Amanda Bynes is currently packing up her NYC apartment ... and moving somewhere else ... after her landlord threatened to evict the actress claiming she's a disrespectful rule-breaker ... TMZ has learned.
Sources at the apartment tell us ... Bynes got a letter from building management earlier this month explaining that her lease would be terminated ... because she's a building nuisance.
We're told management made the decision after getting several complaints of marijuana smoke coming from her apartment -- "morning, noon and night." Sources say she was also seen smoking weed in the hallways.
FYI -- it's a non-smoking building.
As TMZ previously reported, Bynes is a fan of the herb -- she was photographed smoking weed around Los Angeles last year.
Sources say Amanda wasn't going to wait around and challenge management's decision -- and instead decided to simply find somewhere else to live.
The moving trucks are currently on-site. So far, no word on where she plans to live next.
