A Brooklyn homeowner hopes a mob of buyers will take a shot at this town house.

The three-family, 20-foot-wide residence at 21 Garfield Pl. was once home to Al Capone before he moved to Chicago in the ’20s and became “Public Enemy No. 1.” It’s listed for $2.85 million.

Capone gained infamy as a ruthless mobster in Prohibition-era Chicago running bootlegging, prostitution and gambling rings.

Today, the renovated, 20-foot wide townhouse looks nothing like it once did, said listing broker Bren Salamon, of Douglas Elliman.

While the exterior is nondescript, the interior has high end finishes. It includes a posh, three bedroom duplex with two and a half bathrooms and a garden. There’s two other additional units.

All are decked out with fancy chef’s kitchens and their own private outdoor spaces.

“If Capone were living here today he wouldn’t need bootlegging to make a living. The upper rental units can easily fetch $6,000 a month and Park Slope has terrific bars and restaurants,” Salamon said.
