NYC Sanitation Commissioner Jessica Tisch is looking to clean up — on her posh three-bedroom Upper East Side duplex.

She and venture-capitalist husband Dan Levine have put their co-op at 9 East 79th St. up for sale for a cool $13 million.

It includes a formal dining room with vistas of Central Park, five bathrooms and a chef’s kitchen, according to a listing posted Tuesday.

It is among eight co-ops in a spacious, nearly century-old 15-story building off Fifth Avenue.

Under the co-op’s rules, purchases can’t be financed and must be paid for in cash.

The apartment also comes with jaw-dropping $14,962 monthly maintenance fee.

Tisch, an heiress whose family owns Loews Corp. and co-owns the New York Giants, and her hubby paid $8 million for the 4,000-square-foot space in 2011, when they bought it from Jessica’s billionaire parents, James and Merryl Tisch, records show.

Tisch first entered city government in 2008, when she began working in the NYPD’s counterterrorism unit.

In April 2022, Mayor Eric Adams appointed Tisch, 43, to her $243,171-a-year job as Sanitation Commissioner.

Tisch declined to discuss why she’s selling the pad, but was more than willing to discuss her job performance.

“You’re right that we’re moving – moving towards a cleaner city for every single New Yorker by emptying litter baskets 50,000 times more per week than before, cleaning the highways for the first time, and, perhaps most exciting of all, enacting a plan to containerize all trash across the five boroughs,” she said.

The news of Tisch and Levine putting the co-op up for sale was first reported by Crain’s New York Business.
