Amanda Bynes Moves Out of NYC Apt ... After Landlord Threatens Eviction

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.
