$lap at ‘gay bias’ co-op bd.

A documentary film producer claims she was rejected by an Upper East Side co-op because she’s married to a woman.

Alison Amron, 59, had a deal to buy a $2.2 million penthouse at 333 E. 69th St. when the co-op board dismissed her application without even interviewing her, she claims in court papers.

Her application to the board for the all-cash sale went “above and beyond” what was required, with multiple personal and professional references, and included an introductory letter describing Amron as being “in a committed relationship with Mary Ellen for 22 years, and happily married to her for 10 of those years,” according to a Manhattan federal lawsuit.

Amron — known for the Emmy Award-winning Showtime series “Years of Living Dangerously” and the 2010 documentary “Fat, Sick & Nearly Dead” — offered to put four years’ worth of maintenance and assessment payments into escrow as a show of good faith but the board wouldn’t reconsider, she charges. The board didn’t give a reason for the rejection.

The three-bedroom, two-bath home in the doorman building included a large private terrace and floor-to-ceiling windows, according to a listing.

Co-ops in New York have wide latitude in rejecting potential residents.

With her previous apartment in contract to sell, Amron was forced to rent a Second Avenue apartment for nearly $10,000 a month, she said in the housing discrimination suit filed against the East 69th Street co-op. She’s seeking unspecified damages.

The co-op did not return messages.
