Mr Spacey, whose prolific career came to an abrupt halt in late 2017 after several allegations emerged from young men who had encountered the actor in their teens, stood at the front of a small whitewashed court on the island of Nantucket for the first pre-trial hearing. The judge set another hearing for 4 March, and ordered Spacey to stay away from the young man in question.
A judge denied Spacey's bid to avoid appearing in person on Monday.
Kevin, who faces a potential maximum sentence of five years in prison, did not enter a plea, nor did he speak according to THR.
Upon entering the courtroom, Spacey sat whispering and occasionally chuckling with his attorney, Alan Jackson. Defense attorneys asked the court to preserve cell phone data and other text messages from the victim from the date of the incident until six months afterward, which defense attorneys said would be "likely exculpatory" for Spacey.
Authorities say Spacey got an 18-year-old bus boy drunk, and fondled the teen under his trousers without consent, while visiting The Club Car in Nantucket, Massachusetts in July 2016.
His appearance in a crowded courthouse surrounded by television trucks came at what is normally a quiet time of year on the island, a former whaling hub.
Spacey is one of dozens of men in the entertainment industry and politics who have been accused of sexual misconduct in the past 10 months, partly as a result of the #MeToo social media movement.
Spacey apologized for inappropriate conduct with Rapp.
The controversy has led to Spacey being axed from a number of roles, including from House of Cards and the 2017 film All the Money in the World, which was re-shot without him.
Spacey is accused of sexually assaulting the teenage son of former Boston WCVB-TV news anchor Heather Unruh at a Nantucket bar in July 2016.
She also said how her son left the restaurant when Spacey went to the bathroom.
In court documents, Spacey's lawyers called the accusations "patently false" and noted that prosecutors have no witnesses to the alleged groping.
After meeting the actor and telling him he was 23 years old - the legal drinking age is 21 in MA - he said he started drinking first beer and then whiskey with Mr Spacey at his urging.
United Kingdom police are also investigating several allegations that centre around his time serving as artistic director at London's Old Vic theatre.
The victim's "unsubstantiated, after-the-fact claims of sexual assault are patently false" and other details about their interaction that night "at best. describes two people engaged in mutual and consensual flirtation, nothing more, " the attorneys wrote.
