're told Jani was "not rude" about the situation -- and understood why he had to leave.

Lane, we're told, had recently earned a reputation in the area for trashing his hotel rooms -- one source tells us he had been kicked out of multiple places within the last few weeks of his life.

As TMZ first reported, Lane died at a Comfort Inn hotel in L.A. on Thursday evening. Investigators have not released an official cause of death ... but report that a half-bottle of vodka and prescription drugs were found in the room.
